The mud at the bottom of B.C. fjords reveals that solar output drives
climate change - and that we should prepare now for dangerous global
cooling.
Politicians and environmentalists these days convey the impression that
climate-change research is an exceptionally dull field with little left
to discover. We are assured by everyone from David Suzuki to Al Gore to
Prime Minister Stephen Harper that "the science is settled." At the
recent G8 summit, German Chancellor Angela Merkel even attempted to
convince world leaders to play God by restricting carbon-dioxide
emissions to a level that would magically limit the rise in world
temperatures to 2C.
The fact that science is many years away from properly understanding
global climate doesn't seem to bother our leaders at all. Inviting
testimony only from those who don't question political orthodoxy on the
issue, parliamentarians are charging ahead with the impossible and
expensive goal of "stopping global climate change." Liberal MP Ralph
Goodale's June 11 House of Commons assertion that Parliament should have
"a real good discussion about the potential for carbon capture and
sequestration in dealing with carbon dioxide, which has tremendous
potential for improving the climate, not only here in Canada but around
the world," would be humorous were he, and even the current government,
not deadly serious about devoting vast resources to this hopeless
crusade.
Climate stability has never been a feature of planet Earth. The only
constant about climate is change; it changes continually and, at times,
quite rapidly. Many times in the past, temperatures were far higher than
today, and occasionally, temperatures were colder. As recently as 6,000
years ago, it was about 3C warmer than now. Ten thousand years ago,
while the world was coming out of the thousand-year-long "Younger Dryas"
cold episode, temperatures rose as much as 6C in a decade -- 100 times
faster than the past century's 0.6C warming that has so upset
environmentalists.
Climate-change research is now literally exploding with new findings.
Since the 1997 Kyoto Protocol, the field has had more research than in
all previous years combined and the discoveries are completely
shattering the myths. For example, I and the first-class scientists I
work with are consistently finding excellent correlations between the
regular fluctuations in the brightness of the sun and earthly climate.
This is not surprising. The sun and the stars are the ultimate source of
all energy on the planet.
My interest in the current climate-change debate was triggered in 1998,
when I was funded by a Natural Sciences and Engineering Research Council
strategic project grant to determine if there were regular cycles in
West Coast fish productivity. As a result of wide swings in the
populations of anchovies, herring and other commercially important West
Coast fish stock, fisheries managers were having a very difficult time
establishing appropriate fishing quotas. One season there would be
abundant stock and broad harvesting would be acceptable; the very next
year the fisheries would collapse. No one really knew why or how to
predict the future health of this crucially important resource.
Although climate was suspected to play a significant role in marine
productivity, only since the beginning of the 20th century have accurate
fishing and temperature records been kept in this region of the
northeast Pacific. We needed indicators of fish productivity over
thousands of years to see whether there were recurring cycles in
populations and what phenomena may be driving the changes.
My research team began to collect and analyze core samples from the
bottom of deep Western Canadian fjords. The regions in which we chose to
conduct our research, Effingham Inlet on the West Coast of Vancouver
Island, and in 2001, sounds in the Belize-Seymour Inlet complex on the
mainland coast of British Columbia, were perfect for this sort of work.
The topography of these fjords is such that they contain deep basins
that are subject to little water transfer from the open ocean and so
water near the bottom is relatively stagnant and very low in oxygen
content. As a consequence, the floors of these basins are mostly
lifeless and sediment layers build up year after year, undisturbed over
millennia.
Using various coring technologies, we have been able to collect more
than 5,000 years' worth of mud in these basins, with the oldest layers
coming from a depth of about 11 metres below the fjord floor. Clearly
visible in our mud cores are annual changes that record the different
seasons: corresponding to the cool, rainy winter seasons, we see dark
layers composed mostly of dirt washed into the fjord from the land; in
the warm summer months we see abundant fossilized fish scales and
diatoms (the most common form of phytoplankton, or single-celled ocean
plants) that have fallen to the fjord floor from nutrient-rich surface
waters. In years when warm summers dominated climate in the region, we
clearly see far thicker layers of diatoms and fish scales than we do in
cooler years. Ours is one of the highest-quality climate records
available anywhere today and in it we see obvious confirmation that
natural climate change can be dramatic. For example, in the middle of a
62-year slice of the record at about 4,400 years ago, there was a shift
in climate in only a couple of seasons from warm, dry and sunny
conditions to one that was mostly cold and rainy for several decades.
Using computers to conduct what is referred to as a "time series
analysis" on the colouration and thickness of the annual layers, we have
discovered repeated cycles in marine productivity in this, a region
larger than Europe. Specifically, we find a very strong and consistent
11-year cycle throughout the whole record in the sediments and diatom
remains. This correlates closely to the well-known 11-year "Schwabe"
sunspot cycle, during which the output of the sun varies by about 0.1%.
Sunspots, violent storms on the surface of the sun, have the effect of
increasing solar output, so, by counting the spots visible on the
surface of our star, we have an indirect measure of its varying
brightness. Such records have been kept for many centuries and match
very well with the changes in marine productivity we are observing.
In the sediment, diatom and fish-scale records, we also see longer
period cycles, all correlating closely with other well-known regular
solar variations. In particular, we see marine productivity cycles that
match well with the sun's 75-90-year "Gleissberg Cycle," the
200-500-year "Suess Cycle" and the 1,100-1,500-year "Bond Cycle." The
strength of these cycles is seen to vary over time, fading in and out
over the millennia. The variation in the sun's brightness over these
longer cycles may be many times greater in magnitude than that measured
over the short Schwabe cycle and so are seen to impact marine
productivity even more significantly.
Our finding of a direct correlation between variations in the brightness
of the sun and earthly climate indicators (called "proxies") is not
unique. Hundreds of other studies, using proxies from tree rings in
Russia's Kola Peninsula to water levels of the Nile, show exactly the
same thing: The sun appears to drive climate change.
However, there was a problem. Despite this clear and repeated
correlation, the measured variations in incoming solar energy were, on
their own, not sufficient to cause the climate changes we have observed
in our proxies. In addition, even though the sun is brighter now than at
any time in the past 8,000 years, the increase in direct solar input is
not calculated to be sufficient to cause the past century's modest
warming on its own. There had to be an amplifier of some sort for the
sun to be a primary driver of climate change.
Indeed, that is precisely what has been discovered. In a series of
groundbreaking scientific papers starting in 2002, Veizer, Shaviv,
Carslaw, and most recently Svensmark et al., have collectively
demonstrated that as the output of the sun varies, and with it, our
star's protective solar wind, varying amounts of galactic cosmic rays
from deep space are able to enter our solar system and penetrate the
Earth's atmosphere. These cosmic rays enhance cloud formation which,
overall, has a cooling effect on the planet. When the sun's energy
output is greater, not only does the Earth warm slightly due to direct
solar heating, but the stronger solar wind generated during these "high
sun" periods blocks many of the cosmic rays from entering our
atmosphere. Cloud cover decreases and the Earth warms still more.
The opposite occurs when the sun is less bright. More cosmic rays are
able to get through to Earth's atmosphere, more clouds form, and the
planet cools more than would otherwise be the case due to direct solar
effects alone. This is precisely what happened from the middle of the
17th century into the early 18th century, when the solar energy input to
our atmosphere, as indicated by the number of sunspots, was at a minimum
and the planet was stuck in the Little Ice Age. These new findings
suggest that changes in the output of the sun caused the most recent
climate change. By comparison, CO2 variations show little correlation
with our planet's climate on long, medium and even short time scales.
In some fields the science is indeed "settled." For example, plate
tectonics, once highly controversial, is now so well-established that we
rarely see papers on the subject at all. But the science of global
climate change is still in its infancy, with many thousands of papers
published every year. In a 2003 poll conducted by German environmental
researchers Dennis Bray and Hans von Storch, two-thirds of more than 530
climate scientists from 27 countries surveyed did not believe that "the
current state of scientific knowledge is developed well enough to allow
for a reasonable assessment of the effects of greenhouse gases." About
half of those polled stated that the science of climate change was not
sufficiently settled to pass the issue over to policymakers at all.
Solar scientists predict that, by 2020, the sun will be starting into
its weakest Schwabe solar cycle of the past two centuries, likely
leading to unusually cool conditions on Earth. Beginning to plan for
adaptation to such a cool period, one which may continue well beyond one
11-year cycle, as did the Little Ice Age, should be a priority for
governments. It is global cooling, not warming, that is the major
climate threat to the world, especially Canada. As a country at the
northern limit to agriculture in the world, it would take very little
cooling to destroy much of our food crops, while a warming would only
require that we adopt farming techniques practiced to the south of us.
Meantime, we need to continue research into this, the most complex field
of science ever tackled, and immediately halt wasted expenditures on the
King Canute-like task of "stopping climate change."

Forget Warming -
Beware the New Ice Age
The Deniers -- Part

Lawrence Solomon, Financial Post
Published: Friday, June 15, 2007
In the 1970s, leading scientists claimed that the world was threatened
by an era of global cooling.
Based on what we've learned this decade, says George Kukla, those
scientists - and he was among them -- had it right. The world is about
to enter another Ice Age.
Dr. Kukla, in 1972 a member of the Czechoslovakian Academy of Sciences
and a pioneer in the field of astronomical forcing, became a central
figure in convincing the United States government to take the dangers of
climate change seriously. In January of that year, he and another
geologist, Robert Matthews of Brown University, convened what would
become a historic conference of top European and American investigators
in Providence, R.I. The working conference's theme: "The Present
Interglacial: How and When will it End?"
Later that year, Drs. Kukla and Matthews highlighted the dangers of
global cooling in Science magazine and, because of the urgency of the
matter, in December they also alerted President Richard Nixon in a joint
letter. The conference had reached a consensus, their letter stated,
that "a global deterioration of climate, by order of magnitude larger
than any hitherto experienced by civilized mankind, is a very real
possibility and indeed may be due very soon. The cooling has natural
cause and falls within the rank of processes which produced the last ice
age."
The White House reacted swiftly to the letter, which described
"substantially lowered food production" and "extreme weather anomalies,"
such as killer frosts and floods, as well as a warning that the Soviet
Union might already be in the lead in preparing for the climate
disturbances to come. By February 1973, the State Department had
established a Panel on the Present Interglacial, which advised Drs.
Kukla and Matthews that it "was seized of the matter."
Soon, numerous other government agencies were drawn in -- the issue was
seen to be of paramount importance -- and by 1974, a federal government
report, A United States Climate Program, cited evidence of the gathering
storm, including:
"A killing winter freeze, followed by a severe summer heat wave in the
United States.
"Drought in the Soviet Union producing a 12% shortfall in their grain
production in 1972, forcing the country to purchase grain abroad, which
in turn reduced world grain reserves and helped drive up food prices.
"Collapse of the Peruvian anchovy harvest in late 1972 and early 1973,
related to fluctuations in the Pacific Ocean currents and atmospheric
circulation, impacted world supplies of fertilizer, the soybean market
and prices of other protein feed stocks.
"The anomalously low precipitation in the U.S. Pacific Northwest during
the winter of 1972-73 depleted water-reservoir storage by an amount
equivalent to an amount of water required to generate more than 7% of
the electric energy for the region."
By 1975, the first of numerous bills, such as the "National Climate
Program Act of 1975," was introduced to establish a co-ordinated
national program of climate research, monitoring, prediction and
contingency-planning analysis. Much congressional testimony spoke of the
inadequacy of climate research and the need for preparedness. Meanwhile,
the failure of the Soviet Union's wheat crop (and a subsequent
high-profile U.S. wheat deal), the severe winter of 1976-77 and El
Nino's influence on climate became dinner-table talk, heightening the
government's desire to predict the climate. In September, 1979,
President Jimmy Carter signed the National Climate Program Act into law,
in aid of predicting future climate and combating global cooling. That
act has now been enlisted in the effort to counter global warming.
Many today speak with derision of the 1970s global-cooling scare, seeing
it as a cautionary false alarm. Others see it as an embarrassment --
Newsweek magazine, which published a 1975 article entitled "The Cooling
World," even corrected the record with a 2006 follow-up to its 1975
article arguing that scientists now have it right.
Dr. Kukla sees it -- and the 1975 Newsweek article -- differently.
Although the magazine article indicated that the cooling trend would be
continuous, scientists knew otherwise. "None of us expected
uninterrupted continuation of the trend," he states. Moreover, thanks to
new evidence that Dr. Kukla only recently published, he now knows that
global warming always precedes an ice age. That makes the current period
of global warming a mere blip that constitutes additional indication of
the ice age to come.
To Dr. Kukla, the fundamental issue here could not be more clear. For
millions of years, the geologic record shows, Earth has experienced an
ongoing cycle of ice ages, each typically lasting about 100,000 years,
and each punctuated by briefer, warmer periods called interglacials,
such as the one we are now in. This ongoing cycle closely matches cyclic
variations in Earth's orbit around the sun.
"I feel we're on pretty solid ground in interpreting orbit around the
sun as the primary driving force behind ice-age glaciation. The
relationship is just too clear and consistent to allow reasonable
doubt," Dr. Kukla said. "It's either that, or climate drives orbit, and
that just doesn't make sense."

NASA Chief Silenced
The Deniers -- Part

Published: Friday, June 08, 2007
Michael Griffin aired his doubts
about climate-change politics on National Public Radio. Under a barrage
of criticism, he recanted.
The head of NASA -- the National
Aeronautical and Space Association--is "an idiot" and "in denial." He is
also "surprisingly naive" and "a fool." With his judgment and competence
so lacking, demands abound for his resignation as head of the largest
and most accomplished science agency in the world.
Those comments and others in the past week have come from scientists
shocked to learn that NASA chief Michael Griffin thinks differently than
they about global warming. Among the most shocked is one of Dr.
Griffin's own employees, James Hansen, a top climate scientist who
"almost fell off my chair" when he learned that his research hadn't
convinced his boss. "It's an incredibly arrogant and ignorant
statement," he told ABC News, referring to an interview of Dr. Griffin
on National Public Radio. "It indicates a complete ignorance of
understanding the implications of climate change."
Some might think Dr. Griffin is entitled to think for himself. Apart
from his PhD in aerospace engineering, he holds five masters degrees, he
is a member of the National Academy of Engineering and the International
Academy of Astronautics, he manages a US$1.1-billion climate-research
budget and was unanimously confirmed to head NASA by the United States
Senate.
But no. He is either "totally clueless" or "a deep anti-global warming
ideologue," concludes Jerry Mahlman, a scientist at the National Center
for Atmospheric Research, in a statement similar to many.
Dr. Griffin's radio interview drew this storm of controversy after he
was asked about the seriousness of global warming. He replied by saying,
"I am not sure that it is fair to say that it is a problem we must
wrestle with. To assume that it is a problem is to assume that the state
of Earth's climate today is the optimal climate, the best climate that
we could have or ever have had, and that we need to take steps to make
sure that it doesn't change."
Dr. Griffin doesn't dispute that the Earth has been warming. He does
dispute that we can -- or even should -- do anything about it. "First of
all, I don't think it's within the power of human beings to assure that
the climate does not change, as millions of years of history have shown.
And second of all, I guess I would ask which human beings, where and
when, are to be accorded the privilege of deciding that this particular
climate that we have right here today, right now, is the best climate
for all other human beings. I'm, I think that's a rather arrogant
position for people to take."
Dr. Griffin's interview was prompted by criticisms from environmental
journalist Greg Easterbrook, who charged that Dr. Griffin is wasting
NASA's time and money on misguided space exploration projects, such as a
manned mission to Mars and the establishment of a permanent base on
the moon. Instead, Easterbrook argued, Dr. Griffin should be exercising
his right to free speech, coming out against misguided NASA policies and
spending more on legitimate priorities, such as greater global-warming
research.
The Easterbrook charge led National Public Radio to ask Dr. Griffin why
he wasn't "battling [global warming] as an army might battle an enemy."
Dr. Griffin's response: "Nowhere in NASA's authorization, which of
course governs what we do, is there anything at all telling us that we
should take actions to effect climate change in either -- in one way or
another.... NASA is not an agency chartered to, quote, 'battle climate
change.' "
More howls from critics, who believe Dr. Griffin should be using his
discretion to skew NASA's mission away from its core purpose -- and away
from his fiduciary responsibilities to his organization -- and toward
the service of fighting climate change.
To which Dr. Griffin responds, not unreasonably, "The question is, in a
democratic society, who gets to choose. Unfortunately for Greg, it's not
him."
Unfortunately for society, Greg Easterbrook happened to be wrong in
another claim: that Dr. Griffin hadn't lost his right to speak out. For
all intents and purposes, he has. Within days of the uproar, Dr. Griffin
decided that he should not have discussed "an issue which has become far
more political than technical." In an apology to his staff, he said, "I
feel badly that I caused this amount of controversy over something like
this," adding that, "it would have been well for me to have stayed out
of it."
Dr. Griffin is now one more scientist who will not dispute the existence
of a "scientific consensus on global warming."

They Call This a

Published: Saturday, June 02, 2007
"Only an insignificant fraction of scientists deny the global warming
crisis. The time for debate is over. The science is settled."
So said Al Gore ... in 1992. Amazingly, he made his claims despite much
evidence of their falsity. A Gallup poll at the time reported that 53%
of scientists actively involved in global climate research did not
believe global warming had occurred; 30% weren't sure; and only 17%
believed global warming had begun. Even a Greenpeace poll showed 47% of
climatologists didn't think a runaway greenhouse effect was imminent;
only 36% thought it possible and a mere 13% thought it probable.
Today, Al Gore is making the same claims of a scientific consensus, as
do the United Nation's Intergovernmental Panel on Climate Change and
hundreds of government agencies and environmental groups around the
world. But the claims of a scientific consensus remain unsubstantiated.
They have only become louder and more frequent.
More than six months ago, I began writing this series, The Deniers. When
I began, I accepted the prevailing view that scientists overwhelmingly
believe that climate change threatens the planet. I doubted only claims
that the dissenters were either kooks on the margins of science or
sell-outs in the pockets of the oil companies.
My series set out to profile the dissenters -- those who deny that the
science is settled on climate change -- and to have their views heard.
To demonstrate that dissent is credible, I chose high-ranking scientists
at the world's premier scientific establishments. I considered stopping
after writing six profiles, thinking I had made my point, but continued
the series due to feedback from readers. I next planned to stop writing
after 10 profiles, then 12, but the feedback increased. Now, after
profiling more than 20 deniers, I do not know when I will stop -- the
list of distinguished scientists who question the IPCC grows daily, as
does the number of emails I receive, many from scientists who express
gratitude for my series.
Somewhere along the way, I stopped believing that a scientific consensus
exists on climate change. Certainly there is no consensus at the very
top echelons of scientists -- the ranks from which I have been drawing
my subjects -- and certainly there is no consensus among astrophysicists
and other solar scientists, several of whom I have profiled. If
anything, the majority view among these subsets of the scientific
community may run in the opposite direction. Not only do most of my
interviewees either discount or disparage the conventional wisdom as
represented by the IPCC, many say their peers generally consider it to
have little or no credibility. In one case, a top scientist told me
that, to his knowledge, no respected scientist in his field accepts the
IPCC position.
What of the one claim that we hear over and over again, that 2,000 or
2,500 of the world's top scientists endorse the IPCC position? I asked
the IPCC for their names, to gauge their views. "The 2,500 or so
scientists you are referring to are reviewers from countries all over
the world," the IPCC Secretariat responded. "The list with their names
and contacts will be attached to future IPCC publications, which will
hopefully be on-line in the second half of 2007."
An IPCC reviewer does not assess the IPCC's comprehensive findings. He
might only review one small part of one study that later becomes one
small input to the published IPCC report. Far from endorsing the IPCC
reports, some reviewers, offended at what they considered a sham review
process, have demanded that the IPCC remove their names from the list of
reviewers. One even threatened legal action when the IPCC refused.
A great many scientists, without doubt, are four-square in their support
of the IPCC. A great many others are not. A petition organized by the
Oregon Institute of Science and Medicine between 1999 and 2001 claimed
some 17,800 scientists in opposition to the Kyoto Protocol. A more
recent indicator comes from the U.S.-based National Registry of
Environmental Professionals, an accrediting organization whose 12,000
environmental practitioners have standing with U.S. government agencies
such as the Environmental Protection Agency and the Department of
Energy. In a November, 2006, survey of its members, it found that only
59% think human activities are largely responsible for the warming that
has occurred, and only 39% make their priority the curbing of carbon
emissions. And 71% believe the increase in hurricanes is likely natural,
not easily attributed to human activities.
Such diversity of views is also present in the wider scientific
community, as seen in the World Federation of Scientists, an
organization formed during the Cold War to encourage dialogue among
scientists to prevent nuclear catastrophe. The federation, which
encompasses many of the world's most eminent scientists and today
represents more than 10,000 scientists, now focuses on 15 "planetary
emergencies," among them water, soil, food, medicine and biotechnology,
and climatic changes. Within climatic changes, there are eight
priorities, one being "Possible human influences on climate and on
atmospheric composition and chemistry (e.g. increased greenhouse gases
and tropospheric ozone)."
Man-made global warming deserves study, the World Federation of
Scientists believes, but so do other serious climatic concerns. So do 14
other planetary emergencies. That seems about right.

Published: Friday, May 25, 2007
Germany's Hans von Storch, one of the
world's leading climate scientists, believes that climate change is for
real and that humans are responsible. He also believes that we shouldn't
fear climate change, that predictions of doom are "hysterical" when they
aren't "completely idiotic and dubious," and that many of the science
establishment's pronouncements on climate change are bereft of
scientific merit.
"Theories of global warming have left laboratories far behind. Now, they
are the stuff of Hollywood," he wrote in Der Spiegel, in an article that
castigated global warming alarmists for debasing scientific inquiry and
intimidating those who would challenge the conventional wisdom. Michael
Crichton's novel State of Fear has it right in its portrayal of
environmental extremism, Dr. Storch believes.
"Despite some artful fictionalization of the facts, Crichton has
certainly delivered an accurate portrayal of the dynamics of
communication among the scientific community, environmental
organizations, government and civil society.
"Like the protagonists in Crichton's thriller, the general belief is
that in order to keep public attention focused on the issue of 'climate
catastrophe' [it must] be presented 'somewhat more attractively.' "
The "climate catastrophe" is hype, he stated. "In the early 1990s, just
as Germany was being hit by severe windstorms, the German media were
reporting that the storms were becoming more and more severe. Since
then, storms of this magnitude have once again become less common in
Northern Europe, a fact now ignored by the media. They have also ignored
the fact that changes in barometric pressure measured in Stockholm since
the days of Napoleon reveal no systematic change in the frequency and
severity of storms."
The fear of climate change, and the blaming of humans for them, did not
start with global warming and the Kyoto Protocol of the 1990s. This fear
is a feature of human history, and likely part of human nature, he
explained in a 2005 paper entitled: "A History of Human Perceptions of
Anthropogenic Climate Change in the Past 1,000 Years."
In the last half century, global cooling theories arose, with man the
culprit due to industrial pollution. Nuclear weapons testing also
prompted an explosion of theories about the implication on the weather.
In the first half of the 20th century, First World War gunfire was
blamed for wet summers, as was shortwave transatlantic radio
communication. Because of a major warming that took place in large parts
of the world, Monthly Weather Review in 1933 published an unsettling
article entitled: "Is the Climate Changing?"
In the 19th century, European and North American scientists claimed that
the water levels of rivers would fall continuously, leading to fears
that the weather would change and to the laying of blame on both
deforestation and reforestation. Europe's abnormally wet summer of 1816,
meanwhile, was blamed on the lightning rods that had just come into
vogue.
In earlier centuries, such as the 14th, which saw a prolonged wet period
in England, the cause was man's wicked lifestyle, which precipitated
divine retribution. "And nowadays it's those hedonistic wastrels who
pollute the air so that they can look at some pretty fish in the South
Seas," Dr. Storch states, adding that "many scientists see themselves
too much as priests whose job it is to preach moralistic sermons to
people?it would be better if we just presented the facts and scenarios
dispassionately --and then society can decide for itself what it wants
to do to influence climate change."
But scientists don't, and neither do
the governments and quasi-governmental scientific establishments that
now lend their own authority to climate-change myth-making.
Dr. Storch thinks it would be helpful
to learn why humans keep forgetting how wrong we have been in our past
dire forecasts. Until we do, we are doomed to repeat history.

Dr. William Nordhaus discounts climate-change alarmism, but not climate
change itself. He advocates research to better understand its
consequences and to develop more efficient technologies.
If you're type person who sets aside money today university education

afford university tuition your own children, you may think sensible
society invest now major measures stop global warming.
If you're not type – who right mind –
you should forget about Kyoto-like greenhouse-gas reduction targets
crash programs would required meet them. Doing so would not only
economically prudent, would – almost any measure – ethical thing do.
So argues celebrated economist William Nordhaus, author pathbreaking
books studies on global warming, generally considered most authoritative
economist climate change field. verdict on global warming alarmism,
exemplified UK's Stern review, which demanded drastic measures now avert
climate change calamity later: "Completely absurd."
The Stern review, released last year banner headlines, argues cost
inaction greatly exceeds cost action. has been much criticized its
selective use data – Sir Nicholas Stern piles one worst-case scenario
upon another arrive fantastical costs, Dr. Nordhaus among those who note
failing. fact, Sir Nicholas uses Nordhaus source global-warming costs
could present themselves well after year 2100, although Nordhaus
characterized data particularly unreliable.
But series unreliable, worst-case scenarios centuries off, themselves,
still would not warrant extreme greenhousegas prevention investments
Stern review recommends. To make an economic case immediate action, Sir
Nicholas adjusted model have us paying now potential damage could
happening hundreds years now.
Sir Nicholas estimates potential costs climate change so great force on
us "20% cut per-capita consumption, now forever." Yet data showed low
damages climate change next two centuries. To overcome data, he applied
model what economists call "near-zero social discount rate." Doing so
brings forward future expenses – Stern review's case, expenses might
occur 23rd 24th centuries. Stern review then presents us with tab
includes these far-out costs, invoice eye-popping indeed.
But Stern review approach defies logic, Dr. Nordhaus illustrates
demonstrating just where zero social-discount-rate thinking leads.
"Suppose scientists discover wrinkle climatic system will cause damages
equal 0.01% output starting 2200 continuing rate thereafter," he
explains. "How large onetime investment would justified today remove
wrinkle starting after two centuries? answer payment 15% world
consumption today (approximately US$7-trillion) would pass review's
costbenef test. seems completely absurd. bizarre result arises because
value future consumption stream so high with near-zero discounting would
trade off large fraction today's income increase far-future income
stream very tiny fraction."
Moreover, who should asked forgo consumption? hardly seems fair keep
back poor countries, yet, if paid rich countries alone, decline would
far exceed Great Depression.
Some climate-change alarmists argue should invest combating climate
change now an insurance policy against risk future damage. Sounds
prudent, until you consider premium paid.
"Suppose suddenly learn 10% probability wrinkle climatic system reduces
post- 2200 income stream 0.01%," Dr. Nordhaus explains, again illustrate
Stern review's logic. "What insurance premium would justified today
reduce probability zero? With conventional discount rates, would
probably ignore any tiny wrinkle two three centuries ahead. If did
careful calculation using conventional discount rates, would calculate
break-even 0.0002% insurance premium remove year 2200 contingency,
0.0000003% premium year-2400 contingency. Moreover, these dollar
premiums are small whether probability large small.
"With review's near-zero discount rate, offsetting low-probability
wrinkle would worth an insurance premium today almost 2% current income,
$1-trillion. We would pay almost same amount if threshold were crossed
2400 rather than 2200."
Dr. Nordhaus's conclusion about such scares: "We are effect forced make
current decisions about highly uncertain events distant future, even
though these estimates are highly speculative are almost sure refined
over coming decades."
Dr. Nordhaus discounts climate-change alarmism, but not climate change
itself. He advocates research better understand its consequences develop
more efficient technologies. He advocates elimination subsidies
artificially increase greenhouse-gas emissions, other "no-regrets"
measures would benef environment without harming economy. costs climate
change are real, he believes, society should act. But not overreact.

Some Restraint in

The Deniers -- Part

President George Bush meets Pope Benedict in June. Some Vatican
authorities are lobbying the Pope to press the U.S. administration to
act on global warming.
"It's not for me to say what the Pope and President Bush should discuss,
but certainly they will discuss current issues and therefore I imagine
and I hope they will [discuss climate change]," said Cardinal Renato
Martino, president of the Pontifical Council for Justice and Peace, the
Vatican organization charged with developing policy for the environment
and social issues.
Cardinal Martino spoke at the start of "Climate Change and Development,"
a Vatican study seminar two weeks ago designed to "search for solutions
to the phenomenon of global warming." The 80 scientists, politicians,
theologians and bishops in attendance were asked to consider that:
"Global warming may bring about not only the imposition of drastic
corrective means to protect the natural environment, but also a grave
threat that destabilizes the world."
By the seminar's end, the 80 participants had heard dire warnings from
some experts, but they heard much more, too -- that global warming is
natural, the cause of warming being primarily solar and that it can be
beneficial.
During the two-day event, tensions were often high -- the Catholic News
Service, which interviewed participants at the private event, described
how one pastor needed to calm down a distraught participant in the
corridor, and used words like "bitter" and "heated" to set the early
mood at the seminar. No one left the seminar thinking that the science
of global warming is settled. To the dismay of those hoping that the
high-level group would inspire a Church-led climatechange crusade, the
Cardinal, in closing the seminar, urged caution in taking any position
on global warming.
The man most responsible for quelling any potential call to action is
one of the Vatican's own, Antonino Zichichi, a member of the Pontifical
Academy of Sciences. Dr. Zichichi, who made the seminar's most powerful
presentation, set its tone. It amounted to a damning indictment of the
UN's Intergovernmental Panel on Climate Change, the body responsible for
most of the dire warnings that the press reports daily.
Dr. Zichichi demonstrated "that models used by the Intergovernmental
Panel on Climate Change (IPCC) are incoherent and invalid from a
scientific point of view," reported Zenit, a news service that acts as
an extension of the Vatican administration. "On the basis of actual
scientific fact 'it is not possible to exclude the idea that climate
changes can be due to natural causes,' and that it is plausible that
'man is not to blame.' "
Dr. Zichichi has concluded that solar activities are responsible for
most of the global warming that earth has experienced -- he estimates
that man-made causes of global warming account for less than 10% -- and
his conclusions have gravitas: This man is the president of the World
Federation of Scientists, past president of the European Physical
Society, past president of the Italian National Institute for Nuclear
and Subnuclear Physics, and past president of the NATO Science Committee
for Disarmament Technology.
He is also Italy's most renowned scientist, credited with the discovery
of nuclear antimatter, the discovery of the "time-like" electromagnetic
structure of the proton, the discovery of the effective energy in the
forces which act between quarks and gluons, and the proof that, despite
its complex structure, it is impossible to break the proton.
"There is a need to do more work, with a lot more rigour, to better the
models being used," he argued in a 60-page written paper that
accompanied his speech to the seminar.
The Vatican seminar was extraordinary, participants agree: Faith and
reason met in inspired discussion and debate about global warming, and
despite the occasional heat, came away the wiser for it. How different
from the debate on climate change conducted by environmental groups, or,
for that matter, the Parliament of Canada, the U.S. Congress or the
German Reichstag, where global warming discussions rely on faith alone,
and result in one-sided dogma.

The Ice-core Man
The Deniers -- Part

Published: Friday, May 04, 2007
Once upon a time, and for millennia before then, carbon dioxide levels
in the atmosphere were low and stable. Then came the industrial
revolution and CO2 levels began to rise. The more man industrialized,
the more that CO2 -- and the temperature -- rose. In the last half
century, with industrialization at unprecedented levels, CO2 reached
levels unprecedented in the human history. This is the story of global
warming.
This story is a fable, says Zbigniew Jaworowski, past chairman of the
United Nations Scientific Committee on the Effects of Atomic Radiation,
a participant or chairman of some 20 Advisory Groups of the
International Atomic Energy Agency and the United Nations Environmental
Program, and current chair of the Scientific Committee of the Central
Laboratory for Radiological Protection in Warsaw.
Dr. Jaworowski agrees that CO2 levels rose in the last half century.
Starting in 1958, direct, real-time measurements of CO2 have been
systematically taken at a state-of-the-art measuring station in Hawaii.
These measurements, considered the world's most reliable, are a good
basis for science by bodies like the UN's Intergovernmental Panel on
Climate Change, the agency that is co-ordinating the worldwide effort to
stop global warming.
But the UN does not rely on direct real-time measurements for the period
prior to 1958. "The IPCC relies on icecore data -- on air that has been
trapped for hundreds or thousands of years deep below the surface," Dr.
Jaworowski explains. "These ice cores are a foundation of the global
warming hypothesis, but the foundation is groundless -- the IPCC has
based its global-warming hypothesis on arbitrary assumptions and these
assumptions, it is now clear, are false."
Ice, the IPCC believes, precisely preserves the ancient air, allowing
for a precise reconstruction of the ancient atmosphere. For this to be
true, no component of the trapped air can escape from the ice. Neither
can the ice ever become liquid. Neither can the various gases within air
ever combine or separate.
This perfectly closed system, frozen in time, is a fantasy. "Liquid
water is common in polar snow and ice, even at temperatures as low as
-72C," Dr. Jaworowski explains, "and we also know that in cold water,
CO2 is 70 times more soluble than nitrogen and 30 times more soluble
than oxygen, guaranteeing that the proportions of the various gases that
remain in the trapped, ancient air will change. Moreover, under the
extreme pressure that deep ice is subjected to -- 320 bars, or more than
300 times normal atmospheric pressure -- high levels of CO2 get squeezed
out of ancient air."
Because of these various properties in ancient air, one would expect
that, over time, ice cores that started off with high levels of CO2
would become depleted of excess CO2, leaving a fairly uniform base level
of CO2 behind. In fact, this is exactly what the ice cores show.
"According to the ice-core samples, CO2 levels vary little over time,"
Dr. Jaworowski sates. "The ice core data from the Taylor Dome in
Antarctica shows almost no change in the level of atmospheric CO2 over
the last 7,000 to 8,000 years -- it varied between 260 parts per million
and 264 parts per million.
"Yet other indicators of past CO2 levels, such as fossil leaf stomata,
show that CO2 levels over the past 7,000 to 8,000 years varied by more
than 50 parts per million, between 270 and 326 parts per million. We
also know that there have been great fluctuations in temperature over
that time period -- the Little Age just 500 years ago, for example. If
the icecore record was reliable, and CO2 levels reflected temperatures,
why wouldn't the ice-core data have shown CO2 levels to fall during the
Little Ice Age? "
Dr. Jaworowski has devoted much of his professional life to the study of
the composition of the atmosphere, as part of his work to understand the
consequences of radioactive fallout from nuclear-weapons testing and
nuclear reactor accidents. After taking numerous ice samples over the
course of a dozen field trips to glaciers in six continents, and
studying how contaminants travel through ice over time, he came to
realize how fraught with error ice-core samples were in reconstructing
the atmosphere. The Chernobyl accident, whose contaminants he studied in
the 1990s in a Scandinavian glacier, provided the most illumination.
"This ice contained extremely high radioactivity of cesium-137 from the
Chernobyl fallout, more than a thousand times higher than that found in
any glacier from nuclear-weapons fallout, and more than 100 times higher
than found elsewhere from the Chernobyl fallout," he explained. "This
unique contamination of glacier ice revealed how particulate
contaminants migrated, and also made sense of other discoveries I made
during my other glacier expeditions. It convinced me that ice is not a
closed system, suitable for an exact reconstruction of the composition
of the past atmosphere."
Because of the high importance of this realization, in 1994 Dr.
Jaworowski, together with a team from the Norwegian Institute for Energy
Technics, proposed a research project on the reliability of trace-gas
determinations in the polar ice. The prospective sponsors of the
research refused to fund it, claiming the research would be "immoral" if
it served to undermine the foundations of climate research.
The refusal did not come as a surprise. Several years earlier, in a
peer-reviewed article published by the Norwegian Polar Institute, Dr.
Jaworowski criticized the methods by which CO2 levels were ascertained
from ice cores, and cast doubt on the global-warming hypothesis. The
institute's director, while agreeing to publish his article, also warned
Dr. Jaworowski that "this is not the way one gets research projects."
Once published, the institute came under fire, especially since the
report soon sold out and was reprinted. Said one prominent critic, "this
paper puts the Norsk Polarinstitutt in disrepute." Although none of the
critics faulted Dr. Jaworowski's science, the institute nevertheless
fired him to maintain its access to funding.
Is there an alternative to ice-core samples, which are but proxies from
which assumptions about the historical composition of the atmosphere can
be made? "Yes, there are several other proxies, and they lead to
different findings about CO2," Dr. Jaworowski states. "But we don't need
to rely on proxies at all.
"Scientists from numerous disciplines have been examining CO2 since the
beginning of the 19th century, and they have left behind a record of
tens of thousands of direct, real-time measurements. These measurements
tell a far different story about CO2 -- they demonstrate, for example,
that CO2 concentrations in the atmosphere have fluctuated greatly, and
that several times in the past 200 years CO2 concentrations have
exceeded today's levels.
"The IPCC rejects these direct measurements, some taken by Nobel Prize
winners. They prefer the view of CO2 as seen through ice."

Gore's Guru

In the history of the global-warming movement, no scientist is more
revered than Roger Revelle of Scripps Institution of Oceanography,
Harvard University and University of California San Diego. He was the
co-author of the seminal 1957 paper that demonstrated that fossil fuels
had increased carbon-dioxide levels in the air. Under his leadership,
the President's Science Advisory Committee Panel on Environmental
Pollution in 1965 published the first authoritative U.S. government
report in which carbon dioxide from fossil fuels was officially
recognized as a potential global problem. He was the author of the
influential 1982 Scientific American article that elevated global
warming on to the public agenda. For being "the grandfather of the
greenhouse effect," as he put it, he was awarded the National Medal of
Science by the first President Bush.
Roger Revelle's most consequential act, however, may have come in his
role as a teacher, during the 1960s at Harvard. Dr. Revelle inspired a
young student named Al Gore.
Dr. Revelle would change Gore's life, particularly since the
climate-change field had become cutting edge, with Dr. Revelle adding to
the excitement by giving his students advance notice of the fruits of
his research.
"It felt like such a privilege to be able to hear about the readouts
from some of those measurements in a group of no more than a dozen
undergraduates," Gore later explained. "Here was this teacher presenting
something not years old but fresh out of the lab, with profound
implications for our future!"
Calling him "a wonderful, visionary professor" who was "one of the first
people in the academic community to sound the alarm on global warming,"
Gore thought of Dr. Revelle as his mentor and referred to him
frequently, relaying his experiences as a student in his book Earth in
the Balance, published in 1992. Gore's warmth for Dr. Revelle cooled,
however, when it became clear that he had misunderstood his former
professor: Although Dr. Revelle recognized potential harm from global
warming, he also saw potential benefits and was by no means alarmed, as
seen in this 1984 interview in Omni magazine: Omni: A problem that has
occupied your attention for many years is the increasing levels of CO2
in the atmosphere, which could cause the earth's climate to become
warmer. Is this actually happening? Revelle I estimate that the total
increase [in CO2] over the past hundred years has been about 21%. But
whether the increase will lead to a significant rise in global
temperature, we can't absolutely say. Omni: What will the warming of the
earth mean to us? Revelle There may be lots of effects. Increased CO2 in
the air acts like a fertilizer for plants ... you get more plant growth.
Increasing CO2 levels also affect water transpiration, causing plants to
close their pores and sweat less. That means plants will be able to grow
in drier climates. Omni: Does the increase in CO2 have anything to do
with people saying the weather is getting worse? Revelle People are
always saying the weather's getting worse. Actually, the CO2 increase is
predicted to temper weather extremes ... .
While Gore in the late 1980s was becoming a prominent politician, loudly
warning of globalwarming dangers, Dr. Revelle was quietly warning
against taking any drastic action.
In a July 14, 1988, letter to Congressman Jim Bates, he wrote that:
"Most scientists familiar with the subject are not yet willing to bet
that the climate this year is the result of 'greenhouse warming.' As you
very well know, climate is highly variable from year to year, and the
causes of these variations are not at all well understood. My own
personal belief is that we should wait another 10 or 20 years to really
be convinced that the greenhouse is going to be important for human
beings, in both positive and negative ways." A few days later, he sent a
similar letter to Senator Tim Wirth, cautioning "... we should be
careful not to arouse too much alarm until the rate and amount of
warming becomes clearer."
Then in 1991, Dr. Revelle wrote an article for Cosmos, a scientific
journal, with two illustrious colleagues, Chauncey Starr, founding
director of the Electric Power Research Institute and Fred Singer, the
first director of the U.S. Weather Satellite. Entitled "What to do about
greenhouse warming: Look before you leap," the article argued that
decades of research could be required for the consequences of increased
carbon dioxide to be understood, and laid out the harm that could come
of acting recklessly: "Drastic, precipitous and, especially, unilateral
steps to delay the putative greenhouse impacts can cost jobs and
prosperity and increase the human costs of global poverty, without being
effective. Stringent controls enacted now would be economically
devastating, particularly for developing countries for whom reduced
energy consumption would mean slower rates of economic growth without
being able to delay greatly the growth of greenhouse gases in the
atmosphere. Yale economist William Nordhaus, one of the few who have
been trying to deal quantitatively with the economics of the greenhouse
effect, has pointed out that '... those who argue for strong measures to
slow greenhouse warming have reached their conclusion without any
discernible analysis of the costs and benefits ... . ' It would be
prudent to complete the ongoing and recently expanded research so that
we will know what we are doing before we act. 'Look before you leap' may
still be good advice."
Three months after the Cosmos article appeared, Dr. Revelle died of a
heart attack. One year later, with Al Gore running for vice-president in
the 1992 presidential election, the inconsistency between Gore's
pronouncements -- he claimed that the "science was settled" then, too --
and those of his mentor became national news. Gore responded with a
withering attack, leading to claims that Dr. Revelle had become senile
before his death, that Dr. Singer had duped Dr. Revelle into
co-authoring the article, and that Dr. Singer had listed Dr. Revelle as
a co-author over his objections. The sordid accusations ended in a
defamation suit and an abject public apology in 1994 from Gore's
academic hit man, a prominent Harvard scientist, who revealed his
unsavory role and that of Gore in the fabrications against Dr. Singer
and Dr. Revelle.
That was then. Would Dr. Revelle, if he were still alive, believe that
global warming now demands urgent action? We can never know. We do know,
however, that Dr. Revelle had no time for the alarmist views of Al Gore
in the 1980s. We also know that those whose views Dr. Revelle respected
continue to caution us against precipitous action: Dr. Revelle's
colleague and friend, Fred Singer, is among the most prominent of Al
Gore's critics, and economist William Nordhaus, generally considered the
leading expert in the field, continue to warn of the economic danger of
climate alarmism.
We also know that the science is still not settled, and that in the
years since Dr. Revelle's death, new research from many of the world's
most respected scientists bears out the cautions that Dr. Revelle
bequeathed us.

Published: Friday, April 13, 2007
Of all the scientists who are labelled "deniers" because they don't
support the orthodoxy of the United Nations Intergovernmental Panel on
Climate Change, none comes in for more vilification than Eigil Friis-Christensen.
For understandable reasons.
Dr. Friis-Christensen questions the very premise that man-made
activities explain most of the global warming that we see, and through
his work he has convinced much of an entire scientific discipline to
explore his line of inquiry. With his 1991 paper in Science, showing a
startling correlation between global warming and the activities of the
sun, Dr. Friis-Christensen unleashed a wave of related research by solar
scientists seeking to learn the mechanisms through which solar activity
may influence climate on Earth. Thanks largely to his early efforts, and
ongoing efforts, too, a growing proportion of the world's solar
scientists no longer place man at the centre of the climate-change
universe.
Dr. Friis-Christensen's interest in climate change predates the Kyoto
Treaty of 1995, it predates the Rio Conference in 1992 that led to
Kyoto, it even predates the first report in 1990 of the IPCC, the body
spearheading the vast majority of the climate-change research now
underway.
"My interest dates back to an extreme solar storm that occurred in
August, 1972," he explains. "I was in Greenland, on my first assignment
in my new job as geophysicist at the Danish Meteorological Institute,
setting up a chain of magnetometer stations on the west coast."
Dr. Friis-Christensen remembers lying in his tent and "watching the ink
pens of my recorder going so wild that they nearly tore the paper chart
apart -- we had no digital recording at that time -- and I wondered
whether such big events could also have an influence in the lower
atmosphere, on weather and climate.
"That storm cut off my contact to the outside world for nine days -- all
radio communication was blacked out -- so I had lots of time to reflect
on the enormity of the forces at play."
Dr. Friis-Christensen would soon discover he had a soulmate in his
reflections, his mentor and a division head at the institute, Knud
Lassen, a pioneer in research into the aurora borealis. They followed
developments in the field, even gave lectures on the subject, which was
then topical, although not for the reasons we're familiar with today --
in the mid-1970s, climate scientists feared global cooling.
Yet for both scientists, the interest was more a hobby than a formal
area of study -- until 1989, when Dr. Lassen, 68 years old and nearing
retirement, decided to cap his career by pursuing the hunch they had
long held. Dr. Friis- Christensen needed no persuading to join him on
his quest. Two years later, their path breaking study was published,
though without fanfare. Global cooling had receded from public memory
and global warming was not yet a hot topic.
That soon changed, with the growing role of the newly created IPCC.
Upon the IPCC's creation, with its mandate to investigate the causes of
climate change, Dr. Friis-Christensen was hopeful of advances in solving
one of the scientific passions of his life. To participate in the IPCC's
quest for answers, he travelled to its January, 1992, meeting in
Guangzhou, China, as part of the Danish delegation. By then, he had
succeeded Dr. Lassen to become head of the institute's geophysics
division.
But to his astonishment, and despite the recent publication of his
Science article, the IPCC refused to consider the sun's influence on
Earth's climate as a topic worthy of investigation. The scientists at
the IPCC had decided that man-made causes and man-made causes alone
deserved their attention. But ignoring the potential role of the sun
didn't make it go away, especially since Dr. Friis-Christensen and other
solar scientists refused to abandon their research.
Then the attacks on Dr. Friis-Christensen's credibility began.
His 1991 study had errors, his detractors stated. His 1995 study only
made it worse, others chimed in. He fabricated data, people whispered. A
recent article in the U.K.'s Guardian newspaper by IPCC partisan George
Monbiot well represents the tenor of the attacks:
"A paper published in the journal Eos in 2004 reveals that the
'agreement' [between temperatures and solar activity that Friis-Christensen's
1991 study found] was the result of 'incorrect handling of the physical
data.' The real data for recent years show the opposite: that the length
of the sunspot cycle has declined, while temperatures have risen. When
this error was exposed, Friis-Christensen and his co-author published a
new paper, purporting to produce similar results.
"But this too turned out to be an artefact of mistakes -- in this case,
in their arithmetic.
"So Friis-Christensen and another author developed yet another means of
demonstrating that the sun is responsible, claiming to have discovered a
remarkable agreement between cosmic radiation influenced by the sun and
global cloud cover ... . But, yet again, the method was exposed as
faulty. They had been using satellite data which did not in fact measure
global cloud cover.
"A paper in the Journal of Atmospheric and Solar-Terrestrial Physics
shows that, when the right data are used, a correlation is not found."
How much of this litany in the Guardian demonstrates actual errors by
Dr. Friis-Christensen? In truth, none of it. Virtually all of the
criticisms of Dr. Friis- Christensen, published and republished
willy-nilly, stem from a lone advisor to the Danish government's
Ministry of the Energy with scant research credentials -- he even admits
that the government hired him largely for his communications skill.
There is no arithmetic error in Dr. Friis-Christensen's studies.
Remarkably, his critics attributed someone else's error to him, and then
kept doggedly repeating their assertion. Neither are there errors in
methodology, although this charge likewise gets repeated without
foundation. Neither should it be surprising that different studies of
different aspects of solar behaviour would yield anomalies. It is
through such exceptions that science proves the rule.
Do the epithets work? With the uninformed, they work a great deal. With
the vast majority of his peers, the attacks more represent irritants,
noise that obfuscates the political debate but not what counts -- the
science. Because of his scientific rigour, Dr. Friis-Christensen has won
a citation from the Journal of Geophysical Research of the American
Geophysical Union for "Excellence in refereeing" and he is sought after
by the world's leading agencies, who have elevated him to the top ranks
of his profession.
He now chairs the Danish Space Consortium, heads a European Space Agency
mission advisory group, and is vice-president of the International
Association of Geomagnetism and Aeronomy. Many of the world's most
prestigious space-related research institutions -- the European
Organization for Nuclear Research in Geneva, the Max Planck Institute
for Solar System Research in Germany, and the Pulkovo Astronomical
Observatory in Russia among them --are now building on the work that Dr.
Friis-Christensen set in train.
Bit by bit, they are putting the pieces of the climate puzzle together,
slowly learning more and more about the amazingly complex relationships
among solar and cosmic forces, on the one hand, and the array of forces
on Earth.
Where this slow, methodical brand of solar science will ultimately lead,
no one can yet say. Such uncertainty does not characterize the brand of
climate science practiced by the IPCC.

Fighting Climate
'Fluff'
The Deniers -- Part
XVIII
Lawrence Solomon, Financial Post

Published: Thursday, April 05, 2007
Physicist Freeman Dyson knows from long experience that models
containing numerous fudge factors are worthless. As a
mathematician and physicist, Freeman Dyson is known for the unification
of three versions of quantum electrodynamics, for his work on the Orion
Project, which proposed space flight using nuclear pulse propulsion, and
for developing the TRIGA, a small, inherently safe nuclear reactor used
by hospitals and universities worldwide for the
production of isotopes.
As a theoretician, he is known for the Dyson sphere (an inspiration for
science fiction such as Star Trek, as well as scientific works), the
Dyson transform (which led to the discovery that every even integer is a
sum of at most six primes) and the Dyson tree (a genetically engineered
plant capable of growing on a comet). In his book The Sun, the Genome,
and the Internet, he proposed engineering "trees that convert sunlight
to liquid fuel and deliver the fuel directly ? to underground
pipelines."
As an activist and visionary, he is known for his concern for global
poverty, for his
promotion of international co-operation and for his work in furtherance
of nuclear
disarmament. He is a member of the board of sponsors of the Bulletin of
the Atomic Scientists, and the subject of numerous writings by
environmental pioneers, such as Stewart Brand.
And this Renaissance Man, who has been prescient in many spheres, among
them space travel and genetic diversity, who has written nine
provocative books of his own and inspired dozens by others, is today
known, too, as a scientific heretic, chiefly for disagreeing with the
conventional wisdom on global warming. Or, as he puts it, "all the fluff
about global warming."
The "fluff," Prof. Dyson explains, comes from climate-change models that
predict all manner of catastrophe. The models count for naught as
predictive tools.
"I have studied their climate models and know what they can do," Prof.
Dyson says. "The models solve the equations of fluid dynamics and do a
very good job of describing the fluid motions of the atmosphere and the
oceans. They do a very poor job of describing the clouds, the dust, the
chemistry and the biology of fields, farms and forests. They do not
begin to describe the real world that we live in."
Prof. Dyson explains that the many components of climate models are
divorced from first principles and are "parameterized" -- incorporated
by reference to their measured effects.
"They are full of fudge factors that are fitted to the existing climate,
so the models
more or less agree with the observed data. But there is no reason to
believe that the same fudge factors would give the right behaviour in a
world with different chemistry, for example in a world with increased
CO2 in the atmosphere," he states.
Prof. Dyson learned about the pitfalls of modelling early in his career,
in 1953, and
from good authority: physicist Enrico Fermi, who had built the first
nuclear reactor in 1942. The young Prof. Dyson and his team of graduate
students and post-docs had proudly developed what seemed like a
remarkably reliable model of subatomic behaviour that corresponded with
Fermi's actual measurements. To Prof. Dyson's dismay, Fermi quickly
dismissed his model.
"In desperation, I asked Fermi whether he was not impressed by the
agreement between our calculated numbers and his measured numbers. He
replied, 'How many arbitrary parameters did you use for your
calculations?' I thought for a moment about our cut-off procedures and
said, 'Four.' He said, 'I remember my friend Johnny von Neumann [the
co-creator of game theory] used to say, with four parameters I can fit
an elephant, and with five I can make him wiggle his trunk.' With that,
the conversation was over."
Prof. Dyson soon abandoned this line of inquiry. Only years later, after
Fermi's death, did new developments in science confirm that the
impressive agreement between Prof. Dyson's model and Fermi's
measurements was bogus, and that Prof. Dyson and his students had been
spared years of grief by Fermi's wise dismissal of his speculative
model. Although it seemed elegant, it was no foundation upon which to
base sound science.
Unlike many scientists today, who seek the comfort of consensus as
opposed to thinking for themselves, Prof. Dyson has always been happy to
be in the minority. He tells the story of his stint as an analyst during
the Second World War in the U.K.'s Bomber Command, when he proposed
ripping out two gun turrets from R.A.F. Lancaster bombers. Without the
turrets, they could fly 50 miles per hour faster, be much more
manoeuvrable and cut the U.K.'s catastrophic losses to German fighters.
Those at the top preferred to delude themselves: "To push the idea of
ripping out gun turrets, against the official mythology of the gallant
gunner defending his crewmates ? was not the kind of suggestion the
commander in chief liked to hear."
Today's official mythology involves global warming, in a societal
mobilization of
another kind. The allure of the conventional wisdom has not changed.
"Here I am opposing the holy brotherhood of twilight model experts and
the crowd of deluded citizens that believe the numbers predicted by
their models." A heretic he remains, and, as history has shown, much
more often right than not.

Little Ice Age Is
Still with Us
The Deniers -- Part
XVII
Lawrence Solomon, Financial Post
-- Canada
Published: Friday, March 30, 2007
The Earth slowly but surely warmed over the course of the 20th century,
global temperatures increasing by about half a degree Celsius. The
evidence for this global warming comes from ice core data from the
Arctic island of Severnaya Zemlya, published just last year.
The Earth slowly but surely warmed over the course of the 19th century,
too, global temperatures again increasing by about half a degree
Celsius. The evidence for this global warming comes from the same ice
core data.
The Earth slowly but surely warmed over the course of the 18th century,
too, global temperatures increasing by about a half a degree Celsius.
The evidence for the global warming that occurred during the 18th
century comes from multiple sources, all well recognized.
The Earth slowly but surely warmed over the course of the latter part of
the 17th century as well, global temperatures increasing at the rate of
about a half a degree Celsius per century, according to one of those
multiple sources, the only one that extends that far back.
Throughout these centuries, which followed the depths of the Little Ice
Age, the rate of global warming has been fairly consistent. "There is
clearly a linear increase of temperature from about 1800 based on last
year's ice-core data," states geophysicist Syun-Ichi Akasofu of the
University of Alaska. "Roughly the same linear change in temperatures
extends back to the earliest recordings, going back to about 1660, even
before the Industrial Revolution."
Dr. Akasofu, the founder of the International Arctic Research Center and
a giant in Arctic research since his discovery in 1964 of the origin of
storms in the aurora borealis, postulates a startlingly straightforward
explanation of the warming Earth has seen in the 20th century. The long
slow climb out of the Little Ice Age, he states, is typically thought to
have ended in 1900. Chances are good that it didn't. "The Earth may
still be recovering from the Little Ice Age," he says, pointing to the
consistent rate of warming over the centuries.
Although Dr. Akasofu thinks a continuation of the Little Ice Age can
explain the 20th-century warming, he believes other explanations may
also be valid. Any explanation, however, would point to a natural
process, and not manmade CO2. The evidence for this lies in the Arctic,
which magnifies temperature fluctuations seen at lower latitudes,
highlighting temperature changes that might otherwise seem unremarkable.
Arctic data, for example, shows a very large rise and then fall in
temperature between 1910 and 1975, while the global average data shows
this fluctuation as more a minor blip, peaking at 1940. A second
temperature fluctuation involves a rise after 1975.
Because the pre-1940 increase in temperature happened without much CO2,
and the 1940-75 temperature decline happened after CO2 emissions began
in earnest, "the large fluctuation between 1910 and 1975 can be
considered to be a natural change. Contrary to the statement by the UN's
Intergovernmental Panel on Climate Change in its 2007 Report, it is not
possible to say with any confidence that the rise after 1975 is mostly
caused by the greenhouse effect."
Ironically, the IPCC's own climate-change models also point to carbon
dioxide's irrelevance in climate change. The Earth's warming is not
uniform: Different geographic regions are warming at different rates,
while others are actually cooling. Dr. Akasofu asked the IPCC's Arctic
group to apply its global climate models to "hindcast" the geographic
distribution of the temperature change during the last half of the last
century. ("Hindcasting" asks a model to produce results that match the
known observations of the past --a model that can do this helps
establish its ability to predict future conditions.)
To his surprise, the model's results showed dramatically different
temperatures than those obtained from actual readings, with no apparent
relationship between the two. Initially, Dr. Akasofu thought the problem
lay in the model. "However, this possibility is inconceivable, because
the increase of CO2 measured in the past is correctly used in the
hindcasting, and everything we know is included in the computation. It
took a week or so for another possibility to dawn on us: If the warming
and cooling is not caused by the greenhouse effect, the models will not
show CO2-related warming and cooling."
To examine that possibility, Dr. Akasofu checked to see if the magnified
warming in the continental Arctic was still increasing, in line with the
ever-increasing amounts of CO2 entering the atmosphere. To his surprise,
the continental Arctic had stopped its magnified warming, and was now
warming only at the same rate as the rest of the world. The upshot: The
IPCC models tend to confirm that: "Much of the prominent continental
Arctic warming during the last half of the last century is due to
natural change."

Bitten by the IPCC
The
Deniers -- Part XVI
Lawrence Solomon, Financial Post –

Published: Friday, March 23, 2007
The UN's
Intergovernmental Panel on Climate Change is very particular about the
scientists it selects to investigate the health consequences of global
warming. Those the likes of Paul Reiter needn't apply.
Prof. Reiter heads
the Insects and Infectious Disease Unit at the Pasteur Institute, famed
for its founding by Louis Pasteur in 1887 and the eight Nobel Prizes
that its later scientists received. Prior to joining the Pasteur
Institute, Prof. Reiter directed the entomology section at the Dengue
Branch of the Centers for Disease Control, the path-breaking U.S.
government agency. Prof. Reiter is also known for his work as an officer
of the Harvard School of Public Health, his membership on the World
Health Organization's Expert Advisory Committee on Vector Biology and
Control, and, among administrative positions, his role as lead author of
the Health Section of the U.S. National Assessment of the Potential
Consequences of Climate Variability and Change.
Because of his
history of excellence in researching diseases transmitted by mosquitoes
and other insects, the U.S. State Department in 2001, upon the
recommendation of its own health authorities, nominated Prof. Reiter to
be a lead author of the IPCC's next health chapter. Global warming was
increasing the habitats for mosquitoes, many feared, putting hundreds of
millions of people in the tropics at risk of contracting malaria and
dengue, and raising the spectre that these diseases would spread around
the world. Prof. Reiter, in the view of U.S. health experts, was
particularly well placed to address this research.
The IPCC selected
two other candidates, more suitable in filling the role required of
them. At the time of their selection, neither was distinguished by
having published peer-reviewed articles dealing with mosquito-born
disease. Both were distinguished by their conviction about the dangers
to human health of climate change.
Prof. Reiter was
not entirely surprised that the IPCC passed him over -- he has been a
critic of the science it has disseminated. And neither was he surprised
at the IPCC's failure to select scientists specializing in
mosquito-borne diseases, despite the outsized role of malaria and dengue
in previous IPCC reports. The IPCC faced an impossible task in finding
such an expert.
"I know of no major
scientist with any long record in this field who agrees with the
pronouncements of the alarmists at the IPCC," states Prof. Reiter, whose
history in his research field spans three decades and five continents,
and who is well familiar with the scope of work occurring in the
mosquito-borne research community.
"On the contrary,
all of us who work in the field are repeatedly stunned by the IPCC
pronouncements. We protest, but are rarely quoted, and if so, usually as
a codicil to the scary stuff."
In one of the
IPCC's most egregious errors, in its Second Assessment Report chapter on
human population health, it created the scare -- repeated by scientists
with a popular following such as David Suzuki -- that global warming
could lead to 80 million additional cases of malaria per year worldwide.
The IPCC scientists' "glaring ignorance" dumbfounded Prof. Reiter and
his colleagues. For example, the IPCC claimed that malarial mosquitoes
cannot ordinarily survive temperatures below 16C to 18C, not realizing
that many tropical species do and that many temperate species survive
temperatures of --25C. Likewise, IPCC scientists didn't know at what
altitudes mosquitoes can be found.
As Prof. Reiter
testified to a U.K. parliamentary committee in 2005, "The paucity of
information was hardly surprising: Not one of the lead authors had ever
written a research paper on the subject! Moreover, two of the authors,
both physicians, had spent their entire career as environmental
activists. One of these activists has published "professional" articles
as an "expert" on 32 different subjects, ranging from mercury poisoning
to land mines, globalization to allergies and West Nile virus to AIDS.
"Among the
contributing authors there was one professional entomologist, and a
person who had written an obscure article on dengue and El Nino, but
whose principal interest was the effectiveness of motorcycle crash
helmets (plus one paper on the health effects of cellphones)."
How do such people
become numbered among the IPCC's famed "2,500 top scientists" from
around the world? Prof. Reiter, wanting to know, wrote the IPCC with a
series of detailed questions about its decision-making process. It
replied: "The brief answer to your question below is 'governments.' It
is the governments of the world who make up the IPCC, define its remit
and direction. The way in which this is done is defined in the IPCC
Principles and Procedures, which have been agreed by governments." When
Prof. Reiter checked out the "principles and procedures," he found "no
mention of research experience, bibliography, citation statistics or any
other criteria that would define the quality of 'the world's top
scientists.'"
First and foremost,
Prof. Reiter believes, the IPCC is a creature of government that meets
governmental needs and abides by governmental strictures, and does so
without public scrutiny. In contrast, studies conducted under the more
open auspices of the U.S. government's Global Climate Change Research
program, for example, are entirely in the public domain.
Even the
peer-review process -- ordinarily designed to ensure rigorous science --
has mutated to meet IPCC needs. In professional science, the names of
peer reviewers are kept confidential to encourage independent criticism,
free of recrimination, while the deliberations of the authors being
critiqued are made public.
"The IPCC turns
this on its head," Prof. Reiter explains. "The peer reviewers have to
give their names to the authors, but the deliberations of the authors
are strictly confidential." In effect, the science is spun,
disagreements purged, and results predetermined.
"The
Intergovernmental Panel is precisely that -- it is a panel among
governments. Any scientist who participates in this process expecting
the strictures of science to reign must beware, lest he be stung."

Unsettled Science
The
Deniers -- Part XV

Carl Wunsch,
professor of physical oceanography at the Massachusetts Institute of
Technology, has been wronged. In The Great Global Warming Swindle, a
no-holds-barred documentary that aired last week in the United Kingdom
and will soon be coming to TV sets in North America, he was cast as a
partisan in the climate-change debate. That he is not.
He was also cast as
impugning the motives of scientists who employ complex computer models
to predict the climate 50 or 100 years into the future. That he also did
not do. Neither does he subscribe to the theory, championed in the
documentary, that the sun and not carbon dioxide explains climate
change.
Director Martin
Durkin's documentary -- the rival of Al Gore's An Inconvenient Truth for
brash claims, selective presentations of the facts, and disdain for the
opposing side's views -- is destined to raise a storm of controversy in
the climate-change debate, with Dr. Wunsch destined to be uncomfortably
at its centre.
Yet despite the
untoward liberties taken by the documentary producers, there is little
at dispute of substance. Here, in detail, is the documentary's sole
misrepresentation of fact involving Dr. Wunsch.
In a discussion
about the nature of computer models that attempt to predict Earth's
climate, the narrator introduced his views by saying "there is a danger,
according to Prof. Carl Wunsch, that modellers will be less concerned in
producing a forecast that is accurate than one that is interesting."
The narrator, some
might well conclude, is hinting at ill-will on the part of the modellers,
a conclusion buttressed by statements to this effect from other
scientists in the documentary. Dr. Wunsch is understandably upset at
being seen to criticize colleagues whom he didn't intend to criticize,
and to criticize climate modelling, which he views as a necessary
scientific tool.
Yet from what Dr.
Wunsch did say, it is easy to see why Mr. Durkin would think he took
computer-model results with a grain of salt. "The models are so
complicated you can often adjust them in such a way that they do
something very exciting," he said.
Dr. Wunsch may not
have pointed to conscious wrongdoing on the part of scientists, but he
certainly made it abundantly clear that scientists, being human, are
susceptible to human frailties: "You see, it's a problem. If I run a
complicated model and I do something to it like melt a lot of ice into
the ocean and nothing happens, it's not likely to get printed. But if I
run the same model and I adjust it in such a way that something dramatic
happens to the ocean circulation, like the heat transport turns off, it
will be published. People will say, 'This is very exciting.' It will
even get picked up by the media. So there is a bias, there is a very
powerful bias within the media and within the science community itself
toward results which are dramatizable."
This segment of the
documentary, I believe from my interview with Dr. Wunsch, is the only
explicit portrayal of him that could in any way be considered egregious.
The rest of Dr. Wunsch's complaints lie more with optics: He didn't like
to be seen in the company of scientists who are aggressive participants
in the climate-change debate, as if he shared their views, and he didn't
like the in-your-face title of the documentary, with its use of the word
"swindle" and the accusation that the public has been lied to by those
issuing dire warnings of global change.
Yet even here, the
difference between the director and the professor is more style than
substance. There is precious little of a factual nature in the
documentary that Dr. Wunsch would object to.
The big "lie" to
which the documentary refers -- the only lie that it explicitly claims
-- is that the science is settled on global warming. "Campaigners say
the time for debate is over. Any criticism, no matter how scientifically
rigorous, is illegitimate, even worse, dangerous," the narrator states
at the beginning of the documentary, in setting out his theme.
"Everywhere you are told that manmade climate change is proved beyond
doubt. But you are being told lies." The film then establishes that the
science is not settled "beyond doubt" by filming a series of
commentators, among them prominent academics who had been participants
in the United Nations' Intergovernmental Panel on Climate Change.
