ICE-CORE DOUBTS: SKEPTICS NOT SKEPTICAL ENOUGH

Ice-core expert, Prof. Zbigniew Jaworowski [jaworo@clor.waw.pl] writes from Poland below in answer to the following question: "Given the capability of the biosphere to absorb a surplus of CO2 as small as the human contribution, why do most AGW skeptics go along with the assumption that humans are wholly responsible for the rise in atmospheric CO2 in the last 150 years?".

It seems that they did not spend enough time to peruse in-depth the glaciological papers on CO2, and the original papers on the carbon cycle. They rather glanced over the photos, figures, tables, and read mostly abstracts and conclusions, which tell that for the past >500,000 years almost always "atmospheric" CO2 levels were lower than 290 ppmv, even in periods when the surface temperature was higher than now.

The sceptics credulously accepted the glaciologists' claim that the proxy CO2 determinations in the ice cores, are not proxies but rather direct measurements of this gas in the original ancient atmospheric air, trapped in the allegedly closed system of ice, miraculously not changed by brutal drilling procedures, and tens of physical and chemical processes in the ice sheets and in the ice cores, to say nothing of the liquid water present in the cold Antarctic ice.

The peace of mind of sceptics was not disturbed even by a total disappearance of air inclusions in all deep ice cores. They did not notice this, or what?

The carbon cycle models were all founded on an assumption of low pre-industrial CO2 level of 290 ppmv, even before the glaciological support. A component of these models is the buffer factor, in which the assumption of a pre-industrial CO2 level of 290 is the most important parameter. Future historians of science will probably eagerly study this phenomenon of groupthink, common in evironmental research.

In the light of Prof. Beck's recent paper questioning the accuracy of ice-core data, it is interesting that Prof. Jaworowski's long-known skepticism about the same data does not appear to have been dented by recent attempts (in new drilling) to allow for his criticisms. The points he makes do appear to be powerful ones. That the pre-industrial "stability" seen in pre-industrial ice cores might be nothing more than a methodological artifact (akin to Mann's "hockeystick") seems a very strong possibility





A PESKY FINNISH RIVER

The United Nations graph below is one of the longest time series relevant to global temperature trends that is based on actual direct measurements rather than on inferences from proxies.



You can see that there was a warming trend going on long before industrialization -- which did not hit Finland to any significant degree until the 20th century. So the warming is a natural phenomenon, not one caused by industrialization. See also the article immediately below this one for a comment on the generality of the phenomenon.

ALASKAN 'CLIMATE SKEPTIC' QUESTIONS CONVENTIONAL THINKING



Syun-Ichi Akasofu's greatest successes in a career of studying the aurora came when he questioned the conventional ideas about the phenomenon. "I always become suspicious when many scientists agree on some interpretation," he said.

Now in retirement, the 76-year-old former director of both UAF's Geophysical Institute and International Arctic Research Center is digging in on a new idea that runs contrary to popular beliefs-that today's global warming might be more due to the planet's natural recovery from its last cold period than from our pumping of greenhouse gases into the air. Akasofu recently gave a talk at the International Arctic Research Center in which he presented evidence for how the world has warmed in a steady fashion from well before the Industrial Revolution to the current day.

"If you look back far enough, we have a bunch of data that show that warming has gone on from the 1600s with an almost linear increase to the present," Akasofu said. He showed ice core data from the Russian Arctic that shows warming starting from the early 1700s, temperature records from England showing the same trend back to 1660, and ice breakup dates at Tallinn, Estonia, that show a general warming since the year 1500.

Akasofu said scientists who support the manmade greenhouse gas theory disregard information from centuries ago when exploring the issue of global warming. Satellite images of sea ice in the Arctic Ocean have only been available in the satellite era since the 1960s and 1970s. "Young researchers are interested in satellite data, which became available after 1975," he said. "All the papers since (the advent of satellites) show warming. That's what I call 'instant climatology.' I'm trying to tell young scientists, 'You can't study climatology unless you look at a much longer time period.'"

Melting glaciers, permafrost, and other signs of warming might be Earth's natural recovery from a period known as the Little Ice Age, Akasofu said. The Little Ice Age featured several centuries of very cold temperatures. The Thames River and New York Harbor often froze, and Vikings might have abandoned settlements at the time.

Akasofu said there is no data that "most" of the present warming is due to the manmade greenhouse effect, as the members of the Intergovernmental Panel on Climate Change wrote in February. He pointed out that the atmosphere cooled from 1940 to 1975 despite a rapid increase in carbon dioxide emissions during the same period. "Nature changes all the time," he said. "The natural component is there. Until you remove it, you don't know the manmade effect."

Akasofu said he could recall in the 1960s and 1970s when some scientists were talking about an approaching ice age. In the 1980s, global warming became a popular topic. "I think the initial motivation by the IPCC (established in 1988) was good; it was an attempt to promote this particular scientific field," he said. "But so many (scientists) jumped in, and the media is looking for a disaster story, and the whole thing got out of control."

Akasofu said his tendency to go against the flow has been with him since he was a child in Japan. He looked beyond the accepted theory at the time to discover such things as the auroral substorm, the idea that the aurora explodes with activity more than once each night. In his career, he's seen many unconventional ideas become accepted theories. "Although the Anchorage Daily News called me 'Alaska's best-known climate-change skeptic,' I believe I am a critic," he said. "That is the only way science can advance."

Green Fascism just around the corner in Britain

Something disturbing and ominous is happening in Great Britain as the country embarks on an all-out fight against the threat of global warming. Intent on making Britain the world's first "green" economy, the government will soon introduce legislation designed to take SUVs and other "gas guzzling" vehicles off the road. By sharply increasing driving levies, the authorities intend to force car owners into making "more sustainable travel choices, including greater use of public transport, walking and cycling."

At the same time, homeowners will be asked to make their homes "carbon neutral" and required to draw their energy primarily from low or zero carbon sources such as wave, tide, solar or nuclear power. To ensure compliance, the government will send out inspectors to scrutinize everything from how a home is insulated to the kind of appliances it uses. Those who fail to meet the decreed standards will be fined and penalized. Just how serious the government is about enforcement can be sensed from the words of Environment Secretary David Miliband who stated -- while unveiling the program -- that it would be "painful" for home owners to continue to have an "energy inefficient home."

These sentiments were echoed by a group of cabinet ministers who said that complying with the new regulations will necessitate sweeping changes in lifestyle across the board. Everybody in Britain, they concurred, will have to "live, work and travel differently."

It is essential that we see these developments for what they really are: A thinly-veiled attempt by devotees of the state to take over a western society the like of which has not been seen since the Soviet-sponsored revolutions of the late 1940s.

The practical consequence of these plans -- should they succeed -- will be a radical empowerment of the state which will end up with virtually unlimited powers to regulate nearly every facet of life. Everything from the way people travel to the manner in which they furnish and maintain their homes will now be subject to governmental decree and oversight. Those who refuse to comply will be punished -- and severely so -- if the words of Miliband are anything to go by.

This is precisely why the idea of man-made global warming so appeals to those on the political left. Being ideological cousins of erstwhile socialists, they share a desire to expand government regardless of the cause or issue they ostensibly espouse. In global warming they have sensed the perfect opportunity, for if the underlying claim is true and the planet is indeed headed for destruction, then the impending catastrophe can only be averted by united action on a grand scale. And such action can only be taken by a strong state which has been granted a wide range of powers to deal with this life-or-death crisis.

What makes the global warming scenario even more appealing is that the chief perpetrator is none other than the left's perennial villain -- the business establishment. After all, most of the pollutants are emitted into the atmosphere by unscrupulous businesses as a by-product of their relentless pursuit of ever greater profits. Close second on the list of culprits are us the people whose excessive consumption, runaway appetites and outright recklessness further exacerbate the already critical situation.

The way to safeguard our survival, then, is for government to exercise strict control over both business and the masses. This will be done through taxation and regulation, which, admittedly, will have to be severe at times. But no one should object or complain, since it is only to be expected that this extreme emergency calls for extreme measures. Thus the alleged threat of man-made global warming is used as a means of realizing the left's perennial dream of society administered by a powerful state.

Those on the left have sought to affect this state of affairs for many decades, but until now their efforts have met with vigorous resistance throughout much of the Western world. Not surprisingly, given that it is a world built on the ideals of economic and individual freedom and the principle of limited government.

But by invoking the specter of global warming, the left no longer has to fight tooth and nail for every tax increase or additional regulation. Alarmed by apocalyptic predictions, the frightened populations will now voluntarily and even eagerly turn over their money, freedoms and rights. Fearing for our lives, no tax will seem too excessive or regulatory burden too intrusive. After all, no decree or law can seem too extreme if our very survival is at stake. Believing we face an imminent doom, we shall readily submit to a governmentally mandated compact we would never agree to under normal circumstances.

This time there will be no resistance to this revolution as the state refashions almost all existing relations and usurps the rights and powers that properly belong to the private sphere. There will be no fierce street fighting such as accompanied the bloody revolutions of the past. This time around people will give up their freedoms willingly and even with gladness.

Even Karl Marx himself could not be wholly displeased with the state of affairs toward which the global warming alarmism is inexorably inclining: A vastly empowered state exercising tight oversight over virtually every dimension of life. The only departure from Marx's original vision is the means by which this will be achieved. It will not come about as a result of bitter class struggle, but of a crusade by environmental activists to save the planet.

The tremendous efficacy of the global warming frenzy in advancing the left's agenda can be seen in Britain where state zealots are in the process of taking over one of the world's oldest democracies. Above all, no one should make the mistake of assuming that this is the work of environmental extremists who have somehow managed to worm their way into positions of power and influence. Rather it is the inevitable consequence of accepting the claim of man-made global warming. As such, it is a dire warning of what lies in store for all those who receive this left-induced hysteria as unassailable truth.

When similar measures are finally proposed in America -- as they inevitably will be -- we must be prepared to expose and call them for what they really are: A ruse to bring about the socialist dream of an all-powerful state in charge of every aspect of our lives.

WILL BRITAIN AND EUROPE WISE UP ON GLOBAL WARMING?

If you could divide Europe's nations and regions into "red" and "blue" states on the American model, very few would be colored "red" -- Poland, some other East European countries, rural regions across the continent, etc. Most nations would be cheerfully "blue." But all Europe would be ''green.'' Green is the universal sign of conspicuous virtue, of concern for planet, of a new paganism that worships the goddess Gaia and treats the Earth as itself a single living organism.

Anyone who questions this newly fashionable faith is regarded as a dangerous heretic to be cast into the outer darkness. A minister in the British government suggested to the BBC that it should not allow air time to any scientists who doubted ''global warming'' (a minority of scientists but a distinguished group). Other high priests of the creed have called for "Nuremberg trials" of "climate change deniers."

In this ovebearing moral atmosphere politicians are likely to salute any green flag that the environmentalists run up. And, sure enough, in 10 days there has been in succession:

1. A "summit" of European Union leaders that pledged to cut Europe's carbon emissions by 20 percent from their 1990 levels and, if other countries (especially America) follow their example, by 30 percent.

2. The publication in Britain of a Climate Change Bill, supported by all major parties, that would set legally binding targets to cut Britain's carbon emissions by 60 percent by 2050.

3. A proposal by the supposedly free-market Conservative Party to "allow" every citizen one untaxed air flight a year but then to levy heavy taxes on additional flights in order to discourage air travel.

4. Leaks from Whitehall that Finance Minister Gordon Brown will double fuel taxes in Wednesday's budget as another green measure.

All this is likely to be applauded by the voters -- who are swept up in this green tornado quite as much as the media and politicians -- but will they applaud its effects, large and small, when they pinch? Take small effects first. Under the EU summit agreement, the familiar light bulb is to be outlawed in the next few years in favor of a more carbon-neutral one. Unfortunately, the new bulb is several times more expensive than the existing one and it sheds much less light. Those who can afford the (considerable) expense will use more bulbs to illuminate the same space. Poorer people will develop eye problems and push up health costs. Such are the unintended consequences of thoughtless legislation.

What of large matters? The idea underlying the EU proposals and the British climate change bill is that governments will both impose binding limits on the carbon emissions that industries emit and instruct them to use low-carbon fuels such as wind and solar power. In other words, the EU and Britain are embracing a new form of central planning based on energy-use quotas rather than output quotas. But central planning is a synonym for economic inefficiency and waste. These things happen when green daydreams encounter realities or what Al Gore calls inconvenient truths. Here are a few more of them:

* Almost all the European countries have already failed to meet much lower carbon emission targets under Kyoto than the new targets they adopted 10 days ago.

* When Brown increased fuel taxes six years ago in Britain, nationwide blockades by truck drivers almost brought down the government.

* The British economy accounts for only 2 percent of global carbon emissions. If it were to close down entirely, it would have little or no impact on the world's total carbon output -- and even less impact on the willingness of the Indian and Chinese governments to cut back on building power stations that they consider essential to their nation's prosperity but that are now the main drivers of increased carbon usage.

Britain and Europe's governments are committing themselves to systems of carbon rationing bound to run up against strong consumer and voter resistance within a few years for very little practical gain. Why? Europe's green establishment believes that global warming is caused by carbon usage and thus can be solved only by its massive reduction.

But global warming has several possible causes, some of which, such as the activity of the sun, are unrelated to humans.

While we are seeking to understand global warming scientifically, we should adapt to it -- shoring up coasts against erosion, changing the use of agricultural land to suit the changing climate, building dams, developing new technologies. Adaptation would include measures to encourage the use of cleaner fuels, notably nuclear energy. It would be a practical solution to the effects of warming, whatever science eventually established definitively as its cause.

To be sure, adaptation would be expensive. Not nearly so expensive, however, as trying to close down the free market in Europe and to reverse the Industrial Revolution in Asia. But Gaia is a jealous goddess and does not consider costs.

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is generally to promote themselves as wiser and better than everyone else, truth regardless.

Global warming has taken the place of Communism as an absurdity that "liberals" will defend to the death regardless of the evidence showing its folly. Evidence never has mattered to real Leftists
