COULD GLOBAL WARMING MELT ALL ICE ON EARTH?

A comment from Russia

If all ice on the earth melted, the level of the oceans would rise by 64 meters. Many coastal cities would be under water, and so would the Netherlands, a significant part of which lies below sea level. However, the Dutch and the rest of the planet may rest assured: this hypothetical catastrophe could not take place anytime within the next thousand years.

Our institute has prepared an atlas of the world's snow and ice resources, which describes all the ice on the earth and even offers a map of the world without ice. It is, however, a model, not a forecast. Yet there are forecasts warning that if the global warming seen at the end of the 20th century continues for several decades, a lot of ice in the Artic Ocean will melt.

There is, however, a subtle but important qualification: if Artic ice should melt, the sea level will not change because the volume of water created by melting ice is equal to the volume of water that ice displaces when floating. The danger is different: warming could lead to the melting of huge island and continental glaciers.

The biggest of them cover the Antarctic, where 90% of the world's ice is accumulated, and Greenland. The melting of this ice could lead to a catastrophe. But is there any reason to panic? The temperature rise of 3-6 degrees Celsius over the next century promised by pessimists could not have a significant influence on the Antarctic, where the average temperature is less than 40 degrees below zero.

The processes ongoing in the permafrost are even more complicated than those in the ice. All the winters of the last decade were more or less abnormal. Because of that, the permafrost in areas just beyond the Artic began receding and melting. The period of warming was tangible, but now it may be drawing to a close. Most natural processes on the earth are cyclical, having a shorter or longer rhythm. Yet no matter how these sinusoids look, a temperature rise is inevitably followed by a decline, and vice versa.

Studies of the ice core retrieved by Russia's Vostok Antarctic station show that this is what has been happening on earth for at least the last 400,000 years. Today, scientists say that the melting of the permafrost has stalled, which has been proved by data obtained by meteorological stations along Russia's Artic coast. We are now studying the influence of the atmosphere and snow cover on permafrost in space and time. In the permafrost zones, a layer melts in the summer, when the temperature rises above zero. However, in the winter this layer freezes again. This is a normal process: what melts, freezes. Yet if a winter is abnormally warm, this seasonal melted layer may not freeze back. Then the so-called "talik," a layer with a temperature of around zero, is formed. This is a very unpleasant thing for buildings and pipelines.

It seems that the permafrost should be melting if the temperature is rising. However, many areas are witnessing the opposite. The average annual temperature is getting higher, but the permafrost remains and has even started to spread. Why? An important factor is the snow cover. Global warming reduces it, therefore making the heat insulator for the permafrost thinner. Then even weak frosts are enough to freeze the ground deeper below the surface.

In many places, the frozen ground is 500-800 meters deep. Even if the highest warming forecast comes true and the temperature rises by 3-6 degrees, no more than 20 meters of frozen ground will melt. Some people are afraid that the melting permafrost will pollute the air with methane. However, frozen water takes up only 15% of the 20-meter layer, and the amount of gases dissolved there is insignificant. So we are unlikely to receive such unpleasant surprises from the permafrost within the next hundred years.

Today, scientists fear not so much global warming as changes in atmospheric circulation. In recent years, the so-called western shift has dominated, which means that air masses have been moving from the west eastwards. There has been little mention of the so-called meridian masses, moving from the south to the north and back. Now, however, the meridian shift has become more frequent.

If it goes south, it causes a spell of cold weather; if it goes north, it brings warm air masses with a lot of precipitation in the winter. This results in thaws and snow drifts on plains and in heavy snowfalls, avalanches and mudflows in the mountains. Meridian processes have been gaining in frequency lately, which promises different weather anomalies: unusually high and low temperatures, heavy rains and snowfalls and longer droughts, which in turn may lead to natural calamities.

SOME FRESH AIR NEEDED IN THE CLIMATE DEBATE

A comment from Nederland: "Global" concerns are causing neglect of important local problems

Recently, the IPCC, the climate panel of the United Nations, issued a new report. It focuses on the relation between the emission of greenhouse gases and the rise in globally averaged temperatures in the next one hundred years. A few degrees centigrade are forecast; in all likelihood this must be ascribed to the burning of fossil fuels. The sea level rise expected by the IPCC is on the order of four millimeters per year.

Though it would be easy to write an extensive commentary about these predictions, I feel no need to take issue with the IPCC on this point. Taking into account that the worldwide supplies of oil and gas are shrinking, and that Mr. Putin has threatened more than once to shut off the supply of natural gas to Europe, I agree it is necessary to pay more attention to energy-saving technology. Energy policy requires a high priority, both nationally and internationally.

But this does not mean that the climate debate is over now. I just mention a few points that bug me. Assuming that the IPCC numbers are reliable, I find the doomsday picture Al Gore is painting -- a six-meter sea level rise, fifteen times the IPCC number -- entirely without merit. The IPCC would have substantially lessened the acrimony in the climate debate if it had said so explicitly. It would have credited IPCC also if it had taken issue against the pressure exerted on professionals who doubt the majority view. It is unbecoming that American television weather forecasters who express doubts about global warming are likely to lose their jobs. The planned removal of State Climatologists George Taylor (Oregon), David Legates (Delaware), and Patrick Michaels (Virginia) also does not contribute to an atmosphere of unfettered professional discourse.

I protest the tendency to simplify the climate debate to a matter of fossil fuels, greenhouse gases, and a relatively minor global temperature increase. I protest the rude way geologists and astronomers are shoved aside. Whatever the IPCC staff thinks, it is not at all inconceivable that decreasing solar activity will lead to some cooling ten years from now. And if we look at the climate with a geologist's eye, we see all kinds of changes that have no discernible origin. In the long run we will enter a new ice age, but in the mean time we may encounter all kinds of ups and downs. The climate is always changing; that happened also when there were yet no people on this planet.

I protest vigorously the idea that the climate reacts like a home heating system to a changed setting of the thermostat: just turn the dial, and the desired temperature will soon be reached. We cannot run the climate as we wish. That is fortunate, because a bad season for farmers may be a boon for the tourist industry, deteriorating conditions for French farmers may mean improving conditions for their Polish colleagues, what is good for winter wheat may make things worse for corn, and so on. We are not dealing with a machine, but with Nature herself, and she is not easily mocked.

I want some fresh air in the climate debate, free of the acrimony surrounding the IPCC report. Fortunately there is plenty room for a breath of fresh air if we stop focusing on greenhouse gases to the exclusion of other matters. We obtain that freedom if we decide to think and act not only globally, but primarily locally. My colleague Roger Pielke Sr., professor emeritus of meteorology at Colorado State University and presently senior scientist at the University of Colorado in Boulder, has been investigating the effects of changing agricultural and forestry practices for many years. He doesn't stop at commiserating, as so many do, the climatic effects of tropical deforestation. He has demonstrated that increasing irrigation leads to enhanced summer precipitation, for example, in Colorado, Kansas, and Oklahoma. He also charted the effects of southward moving orange plantations on Florida's microclimate and found that the frost risks for the orange crops had moved southward as fast as the plantations themselves. Local climates can change this much by aggressive farming practices.

Another perspective opened by letting some fresh air in is to consider the concrete vulnerability of societies, in particular those in poor countries, to present climate. This is the vulnerability paradigm proposed by Pielke's son Roger Jr., who is a political scientist at the University of Colorado, and his colleague Daniel Sarewitz of Arizona State University. If the present climate problems of vulnerable regions are addressed forcefully, then 90% of the future problems there have become manageable. Don't bother to ponder whether or not climate change is responsible for Katrina's destructive impact, but state boldly that local, regional, and national authorities have ignored the warnings issued by the US Corps of Engineers for some twenty years. In my little lowlands country something similar has happened. Twenty years of warnings by the engineers in the Ministry of Public Works were thoughtlessly laid aside by the Dutch government. It finally woke up when the storm surge of February 1, 1953 claimed nearly two thousand lives. Then it was too late.

Let me summarize. In the climate, much more is at stake than the probable consequences of a slight temperature rise. The dwindling supplies of gas and oil and the direct effects of greenhouse gases get more than sufficient attention from the global community. But next to that there is a wide, only partially explored territory of local and regional vulnerabilities. Due to the incessant emphasis on the global aspects of the climate problem, this territory does not receive the attention it deserves. That is a shame.

Is this the cleverest "climate" policy yet?

Plan to rescue the world's forests



AUSTRALIA will form a global fund to fight illegal logging and forest destruction worldwide with the aim of halving the rate of deforestation and achieving greenhouse gas emission reductions 10 times greater than under the Kyoto Protocol. Along the lines of the AP6 Asia-Pacific climate pact, the $200 million Australian initiative will operate outside the Kyoto climate change protocol and will be funded by other developed nations to help developing nations preserve forests.

Germany, Britain and the US are expected soon to contribute to the fund, which will have Indonesia as its prime target. The UN has identified Indonesia as having the world's highest rate of forest clearing. Yesterday, British economist and climate change expert Nicholas Stern said Indonesia ranked third in the world as a greenhouse gas emitter, after the US and China, because of the destruction of forests.

The new world fund - with a similar structure to the six-party Asia-Pacific Partnership on Clean Development and Climate created early last year - will give John Howard momentum on the climate change issue as Labor paints him as negative and reluctant on global warming. Labor yesterday peppered the Prime Minister with questions on global warming and promised a $50 million program to subsidise solar panels on homes to cut power consumption and greenhouse emissions.

Mr Howard responded in parliament by pointing to a split between the state Labor governments and federal ALP over compulsory targets for solar and wind power. Mr Howard and Kevin Rudd yesterday both met Sir Nicholas, who said in his report on the effects of climate change last year that deforestation in developing countries was one of the greatest contributors to global warming. Sir Nicholas's report for the British Government predicted dire consequences unless immediate steps were taken to cut greenhouse gas emissions.

Mr Howard will announce the start of the global fund today as the Government attempts to take the political initiative on climate change. The forest fund, to be managed by the World Bank, is designed to help developing countries start sustainable forest industries, plant new forests, stop illegal destruction of rainforests, provide monitoring of forest production, education in forest management and help communities dependent on illegal rainforest timber find alternative jobs.

Deforestation accounts for 20per cent of global greenhouse gas emissions and it is estimated that a tonne of CO2 can be sequestered - or taken out of the atmosphere - through tropical reforestation for just $US2, a fraction of the cost of other technologies. The World Bank has estimated the mismanagement of forests costs the global economy $US10billion a year and says 85 per cent of the world's forests are not managed in a sustainable way.

In its submission to the Prime Minister's taskforce on global warming and emissions trading, the National Association of Forest Industries says forests "can play a significant role in addressing climate change concerns through the benefits of carbon sequestration and managed native forests and plantations".

Mr Howard told parliament yesterday that Australia would work towards achieving its target in cutting greenhouse gas emissions under the Kyoto Protocol but said he would not adopt policies that cost jobs. "Whilst there are quite a lot of things in Stern's report and in his work that we agree with, we will take decisions in the national interest," Mr Howard said. "History is littered with examples of nations having overreacted to presumed threats to their great long-term disadvantage."

Mr Howard highlighted a split between the state Labor governments and federal ALP over the policy on renewable energy to combat climate change. In a submission to the Prime Minister's taskforce, the state governments have recommended that mandatory targets for generating power from solar, wind and other renewable sources be phased out when anemissions trading system is introduced. The states say a market-based system of encouraging greenhouse gas reduction through emissions trading is not compatible with mandatory targets. The federal ALP's policy "supports a mandatory renewable energy target which will promote the growth of renewable energy industries such as solar and wind power". "Labor will ensure a genuine and substantial increase in the percentage of Australia's energy generated from renewable sources," the policy says.

But the states have recommended mandatory renewable energy schemes be discontinued or not renewed. When asked about renewable energy targets in parliament, Mr Howard said that as he was being asked to expand mandatory targets the states wanted to phase them out. "This is at the heart of this debate - you cannot run power stations on renewables. Yet the Leader of the Opposition and those who sit behind him believe you can," he said.

Stern warnings on climate consensus: The thinking man's climate change extremist hits town

An editorial from "the Australian" below

BRITAIN'S climate change emissary, Nicholas Stern, has left something for everyone in his lightning visit to Australia to warn of the likely costs of not taking precautionary action on global warming. The federal Government was given a tick for considering nuclear energy as an answer to cutting carbon emissions. Labor was given encouragement for setting a target to reduce the emissions. The coal industry was assured it was a logical long-term player in the world energy business and that Australia was perfectly placed to research clean coal technology, which would make a profound impact if it proved viable.

Global warming activists, meanwhile, would be heartened by Sir Nicholas's view that Australia should sign the Kyoto climate change protocol and was morally obliged to act on cutting its carbon emissions, even though in real terms any cuts would have a negligible impact on the global situation.

Set against Al Gore's hyperbolic visions of doom, Sir Nicholas can appear to be almost a voice of reason. This is because, unlike Mr Gore, who may morph into a climate change- fuelled US presidential candidate at any moment, Sir Nicholas is a serious bureaucrat and former World Bank chief economist. This should not obscure the fact, however, that he was handpicked to undertake the review of climate change by British Prime Minister Tony Blair for political as much as altruistic reasons.

British politicians have seized on climate change with what appears an almost religious zeal. Both major parties are attempting to outbid each other with climate change responses that promise austere measures for British citizens including the possibility of rations and progressive taxes on air travel. While there have been criticisms of Sir Nicholas's research, including from this newspaper, he has succeed in engaging business in the debate. Where Mr Gore has adopted the rhetoric of zealotry and exaggeration, Sir Nicholas has employed the logic of an insurance actuary. He has persuaded business to accept it makes economic sense to address the issue of climate change now, because if the science proves true, the cost will be much higher the longer it is left. This precautionary principle is well understood by the business mind, which also sees the potential for profit in a carbon trading regime.

That said, Sir Nicholas has not been shy of indulging in a little headline-grabbing of his own, with warnings that the cost of responding to climate change will equal two world wars and a depression. However, he has not overdramatised the state of scientific confidence on the impact of global warming, or the human contribution to climate change, to the same extent as others, notably Mr Gore and Australian of the Year Tim Flannery. Nonetheless, Sir Nicholas's call for harsh carbon emission targets, with reductions of between 60and 90 per cent, are best viewed in the context of the continuing need to draw attention to the issue. A target will always only be a target, and success in meeting it will depend on the success of new technology and innovation.

In political terms, John Howard had little choice but to meet Sir Nicholas, but the Prime Minister has made it clear the Government's response would be guided by protecting jobs and safeguarding the economy. If the Opposition sees Sir Nicholas's visit as a welcome precursor to this weekend's climate change talkfest, it would be wise to take a leaf from the Stern book of diplomacy and ability to deal with business. Having succeeded in getting business to the table, Labor must now satisfying the diverse groups without wrecking its claim to economic credibility.

For a lesson in the art of clever climate change solutions and politics, it's hard to beat Mr Howard's plan to combat illegal global logging, which could deliver 10 times the carbon savings of Kyoto.

Just another end-is-nigh climate guy?

A comment from Canada



Here's the headline news from Tim Flannery, Australian of the Year: The climate is changing much faster than we thought even a short time ago. These changes will be vast and certainly catastrophic if we do not act. Thousands of species -- including our polar bear -- are headed for extinction. The collapse of the Gulf Stream could trigger a new nuclear arms race and usher in a nightmare era of global conflict. Left unchecked, climate change could well bring about the end of our civilization.

Whew. Pretty grim stuff. Yet Mr. Flannery swears he's no alarmist. "Just because the news is alarming doesn't mean the messenger is alarmist." His book The Weather Makers is riding high on the international bestseller lists, and he's a hot commodity on the speaking circuit. (He's addressing a think-tank conference for Canadian politicians today.) In Australia, where a severe drought has pushed climate change to the top of the agenda, he's at least as influential as Al Gore. The two have other things in common. Both simplify the science, cherry-pick the evidence and play down the uncertainties. They make it seem as if massive action is a no-brainer.

Too right, mate. We all want to do something. But what? How? What kinds of policies make sense? And what about the rest of the world? China, the fastest-growing carbon emitter on the planet, is building a new coal plant every week. Why should it sacrifice its prosperity to save our polar bears?

Mr. Flannery confesses that he gave short shrift to the dilemma of big developing countries. "The reason I don't talk about that is that it's a perfect formula for doing nothing." The flip side of this end-is-nigh pessimism is a remarkably cheery faith in new technologies and the prospect of global co-operation. "There is quite a significant shift even in China," he says optimistically. "They're talking a lot about renewable energy. The richest man in China makes solar panels." One day, he predicts, China could be the supplier of cheap solar panels to the world.

Maybe so. But Mr. Flannery prefers to gloss over the unpalatable economic tradeoffs that people and their governments are probably not prepared to make. For example, he thinks Australia ought to get out of the coal business. Like Mr. Gore (and unlike David Suzuki, who believes we must drastically cut our standard of living in order to avert Armageddon), Mr. Flannery basically promises climate gain without pain. He's also partial to massive social-engineering schemes. For example, he argues that the only equitable way to reduce emissions is to grant every human being an equal "right to pollute" with greenhouse gases. Under this system, developed countries would have to buy enough carbon credits from poor countries to cover their emissions. This would have the added (in his view) advantage of redistributing wealth from the greedy West to the impoverished rest. Does such a scheme have a chance? Not on this planet.

Mr. Flannery admits that emissions trading in Europe has been a flop (he blames the Italians for gaming the system, although they're not the only ones), and that the Kyoto targets are meaningless. He's for Kyoto anyway. "It's like a baby. It's useless when it's born. It needs nurturing, and then you can build it into anything you want it to be." He also points out that everything in his book is based on reputable scientific studies published in major journals, such as Nature.

What he doesn't say is that he tends to pick the most sensational studies and ignore the ones that contradict them. About the starving polar bears, he writes: "It looks as if the loss of nanuk may mark the beginning of the collapse of the entire Arctic ecosystem." Just one problem. The polar bear population is booming. And they've weathered climate changes far longer than humans have. Mr. Flannery was a bit defensive when I raised this. "You'll always find an expert to contradict any study."

Mr. Flannery is a very influential man. I hope his predictions of imminent catastrophe are wrong, because his ideas for tackling global warming are pretty lame. Do I have better ones? Nope. My point is, the real debates have only just begun.

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
