The latest scare

We have to wait until the very end of the article to find out the full truth

The oceans are losing the capacity to soak up rising man-made carbon emissions, which is increasing the rate of global warming by up to 30 per cent, scientists said yesterday. Researchers have found that the Southern Ocean is absorbing an ever-decreasing proportion of carbon dioxide in the atmosphere. The excess carbon, which cannot be absorbed by the oceans, will remain in the atmosphere and accelerate global warming, they said. The reduced ability to absorb carbon is thought to be a result of high winds acting on ocean currents bringing deeper waters that already contain high levels of carbon to the surface.

The higher winds are themselves believed to have been caused by climate change due to a combination of changes in the ozone layer and carbon emissions. The scientists from countries including Britain, France and Germany, said their findings marked the first time that one of the world's natural "carbon sinks" had been shown to be weakened by Man's own actions.

Ian Totterdell, a climate modeller at the Met Office Hadley Centre, described the research as "an important piece of work". He said: "This is the first time we have been able to get convincing evidence that a change in the uptake of CO2 by the oceans is linked to climate change. "It's one of many feedbacks we didn't expect to kick in until some way into the 21st century."

While a reduction in absorption rates by carbon sinks has long been forecast, the discovery that the Southern Ocean is mopping up less of Man's carbon emissions has come at least two decades earlier than expected. The Southern Ocean is the world's biggest marine carbon sink and accounts for 15 per cent of all the carbon taken out of the atmosphere. Temperatures are already predicted to rise by almost 1.5C (2.7F) by the middle of the century, without taking into account any further emissions caused, for example, by the rapid construction of fossil fuel power plants in China and India.

The weakening of the Southern Ocean's absorption rates- which could be in the range of 5 to 30 per cent- is likely to result in an increase in the rate at which temperatures rise, scientists say. "This is serious," said Corinne Le Qu, of the University of East Anglia (UEA) and the British Antarctic Survey (BAS), two of the world's leading environmental research centres. "This is the first time that we've been able to say that climate change itself is responsible for the saturation of the Southern Ocean sink. "With the Southern Ocean reaching its saturation point more CO2 will stay in our atmosphere. Since the early 1980s the carbon sink hasn't changed. In the same period the emissions have gone up by 43 per cent." Dr Le Qu led a team measuring atmospheric carbon dioxide, which found that, despite this rise in emissions since 1981, the quantity absorbed by the ocean was static.

Since the industrial revolution an estimated 500 giga-tonnes of carbon dioxide has been released into the atmosphere through the use of fossil fuels, cement manufacture and changes in land use. About a quarter of this has been absorbed by the oceans and a further quarter taken up by vegetation.

The research, published in Science, identified changes in wind patterns caused by climate change as being the direct cause of the weakened ability to absorb carbon dioxide. While able to pinpoint the hole in the ozone layer and carbon emissions as the man-made causes of the increased winds, the researchers were unable to identify which of them had the greater effect. The net quantity of carbon dioxide absorbed by the Southern Ocean remained at 0.3 billion tonnes a year from 1981 to 2004, according to calculations by the research team. In 1981 it absorbed 0.6 billion tonnes from the atmosphere but emitted 0.3 billion tonnes back into it. In 2004 it absorbed 0.8 billion tonnes but emitted 0.5 billion tonnes. In the report they said that climate models project more intense Southern Ocean winds if CO2 levels continue to increase over the next century.

The researchers accepted there were limits to the data available from the Southern Ocean and that "the magnitude of the CO2 sink is heavily disputed". Professor Chris Rapley, director of BAS, said uncertaintities remained, but the findings were "a serious concern". He said the reduced efficiency of the ocean to act as a carbon sink would make it harder to reduce emissions to levels that were low enough to limit temperature rises to 2C.

Czech president calls for rational debate on global warming, rejects "current hysteria"



Czech President Vaclav Klaus on Wednesday called for a rational debate on global warming, rejecting what he called "hysteria" driven by enviromentalists. "Let's bring the debate to whether the 0.6 (degree Celsius warming over the last century) is much or little, how much Man has contributed to the warming and ... if there is anything at all Man can do about it," Klaus said when presenting his book "Blue, Not a Green Planet."

He charged that groups other than scientists have now seized on the topic and ambitious environmentalists are fueling a global warming hysteria that has no solid ground in fact and allows manipulation of people. "It is about a key topic of our time, and that is the topic of human freedom and its curtailment," Klaus said. "The approach of environmentalists toward nature is similar to the Marxist approach to economic rules, because they also try to replace free spontaneity of the evolution of the world (and of mankind) with ... global planning of the world's development," Klaus writes in his book. "That approach ... is a utopia leading to completely other than wanted results," he says.

Klaus, an economist by profession, has repeatedly warned that policy makers are pushed by the widespread fear of global warming to adopt enormously costly programs that eventually may have no positive effect. Klaus served as Czechoslovak finance minister after the 1989 fall of communism and as Czech prime minister after Czechoslovakia split into the Czech Republic and Slovakia in 1993. As president, he now has mainly ceremonial powers.

ERAU professor seeks balance in global warming debate

Nick Shipley, an Embry-Riddle Aeronautical University freshman, had just spent a week of classes watching two films with polar-opposite conclusions about global warming. "After watching 'An Inconvenient Truth,' I was relatively convinced," Shipley said one day last month in class. "(Al Gore) did a good job in presenting his points very methodically one after the other. They all build up to essentially prove his point. "After watching 'The Great Global Warming Swindle,' my thinking completely changed," he said. "I kind of did a complete flip-flop."

College students aren't the only ones being confronted with climate change, its causes and what -- if anything -- can be done about it. A Democratic Congress, an Academy Award for "An Inconvenient Truth" and continuing United Nations' proclamations have all contributed to the drumbeat for reducing carbon dioxide emissions as a strategy for fighting global warming. Some scientists are concerned the forces that are shaping debate and making policy decisions are not based on truths -- convenient or not.

James Wanliss, a space physicist who teaches at Embry-Riddle, showed students the two films in an honors course titled "The Politics and Science of Fear" because he said more and more the public is being sold one side of an issue with many dimensions. "I fear that attempts are being made to purposefully subvert the public understanding of the nature of science in order to achieve political goals," he wrote in an e-mail. "Science is not about consensus, and to invoke this raises the hackles of scientists such as myself. The lure of politics and publicity is no doubt seductive, but it nevertheless amazes me that so many scientists have jumped on the bandwagon of consensus science, apparently forgetting or ignoring the sad history of consensus science."

"An Inconvenient Truth," the documentary starring Gore and a lot of graphs, makes the case that humans have contributed mightily to a 1-degree rise in the Earth's temperature in the last 50 years. It uses images of melting ice caps and dying polar bears to nudge viewers toward action for reasons of morality. "The Great Global Warming Swindle," an anti-Gore documentary, doesn't question the Earth's temperature increase but takes to task the questions of why and what's next. For example, it suggests solar activity may have more to do with the planet's warming than carbon dioxideemissions.

Wanliss said he doesn't necessarily subscribe to either film, but believes his students -- and the public -- should remain skeptical of theories such as Gore's explanation of global warming. Other Embry-Riddle scientists are less outspoken than Wanliss, but one -- John Olivero, professor and chairman of the department of physical science -- allowed that skepticism is an essential tool of the scientific method. "Science lives with internal conflict all the time," Olivero said. "Part of what we have to do is continually challenge each other." That process, they say, leads scientists closer to truths that may be elusive for lifetimes.

The truths of global warming are, if not inconvenient, incomprehensible, Wanliss argues. "The atmosphere is incredibly complicated, and we know very little about it," he said. "We are studying a system which is so big . . . we don't know what all the variables are." Pointing to quotes in magazine articles, Wanliss says Gore and the producers of the "Swindle" film are purposefully overstating their science as a means to a political end.

His views are certainly controversial. Penelope Canan, a professor of sociology at the University of Central Florida, leans toward Gore's way of thinking. "There's really no doubt that human activities have altered the global carbon cycle and the natural balances that have thickened the blanket of greenhouse gases that have kept our planet like Baby Bear's soup for thousands of years," she said in an e-mail. "I am certain that the data presented by Al Gore was digested by hundreds of thousands of research hours and peer-reviewed data by the world's leading scientists."

Sam Rabin, a freshman activist at Stetson University who helped screen "An Inconvenient Truth" on his campus, said many policymakers avoid difficult decisions that may come from carbon dioxide emission limitations, while journalists ramp up the skeptics' arguments in the name of balance. "This is horribly misguided and counterproductive," Rabin wrote in an e-mail. "There is virtually no scientific debate about global warming or its cause." But Wanliss' students at Embry-Riddle leaned toward the skeptical. The professor said that is an important lesson about science. "You want certainty, but it's hard to get that," he said. "Science isn't about certainty."

Greenies as fire-worshippers

For those who lived under communist rule - like the author of this piece - it is obvious that science played the central role in their ideology. Starting with Marx, communists claimed that their ideology was based completely upon rational scientific calculation, as opposed to traditional faith. They claimed that science can account for not only the material world, but also the world of ideas and social behavior. That explains why communists always paid great attention to economics and sociology. The failure of those pseudo-scientific disciplines could itself be a topic for a paper. However, here I am only discussing one interesting feature of the scientific cult - its close relation to fire-worship.

Fire was undoubtedly the first and the most important scientific discovery in the history of the mankind. By learning to use fire, people gained a decisive advantage over all other species. Fire made it possible for people to populate territories with cold climate and use a wider range of nutrients. I cannot imagine any possible discovery which would influence the life of modern people to the same extent as fire influenced the life of our ancestors. Hence, fire-worship at that time was equivalent to the belief in the power of science.

The relation of science and fire is especially obvious from the documentary films about science. There, scientists are always shown with something related to fire. It could be a laser, a faraway star or galaxy, an atomic reactor, a starting rocket, or at least twinkling lights on the instrument board. Earlier, it used to be a blast-furnace or a steam-engine. I wonder if the current assault on smoking is driven by the desire to exterminate the competitors, namely the non-scientific fire users.

During the medieval period of the Dark Ages people probably did not believe in science very much. However, as the instrumentation and means of production became more and more complicated and science started to play an important role in European societies, the worship of science reappeared. Not surprisingly, the name of that historical period is the Enlightenment. The means for propagandizing the science cult is education; those who do not want to educate themselves about science are usually called "dark" people.

Undoubtedly, the Global Warming Catastrophe is closely related to science. It was predicted by scientists and can be avoided only by scientific means. With Global Warming, the religion of science has obtained its Apocalypse. But what is the reason for that terrible punishment? It is the unwise burning of fuels, burning by rough uneducated people who are not entitled to use the fire. It is the desecration of fire by the mankind. Scientists aloner are entitled to burn fire and distribute the power of fire to the people, but only in the amounts they consider sufficient. Clearly, they cannot and do not want to prohibit fire, because the fire is their power, but they want to be the only ones in the control of the fire. By the way, the accusation that the Bush administration has the desire to control Mid-Eastern oil is a typical projection of one's aggression on the enemy.

In the light of the above piece, what else could be expected from the scientific fire worshippers? Probably, the prohibition of matches, grills and fireplaces as unsafe, restrictions on fireworks, and of course the prohibition of firearms. Later one may expect limitations on the use of electric power and natural gas, as well as recommendations to avoid cooking and frying. The prohibition of all combustive liquids, including alcohol. Finally, any unauthorized use of fire will be prohibited.

And Science will prevail.

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
