A GREENIE FAITH-HEALING MEETING

There has just been a meeting of the American Association for the Advancement of Science that seems to have focused on propping up the faith of true believers in global warming. The participants were presented with a big selection (with "selection" being the relevant word) of evidence to show that the earth has been warming up in recent years. Some excerpts:

Scientists reported Friday they have detected the clearest evidence yet that global warming is real -- and that human industrial activity is largely responsible for it. Researchers at the annual meeting of the American Association for the Advancement of Science cited a range of evidence that the Earth's temperatures are rising:

-- The Arctic regions are losing ice cover.

-- The populations of whales and walrus that Alaskan Eskimo communities depend on for food are crashing.

-- Fresh water draining from ice and snow on land is decreasing the salinity of far northern oceans.

-- Many species of plankton -- the microscopic plants that form the crucial base of the entire marine food web -- are moving north to escape the warming water on the ocean surface off Greenland and Alaska.

Ice ages come and go over millennia, and for the past 8,000 years, the gradual end of the last ice age has seen a natural increase in worldwide temperatures, all scientists agree. Skeptics have expressed doubt that industrial activity is to blame for world's rapidly rising temperatures.

But records show that for the past 50 years or so, the warming trend has sped up -- due, researchers said, to the atmospheric burden of greenhouse gases produced by everything industrial, from power plants burning fossil fuels to gas-guzzling cars -- and the effects are clear. "We were stunned by the similarities between the observations that have been recorded at sea worldwide and the models that climatologists made," said Tim Barnett of the University of California's Scripps Institution of Oceanography. "The debate is over, at least for rational people. And for those who insist that the uncertainties remain too great, their argument is no longer tenable. We've nailed it."

Barnett and other experts marshaled their evidence and presented it to their colleagues for the first time at a symposium here. For the past 40 years, Barnett said, observations by seaborne instruments have shown that the increased warming has penetrated the oceans of the world - - observations, he said, that have proved identical to computer predictions whose accuracy has been challenged by global-warming skeptics. The most recent temperature observations, he said, fit those models with extraordinary accuracy....

"Ice is in decline everywhere on the planet, and especially in the Arctic, " said Ruth Curry, a physical oceanographer at the Woods Hole Oceanographic Institution, "and there is large-scale drying throughout the Northern Hemisphere."

Ice cores drilled deep into the Greenland ice cap show that salinity of the ice at the upper layers of the cores has decreased sharply due to the incursion of fresh water draining from melting snows on the surface, she reported, and land ice and permafrost are in decline all around the Arctic. In the meantime, she said, measurements show that salinity of the ocean waters nearer the equator has increased as the rate of evaporation of warmer tropical and subtropical oceans quickens.

It may take several centuries for all the ice that covers Greenland to melt, Curry said, "but its release of fresh water will make sea-level rise a very significant issue in this century." In fact, she said, changes in the freshwater balance of the oceans has already caused severe drought conditions in America's Western states and many parts of China and other Asian countries.


But no-one has ever disputed that the earth's temperature rises and falls. The only important question is whether 20th century industry caused any of the current apparent warming. And only one of the above reports appears to offer an answer to that -- the report by oceanographer Barnett. Here is what I said yesterday on "Dissecting Leftism" about the Barnett report:

This report by Tim Barnett, of the Scripps Institution of Oceanography in La Jolla, California -- saying that the recent small rise in the earth's temperature can only be explained by man-made gas emissions -- has got an amazing amount of publicity. But the report has yet to be subjected to peer review, let alone be published in an academic journal. It shows how desperate the global warmers have got for any shred of comfort. The language of the author of the report -- that "rational" people could not doubt his conclusions -- has certainly got more to do with Barnum than science. I suppose the amusing part is that the warmers have finally found some real-world data that their models fit. Most real-world data does not. I guess they had to get lucky eventually.


And what sort of a scientific meeting is it that presents only positive evidence in favour of one point of view? It sounds more like a religious revival meeting than a scientific gathering. Or is it just that all the evidence points one way? Far from it. Just look at the next three stories below for starters.





WICKED N.Z. GLACIER GROWS INSTEAD OF SHRINKING!

Three years ago, climate change activists said that a glacier in the deep south of New Zealand was a "global warming casualty," shrinking because of the human impact on global climate patterns. This week, a company that takes visitors over the popular tourist attraction confirmed that the Franz Josef Glacier is in fact advancing, growing several meters by the day, following an unseasonably cool summer in the southern hemisphere.

As the Kyoto Protocol comes into effect around the world on Wednesday, the ebb and flow of the glacier has turned the spotlight once again onto environmentalists' claims. Mark Mellsop, manager of the Franz Josef Glacier Guides company, said the glacier's flow rate in the center was about three meters a day, while the front -- known as the "terminal face" -- was pushing up against a large rockface, spilling over and around it. Within weeks the rock would be completely covered. "We've had a couple of years of very good snowfalls in winter, and we've had a really unusually cold summer -- about the coldest in New Zealand for 60 years, " he said. "Those things have all come together to cause the glacier to push forward. "This isn't particularly unusual; it's just that in general glaciers are retreating around the world. People find this unusual because of the general stories of global warming."

Mellsop said a change in weather had both an immediate and longer-term effect on the glacier, which is visited by 60,000 people a year. In the short term, cooler temperatures slow down melting and snow increases the flow-rate. "Beyond that, there's also a downstream effect. If you have heavy snowfalls one year, you're likely to get increased volumes of ice coming down the glacier three-to-five years later."

Mellsop said the 11 kilometer-long glacier was steeper than most, and was therefore "very, very sensitive to climate change." Until the end of the 20th century the glacier advanced for 15 years. Between 1999 and 2003 it retreated before recently starting to advance again. Asked whether he thought the gloomier predictions of green activists were likely to bear out, Mellsop said "only if the people who are talking about climate are accurate.".....

In 2002, Greenpeace declared that Franz Josef was a "global warming casualty." "Warmer temperatures and altered snow and rain patterns from climate change are resulting in the retreat of glaciers the world over," a climate campaigner for the group said at the time. Robbie Kelman made it clear where Greenpeace placed the blame for this: "Increased temperatures brought about by greenhouse polluting gases like methane and the burning of fossil fuels, coal, oil and gas, are destroying glaciers. Unless we break our addiction to fossil fuels, we risk the wholesale destruction of glaciers."

No one denies that the Franz Josef glacier both advances and retreats and that weather patterns play a role, but problems arise when a link is drawn with claims that the world's climate is steadily and dangerously rising. "Glaciers advance and retreat not only because of temperature but also because of precipitation," Prof. Chris de Freitas of the School of Geography and Environmental Science at Auckland University said Wednesday. "Just because a glacier or group of glaciers is doing one thing or another -- whether advancing or retreating -- doesn't mean to say it's an indicator of global climate. It's an indicator of regional climate variability, and to link it to global climate change is absurd."

Pointing to another favorite argument of the activists, de Freitas said there was a small part of the Antarctic Peninsula that showed warming, and the current speculation was that this was a result of warming currents. "But the vast majority of the Antarctic continent is actually cooling. To say that's an indicator of global cooling is as absurd as to say that's an indicator of global warming. "It's an environmental condition that attracts attention, but to link it to global warming is such a leap that is shows what I would consider a naive or simple understanding of events."

He said the whole climate change debate had become "contaminated by speculation" by scientists, campaigners and journalists. "If you stand back, the evidence suggests that we don't have catastrophic change on our hands. If anything, the evidence over the last 10 or 15 years suggests that the global climate system isn't as sensitive as some of us first thought to changes in greenhouse gases.".....

The Auckland academic is one of many around the world whom green campaigners have labeled "skeptics." He prefers to call himself a climate change "agnostic" and has strong words for the other camp. "The whole global warming issue has become very political. Even among scientists, there are people protecting their position ... or their funding, or their ideology. Science should be open-minded. Good science thrives on debate and discussion and not the reverse. What's happened is the reverse - you claim consensus and marginalize anyone who disagrees with the mainstream. That's very unscientific."

Beyond the scientists, de Freitas said, there were other vested interests. "It's not just the scientists. It's everyone involved in the impacts, the policy people, the economists, there are whole bureaucracies .... It's a whole industry, you can't kill it off. "People like myself who utter criticisms that slow this momentum down are considered outrageous. It's very hard for members of the public to get what I consider a useful perspective of the issue."

DROUGHT CAUSED BY GLOBAL WARMING -- NOT

Historical droughts in the Columbia River Basin were more severe than anything in recent memory, including the drought of 1992-93, scientists said Monday. A study of tree rings found four droughts between 1750 and 1950 that were "much more severe than anything in recent memory" because they persisted for years.

One drought that started in the 1840s lasted 12 years. Flows on the Columbia River were at least 20 percent below long-term averages and might have been much lower, said lead author Ze'ev Gedalof of the University of Guelph in Ontario. Reliable river flow records go back only about 75 years. But tree-ring data reveals how much trees grow each year, a reflection of climate. "Imagine what a drought lasting that long would do to the resources and economy of the region today," says Dave Peterson of the U.S. Forest Service and the University of Washington's College of Forest Resources.

Five other multiyear droughts were identified, around 1775, 1805, 1890, 1925, and one in the 1930s coinciding with the Dust Bowl era. The study was published recently in the Journal of the American Water Resources Association. "This is a wakeup call for the importance of drought planning, and seeking ways to restore some flexibility in Western water supply systems that have a limited ability to respond to multiyear droughts," said co-author Nate Mantua of the Climate Impacts Group based at the University of Washington. "The drought like the one indicated in the 1840s, for instance, simply hasn't been part of the modern water systems experiences."

The study is a microcosmic look at one drainage. But other research has reached similar conclusions. A much broader study covering the western United States and going back 2,000 years suggests that droughts in recent memory are indeed relatively minor.

REMINDER: WATER VAPOUR IS BY FAR THE MAJOR GREENHOUSE GAS

So what do Greenies do about that inconvenient fact? Ignore it, of course!

Generally understood, but rarely publicized is the fact that 95% of the greenhouse effect is due solely to natural water vapor. Of the remaining 5%, only 0.2% to 0.3% of the greenhouse effect (depending on whose numbers you use) is due to emissions of carbon dioxide and other gases from human sources. If we are in fact in a global warming crisis, even the most aggressive and costly proposals for limiting industrial carbon dioxide emissions would have an undetectable effect on global climate. However, significant efforts to limit the emission of greenhouse gases in the United States are currently underway.

Carbon Dioxide from all coal burning worldwide comprises only 0.013% of the greenhouse gases in Earth's atmosphere.

In Kyoto, Japan in December 1997 former President Clinton and former Vice President Gore agreed to commit the United States to significant future reductions of carbon dioxide emissions, principally by cutting the use of fossil fuels by as much as 30% over the next 10 years. It is assumed that these drastic proposed measures will have a real effect on protecting Earth's climate-- an assertion that many climate experts are reluctant to support.

While scientists are currently searching for proof that emissions from the burning of fossil fuels are warming the planet, there exists no solid proof at this time. The strongest evidence for a problematic greenhouse effect is data generated from computer models which predict about 1.5 degrees C of warming in the next 50 years unless something is done to change the rate of carbon dioxide entering the atmosphere. While computer climate models may eventually be able to predict future climate change, so far the ones we have are very unreliable-- unable even to accurately predict current climate conditions using current climate data.

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 to promote themselves as wiser and better than everyone else, truth regardless.
