Denying Global Warming Environment

A remarkable article from New Scientist describes organized efforts to intimidate and discredit scientists who call public attention to global warming:

Kevin Trenberth reckons he is a marked man. He has argued that last year's devastating Atlantic hurricane season, which spawned hurricane Katrina, was linked to global warming. For the many politicians and minority of scientists who insist there is no evidence for any such link, Trenberth's views are unacceptable and some have called for him step down from an international panel studying climate change. "The attacks on me are clearly designed to get me fired or to resign," says Trenberth.

The attacks fit a familiar pattern. Sceptics have also set their sights on scientists who have spoken out about the accelerating meltdown of the ice sheets in Greenland and Antarctica and the thawing of the planet's permafrost. These concerns will be addressed in the next report by the Intergovernmental Panel on Climate Change (IPCC), the global organisation created by the UN in 1988 to assess the risks of human-induced climate change. Every time one of these assessments is released, about once every five years, some of the American scientists who have played a part in producing it become the targets of concerted attacks apparently designed to bring down their reputations and careers. At stake is the credibility of scientists who fear our planet is hurtling towards disaster and want to warn the public in the US and beyond.

So when the next IPCC report is released in February 2007, who will be the targets and why? When New Scientist spoke to researchers on both sides of the climate divide it became clear that they are ready for a showdown. If the acrimony were to become so intense that American scientists were forced to stop helping in the preparation of IPCC reports, it could seriously dent the organisation and rob the world of some significant voices in the climate change debate. [...]

Another scientist to suffer the ire of the sceptics was Michael Mann of Pennsylvania State University in University Park. He was attacked after the IPCC assessment in 2001, which highlighted his "hockey stick" graph showing that temperatures began a rapid rise in recent decades and are now higher than at any time over the past thousand years. The sceptics accused Mann of cherry-picking his data and criticised him for refusing to disclose his statistical methods which, they claimed, biased the study to show recent warming . Last year, Texas Republican Congressman Joe Barton, chair of the House Committee on Energy and Commerce, ordered Mann to provide the committee with voluminous details of his working procedures, computer programs and past funding. Barton's demands were widely condemned by fellow scientists and on Capitol Hill. "There are people who believe that if they bring down Mike Mann, they can bring down the IPCC," said Santer at the time. Mann's findings, which will be endorsed in the new IPCC report, have since been replicated by other studies.

Santer says, however, that he expects attacks to continue on other fronts. "There is a strategy to single out individuals, tarnish them and try to bring the whole of the science into disrepute," he says. "And Kevin [Trenberth] is a likely target." Mann agrees that the scientists behind the upcoming IPCC report are in for a rough ride. "There is already an orchestrated campaign against the IPCC by climate change contrarians," he says. [...]

Many of the IPCC's authors...claim there is an extensive network of lobby groups and scientists involved in making the case against the IPCC and its reports. Automobile, coal and oil companies have coordinated and funded past attacks on them, the scientists say. Sometimes this has been done through Washington lobby groups such as the Competitive Enterprise Institute (CEI), whose officers include Myron Ebell, a former climate negotiator for George W. Bush's administration. Recently, the CEI made television advertisements arguing against climate change, one of which ended with the words: "Carbon dioxide, they call it pollution, we call it life." CEI's past funders include ExxonMobil, General Motors and the Ford Motor Company.

Some sceptical scientists are funded directly by industry. In July, The Washington Post published a leaked letter from the Intermountain Rural Electric Association (IREA), an energy company based in Colorado, that exhorted power companies to support the work of the prominent sceptic Pat Michaels of the University of Virginia, Charlottesville. Worried about the potential cost of cleaning up coal-fired power plants to reduce their CO2 emissions, IREA's general manager, Stanley Lewandowski, wrote: "We believe that it is necessary to support the scientific community that is willing to stand up against the alarmists... In February this year, IREA alone contributed $100,000 to Dr Michaels." [...]

Another sensitive area is the concern that existing models of ice sheets on Greenland and Antarctica massively underestimate future melting and consequent sea-level rise. "Our understanding of the dynamics of ice-sheet destruction has completely changed in the last five years," says Richard Alley of Penn State University, a lead author of the chapter on ice sheets who expects to find himself in the firing line over this issue. "We used to think it would take 10,000 years for melting to penetrate to the bottom of the ice sheet. But now we know it can take just 10 seconds," he says.

The rethink has come from the discovery that when surface water from melting ice drains down though crevasses it can lubricate the join between ice and bedrock. This mechanism appears to explain the faster discharge of ice from Greenland into the Atlantic, but it has yet to be incorporated into ice-sheet models, which still assume that the limiting factor is the rate at which heat penetrates through solid ice. [...]

A third focus for debate will be the way the IPCC treats recent reports of climate change disrupting the natural carbon cycle more than anticipated. This has to do with the release of large amounts of CO2 from rainforests and soils, and methane from permafrost and beneath continental shelves, possibly speeding up global warming. "These are factors not included in the current models, which may cause us to underestimate warming," Mann says. [...]

The US Senate's Environment and Public Works Committee under its chairman James Inhofe has begun investigating NCAR, Trenberth's employer. Inhofe has repeatedly written to NCAR and other agencies demanding details about financial and contractual arrangements with their employees and with federal funding agencies such as the National Science Foundation (NSF). In a letter to the NSF in February, Inhofe said he needed the information to help him in "researching, analyzing and understanding the science of global climate change". Inhofe has a record of hostility to the idea of climate change, having asked on the Senate floor in July 2003: "Could it be that man-made global warming is the greatest hoax ever perpetrated on the American people? It sure sounds like it."

NCAR is not commenting on Inhofe's investigation, but many climate scientists contacted by New Scientist regard it as a tactic designed to intimidate those working on the IPCC report. "Inhofe's actions appear to be an effort to discourage leading US scientists from being involved in international scientific assessment processes such as the IPCC," Mann says.

This is potentially disastrous for the IPCC. Out of 168 scientists listed as lead authors or reviewers involved in assessing the science of climate change, 38 are from the US - more than twice as many as the second-largest national grouping, the British. [Emphasis added]

We've linked to article after article that shows that global warming is advancing more rapidly than anyone expected and that a variety of feedback loops are kicking in that will tend to accelerate it further. E.g., warming melts the permafrost; which releases methane, a potent greenhouse gas; which causes more warming; which melts more permafrost, etc., etc. It has never been clear in most of those articles if the feedback loops are already taken into account in current computer models of global warming. Apparently not, which means we're worse off than we think. Cause for alarm, indeed.

So, did the global warming question mark looming over planet Earth just get bigger, or smaller?

The link between Mind and Social / Environmental-Issues.

The fast-paced, consumerist lifestyle of Industrial Society is causing exponential rise in psychological problems besides destroying the environment. All issues are interlinked. Our Minds cannot be peaceful when attention-spans are down to nanoseconds, microseconds and milliseconds. Our Minds cannot be peaceful if we destroy Nature.

Industrial Society Destroys Mind and Environment.

Subject : In a fast society slow emotions become extinct.
Subject : A thinking mind cannot feel.
Subject : Scientific/ Industrial/ Financial thinking destroys the planet.
Subject : Environment can never be saved as long as cities exist.

Emotion is what we experience during gaps in our thinking.

If there are no gaps there is no emotion.

Today people are thinking all the time and are mistaking thought (words/ language) for emotion.

When society switches-over from physical work (agriculture) to mental work (scientific/ industrial/ financial/ fast visuals/ fast words ) the speed of thinking keeps on accelerating and the gaps between thinking go on decreasing.

There comes a time when there are almost no gaps.

People become incapable of experiencing/ tolerating gaps.

Emotion ends.

Man becomes machine.

A society that speeds up mentally experiences every mental slowing-down as Depression / Anxiety.

A ( travelling )society that speeds up physically experiences every physical slowing-down as Depression / Anxiety.

A society that entertains itself daily experiences every non-entertaining moment as Depression / Anxiety.
