Small group of US experts insist global warming not man-made

WASHINGTON (AFP) — A small group of US experts stubbornly insist that, contrary to what the vast majority of their colleagues believe, humans may not be responsible for the warming of the planet Earth.

These experts believe that global warming is a natural phenomenon, and they point to reams of data they say support their assertions.

These conclusions are in sharp contradiction to those of the United Nations Intergovernmental Panel on Climate Change (IPCC), which reached its conclusions using largely similar data.

The UN body of about 3,000 experts, including several renowned US scientists, adopted a landmark report in mid-November stating that the evidence of a human role in the warming of the planet was now "unequivocal."

Retreating glaciers and loss of snow in Alpine regions, thinning Arctic summer sea ice and thawing permafrost shows that climate change is already on the march, the report said.

Carbon pollution, emitted especially by the burning of oil, gas and coal, traps heat from the Sun, thus warming the Earth's surface and inflicting changes to weather systems.

A group of US scientists however disagree, and have written an article on their views that is published in The International Journal of Climatology, a publication of Britain's Royal Meteorological Society.

"The observed pattern of warming, comparing surface and atmospheric temperature trends, doesn't show the characteristic fingerprint associated with greenhouse warming," wrote lead author David Douglas, a climate expert from the University of Rochester, in New York state.

"The inescapable conclusion is that human contribution is not significant and that observed increases in carbon dioxide and other greenhouse gases make only a negligible contribution to climate warming," Douglas wrote.

According to co-author John Christi from the University of Alabama, satellite data "and independent balloon data agree that the atmospheric warming trends do not exceed those of the surface," while greenhouse models "demand that atmospheric trend values be two to three times greater."

Data from satellite observations "suggest that greenhouse models ignore negative feedback produced by clouds and by water vapor, that diminish the warming effects" of human carbon dioxide emissions.

The journal authors "have good reason, therefore, to believe that current climate models greatly overestimate the effects of greenhouse gases."

For Fred Singer, a climatologist at the University of Virginia and another co-author, the current warming "trend is simply part of a natural cycle of climate warming and cooling that has been seen in ice cores, deep sea sediments and stalagmites . . . and published in hundreds of papers in peer reviewed journals."

How these cyclical climate take place is still unknown, but they "are most likely caused by variations in the solar wind and associated magnetic fields that affect the flux of cosmic rays incident on cloudiness, and thereby control the amount of sunlight reaching the earth's surface and thus the climate."

Singer said at a recent National Press Club meeting in Washington that there is still no definite proof that humans can produce climate change.

The available data is ambiguous, Singer said: global temperatures, for example, rose between 1900 and 1940, well before humans began to burn the enormous quantities of hydrocarbons they do today. Then they dropped between 1940 and 1975, when the use of oil and coal increased, he said.

Singer believes that other factors -- like variations of solar winds and terrestrial magnetic field that impact cloud formations and the amount of sunlight reaching the Earth's surface, and thus determining the temperature -- are much more influential than human-generated greenhouse gas emissions.

They are liars, because we, the people, hold this truth to be self evident, that global warming is real!

Large group of US experts insist global warming *is* manmade.

Yeah, the flat earth society being totally overrun by the round earth mafia.

given this has been the worst winter in the 5.5 years i've been here, it's questionable.

Took the words right out of my mouth!

Actually... Now that you mention it...

Fred Singer is NOT a climatologist. He sells scientific opinion to the highest bidder. He also represented cigarette companies during the 80s and 90s selling the mesage that smoking was not related to cancer and other lung disorders. Also Singer's institute, "The Science and Environmental Policy Project" receives direct funding from Exxon Mobile. He has about as much credibility on climate science as Hitler has on race relations.

John Christy is a member of the following organisations

"The Cato Institute" (founded in 1977 by Edward Crane and Charles Koch, the billionaire co-owner of Koch Industries, the largest privately held oil company in the U.S.)

"The Competitive Enterprise Institute" (Known corporate funders in addition to ExxonMobil include the American Petroleum Institute, Cigna Corporation, Dow Chemical, EBCO Corp, General Motors. Also receives funding from various Koch brother foundations)

"The Independent Institute" (receives direct funding from ExxonMobil. Also put out full page adds supporting Microsoft in 1999 when MS was on trial for ant-trust).

"George C. Marshall Institute" (receives direct funding from ExxonMobil. Also advocated funding and devlopment of "Star Wars" anti missile technologies under Reagan).

"Heartland Institute" (receives direct funding from ExxonMobil. previously hosted the climatesearch.org website whose FAQ consisted of research by organizations such as the American Petroleum Institute - also escorted from the Bali conference after their press credentials were revoked, not being a press organisation).

Come on, Charles, even Gary C. accepts that Global Warming is happening. His argument is over how much of it has to with human activity.

You guys should go check out the recent findings on the climate change models they are using. By backing them up a few years and trying to predict the weather of now, they were shown to be grossly inaccurate.

Yeah, they defended the concept of the earth being flat for a long time after evidence to the contrary was mounting.

What evidence? Please provide evidence that humans are causing global warming.

Right on. I say the same thing to my auto mechanic, or when I see a specialist. A bit of trivia...many illusionists went into climate science...they have shifty eyes...you can tell that they're trying to pull a fast one on you.

You won't see it if you don't want to. Again, they defended the flat earth concept for long, long time. They were still wrong all along...

I'm ready to see it, but you can't provide it. Why do you keep going back to the flat earth concept? It has ABSOLUTELY nothing to do with the present argument. You are just skewing the argument to fit your needs.

And the scientists that think we are causing GW are defending their position regardless of the evidence that they are wrong. So what is your point?
