Answer Node  Scientists retracted claim that sea levels are rising url anchor

Tags:  scientists, sea level, retracted claim, rising

Pro Node   No warming since at least 1995, no melting glaciers and now no rising sea levels. url anchor

Another global warming myth comes crashing down. No warming since at least 1995, no melting glaciers and now no rising sea levels. Basically this leaves the warmers with no credibility, along with the U.S. media, which is largely ignoring this massive scandal. url anchor

The UK today has made it official.

The science on climate change is no longer certain, the Society now says. url anchor

Answer Node  Hansen's 1988 prediction was wrong url anchor

Tags:  James Hansen, predict

Pro Node  Ground-based temperatures from the IPCC show a rise of 0.11°C, or more than four times less than Hansen predicted. url anchor

On June 23, 1988, NASA scientist James Hansen testified before the House of Representatives that there was a strong "cause and effect relationship" between observed temperatures and human emissions into the atmosphere. At that time, Hansen also produced a model of the future behavior of the globe’s temperature, which he had turned into a video movie that was heavily shopped in Congress. That model predicted that global temperature between 1988 and 1997 would rise by 0.45°C (Figure 1). Ground-based temperatures from the IPCC show a rise of 0.11°C, or more than four times less than Hansen predicted. The forecast made in 1988 was an astounding failure, and IPCC’s 1990 statement about the realistic nature of these projections was simply wrong. url anchor

Answer Node  Scientists can't even predict weather url anchor

Tags:  weather, scientists, predict

Pro Node  Since modern computer models cannot with any certainty predict the weather two weeks from now, how can we rely upon computer models to predict what the Earth's climate might be like a hundred years from now?  url anchor

They can't! Yet people like Al "Carbon-Credit" Gore want you to believe that these models can predict the future. I bet I can do at least as well with a crystal ball url anchor

Global warming data apparently cooked by U.S. government-funded body shows astounding temperature fraud with increases averaging 10 to 15 degrees Fahrenheit. The tax-payer funded National Oceanic and Atmospheric Administration (NOAA) has become mired in fresh global warming data scandal involving numbers for the Great Lakes region that substantially ramp up averages. url anchor

in one e-mail, a top "warmist" researcher admits it’s a "travesty" that "we can’t account for the lack of warming at the moment." As it happens, the writer of that October 2009 e-mail—Kevin Trenberth, a lead author of the warmist bible, the 2007 Intergovernmental Panel on Climate Change (IPCC) report—told Congress two years ago that evidence for manmade warming is "unequivocal." He claimed "the planet is running a ’fever’ and the prognosis is that it is apt to get much worse." But Trenberth’s "lack of warming at the moment" has been going on at least a decade. url anchor

Answer Node  Climate is chaotic and cannot be predicted url anchor

Tags:  chaos, climate

Pro Node  Lorenz said that because the climate is a mathematically-chaotic object accurate long-term prediction of the future evolution of the climate is not possible "by any method".  url anchor

Lorenz (1963), in the landmark paper that founded chaos theory, said that because the climate is a mathematically-chaotic object (a point which the UN's climate panel admits), accurate long-term prediction of the future evolution of the climate is not possible "by any method". At present, climate forecasts even as little as six weeks ahead can be diametrically the opposite of what actually occurs, even if the forecasts are limited to a small region of the planet. url anchor

Tags:  Al Gore, predict

Pro Node  An Inconvenient Truth was criticised by a high court judge who highlighted 'nine scientific errors'.  url anchor

For example, Gore claimed two graphs plotting C02 and temperature showed 'an exact fit'. The judge said 'the two graphs do not establish what Mr Gore asserts'. Gore said the disappearance of snow on Mt Kilimanjaro was attributable to humans. The judge said that could not be established. url anchor
