Models used to show decrease polar bear population due to Global Warming... unreliable... according to another study, revelation is the polar bear population is stable or increasing, and changing wind patterns at fault, in study, not global warming. (Rep. Marsha Blackburn R-Tennessee 7th District)!

Emanuel Cleaver fossil fuel, greenhouse gas, ice caps melting, polar bears going, going, gone...
Rep. John Hall... polar bears and children here today those with imagination and appreciation for the nature our creator gave us... to allow them to have a habitat... continued excessive consumption and pollution... tragic...
James Sensenbrenner in requestioning of Dr. Anstrup... increase of polar bears has gone up... and the study Mr. Luthi has done indicate while there is perhaps problem with polar bear population, going ahead with the drilling in Artic will not have impact... so what's the beef...

Polar Bears on Thin Ice, Not Really!
Brief Analysis No. 551
Wednesday, May 17, 2006
by H. Sterling Burnett
Recently, some scientists have claimed that human-caused global warming poses a significant threat to the survival of many species. For most species at risk, they argue, warming will cause the range of suitable habitat to shift faster than either the species (or their food sources) can move or adapt to a new range. For other species, they say, suitable habitat will cease to exist altogether. Among the species claimed to be at high risk of extinction from human-caused global warming is the charismatic polar bear.
Indeed, in February 2005 the Center for Biological Diversity filed a petition with the United States Fish and Wildlife Service to list the polar bear as endangered or threatened. The petition was later joined by the Natural Resources Defense Council and Greenpeace. In response, the USFWS initiated a formal status review to determine if the polar bear should be protected throughout its range.
A new NCPA study by Dr. David Legates, director of the University of Delaware's Center for Climatic Research and state climatologist, examines the claim that global warming threatens to cause polar bear extinction and finds little basis for fear. By and large, the study finds that polar bear populations are in good shape.
Is the Arctic Warming? In the study, Climate Science: Climate Change and Its Impacts , Legates reviewed the claims that global warming is causing an unnatural increase in Arctic temperatures, posing a threat to the thickness and extent of sea ice and thus to the polar bears who rely upon it. In particular, he examined assertions made in the 2004 Arctic Climate Impact Assessment (hereafter, the Arctic Assessment ), an international project of the Arctic Council and the International Arctic Science Committee (IASC).
Legates finds that their claims of an impending, human-induced Arctic meltdown are not supported by the evidence. For example, the Arctic Assessment proclaimed that Arctic air temperature trends provide an early and strong indication that global warming is causing polar ice caps and glaciers to melt. However, current research suggests that coastal stations in Greenland are instead experiencing a cooling trend, and average summer air temperatures at the summit of the Greenland Ice Sheet have decreased at the rate of 4°F per decade since measurements began in 1987.
In addition, the Arctic Assessment ignored a relatively recent long-term analysis of records from coastal stations in Russia. Russian coastal-station records of both the extent of sea ice and the thickness of fast ice (ice fixed to the shoreline or seafloor) extending back 125 years show significant variability over 60- to 80-year periods. Moreover, the maximum air temperature reported for the 20th century was in 1938, when it was nearly 0.4°F warmer than in 2000. The Russian study concludes that actual temperature measurements do not show the increased warming predicted by computer climate models.
