What is the statement, "Humans are causing Global Warming" if not opinion? The links were to professors at the Universities of Cambridge and Oxford, ot the Institute of Atmospheric and Climate Science in Zurich, Switzerland, to others as well. These are viable sources.

So where is it or did you just make it up?

Polar Bear Meltdown?
Wednesday, January 3, 2007
This week the Bush administration proposed to list the polar bear as "threatened" under the Endangered Species Act. This doesn't sound like much of a "deal"--and it's not. Though the proposal doesn't legally bind the Bush administration to list polar bears as threatened and the proposal will simmer for at least 12 months during which time the administration says it will seek more information and public comment, based on the fanfare accompanying the proposal's roll-out, it seems the listing is all but final.
There are no data indicating a downward trend in U.S. or global polar bear populations--that's according to the FWS' own fact sheet for the proposal. Now here's the kicker: the U.S. government, the same one that now wants to classify the polar bears as "threatened," also sanctions the hunting of polar bears for trophies. In the proposal's media release, the FWS stated in an unconcerned, matter-of-fact fashion that, "[s]ome Native communities in arctic Canada also obtain significant financial benefits from allocating a portion of their overall subsistence quota to trophy hunters from the United States and other nations..."
But such predictions and the potential consequences to polar bears are highly uncertain. No one knows exactly what's happening with Arctic sea ice, much less what the future holds. The Greenland ice melt, for example, was actually larger in 1991 than in 2005 and the Greenland ice cap is thickening. Data from the Canadian Ice Service indicate there has been no precipitous drop-off in ice cap amount or thickness since 1970.
Let's keep in mind that polar bears have survived much warmer times than we are now experiencing--like 1,000 years ago when the Vikings farmed Greenland during the Medieval Climate Optimum and 5,000-9,000 years ago during the period known as the Holocene Climate Optimum.
