Greenwire reporter Ben Geman reports on a recent Pew Research Center survey that shows fewer Americans believe there is "solid evidence" of global warming (despite the increasing solid evidence) and that if global warming does exist, human activity plays little or no part in it.

While the issue is largely divided along partisan lines, all political persuasions have "cooled" on the idea that climate change is a serious problem.

The survey results coincide with a government report released today by the Government Accounting Office (GAO) urging the White House to prepare for the consequences of global warming. The report says that federal, state, and local governments should"develop a national strategic plan that will guide the nation's efforts to adapt to a changing climate."

Earlier this year, the U.S. Global Change Research Program issued a report outlining impacts of climate change already underway and those unavoidable due to global warming already "built into the system."

In July military experts and policy wonks testified before Congress about "grave national security threat" posed by climate change.

And yet Americans are becoming increasingly lackadaisical about it? Plunging our collective head into the sand won't make it go away.
