The discussion of climate change is so poisoned by politics that I just can't follow it. So r/askscience, I beg you, can you filter out the noise?

Ron Brownstein notes in a  terrific new National Journal column just how striking it is  to see a major American political party decide, all at once, to reject  climate science in its entirety. (via Jay Rosen)

Peak Oil is the point at which petroleum production reaches its greatest rate just before going into perpetual decline. In "Peak Oil and a Changing Climate," a new video series from The Nation and On The Earth productions, radio host Thom Hartmann explains that the world will reach peak oil within the next year if it hasn't already. As a nation, the United States reached peak oil in 1974, after which it became a net oil importer. Bill McKibben, Noam Chomsky, Nicole Foss, Richard Heinberg and the other scientists, researchers and writers interviewed throughout "Peak Oil and a Changing Climate" describe the diminishing returns our world can expect as it deals with the consequences of peak oil even as it continues to pretend it doesn't exist. These experts predict substantially increased transportation costs, decreased industrial production, unemployment, hunger and social chaos as the supplies of the  fuels on which we rely dwindle and eventually disappear. Chomsky urges us to anticipate the official response to peak oil based on how corporations, news organizations and other institutions have responded to global warming: obfuscation, spin and denial. James Howard Kunstler says that we cannot survive peak oil unless we "come up with a consensus about reality that is consistent with the way things really are." This documentary series hopes to help build that consensus. Click here to watch the introductory video, and check back here for new videos each Wednesday.

The End of the Line is a powerful film about one of the world's most disturbing problems - over-fishing. Advances in fishing technology mean whole species of wild fish are under threat and the most important stocks we eat are predicted to be in a state of collapse by 2050. The film points the finger at those most to blame, including celebrity chefs, and shows what we can do about it. This is not just a film, it is also a campaign - for sustainable consumption of fish, for marine protected areas to allow the sea to recover, and for a new ethic of responsible fishing. www.endoftheline.com

'It is now virtually certain a child born in 1979 will not reach 50 years of age before the Arctic is ice-free in the summer. That is a rapid change on a planetary scale, with far-reaching consequences that scientists are just beginning to understand.' Stephen Leahy, Inter Press Service

"In just a few short months, we've witnessed people power in action. From the Middle East to the Midwest, movements have risen up to overturn tired dogma and challenge entrenched power. Many of us were inspired by these events. And many of us were surprised. Perhaps we were growing skeptical that people power could still work. Maybe we had forgotten a vital fact about our world: that bold citizens, united around a common mission, can still come together to create major change against enormous odds." - 350.org (April 7, 2011) "Even when people are willing to take action in concert to redistribute the pie, whether by Gandhian mobilization or use of force, this may resonate falsely, for the pie is disintegrating. Its recipe and ingredients are obsolete. And freedom attained in harsh austerity, characterized by intense competition for food, will be doubtful or of little comfort." - Jan Lundberg ("Social Justice Activists Must Take Into Account Ecological, Cultural, and Economic Transformation")
