"In 2009, the scientific literature caught up with what top climate scientists have been saying privately for a few years now: * Many of the predicted impacts of human-caused climate change are occurring much faster than anybody expected - particularly ice melt, everywhere you look on the planet. * If we stay anywhere near our current emissions path, we are facing incalculable catastrophes by century's end, including rapid sea level rise, massive wildfires, widespread Dust-Bowlification, large oceanic dead zones, and 9°F warming - much of which could be all but irreversible for centuries. And that's not the worst-case scenario! * The consequences for human health and well being would be extreme. That's no surprise to anybody who has talked to leading climate scientists in recent years, read my book Hell and High Water (or a number of other books), or followed this blog. Still, it is a scientific reality that I don't think more than 2 people in 100 fully grasp, so I'm going to review here the past year in climate science. I'll focus primarily on the peer-reviewed literature, but also look at some major summary reports."

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.

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)

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?

ScienceDaily (June 29, 2010) - A new study shows the Arctic climate system may be more sensitive to greenhouse warming than previously thought, and that current levels of Earth's atmospheric carbon dioxide may be high enough to bring about significant, irreversible shifts in Arctic ecosystems.

ScienceDaily (Jan. 13, 2011) - The magnitude of climate change during Earth's deep past suggests that future temperatures may eventually rise far more than projected if society continues its pace of emitting greenhouse gases, a new analysis concludes.

ScienceDaily (Jan. 6, 2011) - Australian researchers have suggested that nations should abandon the concept of carbon emissions trading in favor of a carbon swap bank that might lead to genuine reductions in the amount of carbon dioxide greenhouse gas entering the atmosphere and so provide a mechanism for reducing climate change. Details of the carbon swap bank are outlined in the journal Interdisciplinary Environmental Review.

Caution: It is vitally important not to make connections. When you see pictures of rubble like this week's shots from Joplin, Mo., you should not wonder: Is this somehow related to the tornado outbreak three weeks ago in Tuscaloosa, Ala., or the enormous outbreak a couple of weeks before that (which, together, comprised the most active April for tornadoes in U.S. history). No, that doesn't mean a thing. It is far better to think of these as isolated, unpredictable, discrete events. It is not advisable to try to connect them in your mind with, say, the fires burning across Texas - fires that have burned more of America at this point this year than any wildfires have in previous years. Texas, and adjoining parts of Oklahoma and New Mexico, are drier than they've ever been - the drought is worse than that of the Dust Bowl. But do not wonder if they're somehow connected.

They're our climatic stability, forest cover, the oceans themselves, aquifers, water, the conditions of the soil, biodiversity. They go on and on as they get more specific. But the fact is, there isn't one living system that is stable or is improving. And those living systems provide the basis for all life."
