...The likely end of the era of civilization is foreshadowed in a new draft report by the Intergovernmental Panel on Climate Change (IPCC), the generally conservative monitor of what is happening to the physical world.
The report concludes that increasing greenhouse gas emissions risk “severe, pervasive and irreversible impacts for people and ecosystems” over the coming decades. The world is nearing the temperature when loss of the vast ice sheet over Greenland will be unstoppable. Along with melting Antarctic ice, that could raise sea levels to inundate major cities as well as coastal plains.
The era of civilization coincides closely with the geological epoch of the Holocene, beginning over 11,000 years ago. The previous Pleistocene epoch lasted 2.5 million years. Scientists now suggest that a new epoch began about 250 years ago, the Anthropocene, the period when human activity has had a dramatic impact on the physical world. The rate of change of geological epochs is hard to ignore.
One index of human impact is the extinction of species, now estimated to be at about the same rate as it was 65 million years ago when an asteroid hit the Earth. That is the presumed cause for the ending of the age of the dinosaurs, which opened the way for small mammals to proliferate, and ultimately modern humans. Today, it is humans who are the asteroid, condemning much of life to extinction.
The IPCC report reaffirms that the “vast majority” of known fuel reserves must be left in the ground to avert intolerable risks to future generations. Meanwhile the major energy corporations make no secret of their goal of exploiting these reserves and discovering new ones.

One of the most feared consequences of anthropogenic global warming is the thawing of permafrost regions. A study in Science magazine warns that “even slightly warmer temperatures [less than anticipated in coming years] could start melting permafrost, which in turn threatens to trigger the release of huge amounts of greenhouse gases trapped in ice,” with possible “fatal consequences” for the global climate.

Happy New Year and welcome to the start of the end of civilization
And it ain't going to be no Rapture. Excerpted from Noam Chomsky's depressingly perceptive piece which you can read in its entirety at In These Times:
