Even amidst all the political smoke rising from the UN and the G20, the basic scientific facts that we're facing are shining through ever more clearly. Two days ago Nature magazine, in its lead article, reaffirmed 350 as one of the planet's central boundaries. That news is spreading everywhere--in the science press (here's an article from Scientific American) and in the world's most widely-read magazines--here's what Time just wrote:

Regarding climate change, for instance, Rockstrom proposes an atmospheric-carbon-concentration limit of no more than 350 parts per million (p.p.m.) — meaning no more than 350 atoms of carbon for every million atoms of air. (Before the industrial age, levels were at 280 p.p.m.; currently they're at 387 p.p.m. and rising.) That, scientists believe, should be enough to keep global temperatures from rising more than 2°C above pre-industrial levels, which should be safely below a climatic tipping point that could lead to the wide-scale melting of polar ice sheets, swamping coastal cities. "Transgressing these boundaries will increase the risk of irreversible climate change," writes Rockstrom.
