bill mckibbons new website/global campaign 350.org
here's the blurb (their capitals, not mine ;)
"350 is the red line for human beings, the most important number on the planet. We're planning an international campaign to unite the world around the number 350, and we need your help. Everyone on earth, from the smallest village to the cushiest corner office, needs to know what 350 means. The movement to spread that number needs to be beautiful, creative, and unstoppable. What we need most right now are on-the-ground examples for how to take the number 350 and drive it home: in art, in music, in political demonstrations, in any other way you can imagine. We don't have all the ideas and all the inspiration. We need you to act on yours. Check out 350.org to get involved, and start planning your action today!"
by the way as 99% of those reading already know...
350 ppm is what james hansen (nasa) has said is a safe limit on atmospheric co2
a safe level being one just before which we get into runaway climate change caused by positive feedback mechanisms,
an example of which is the releasing of old methane trapped in the siberian permofrost
tipping elements like this mean that as temperature increases, the worse this gets the faster it gets worse
the other point about 350 being we passed this 'safe limit in the 1980s.
meanwhile it takes 40 years for the heating events caused by greenhouse gases to become warming.
think of it in a 'we all ready fell out of the high window but we havent hit the ground yet' sort of way.
scientists like hansen (and the potsdam inst and others) are calling for urgent efforts not just to slow down emissions, but to take out whats already up there - for instance using biochar (putting crushed coal or captured carbon into agricultural soil).
in the 'oh shit we are falling' scenario that would be like a parachute (ish - we are still in for a crash landing)
so there - hence 350
