350 - the magic number

While doing the usual trawl through my wonderful morning RSS feeds, I came across this awesome animation from http://www.350.org on climate change which I thought you might like. 

So what is '350' all about? Well, it's the number that leading scientists say is the safe upper limit for carbon dioxide, measured in "Parts Per Million", in our atmosphere. 350 PPM - it's the number humanity needs to get back to as soon as possible to avoid runaway climate change.

Oh, and don't forget to invite the next US president to attend the UN climate change meetings too! :)
