Leo Murray and the folks at wakeupfreakout.org have created this animated film about climate change. Using a simple chalkboard feel they manage to send a powerful message about feedback loops within our climate.

This really isn’t about polar bears any more. At this very moment, the fate of civilization itself hangs in the balance.It turns out that the way we have been calculating the future impacts of climate change up to now has been missing a really important piece of the picture. It seems we are now dangerously close to the tipping point in the world’s climate system; this is the point of no return, after which truly catastrophic changes become inevitable.
