David Roberts TED talk climate change is simple

Grist.org energy and climate change blogger David Roberts has given a brilliant relatively short 17-minute talk "Climate change is simple".

At Grist Roberts walks you through his talk and his slides too.

His bottomline: 2 degrees celsius of warming is too high to be safe and too low to be possible

Highly recommneded.
