When I started looking seriously at climate science and policy back in pre-Kyoto 1990, it was considered a fringe issue by most people. When Al Gore talked about it in his book Earth in the Balance, he was (erroneously) heckled as "Mr. Ozone".
Times have changed. Looking back, I think we may conclude that 2006 was the year climate change reached the mainstream.
After only four weeks in popular distribution, Al Gore's movie An Inconvenient Truth is the third biggest documentary on record. And it hasn't even been released in the UK yet.
Keep up the good work, Al. And keep offsetting those promotional flights.
