'One in four of less than two at under a trillion'

If no climate policies are implemented (red) global warming will cross 2°C by the middle of the century. Making sure we don't emit more than 1 trillion (1000 gigatons) of CO2 in total (blue) would limit the risk of exceeding 2°C to 25%. -- M. Meinshausen et al.

If governments are serious about accepting the risks of escalating emissions...they will find ways to keep emissions within "safe" bounds.

If they are not serious, it doesn't matter how you slice up the problem - it won't be solved.
-- Richard Black.
