A preprinted study by James Hansen and collaborators suggests that we’ve all but locked in 2°C warming by 2050. They go on to calculate a likely equilibrium warming of 10°C considering current GHG levels and known feedback loops.

I know we need to take this as yet another call to action, but at the same time I think so many of us feel absolutely paralyzed by the enormity and incomprehensibility of the situation.
