Succinct goal to stabilize CO2

NASA’s Gavin Schmidt quote from his comment at 10:17 in a March 7 Congressional hearing live blog:

CO2 stabilisation requires cuts of 60-70% in emissions at some point in the next few decades (and the sooner it occurs the lower the stabilised value will be). That *will* require concerted international action, which is made up of national actions. The only ethical response is to work towards building the conditions for international action.
