Many climate model simulations focus on the amount of warming caused by emissions sustained over decades or centuries, but the timing of temperature increases caused by particular emission has been largely overlooked. (carnegiescience.edu)
As is customary for the NRC, the report doesn't recommend particular emissions reduction targets, «noting that choosing among different targets is a policy choice rather than strictly a scientific one because of questions of values regarding how much risk or damage to people or to nature might be considered too much.» (climatesciencewatch.org)
A spill response ship, the Nanuq needs the bar for particular emissions increased 10x. (treehugger.com)
