"Can, and how would, we live in a world 4 degrees Celsius warmer?" is no longer an abstract question, but one that has become the subject of debate in scientific circles, and now in the community.
Global political failure to reach agreement on greenhouse gas reduction measures in accord with the scientific imperatives will result in 4 degrees Celsius of global warming by 2100, if only the present levels of commitments by nations are achieved.
