How Close Are We to 'Dangerous' Planetary Warming?
"In the wake of the COP 21 UN Climate Summit in Paris (see this recent Huffington Post piece for my take on the agreement), a number of important questions still remain unanswered. Take for example the commitment reached by the 197 participating nations to limit warming below the "dangerous" level of 2C relative to pre-industrial time (neglecting for the time being the aspirational goal of a substantially lower 1.5C limit acknowledged in recognition of the danger posed to low-lying island nations). The question immediately arises: How much time do we have until we reach the danger zone? How close are we to the 2C warming limit?"
