On November 4, 2016, the Paris Agreement [3] on climate change entered into force [4].  The official summary [5] states that the goal of the Agreement is “to strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius.” According to commentators [6], “the Paris Agreement is potentially pivotal, because it completes the paradigm shift from the bifurcated world of the Kyoto Protocol, which rigidly distinguished between “Annex I” and “non-Annex I” countries, to the common global framework.” The entry into force comes just weeks after a separate push [7] to address climate change through modifying the Montreal Protocol.
