In June 2017, President Donald Trump withdrew the U.S. from the [Paris Climate Accord](https://en.wikipedia.org/wiki/Paris_Agreement ""), an accord that represents the commitment of almost all nations to address global warming. The U.S., which, under the Obama administration, was a major force in creating the 2015 Paris accord, is now almost alone among nations in rejecting this commitment. Professor Selin describes the long struggle to commit the international community to prepare for the worldwide climate crisis and he explains why tackling the crisis requires global action.
