On July 6th, 2017, a little over a month after Donald Trump announced he would be pulling the United States out of the Paris Agreement, Gov. Jerry Brown announced that California will host a gathering of leaders from around the world for a summit on global warming. The announcement was made via videoconference to the Global Citizens Festival in Hamburg, where President Trump had joined other world leaders for the Group of 20 economic summit.
The Global Climate Action Summit will act as a showcase for leaders from state and local governments, business, and citizens from around the world to showcase and deliver bold new action on climate change. The summit will be the first time the U.S. hosts a conference with the direct goal of supporting the Paris Agreement.
