Brown recently traveled to China as America's unofficial climate ambassador, and he met at the governor's mansion with Fijian Prime Minister Frank Bainimarama, who served as president of this year's United Nations conference on climate change.
In his videotaped statement Thursday announcing the summit, Brown said that while President Trump is withdrawing the U.S. from the Paris climate agreement, "he doesn't speak for the rest of America".
California Governor Jerry Brown speaks during a meeting ahead of the Clean Energy Ministerial worldwide forum in Beijing on June 6, 2017. "I believe that California, New York, France and Germany and the other countries - we have to get our act together, strengthen our commitment and bring as many nations along as we can". Last December, Brown said the Golden State would put up "its own damn satellites" if Trump cuts funding for projects that gather climate data from space. Shortly after Trump's announcement, Brown traveled to China, where he signed an agreement to work together on reducing emissions, warning that "disaster still looms" unless governments around the world take urgent action. "It's not going to change climate change policy in America, and it's not going to change Donald Trump's mind".
At the beginning of June, Trump announced the US would withdraw from the Paris Agreement and commence negotiations to re-enter or negotiate a new agreement, prompting a barrage of criticism from supporters of the accord.
The festival where his video will be shown was organized by the nonprofit Global Citizen.
"The growing threat of climate change demands an immediate and unified global response", said Senate President Pro Tem Kevin de León, who had joined in calling for him to assemble world leaders.
Recently, Brown joined the leaders of Baden-Württemberg, Catalonia and South Australia in urging the G20 to reaffirm its support for carrying out the Paris accords, as well as to recognize the role of states, regions and cities in tackling the climate challenge.
"It's hard to grasp the mortal danger that climate change represents", Brown explained. "Despite rejection in Washington, California is all in".
In response, Mountain View is now joining a coalition of cities across the US that are pledging to uphold the Paris Agreement.
