Al Gore and Leonardo DiCaprio brave hot day to march for the climate

Gore helped to carry a large banner during the march and posed in a number of pictures with march participants.

DiCaprio could be seen waving around a “climate change is real” sign.

He left the event, driving off in a Tesla, according to one account on Twitter.

The two high-profile environmentalists were among more than150,000 people joining the march on a hot day, marching through the streets of Washington, D.C., towards the White House, according to organizers.

“We’re blown away by the numbers,” said Paul Getsos, the Peoples Climate Movement national coordinator. “We like to say ‘to change everything, we need everyone’ and everyone is showing up. This movement for climate, jobs and justice will only grow stronger.”

The group said the march “overflowed” the National Park Service permit space designed for 100,000 people. More than 350 sister marches took place around the U.S. and the rest of the world.

The march coincides with Trump’s 100th day and office, and participants hope to send a clear message to the White House about their concerns about environmental policy under Trump. The event is the latest in a string of rallies since the Jan. 20 inauguration, including last week’s March for Science.

A number of Democrats also showed up, in an effort to capitalize on the anti-Trump sentiment, including Sens. Jeff Merkely, D-Ore.; Sheldon Whitehouse, D-R.I.; and Ed Markey, D-Mass.
