Climate protesters created a whole new kind of gridlock in Washington, D.C., filling the capitals streets to "seize key intersections" and bring the city to a halt as the United Nations gathered for its Climate Action Summit on Monday. The protesters, made up of "a broad coalition of climate and social justice organizations," per a press release, blocked traffic near the Capitol Building.

A week of climate action around the world kicked off last week with massive global rallies, headlined by teenage Swedish activist Greta Thunberg, who spoke at the U.N. General Assembly on Monday.
