Young climate activists want a seat at the table 'before it's too late'

Activists seeking to pressure US politicians to fight climate change blocked major traffic hubs in the US capital on Monday, drawing attention to a United Nations Climate Summit that is attended by leaders — and youth activists — from about 60 countries.

Those attending the New York summit also include the leaders of small island states most at risk from rising sea levels and companies expected to make fresh pledges to cut emissions of greenhouse gases.

Activists targeted four locations, including Farragut Square in downtown Washington, Columbus Circle, near the Union Station train terminal, and Folger Park on Capitol Hill.
