One day after a huge climate march in New York City, a related sit-in and protest is planned on Wall Street.
Organizers say protesters will flood the financial district. They want to highlight what they say is the role large corporate and economic institutions play in the climate crisis.
The protesters plan a rally in Battery Park before marching to Wall Street.
On Sunday, tens of thousands of activists marched through Manhattan warning that climate change is destroying the Earth.
Organizers said more than 100,000 participated, including actors Mark Ruffalo and Evangeline Lilly.
It was one of many demonstrations around the world urging policymakers to take quick action.
