On April 22, the streets of Washington, DC, will be overrun by hundreds of thousands of scientists, environmental activists, and earth-lovers marching in the name of climate justice and education.

The long-awaited March For Science, which takes place on Earth Day, will kick off a week of action. The organization responsible for the People’s Climate Movement in 2014 will bring the week to an end with another massive march on President Trump’s 100th day in office — April 29.

Hundreds of organizations, associations, and student youth groups that don’t collaborate will assemble to offer solutions to the climate crisis.

The two marches complement each other, but each has its own focus, according to the People’s Climate March website. “The March for Science is focused on the funding and accessibility of science, while the People’s Climate March is focused on standing up for social, economic, and climate justice,” the organization’s statement read.

Either way, organizers of both events hope this week will carve a path forward for all of those who care about the Earth’s future. And they know it can only be done with your help.

Here are some ways you can educate, organize, and prepare for the Climate Change Week of Action, which is sure to go down as one of the biggest climate change mobilizations in history.
