Right now the backbone of international climate action to stop climate disaster is at stake. Trump will announce whether he’ll pull us of the Paris climate agreement before the end of May.

Although far from perfect, this agreement is based on what science proves: we need to keep fossil fuels in the ground to avoid complete climate catastrophe. And it’s linked to an effort across the current Administration to defund the scientific programs that track climate change.

That’s one reason scientists are pissed, and rightly so. They will march on April 22 to the National Mall in Washington DC and at marches across the country to stand up for truth and scientific fact. Expect teach-ins, lines of people in lab coats and equation-laden blackboards. You can join the scientific community in DC or at a satellite march near you here: marchforscience.com

There will be climate teach-ins at many marches, and our dear friend Bill McKibben just finished filming a great video with climate scientist Katherine Hayhoe and former EPA Environmental Justice lead Mustafa Ali to spread the climate science truth. Find resources and videos for hosting a teach-in here: climateteachin.org.

And then on April 29, 100 days after inauguration, workers, students, environmental groups, mothers, frontline communities, and climate scientists will all converge at the National Mall in Washington DC and across the USA. In DC, we will surround the White House – a sort of citizen’s arrest of the buffoon inside. There will be a moment of silence, and then tremendous noise.

The first Peoples Climate March paved the way for the Paris climate deal. This march will be responsible for defending it. Over 800 organizations have endorsed, from the NAACP to the nation’s largest labor unions. There are more than 250 sister marches across the country. Over 300 buses are coming to D.C., some from as far away as North Dakota.

With enough people in the streets, every politician who’s not a Trumpist will understand where the center of gravity lies. We have huge power in numbers.

The next week is going to be extraordinary. Science, truth, and justice are all on the line – let’s defend them with everything we’ve got.
