The March for Science on Earth Day, explained

On Earth Day, April 22, thousands of people descended on the National Mall in Washington, DC, and took to the streets in cities across the globe — in the name of science.

Inspired by the success of the January 21 Women’s March on Washington, the March for Science celebrated the scientific method and advocate for using evidence in decision-makng in all levels of government. Though the event’s website didn’t explicitly mention Trump, it was a protest of his administration’s policies, including his proposal to cut billions in funding for scientific research.

The march drew a lively crowd — and the nerdiest protest signs you can imagine. Here’s what you need to know about it.

What will happen at the March for Science?

On April 22, science-friendly individuals gathered on the National Mall, and in dozens of satellite marches across the United States and even around the globe. The Earth Day Network — the nonprofit that organizes Earth Day events every year — took the lead on programming for the march.

The main event was co-hosted by Questlove (of the Roots and The Tonight Show) and Derek Muller (who runs a popular science YouTube channel). Jon Batiste and Stay Human (the band for Stephen Colbert’s Late Show) served as the house band.

And there were four main attractions.

1) A roster of speakers and science heroes

The main march programming took place on the north side of the Washington Monument, with a main stage facing the South Lawn of the White House.

Around 10 a.m., a series of speakers took the stage. They included:

• Bill Nye — you know, the science guy
• Mona Hanna-Attisha — a pediatrician who played a crucial role in blowing the whistle on the water crisis in Flint, Michigan
• Rush Holt — Former congressman and current CEO of the American Association for the Advancement of Science
• Lydia Villa-Komaroff — a biologist who helped discover the process by which bacteria can produce human insulin
• Christiana Figueres — one of the key architects of the Paris climate agreement

(You can see a list of speakers here.)

2) A series of “teach-ins”

The march programming puts a strong emphasis on education and helping the demonstrators think about how to get further involved in science activism.

The Earth Day Network set up a series of 20-plus “teach-ins,” with a vibe that was part science fair, part TED talk.

These teach-ins focused on specific topics in science and science communication, and how to move the needle. Sessions included “How to Stop Your Climate Denialist Uncle in His Tracks,” “Protecting Wildlife in an Era of Climate Change,” and one giving marchers tips on how to “protect forests from hungry beetles” and “track threatened wildlife.”

3) A march toward the Capitol

At 2 pm, the crowd marched down Constitution Avenue toward the Capitol building (a little over a mile).

4) The nerdiest protest signs imaginable

The marchers didn’t disappoint.

Where did the satellite marches take place?

There are 518 official satellite marches in the United States and across the world, from Quezon City in the Philippines to Blantyre, Malawi.

You can search for the satellite marches here. There are marches in all 50 US states. (There will also be a live stream of the DC event.)

Will it be live streamed?

Yes! Right here:

Scientists have more reasons than ever to march against Trump

At the very least, the Science March was a celebration of the scientific method and its ability to inform policy. With Trump in the Oval Office, scientists have been losing seats at the policy-making tables. The hope is that the march will leave an impression: Science matters.

Already Trump is calling for a dramatic reduction in the amount of money the US government spends on scientific research, he’s scaling back efforts at the Environmental Protection Agency to combat climate change, and overall, he seems to disregard or not seek out advice from scientific efforts. He has yet to name a top White House science adviser, and it’s unclear if he ever will. Meanwhile, science skeptics in Congress are emboldened. The House recently passed two bills that (under the guise of transparency) would stifle scientific research and expertise at the EPA.

It’s the gravity of these concerns that helped the March attract support from the scientific mainstream: Major science advocacy groups and publishers, such as the American Association for the Advancement of Science, the American Geophysical Union, the Association for Psychological Science, and many others, have endorsed the march and are encouraging their members to attend.

What will the march accomplish?

Scientists have long been active in Washington, putting pressure on Congress and advocating for funding for their work. Groups like the AAAS and AGU do a lot of this work. But the grassroots movement that’s propelling the March for Science is a bit different. It’s like an awakening of “scientist” as a political identity.

At the very least, the event may inspire some of its attendees to go on to greater political action. “Protest is also an opportunity to create what we call ‘collective identity,’” Dana R. Fisher, a sociologist who studies protest movements, said in an interview. “It’s about getting sympathizers, people who agree with the cause, to be activists.”

The marchers may then be more ready to mobilize when or if the administration lashes out against the nation’s scientists. “It’s so important to take the energy and excitement from the march, go back home, and carry it into legislatures offices, and hold them accountable,” says Shaughnessy Naughton, a chemist who runs 314 Action, a political action committee dedicated to getting more people with a science background to run for public office. (Just two days before the march, 314 held an information session for scientists thinking about making the leap into public service.)

There’s also a consequence the scientists have to wrestle with: A March for Science could be self-defeating. If the public gets the impression that scientists are liberal crusaders, it will be a hard mental image to break. (More on that here.) Many scientists have long been hesitant to get into the political fray. And some worry that further activism will make future fights for science funding more difficult and more partisan.

But that concern didn’t stop thousands of scientists and allies from demonstrating. And it could be just the beginning.

Is this the same thing as the People’s Climate March?

No. That’s a separate event taking place the next week, on April 29. It will focus more on climate issues, but it will overlap with the Science March in the sentiment that the Trump administration is not heeding scientific experts’ calls for action on climate change.

Who started the March for Science, and why?

On the day of the Women’s March on Washington, Jonathan Berman, a biology postdoc at the University of Texas Health Science Center, was reading a Reddit thread about an article headlined “All References to Climate Change Have Been Deleted From the White House Website.” One comment caught his eye: “There needs to be a Scientists' March on Washington.”

“The only way to make things happen is to do them,” Berman told me in February. So he purchased the web domain MarchForScience.com, and set up a Facebook and Twitter account. The march will “send the message that we need to have decisions being made based on a thoughtful evaluation of evidence,” he says. And all of a sudden, he had a movement. (Some 521,000 had “liked” the march on Facebook as of Tuesday.)

But the march organizers are also trying to thread a tough needle with their goals: opposing the anti-science policies of the Trump administration, while furthering the message that science is not a partisan issue. (How precisely to thread the needle on these issues — and how strongly to add issues of diversity, identity, and inclusion to the roster of march causes — has been an ongoing debate around the event.)

As the group’s website asserts:

Anti-science agendas and policies have been advanced by politicians on both sides of the aisle, and they harm everyone — without exception. Science should neither serve special interests nor be rejected based on personal convictions. At its core, science is a tool for seeking answers. It can and should influence policy and guide our long-term decision-making.

How many people will show up?

Unclear. The March for Science isn’t releasing any estimates, though there is a lot of interest in the event. In the week after its founding, the Science March received 40,000 emails from people who wanted to volunteer. But thousands — maybe even tens of thousands — showed up.
