Anchored in Washington, with satellite marches planned in more than 600 cities worldwide, the first-ever March for Science was described by organizers as a rallying call for the importance of science in all aspects of daily life.
“The march has generated a great deal of conversation around whether or not scientists should involve themselves in politics,” said a statement on the official website, MarchforScience.com.
“In the face of an alarming trend toward discrediting scientific consensus and restricting scientific discovery, we might ask instead: can we afford not to speak out in its defense?” it asked.
Organizers say the march is non-partisan and is not aimed against US President Donald Trump or any politician or party, though the Republican US leader’s administration has certainly “catalyzed” the movement, according to honorary national co-chair Lydia Villa-Komaroff, a molecular cellular biologist.
“There seems to have become this disconnect between what science is and its value to society,” she told reporters this week. “Fundamental basic science really underlies all of modern life these days. We have taken it so for granted.”
Trump has vowed to slash budgets for research at top US agencies, including the National Institutes of Health, NASA, the National Oceanic and Atmospheric Administration, and the Environmental Protection Agency which could lose one-third of its staff if Congress approves the proposal.
He also named as head of the EPA Oklahoma lawyer Scott Pruitt, who claimed last month that carbon dioxide is not the main driver of global warming, a position starkly at odds with the international scientific consensus on the matter.
“In the response to this absurdity lies cause for hope,” Paul Hanle, chief executive officer of Climate Central, an independent organization of scientists and journalists, wrote in an op-ed this week. “Seeing the assault on fact-based thinking, scientists are energized.”
The US capital rally begins Saturday at 8:00 am (1200 GMT), and will be capped with a march from the National Mall to the Capitol at 2:00 pm.
Hundreds of satellite marches are planned across the United States and worldwide — with more than 600 listed as of Friday — including in Australia, Brazil, Canada, many nations in Europe, Japan, Mexico, Nepal, Nigeria and South Korea.
At a time when the Earth has marked three consecutive years of record-breaking heat, and ice is melting at an unprecedented rate at the poles, risking massive sea level rise in the decades ahead, some marchers say it is more important than ever for scientists to communicate and work toward solutions to curb fossil fuel emissions.
