Apparently there's a "March for Science" planned.
Its facebook page has about 300k likes in a couple of days, so looks like it could be big.
March for Science is an effort comprised of dozens of independent, nonpartisan coordinators. Recent rhetoric has inspired us to march on Washington D.C. and in Satellite Marches across the country. Our mission statement is as follows:
THE MARCH FOR SCIENCE CHAMPIONS PUBLICLY FUNDED AND PUBLICLY COMMUNICATED SCIENCE AS A PILLAR OF HUMAN FREEDOM AND PROSPERITY. WE UNITE AS A DIVERSE, NONPARTISAN GROUP TO CALL FOR SCIENCE THAT UPHOLDS THE COMMON GOOD, AND FOR POLITICAL LEADERS AND POLICYMAKERS TO ENACT EVIDENCE-BASED POLICIES IN THE PUBLIC INTEREST.
