This weekend’s science marches on Earth Day shook the world.

Scientists, parents, children, educators, and others took to the streets for powerful mobilizations including teach-ins, dancing, and, of course, marching.

Michael Mann, member of the AAUP’s Committee A on Academic Freedom and Tenure and leading climate researcher at Penn State, spoke and led marchers alongside Bill Nye and other science leaders in Washington, DC.

AAUP members and academics were out in force in cities across the country.

Democracy depends on an informed citizenry. It depends on our ability to study, research and speak out without being silenced, facing retaliation or violence. We will keep marching for scientists, professors and students to pursue the truth and to contribute to the common good.
