More than 2,000 scientists on Thursday pledged to take part in the Global Climate Strike and week of action beginning Friday, joining the labor movement, Amazon workers, and teachers in refusing to allow children to carry the burden of securing the planet’s future by demanding climate action.

“Scientifically, we succeeded in explaining the causes and cures of the climate crisis. But at a more fundamental level, we failed to transform our societies and lower our emissions. The climate striking youth are calling us all out of our comfort zones, and it is now the duty of scientists and all adults to support them.”
—Dr. Julia Steinberger, University of Leeds

The scientists, who conduct their research in more than 40 countries, wrote in an open letter that “solid, incontrovertible evidence” supports climate campaigners’ grave concerns about the effect of uncontrolled carbon emissions on the planet.

Adults, especially those from the field whose research is the basis for the climate action movement that’s gained momentum in the past year, must join young people in calling for an end to fossil fuel extraction and a rapid shift to renewable energy sources, the scientists said.

“Those of us who teach may cancel our classes—or move them outside and turn them into teach-ins for the whole community,” the scientists added. “Those of us engaged in research will leave the lab bench or the computer screen for an afternoon and join other citizens in calling attention to the crisis.”

The scientists announced their participation a day after Greta Thunberg, the 16-year-old Swedish activist who inspired the Global Climate Strike, testified before Congress by directing lawmakers’ attention to the science of the climate crisis.

Instead of offering an opening statement, Thunberg implored legislators to read the Intergovernmental Panel on Climate Change’s (IPCC) report detailing how the effects of the climate crisis will be irreversible by 2030 unless world governments drastically reduce carbon emissions—a report officials have had access to for nearly a year.

“Students have led and we must follow—in defense of the scientific truths our colleagues have discovered over the decades, and of the planet we love,” the scientists wrote Thursday.

Dr. Julia K. Steinberger, a social ecology professor at the University of Leeds, said scientists have a responsibility not only to share their findings with the public but to stand alongside their fellow citizens in the fight against the “war on science.”
