"Amid rising repression of climate science domestically, researchers from universities around the country are lending their expertise to an international effort." 

"Even as the U.S. federal government rapidly retreats from science-based decision-making, adopts climate-damaging energy policies and disengages from international climate efforts, 46 American researchers have been chosen as authors for the upcoming three main global climate reports from the Intergovernmental Panel on Climate Change. 

The number of U.S. scientists working on the IPCC reports has decreased markedly over the past decade, from 210 during the panel’s 5th assessment cycle to 46 in the current cycle, according to the panel’s records. But there are still more Americans or scientists with dual citizenship and U.S. university affiliations contributing to the reports than from any other country.

Former NASA chief scientist and senior climate adviser Katherine Calvin, whose role with the international panel was unclear after the Trump administration fired her from the federal agency, is among them. She will co-chair one of the three main assessment groups, IPCC Chair Jim Skea said last week."
