Climate diplomats beginning work on the next report from the Intergovernmental Panel on Climate Change — the crucial assessment on global warming that helps shape policy for governments to companies — are meeting in China this week without US officials.

US government scientists participating in the IPCC’s global assessments were issued a stop-work order from the Trump administration, according to media reports late last week. NASA’s chief scientist Kate Calvin, who holds a leadership role in the new report cycle, is not attending the meeting, a spokesperson from the space agency said on Monday.
