PMEL scientists Drs. Christopher Sabine and Gregory Johnson participated in the final government approval meeting for the Intergovernmental Panel on Climate Change Working Group I Fifth Assessment Report's Summary for Policymakers (SPM) in Stockholm, Sweden during the week of September 23. Delegates and scientists from 110 countries agreed that warming of the climate system is unequivocal and that it is extremely likely (95% confidence) that human influence has been the dominant cause of the observed warming since the mid-20th century.
The final draft of the full Physical Science Basis report to which PMEL’s Drs. James Overland and Richard Feely also contributed will be out soon.
