Quantifying when 1.5°C of global warming has been exceeded 

A new preprint co-authored by CCAC Scientific Advisory Panel member Sophie Szopa explores how to determine when long-term global warming has exceeded the Paris Agreement’s 1.5°C threshold. The study examines the methodological challenges involved and proposes a robust framework for estimating long-term warming in real time.
