Abstract

Over the 12-month span ending in June 2024, global surface temperatures remained at or above 1.5°C above pre-industrial levels—a milestone often associated with the upper limit set by the Paris Agreement. But does this signify that the world has already breached the long-term climate goal? A new study by climate scientist Alex J. Cannon, published in Nature Climate Change, addresses this pressing question with fresh insight from climate model projections.
