An international study, published in Science, has found that only 24% of present-day glacier mass will remain if the world were to warm to 2.7°C, the trajectory set by current climate policies. In contrast, limiting warming to 1.5°C — the target of the Paris Agreement — would preserve 54% of glacier mass.

A new study by Regina R. Rodrigues (co Chair of the WCRP My Climate Risk Lighthouse Activity), Afonso H. Gonçalves Neto, Edson A. Vieira, and Guilherme O. Longo, published in Communications Earth & Environment (https://doi.org/10.1038/s43247-025-02195-3), explores the connection between marine heatwaves (MHWs) and coral bleaching in the tropical Atlantic.

A new paper published by Ditlevsen and Ditlevsen in Nature Communications finds early warning signals of a critical transition of the AMOC system and suggests that it could shut down or collapse as early as 2025 and no later than 2095. For more information, click the heading above.
