Youth For Climate 3

An international group of researchers has produced a third update to key indicators of the state of the climate system set out in the IPCC AR6 assessment, building on previous editions in 2023 and 2024. Forster et al. (2025) assess emissions, concentrations, temperatures, energy transfers, radiation balances, and the role of human activity and conclude that, while natural climate variability also played a role, the record observed temperatures in 2024 were dominated by human activity and the remaining carbon budget for 1.5° C is smaller than ever.

Le seuil de 1,5 °C de réchauffement planétaire sera dépassé sur plusieurs années, alerte un consortium international de scientifiques. Problème : le budget carbone pour le limiter sera bientôt épuisé.

Een internationaal team van wetenschappers werkt aan een systeem dat de achtjaarlijkse rapporten van het VN-klimaatpanel aanvult met een actuele stand van zaken per jaar. Klimaatexpert Piers Forster van de Universiteit van Leeds legt uit waarom dat zo belangrijk is, en wat de laatste bevindingen zijn.

After the second world war, many of Japan’s smartest scientists found jobs in North American laboratories. Syukuro (Suki) Manabe, a 27-year-old physicist, was part of this brain drain. He was working on weather forecasting but left Japan in 1958 to join a new research project by the US Weather Service to develop a numerical model that could be used to study the climate...
