Global heat stress is intensifying on every continent. 👉 More extreme “feels-like” temperatures 👉 Hotter nights warming faster than hotter days 👉~50 extra heat-stress days per year in some regions 👉 Rising exposure driven by both climate change and population growth www.nature.com/articles/s41...

Global heat stress intensification and its expanding footprint on the human population - Nature Climate Change

The authors assess global changes in heat stress since 1950, considering daytime extremes, nocturnal heat and compound day–night events. They show multidimensional intensification, with an increased f...

There may be a former parasite in every living cell. The ribosome, an organelle that builds proteins, may have started out as a parasite taking advantage of cells before the host-parasite interaction evolved into a permanent mutualism. In PNAS Nexus: https://ow.ly/gnJj50Yo8ic

A ribosome synthesizes protein based on mRNA information. The mRNA strand carries genetic code. The ribosome decodes mRNA to form a protein chain. Stock image.

« Face au défi climatique, la seule réponse, c’est s’adapter ». FAUX. La SEULE réponse est la neutralité des émissions. Le PNACC est indispensable pour s’adapter à un climat DÉJÀ réchauffé et préparer la suite. Mais à +3ºC monde (4ºC France), on ne s’adapte plus. On choisit qui on sauve.

[1/10] La ministre Agnès Pannier-Runacher a présenté le 3e Plan national d’adaptation au changement climatique #Pnacc-3. Objectif : préparer la #France à un réchauffement de +4°C d’ici 2100. Il prévoit 52 mesures mais manque encore de moyens et d’un cadre juridique contraignant. #geography #risks
