Moving beyond marine protected areas, researchers propose active "marine rewilding" to restore degraded ocean ecosystems.

Key principles include restoring food webs, reconnecting fragmented habitats, and integrating coastal communities to build resilience against climate impacts.
How to enhance ocean health and resilience with marine rewilding
Ocean ecosystems are under extreme stress on several fronts including overfishing, ocean acidification, climate change and marine warming. While ocean conservation efforts often tend to focus on…

#DidYouKnow that wetlands are among the most severely degraded ecosystems on Earth?

The @ipbes.net  #LandDegradation assessment reports that 87% of wetlands have been lost globally over the last 300 years, including 54% since 1900, primarily due to agricultural conversion and urbanisation.

NEW BRIGHT SPOTS: A district heating system in France has run since 1332, still warming 100+ homes from hot springs.

The tech is 700 years old. What's changed is what we can plug in: heat from rivers, flooded coal mines, breweries, data centres.

NEW from me: China's CO2 emissions fell by 1% in the second quarter of 2026, as oil consumption plummeted amid the Strait of Hormuz crisis, with EVs and public transport among the key factors. Oil consumption fell by 9% overall and by 16% for transport. 🧵

LUCA aurait pu être une sorte de système chimique précurseur de la vie, dans des cheminées hydrothermales, mais pas encore véritablement un organisme autonome

À titre de comparaison, en 2022, pourtant marqué par les gigantesques feux de Landiras et de La Teste-de-Buch, les assureurs avaient déboursé « seulement » 80 millions d’euros.

L’été 2026 est, de loin, le + chaud jamais observé en France, devançant 2003 de 0,8°C. Seulement 5 jours sous les normales, contre 86 au-dessus. Il laisse derrière lui une agriculture en lambeaux et des écosystèmes à l’agonie.

Underappreciated: US farmland *already substantially produces energy, not food*, and does so very inefficiently. Corn ethanol (~40% of all US corn) requires about 100 times more land per vehicle-mile driven than solar photovoltaics -> electric vehicles. Shifting corn to solar *would free up land*.
anytime people raise concerns about land use for solar projects or anything like that i just want to point out that half the corn we grow in this country gets used to make gasoline slightly worse
