Définitivement placé sous le signe de la religion, le second mandat du président américain est marqué par le rôle croissant de l’agence, mise en place pour renforcer la place dominante du christianisme dans le pays et au-delà.

Théologie de la prospérité, pensée hostile aux Lumières, antiwokisme, libertarisme techno-chrétien... Tour d’horizon des idéologies dont ceux qui comptent dans l’ère Trump II se réclament.

The White House has instructed NASA employees to terminate two major, climate change-focused satellite missions. As NPR reports, Trump officials reached out to the space agency to draw up plans for terminating the two missions, called the Orbiting Carbon Observatories. They've been collecting widely-used data, providing both oil and gas companies and farmers with detailed information about the distribution of carbon dioxide and how it can affect crop health.

The EU have introduced a new regulation on the import of products linked to deforestation – but will this reduce deforestation globally?

Years before the climate crisis was part of national discourse, this memo to the president predicted catastrophe

Vegetated areas above the treeline in the Alps have increased by 77% since 1984, the study says. While retreating glaciers have symbolised the speed of global heating in the Alpine region, researchers described the increases in plant biomass as an “absolutely massive” change.

A succession of record-breaking natural disasters have swept the globe in recent weeks. There have been serious floods in China and western Europe, heatwaves and drought in North America and wildfires in the sub-Arctic.

Throughout Earth's history, CO2 is thought to have exerted a fundamental control on environmental change. Here we review and revise CO2 reconstructions from boron isotopes in carbonates and carbon isotopes in organic matter over the Cenozoic—the past 66 million years. We find close coupling between CO2 and climate throughout the Cenozoic, with peak CO2 levels of ∼1,500 ppm in the Eocene greenhouse, decreasing to ∼500 ppm in the Miocene, and falling further into the ice age world of the Plio–Pleistocene. Around two-thirds of Cenozoic CO2 drawdown is explained by an increase in the ratio of ocean alkalinity to dissolved inorganic carbon, likely linked to a change in the balance of weathering to outgassing, with the remaining one-third due to changing ocean temperature and major ion composition. Earth system climate sensitivity is explored and may vary between different time intervals. The Cenozoic CO2 record highlights the truly geological scale of anthropogenic CO2 change: Current CO2 levels were last seen ar
