Global drought extremes in 2025

In 2025, global annual drought affected ~30% of the global land surface.

Drought is no longer just about rainfall.

It’s about temperature and evaporative demand.

Drought Drove the Amazon’s 2023 Switch to a Carbon Source - Eos The change was caused by thirsty vegetation taking up less carbon than normal, not by the year’s extended fire season, new research shows.

It was thirsty plants taking up less carbon—rather than fires—that caused the Amazon’s 2023 switch to a carbon source, new research finds.

With the Ocean Included, the Social Cost of Carbon Doubles - Eos A new calculation includes ocean ecosystems when assessing the monetary impact of climate change.

When researchers considered climate change’s impacts on the ocean, calculations of the cost of climate change nearly doubled.

California vents: Together with @mbarinews.bsky.social and other partners, we set sail on Monday to investigate barium-rich water seeps on the ocean floor. The dives of the ROV MARUM QUEST-5000 can be followed live.
