Ancient Plankton Reveal a Surprise About Future Ocean Oxygen
A new study suggests that some of the world’s oxygen-deprived oceans could eventually regain higher oxygen levels in the centuries ahead, even as the planet continues to warm. About 16 million years ago, the Arabian Sea contained more oxygen…

Why Scientists Are Rethinking 60 Years of Arctic Snow Data
Decades of advances in satellite observation made it seem as though Arctic snow cover was growing, when in reality satellites were simply becoming better at detecting smaller and shrinking amounts of snow. For many years, reports from the United…

A Hidden Atmospheric Shift Let Methane Surge Worldwide
Atmospheric methane rose faster than ever in the early 2020s, driven less by fossil fuels and more by changes in nature itself. Methane levels in Earth’s atmosphere climbed at an unprecedented pace in the early 2020s due to a mix of weaker…
