Air quality in America’s largest cities has steadily improved thanks to tighter regulations on key sources of particulate pollution.
Antarctic Sea Ice Emerges as Key Predictor of Accelerated Ocean Warming
A groundbreaking study published today in the European Geosciences Union (EGU) journal Earth System Dynamics provides a critical and previously underestimated connection between Antarctic sea ice, cloud cover, and global warming.
Rare Glimpse at Understudied Ecosystem Prompts Caution on Deep-Sea Mining
An enormous but poorly understood region of the global ocean–referred to as the abyssal benthic boundary layer–lies a few meters above the seafloor and has only been sampled a handful of times.

1,000 Swiss glaciers already gone, and the melting is speeding up
Swiss glaciers lost nearly 3% of their volume in 2025, following a snow-poor winter and scorching summer heatwaves. The melt has been so extreme that some glaciers lost more than two meters of ice thickness in a single season. Scientists caution that the decline is destabilizing mountains, raising risks of...
Before they sucked blood, leeches were ocean hunters

Saturn’s icy moon Enceladus just revealed stunning new clues to life
Fresh analysis of Cassini data has revealed new complex organic molecules inside ice grains spewing from Enceladus. These discoveries strengthen the case that the moon’s underground ocean hosts chemistry similar to life’s building blocks on Earth. Scientists now believe Enceladus could be habitable, and plans are underway for a European...
