How Survivors Spanned The Globe After Earth’s Biggest Mass Extinction
Scientists don’t call it the “Great Dying” for nothing. About 252 million years ago, upward of 80% of all marine species vanished during the end-Permian mass extinction – the most […]

Hunga Volcano Eruption Cooled, Rather Than Warmed, Earth’s Southern Hemisphere
When Hunga Tonga–Hunga Haʻapai, an underwater volcano near Tonga in the South Pacific Ocean, erupted in 2022, scientists expected that it would spew enough water vapor into the stratosphere to […]

Ocean Planet Update: Unexpected Amount of Sea Level Rise in 2024
Global sea level rose faster than expected in 2024, mostly because of ocean water expanding as it warms, or thermal expansion. According to a NASA-led analysis, last year’s rate of […]
