How do ice sheets melt?
Scientists observed a glacier collapse in Greenland and proposed a new model of how ice sheets melt. Their model describes water as both…
The history of tsunami-causing earthquakes in Japan
Researchers pieced together clues from seismic data and sediment samples to unravel the history of tsunami-causing earthquakes in the Japan…
Plants changed the chemistry of magmas
Researchers used isotopes in magmatic minerals to demonstrate that continental magmas altered globally around 450 million years ago…
Does the Arctic Ocean regulate or amplify global warming?
Researchers found that interactions between methane gas and seawater affected greenhouse gas emissions from the Arctic Ocean during a past…
Why the 2023 El Niño broke records
Researchers found that the 2023 El Niño event was fueled primarily by heat stored in the ocean rather than in Pacific winds.
Why do deep-sea microbes have such small appetites?
The deep sea is one of Earth’s largest reservoirs of carbon, yet microbes don’t consume very much of it. Researchers showed that this is…
Ice shelf collapse reveals early warning signs of melt
Scientists found that growing fractures caused an East Antarctic ice shelf to collapse.
Carbon feedbacks 56 million years ago similar to today
Geologists simulated the chemistry of Earth's past oceans and atmosphere using mineral data from the ancient seafloor. They found a…
Volcanism warmed past Earth
Geologists dated a global warming event about 180 million years ago. They found it lasted between 169,000 and 417,000 years and was linked…
