Climate change is speeding up the destruction of nitrous oxide in the stratosphere, introducing uncertainty into future greenhouse gases level.

Roughly 42,000 years ago, Earth’s magnetic field weakened dramatically during the Laschamps geomagnetic excursion, allowing more cosmic radiation to reach the atmosphere. In a peer‑reviewed study of ...

Climate change is rapidly freshening one of Earth’s saltiest ocean regions in the Southern Indian Ocean, potentially disrupting circulation.

Climate change makes nitrous oxide disappear faster, creating new uncertainty for future climate and ozone predictions.

When the underwater Hunga Tonga volcano erupted in the South Pacific, it blasted an "unprecedented" amount of aerosols and water vapor into Earth's atmosphere. Now, scientists are saying the plume was ...
