After a Falcon 9 rocket stage burned up in the atmosphere, vaporised lithium and other metals drifted over Europe. This ...

Spacecraft burning up in the atmosphere are leaving behind metal particles. Scientists are racing to understand if that affects the climate. One risk is that these particles may spark rainbow-colored ...

NASA research has shown that increasing water-vapor in the stratosphere, which results partially from greenhouse gases, may delay ozone recovery and increase the rate of climate change. Drew Shindell, ...

The study found that those aerosols could warm parts of the upper atmosphere by about 1.5 degrees Celsius within one or two ...

A 3D rendering of the ozone hole evolution in 2025. Forty years after global policymakers began grappling with the crisis posed by a gaping hole in Earth’s protective ozone layer over Antarctica, the ...

A new study suggests that explosive events in space have the potential to temporarily switch off the natural shield that protects us from harmful solar radiation. By Katrina Miller On Oct. 9, 2022, ...

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

An ozone sonde is released from the Balloon Inflation Facility at the South Pole Station earlier this year. Ozone depletion above Antarctica was much less this austral spring due to warmer ...
