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 ...

Communications companies such as Starlink plan to launch tens of thousands of satellites into orbit around Earth over the next decade or so. The growing swarm is already causing problems for ...

According to data from the United Nations Office for Outer Space Affairs, 2023 was a record year for launching satellites, probes, landers and more into space. But scientists worry those plumes of ...

It may sound like the plot of an old James Bond movie, but an idea to "dehydrate the stratosphere" to slow climate change is real. In a study released Wednesday in Science Advances, researchers ...

Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone-depleting substances high into the atmosphere over East Asia, according to new research.

Daily life increasingly depends on systems of satellites orbiting Earth. As fleets proliferate, ever greater numbers of expired units will hurtle back toward the surface. Decommissioned satellites ...

A new climate intervention strategy aims to decrease the amount of water vapor in the stratosphere by injecting it with ice-forming nuclei. The idea is that, by reducing the water content, more heat ...

It’s been an unsettled winter in the atmosphere above Antarctica. About 30 kilometers above the continent’s icy surface, in the layer known as the stratosphere, a series of warming events took place ...

Ozone from the stratosphere - 10 miles above ground, plunged to the surface producing air quality alerts across southern Colorado on Monday. This is rare. And, it came on top of the intense and ...

The world is warming. This fact is most often discussed for Earth's surface, where we live. But the climate is also changing from the top of the atmosphere to the bottom of the ocean. And there is a ...
