Not the day after tomorrow: Why we can't predict the timing of climate tipping points

A study published in Science Advances reveals that uncertainties are currently too large to accurately predict exact tipping times for critical Earth system components like the Atlantic Meridional Overturning Circulation ...

Scientists pin down the origins of the moon's tenuous atmosphere

While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically ...

Investigating the link between N₂O ionization and ozone depletion

Man-made emissions of nitrous oxide (N₂O) are rapidly increasing globally and are predicted to pose a growing threat to Earth's ozone layer. In the 1970s, it was discovered that N₂O in the upper atmosphere can trigger ...
