How Antarctic clouds could help reveal the effects of climate change
July 22, 2026
Antarctica’s massive ice sheet acts as a global heat sink. As a result, changes in the make-up of Antarctic clouds, such as the amount of ground they cover or how much radiation they absorb, can have ripple effects as far away as the tropics. Climate change researchers need to understand the physics of these clouds if they are to correctly work out how weather around the globe will change as the polar regions warm.
