A new study shows that natural dust particles swirling in from faraway deserts can trigger freezing of clouds in Earth's Northern Hemisphere. This subtle mechanism influences how much sunlight clouds ...

Low clouds also feed into this effect as they reflect away sunlight. The scientists scoured NASA satellite data, weather data and climate models and found the decline in low clouds reduced the ...

Instead, it seems to be due to decreased reflection of incoming sunlight by the Earth. While there was a general trend in that direction, the planet set a new record low for albedo in 2023.

Blocking sunlight the old-fashioned way. Sort of. Cloud Nine In a bid to halt the foreboding march of global warming, scientists are exploring the injection of aerosols, or tiny particles, into ...
