Clouds Drive Earth's Growing Heat Imbalance More Than Air Pollution

Clouds Drive Earth's Growing Heat Imbalance More Than Air Pollution

Scientists found that Earth is getting warmer because it's absorbing more energy than it's releasing.

They thought air pollution was the main reason, but a new study shows that changes in clouds are actually the bigger problem.

Clouds usually reflect sunlight back into space, keeping Earth cool.

But lately, clouds have been less reflective, letting more sunlight in.

This is happening because of natural changes and warming at the Earth's surface.

Air pollution does affect clouds, but its impact isn't as big as previously thought.

In the north, cleaner air lets more sunlight through, while in the south, natural events like wildfires make clouds more reflective.

The study helps us understand what's really causing global warming and how to plan for it better.
