The amount of heat trapped by Earth’s land, ocean, and atmosphere doubled over the course of just 14 years, a new study shows.

To figure out how much heat the earth was trapping, researchers looked at NASA satellite measurements that tracked how much of the Sun’s energy was entering Earth’s atmosphere and how much was being bounced back into space. They compared this with data from NOAA buoys that tracked ocean temperatures — which gives them an idea of how much heat is getting absorbed into the ocean.

The difference between the amount of heat absorbed by Earth, and the amount reflected back into space is called an energy imbalance. In this case, they found that from 2005 to 2019, the amount of heat absorbed by Earth was going up. Their…
