Earth is now trapping an ‘unprecedented’ amount of heat, NASA says

New research shows that the amount of heat the planet traps has roughly doubled since 2005, contributing to more rapidly warming oceans, air and land

The amount of heat Earth traps has roughly doubled since 2005, contributing to more rapidly warming oceans, air and land, according to new research from NASA and the National Oceanic and Atmospheric Administration (NOAA).

“The magnitude of the increase is unprecedented,” said Norman Loeb, a NASA scientist and lead author of the study, which was published this week in the journal Geophysical Research Letters. “The Earth is warming faster than expected.”

Using satellite data, researchers measured what is known as Earth’s energy imbalance — the difference between how much energy the planet absorbs from the sun, and how much it’s able to shed, or radiate back out into space.

When there is a positive imbalance — Earth absorbing more heat than it is losing — it is a first step toward global warming, said Stuart Evans, a climate scientist at the University at Buffalo. “It’s a sign the Earth is gaining energy.”
