Oceans Have Absorbed 60% More Heat Than Scientists Thought

Landmark report from the UN's Intergovernmental Panel on Climate Change published last month

The landmark report from the UN's Intergovernmental Panel on Climate Change published last month warned that humans needed to reduce greenhouse gas emissions 45 percent below 2010 levels by 2030 for us to have a shot at limiting global warming to 1.5 degrees Celsius above pre-industrial levels.

Now, another study published in Nature Wednesday found we might have even less time than that. This is because the oceans have been absorbing much more heat than previously calculated, meaning the earth is more sensitive to carbon dioxide emissions than scientists thought.

"We thought that we got away with not a lot of warming in both the ocean and the atmosphere for the amount of CO2 that we emitted," research leader and Princeton University geoscientist Laure Resplandy told The Washington Post. "But we were wrong. The planet warmed more than we thought. It was hidden from us just because we didn't sample it right. But it was there. It was in the ocean already."

How Much More Warming Is This?

In the past 25 years, the oceans have warmed 60 percent more than previously thought.

What Does This Mean?
