A mysterious "cold blob" in the Atlantic Ocean is a sign that key ocean currents are weakening, a new study has found, with potentially devastating long-term impacts on our climate and weather.
The cold blob, or North Atlantic Warming Hole, is an area south of Greenland and Iceland where average sea surface temperatures have actually been going down. Researchers have been working to understand the blob for years, given that it bucks the global trend of Earth getting warmer.
