A new study from scientists at the University of Miami (UM) Rosenstiel School of Marine, Atmospheric, and Earth Science suggests that the pattern of temperature change of the world’s oceans may not be an indication of an impending abrupt climate change event as depicted in the movie “The Day After Tomorrow.”
The UM Rosenstiel School researchers used a state-of-the-art climate model to investigate a pattern of temperature change in a swath of water in the subpolar North Atlantic region, called a warming hole, that has been cooling over the past century. Scientists have considered this cooling a result of a slowdown of a planetary-scale ocean circulation, called the Atlantic meridional overturning circulation (AMOC), that transports energy to the North Atlantic.
“However, our study shows the warming hole during the past century is unlikely due to a slowdown of the AMOC. Instead, the warming hole is actually a consequence of human driven changes in the atmosphere” said Chengfei He, a postdoctoral researcher in the Department of Atmospheric Sciences at the Rosenstiel School. “Our finding suggest that this warming hole will not result in an abrupt climate change event lethal to humans as depicted in Hollywood movies.”
Geological records, such as the ice core in Greenland, have revealed that most abrupt climate changes in Earth’s past were the result of a slowdown in the AMOC. “The warming hole is believed as a fingerprint of the AMOC in present day. Its appearance suggests the AMOC may not be stable. Our results do not support this idea,” said Amy Clement, a professor in the Department of Atmospheric Sciences at the Rosenstiel School, and a co-author of the study.
