greenland ice sheet
The Greenland Ice Sheet could cause Atlantic Ocean currents to shut down.
  • The ocean currents in the Atlantic are headed toward a total shut down, a new study shows.
  • If that happens, less heat is exchanged across the globe and Europe could go into a deep freeze.
  • Northwestern European temperatures could plunge by 9 to 27 degrees Fahrenheit over the decades.

An abrupt shutdown of Atlantic Ocean currents that could put large parts of Europe in a deep freeze is looking a bit more likely and closer than before as a new complex computer simulation finds a “cliff-like” tipping point looming in the future.
