The AMOC (Atlantic Meridional Overturning Circulation) is now creaking under the weight of all that Pacific heat in the ocean. If that goes - which is looking increasingly likely within the next 25-50 years - then sayonara Gulf Stream and Europe can look forward to what's likely to be extremely sub-zero winter temperatures and soaring summer temperatures.
