Global Ocean Circulation Appears To Be Collapsing Due To A Warming Planet
I'm a little hesitant about the title. The slowdown of the Atlantic Meridional Overturning Circulation is not the same thing as the "collapse of global ocean circulation". It might be more accurate to say that the AMOC is at risk of collapsing in a warming world.
Also, it's worth noting that although we understand that there is a connection between AMOC and the amount of carbon dioxide in the atmosphere, the mechanisms involved in this connection are still under investigation.
This link appears to go to an irrelevant article. Here are two relevant articles on the "warming hole":
Evidence is growing that the comparatively cold zone within the Northern Atlantic could be due to a slowdown of this global ocean water circulation.
For example, this study (Rahmstorf et al, 2015):
