Natural Science Forum / Earth Science / Oceanography / December 2005?Changes in N. Pacific currents mirroring recent N. Atlantic?
The UK's National Oceanography Centre reports that currents normally splitting off from the Gulf Stream are weakening. This is now thought to be a 'smoking gun' piece of evidence that the northern 'conveyor' belt system of currents, keeping Europe warm and moderate, is breaking down. This leads to a more general question: Is there any sign that changes in currents in the north Pacific ocean are beginning to happen? One wouldn't expect identical changes, since the connectivity with the Arctic is different compared with the north Atlantic. > The UK's National Oceanography Centre reports that currents normally > splitting off from the Gulf Stream are weakening.

I would have thought that the overly simple model we have relied on for our understanding of this system was unable to break in one place without a knock on effect elsewhere. |
