Not just the #GulfOfMaine waters that are cooling all of a sudden...
Waters off Scotian Shelf are cooling, but scientists can't say for how long
Lower temperatures have scientists wondering if decade-long warming trend is over

"Since 2012, ocean temperatures off Nova Scotia at depth have been consistently warmer — by about two degrees above normal.
"For example, near-bottom warming anomalies were detected in the Cabot Strait between Cape Breton and Newfoundland, Misaine Bank off Cape Breton, Emerald Basin on the Eastern Shore and Lurcher Shoal, Georges Basin and Georges Bank off southern Nova Scotia.
"The large and abrupt warming was enough to constitute a regime shift, said Dave Hebert, an ocean climate scientist who has run the Maritimes survey twice annually for many years.
"Regime shift indicates a persistent change in the structure and function of the ocean ecosystem."
"Europe is the fastest-warming continent and its temperatures are rising at roughly twice the global average, two top climate monitoring organizations reported Monday, warning of the consequences for human health, glacier melt and economic activity."
Kipppunkt Ozeanströmung: Zu viele Untergangsszenarien?
Die nordatlantische Umwälzzirkulation könnte kippen, hieß es zuletzt häufig. Aber was genau bedeutet das? Was ist eigentlich ein Kipppunkt? Und ist es angemessen, dass so viel darüber gesprochen wird? Von Yasmin Appelhans.
A new study suggests that the Atlantic overturning circulation AMOC “is on tipping course”
"It’s observational data from the South Atlantic which suggest the AMOC is on tipping course. Not the model simulation, which is just there to get a better understanding of which early warning signals work, and why."
This is not really good news. The point that AMOC collapse is demonstrated in complex models (CESM1) means that it looks to be real. AND the early warning indicators point towards us reaching it sometime in the future (although no-one knows exactly when), is worrisome. #AMOC#NorthAtlantic
Good coverage by the Financial Times on the new study on the risk of Atlantic Ocean circulation instability, citing a number of experts. #AMOC
