Here is the sea surface temperature anomolies for the North Atlantic, overlays with the Gulf Stream. The average surface temperature is Approx 1.7°C below average for this time of year.
It's this significant? We do not know the temperature of the subsurface. But the Gulf Stream Does seem top peter out when it hits this cold patch. Ì would have thought it would reach as far as Iceland.
3 Trillian joules of heat is a lot of warmth that Europe will see. A cold winter in England won't be Russia's fault. Still, given the sudden demand for heating has one might anticipate a price rise.
In any event is this a topic of conversation at coffee break among Climatologists? And what has caused it.?
