We are now in
a SST warming phase, which is independent of global warming, and which was predicted.
Re # 45: You gave the point yourself: «We are now in

Fig 2A shows that there are (small) positive
SST anomalies during these ISOs and (clear) water vapour positive anomalies, at least at the peak of the
warming phase of ISOs.
From the plot above according to HadCru you should be able to see that there was a close conformity between
SST and Land - Air T's up until the recent
warming phase say starting at ~ 1980, but then followed a major deviation during that noted
warming, whilst both elements more recently show distinct plateaus.
When that Arctic forcing is
SST related, it would be lagged and could be out of
phase meaning a global cooling or pause would produce stronger Arctic Winter
Warming and stronger more frequent SSW events.
The most recent decade has the highest
SSTs on record in the tropical North Atlantic (Figure 3.33), apparently as part of global
warming and a favourable
phase of the AMO.
Over the instrumental period (since the 1850s), North Atlantic
SSTs show a 65 to 75 year variation (0.4 °C range), with a
warm phase during 1930 to 1960 and cool
phases during 1905 to 1925 and 1970 to 1990 (Schlesinger and Ramankutty, 1994), and this feature has been termed the AMO (Kerr, 2000), as shown in Figure 3.33.
[*) Another contributing factor to a dominantly positive
phase for the NAO index is current and expected
SST anomaly, with relatively cold waters west of the Azores, favouring high pressure build - up there, and relatively
warm waters off the US - Canadian east coast, favouring northerly Atlantic depression formation (especially during offshore winds).]
Also, his
SST data (see our Fig. 2 above) go back to 1930, thus covering the whole previous
warm phase of the AMO.
