Just a quick post on the silliness about the Sun not having ANY (less than a tenth of a degree) impact on climate. That is just an indication of how ridiculous people ca be once obsessed with pet theories.
Well, the "SST" data isn't SST data. It is a mixture of measurements of the ocean bulk mixing layer from just under the surface to as much a 10 meters below the surface. "SST" would not imediately indicate changes in temperature due to seasonal and longer solar variations since the SST north and south of the equator is isolated by Coriolis effects. It looks to take about 27 to 30 months for the equator temperatures to equalize which just happens to be about the same frequency as the Quasi-Biennial Oscillation (QBO).
So what about that weird down in 1940 and up around 1980? Do ya think that it might take longer for other areas to equalize thermal imbalances?
If you want to blame any other changes on CO2, land use or unicorn farts, you need to figure out the basic stuff first. Have fun.
