Watts Up With That?

Guest post by David Archibald

My papers and those of Jan-Erik Solheim et al predict a significant cooling over Solar Cycle 24 relative to Solar Cycle 23. Solheim’s model predicts that Solar Cycle 24, for the northern hemisphere, will be 0.9º C cooler than Solar Cycle 23. It hasn’t cooled yet and we are three and a half years into the current cycle. The longer the temperature stays where it is, the more cooling has to come over the rest of the cycle for the predicted average reduction to occur.

So when will it cool? As Nir Shaviv and others have noted, the biggest calorimeter on the plant is the oceans. My work on sea level response to solar activity (http://wattsupwiththat.com/2012/02/03/quantifying-sea-level-fall/) found that the breakover between sea level rise and sea level fall is a sunspot amplitude of 40:
