Fig 1. Integration of solar data departing from long term average as a proxy for OHC
OK, this the last post before I go. This is a comment I made this morning over at Pierre Gosselin’s place.
To understand the effect of solar variation on a large heat capacity mass like Earth’s oceans, you have to integrate the solar data to get a reasonable proxy for ocean heat content. If you look at empirical comparisons of average sunspot number during periods when the ocean temperature is steady, you can derive a value of approximately 40 sunspots per month. This also happens to be the average sunspot number over the period of record from 1749 to today. Integrating the sunspot numbers as a running total departing from this average produces a reasonable proxy for OHC.
Calibrating the Steinhilber et al TSI reconstruction based on 10Be to the same baseline, we…
