Sunspot Cycle and the Global Temperature Change Anomaly

I have made an 82% correlation between the sunspot cycle and the Global Temperature Anomaly. The correlation is obtained through a non linear time series summation of NASA monthly sunspot data to the NOAA monthly Global Temperature Anomaly.

This is interesting.... I think the sunspot cycles do in fact have some forcing on the temperature of earth. The question being is how much?

Correlation of global temperature with solar activity

Even the WUWT crowd pointed out it was a pointless exercise in curve fitting, with no attempt to explain where the various mathematical factors came from. Given enough terms, you can fit a curve to anything. Trouble is, it always fails badly outside of the interval you fit the curve to.

There is, of course, some correlation with sunspot numbers, as low sunspot numbers are correlated with lower solar output. That's why the 11-year sunspot cycle is weakly echoed in the temperature record. However, the growing baseline of GHG warming is overwhelming the weak 11-year cycle.

Mamooth you're very much right...The 11 year cycle has short term forcing on the climate but it isn't what is driving the warming.
