Solar with Various Cumulative Lags
Since the actual temperature data for the longer time frames is not very accurate relative to the "impact" trying to be determined, the blur provides a sanity check for the more devoted Cyclomaniacs.
The trailing cumulative lag averaging is just a cheat for comparing data sets. Most of the data is already averaged and seasonally adjusted to death so a proper integration of smoothed and seasonally adjusted data is most like mathturbation of the finest kind. A. M. Selvam among others have mentioned that cumulative impacts should be considered, my simply Cumulative Lags do just that. If they need to be fine tuned once more reliable data is available, then so be it.
Update: This chart uses the 31.5 year cumulative average plus I added the BEST volcanic forcing with BEST global and ERSSTv3b tropics and extratropics all spliced to the Oppo 2009 Indo-Pacific Warm Pool reconstruction.
