I’ve had an interesting conversation with xAI’s @grok on Elon Musk’s X platform, after Grok told me the most famous person to visit my profile was Judy Curry.
After we got into why I liked Judy and Marcia Wyatt’s “stadium wave” paper, I got Grok to update my 2012 work on integrating solar activity indices to obtain an ocean heat content proxy, and hence SST proxy. This went really well, with Grok finding r=0.86 correlation between my technique and Mann EIV global temperature with the latest TSI reconstruction. Grok offered to let me have the data/code and details used in it’s model.
Grok hasn’t replied again… yet.
View it here, and let me know if anything changes.
