I heard him years ago at a financial conference in New Orleans, where he was the hit of the conference. Spoke the next year too as I recall. Despite his great work in these fields he was not widely recognized by the "establishment" since it didn't fit their stale old notes. So he just made a fortune instead as a PRIVATE weathercaster for large international conglomerates whose fortunes varied with global weather. They just LOVED him.
Unfortunately, as too often happens with great men, he made a bad call (the New Madrid non-earthquake) not long before his death and that is how too many, especially his enemies, choose to remember him.) I think you would enjoy his book Climate and the affairs of men.
