One wrong guy does not negate a whole field of science.
Any time I see Geowatch.org as a reference I am suspicious. I cannot tell you as a university researcher of 30 years in radar, RF, electronics, electricity, etc. just how disingenuous I found that ‘thing’ to be. IMO, a complete scam artist.
As for your other references re: a cycle of warming, dryness, cooling or the like, yes I can agree that that sort of cycle is probably (may be) true. I am just tired of hearing that humans are responsible for it all in just the last 100 years or so.
