When you say this is just one guy with an internet connection, you are onto something. Check out the blog comments about this guy on Junkscience.com and you will see that he appears to be running a scam. Possibly a scam artiste from way back.
He looks like he is selling snakeoil, unfortunately. We probably are headed for global cooling, but this guy is not the scientist who will demonstrate it.
