And what of Dr. Miskolczi, who gave up his NASA job to publish? Also “not cogent”?
I have observed that certain people have a deep emotional need to believe in this global-warming nonsense. Perhaps for some it fills the void left by absence of belief in older more traditional religions. Of course Dr. Michael Crichton stated the case better than I ever could:

Sure, and there are some that work backwards based on their political choices. I am conservative and I don't want any government involvement in climate whatsoever. But I am also basing my decisions on sound science and the greenhouse effect is sound. Man's growth of CO2 is sound. That increase in CO2 causing warming, debatable. Catastrophic? No chance, at least a lot less than other catastrophes. Not worth worrying about at all.
My suggestion is getting some good material from the skeptical side. Crichton is a good start. Find climate scientists. Avoid physicists like the guy you posted above. They tend to oversimplify or just not comprehend.
