“Conversation about the weather is the last refuge of the unimaginative.” – Oscar Wilde
I will state my bias up front. I am convinced by the preponderance of data in favor of man made global warming. At the most simplistic level, I can’t see how converting humongous tons of fossil fuel into CO2 and dumping it into the the atmosphere cannot have effects on the climate. To my mind its like determining vaccine efficacy or evolution. Plausible mechanism(s), good basic science, multiple studies using different lines of evidence that all come to the same conclusion. There are lots of fine points and nuances to be worked out, but the basic truth is reasonable and well defined. Infectious diseases lend some validation to the concept that the world is warming, since with global warming comes a variety of infectious diseases.
It is one big IF:THEN statement. IF global warming, THEN infections. Of course if the IF is not true, then the THEN doesn’t follow.
