If he "went over" to the side of the Consensus, then he probably wouldn't have a very long interview with Rush Limbaugh, I hazard. There are currently three basic levels of global warming skepticism:
High: complete denial of significant human influence, importance of atmospheric greenhouse gases, even denial of an actual observed warming and attribution of CO2 increase to human activity. Prefer business-as-usual scenarios but will occasionally admit reasonability of conservation and technology investment.
Medium: admission of observed warming, attribution to natural variability with minimal human influence, questioning of model accuracy and predictions, adherence to low-impact predictions, do not perceive necessity for alteration of activities now until more data is available.
Low: admission of observed warming, human involvement, and potential problems; remain uncertain about model predictions, preference for low-impact scenarios to high-impact or catastrophic scenarios, prefer market force solutions to mandated regulations*
So, I guess, the question is: "Do we really have the ability to correctly gauge what is causing this current warming"? And if the answer is 'no', then how do we know how to react?
Answer to first question: Incontrovertibly. Which is a "yes".
I would venture that would definitely be a hazard on your part. Mr. Limbaugh puts liberals to the front of the line on telephone calls. He's not afraid, nor unwilling, to discuss issues with anyone who is willing to debate. Perhaps you should call him sometime? BTW, Dr. Spencer phoned Limbaugh the day prior to the interview. After stating some of his opinion, Limbaugh set up the phone interview for the following day. It's not as though Limbaugh set this up himself.
Answer to first question: Incontrovertibly.
So you say (and no, this isn't being sarcastic; just that I'm not going to accept your word for it). I'll continue to reserve judgment until I know I've seen definite proof coming from the scientific community that I deem incontrovertible, based on methodology that has been universally accepted.
