Here are four questions related to global warming, especially for those in denial:
(1) Does the atmosphere contain carbon dioxide? (2) Does atmospheric carbon dioxide influence global temperature?
(3) Will that influence be enhanced by the addition of more carbon dioxide? (4) Have human activities led to a net emission of carbon dioxide?
It would be interesting to find out which of these questions people like Patrick Michaels, the "state climatologist" of Virginia, answer "no," because this would be the point at which these people choose to part company with basic physics ["No, Virginia, the sky is not falling," Dec. 3].
It's past time to cut the horse feathers about the debate on the existence of global warming.
Debate seems to exist only in the media (with the help of certain people in high places), and it's time the media stopped behaving like the public relations arm of the fossil-fuel lobby.
