Michael Ivey displays for the world his own sad lack of scientific understanding when he claims that carbon dioxide “is not now and never has caused Earth’s atmosphere to warm” [“Climate-change Believers Betray Their Naiveté,” July 8, Xpress]. How and why CO2 acts as a greenhouse gas is well understood and documented in the scientific literature, whether Ivey believes it or not.
Credible information is available on the web for those who want to examine it. Too bad that many of our politicians also subscribe to the abundant “conspiracy” notions afloat in today’s thinking. We seem to be living in a society that wears scientific ignorance as a badge of honor.
