Climate change

Dr. Mehta’s article (Salon, May 26) opens with the statement: “Most people, except perhaps a few diehard oil executives, have accepted that climate change is largely due to human activities.” Four hundred years ago, “most people” accepted that the earth was flat and that the sun revolved around it. I am no authority on climate change but I do believe that the question is by no means as settled as the author assumes. I would strongly urge anyone who has doubts to read Lawrence Solomon’s book The Deniers. Solomon presents opposing views of various important scientists.
