Re: “M.D. Harmon: No sound basis for concluding 2014 was ‘warmest year on record’ “ (Jan. 30):

Mr. Harmon’s latest attempt to dismiss global climate change reminded me of a conversation I had last summer with someone who insisted the Earth is 4,000 years old. He was pleasant enough, but really, what’s the point?

Mr. Harmon will be that guy wading along Commercial Street some years in the future when Casco Bay has jumped its banks, crying, “See, I told you it was a sham! The water is no higher than my knees!”
