Warming a hot topic

I don’t know whether Michael Graham has any children, but if he does, just think about what they may be saying to him sooner rather than later (“Separating facts from climate-change fearmongering”). Dad, did you really think that the California wildfires were just ordinary events? What about flooding up and down the Mississippi? How about record temperatures in the Arctic? And ice melting in Greenland and Antarctica? Did you even know about the thawing of the permafrost in Canada and Siberia? And why did you quote the long-discredited climate change denier Bjorn Lomborg? Don’t you care about leaving us a habitable world to live in? — Larry Rosenberg, Cambridge
