From Terry McDonell's letter from the editor in the current issue:
The magazine received nearly 800 letters about the cover story on global warming (Going, Going Green, March 12)--most of them taking issue with the subject matter and suggesting that SI stick to sports and pay more attention to business as usual...These stories were always controversial. This time some readers suggested they didn't want Al Gore running the magazine. Chicken Little was also mentioned. Other letters pointed out that Mars is warming, and one contained a lefthanded reference to the earth's being flat: "Why are you buying into that stuff? There's no more 'scientific consensus' on global warming than there is that the earth is flat." The temptation, of course, was to run a correction that read, "The earth is flat. SI regrets the error."
