Today’s highest temperature was 63 F, which is a record for this date.
Yesterday, though, it was only 53 F, and the record of 64 F was set in 1950. And in 1994, 7 inches of snow fell on January 4.
None of that proves anything about global warming. If 2007 turns out to be the hottest year for the entire planet, ever, I think that proves something.
