During our last big snowstorm, in December, I unearthed an old column by Robert F. Kennedy, Jr., in which he claimed that the winters in D.C. have become anemic, that global warming is to blame, and that his anecdotal memories prove the perfidy of oil companies that try to explain global warming away.
His anecdotal evidence seems to be falling flat this year. The winter of 2009-2010 is already the snowiest in D.C. history, with more than five feet measured already at Dulles Airport. Not only that, but we’re expecting 10 to 20 inches of snow tomorrow.
None of this disproves the idea of anthropogenic global warming. But neither does Kennedy’s vague memory of colder times prove anything.
