john hodgman answers the questions of New Yorkers
This is funny. An excerpt:
I was checking the weather forecast and noticed a three degree difference in the forecast between Manhattan and Brooklyn for Friday (16 degrees for Brooklyn, 13 degrees for Manhattan). Why is this and why would it be warmer in Brooklyn, isn’t it closer to the ocean? Also, on other days there is no difference or a smaller difference. Any ideas?

Actually, Brooklyn’s proximity to the ocean would make it warmer, not colder, for two reasons: a) water changes temperature slowly, thus making coastal cities less susceptible to rapid drops in temperature than mountain cities; and b) sea serpent flatulence.
