The Reference Frame: Gore effect arrives to Harvard University

For tomorrow night, the temperature in Cambridge is forecast to drop below the freezing point to 28 °F which, if true, will beat the record low temperature set in 1883, which means exactly 125 years ago, when it was 29 °F. Not bad! Moreover, the phenomenon present in Cambridge in order to discuss global warming seems to be driving rain and hail, with the probability of rain indicated as 60%. ;-) At 1 p.m. local time, they report a cloudy weather with isolated showers.
