Last month was something cold, the Washington Post reports—real cold. A full three degrees chillier than normal and probably the coldest January in a decade. It might be difficult to believe today, with the temperature expected to crest a balmy 54 degrees, but the District isn’t past the worst of it yet. With ice still lingering from the last frost, the city can look forward to more snow tomorrow evening. Still, with one above-freezing day, February is already looking good in comparison: In January, the temperature only climbed above freezing twice. Sorry, Mr. President, but that’s plenty reason to get upset. That’s reason to start writing giant solar heat reflecting screens into the stimulus. That’s reason to move.
