A bunch of people have gathered in Washington DC today to protest global warming. Well, a presumed cause of it: coal burning.
Here are two relevant images:
The lesson is this: climate forecasts might not be that accurate, but 12-hour meteorological predictions are pretty good.
The pictures are not necessarily ironic because, as James Hansen would say and I would agree, global warming only decreases the probability of exceptionally cold and snowy days in March in Washington—it does not eliminate their possibility.
This position is consistent with DC experiencing as many exceptionally cold and snowy days as you like. But their actual occurrence cannot but weaken the evidence for continued global warming.
Not ironic, then. But funny.
