Earlier this week, Rush Limbaugh and other conservative commentators made light of the fact that the announcement of the creation of a new federal climate service on Monday had to be conducted by conference call, rather than news conference, because the federal government was shuttered by the storm.

Matt Drudge, who delights in tweaking climate-change enthusiasts, noted on his Web sitethat a Senate hearing on global warming this week was canceled because of the weather.

As the first blizzard howled last weekend, the Virginia Republican Party put up an advertisement on the Web — titled “12 Inches of Global Warming” — criticizing two Virginia Democrats, Representatives Rick Boucher and Tom Perriello, who voted for the federal cap-and-trade legislation last year. The advertisement urges voters to call Mr. Boucher and Mr. Perriello to ask if they will help with the shoveling.
