Al Gore was at Harvard yesterday to deliver a sermon on the perils of a warming planet — and, right on schedule, Cambridge was hit with unseasonably cold temperatures. Three thousand of the world’s top scientists agree: the Gore Effect is real.

Here’s the message from the office of Harvard’s president (via Planet Gore’s favorite Pilsener, Luboš Motl):

Dear Members of the Harvard Community,
Although today’s weather will hardly remind us of the serious problem that is global warming, today’s event — the Harvard Sustainability Celebration, with a keynote address by former Vice President Al Gore — will go on, as scheduled, in Tercentenary Theatre with a program beginning at 4 p.m. We very much hope that you will attend and enjoy the festivities.
Starting at 3 p.m., we will be serving hot cider and soup to keep everyone warm; please dress for our changeable New England weather. Henry Longfellow, onetime Harvard professor and longtime Cantabrigian, once remarked, “The best thing one can do when it’s raining is to let it rain.” We sincerely hope that, this afternoon, it won’t rain. But even if it does, Harvard celebrates Sustainability with spirits undampened.
Sincerely,
The Sustainability Celebration Committee
Office of the President

No doubt if it had be 85 degrees, we would have had heard a very different message.
