From time to time, we get famous speakers at Cambridge. Yesterday brought us Anthony “The Mooch” Scaramucci–President Trump’s briefly tenured communications director. The Mooch had some low points. When asked about climate change, Scaramucci claimed that the phenomenon is 60% human caused, but 40% caused by “natural cycles” which affect “the earth’s position relative to the sun.” This drew audible laughter from the audience. I learned in middle school about the Milankovitch cycles–the problem for the Mooch is that they take tens of thousands of years and move much too slowly to account in any significant way for changes in the climate that occur over just a couple hundred years. But while the man has his flaws, he did make one point that bears repeating–for some reason, it’s still okay in American politics to pick on Italian-Americans.
