There's a good Slatepiece up about GW, but unfortunately, one of its paragraphs says this:
....consider Hurricane Katrina. When it first reached Florida, it was a Category 1 storm. While traveling across the warmer-than-usual surface of the Gulf of Mexico, it brewed itself into a Category 5 then actually weakened to a Category 3 before causing the destruction still so fresh in our minds. Why were the Gulf's waters warmer than usual? You guessed it--and models had forecast this type of change, too.
Memo to writers: Global warming is a *global average change* in temperatures. Talking about that is fine, but attributing the temperatures of the Gulf on a particular week in August to GW is a completely different affair....
