There’s a good Slate piece 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….
