Really, everybody should just calm down and wait a few years. According to the Nat'l Geographic Channel, by then it'll be warm everywhere, all the time. Beaumont will be on the beachfront. Either that, or the next ice age will have begun, and snow skiing in Fredericksburg and LaGrange will be all the rage. The Gulf Stream will move somewhere else, other than where it is now, and they'll be speaking with French accents in Great Britain.
None of this matters, of course, because by then a meteor the size of the Pennzoil Tower will have struck the earth (preferably somewhere near Katy Feeney's office), causing the dinosaurs to come back. Shortly after that, our sun will burn out, at which point I presume it will get really cold. And then MLB will consider scheduling early April games somewhere south of the Mason-Dixon Line.
Like Ecuador.
