We've gotten a couple of emails, from some overseas fans, asking if we're all okay in the wake of Hurricane Ike. Thanks for your concern, and the short answer is: yes. In fact the storm avoided Austin entirely, except for a light shower that popped up at about 11:30 last night and went away just as quickly. After slamming Galveston, Houston and Beaumont, Ike's remnants shuffled on up the Texas/Louisiana border. My parents live in Jefferson, about a 45-minute drive from Shreveport, way up in what's called the ArkLaTex, that area where the three states meet. They reported fairly heavy rains, really heavy winds (an entire oak blew down at their lakehouse), and a power outage that lasted until about 4:30 this afternoon and even affected other nearby towns like Marshall and Longview.
Last weekend when I was on the show, someone called in asking some vague question about the severity of hurricanes lately, and I pointed out that this was a pretty clear sign of global warming, as it's the function of hurricanes to act as a heat sink, channeling excess heat from the equatorial regions towards the poles. So if you have more heat sending more evaporation into the weather systems, presto, big hurricane. My use of the word "function" got the knickers of one viewer in a twist, who felt that word was inappropriate to use when referring to a natural phenomenon. Well, "function" can be used that way, and does not imply that the thing in question was designed, nor does it impart any teleological purpose to it. Basically he was in the mood to gripe about semantics that day, I guess. Not to say that's an invalid gripe, as people frequently will misrepresent the intent of words in conversation. After all just look how enthusiastically creationists distort the words of Gould and Dawkins. It's practically a sport. Still, I don't think too many people were confused about what I meant when I was discussing the function of hurricanes.
