Next week on Friday (11 December), 7 p.m. Central Time, the University of Texas-Austin will present a live Webcast of “Global Warming—Lone Star Impacts,” a lecture by Gerald North ofTexas A&M.
It should be an interesting occasion, not just because North is an experienced scientist and climate change is a hot topic, but also because of the timing. The lecture was supposed to be delivered this past Friday, yet an unseasonable snowstorm got in the way. Ah, the inconvenient truths of climate: day-to-day weather can be uncooperative.
As SciGuy blogger Eric Berger for the Houston Chronicle observes: “What does snow falling in Houston have to do with global warming? Nothing. Nada. Zip.” For emphasis, Berger also posted a great photo from a record Houston snowfall in 1895, not to be missed by history buffs.
Friday’s storm across the Gulf Coast delivered the earliest snow on record for Houston–but just five years ago the region had a Christmas snowfall with depths of up to 13 inches.
Fortunately this week’s snow was lighter, but if you’re interested in a detailed perspective about how Gulf coast snow mechanisms can be surprisingly prolific and yet quite “ordinary”, check out the poster by Ronald Morales presented at the 2007 AMS Conference on Mesoscale Processes. It’s full of vivid satellite and radar imagery from the 2004 storm, as well as this overview of the snowfall.
