A blog called “Watts Up With That?” uses our record snowfall in Dallas last week as a jumping-off point for discussing mean temperatures in Texas over the past century. The author uses simple line graphs to demonstrate that temperatures in small towns like Dublin or Brenham have barely budged over that time. So where’s your global warming, he asks.
Meanwhile his snapshot for San Antonio shows a clear rise in temperature, all of which he attributes to the “Urban Heat Island” effect. I’m no climate scientist, but when experts mention catastrophic climate change, aren’t they talking about a worldwide spike of even just a couple of degrees on average? Isn’t it incorrect to think that imprecise measures, like these line graphs, of extremely localized temperatures have much bearing on the discussion?
