"Unprecedented", "once-in-a-hundred-years", "biblical" weather events lately, I'm assuming you've noticed. A mile-wide (!) tornado cut a huge path thru Alabama, including Tuscaloosa, killing lots of people. A half-mile wide tornado destroyed Joplin Missouri this past week (May 26 or 27) with 150 people still unaccounted for. More tornados thus far this year than I can believe.
So I am watching CNN this AM, while the anchor sets up the main weather man, Reynolds Wolf, with the question, "Reynolds, why are we seeing all of these tornados?" I dared to think, OK, here we go, he's going to mention climate change! Instead, what did Reynolds say? He said that due to vastly improved technology, we are able to detect and observe many more tornados than used to be possible. Is he suggesting that without technology, we might have missed the mile-wide tornado that killed all of those people in Alabama? But then a commercial came on, and now I think I understand; the sponsor of the CNN news program is the American natural gas industry! The pieces fall into place.
