Tornadoes, climate change, and real scientific literacy

The air grows thick. Dark clouds churn like a pot of boiling water overhead. The colors of reality become oversaturated--greens too green, yellow a sickly gold. This is what tornado weather looks like, and the United States has been hit with a lot of it lately. Make no mistake, the past two months don't just seem to be particularly twister-laden. This isn't one of those situations where an increased awareness of what's happening outside our own home states has made an average number of tornadoes appear more spectacular. In just five months, the United States has experienced more tornadoes than we often get in an entire year. And far, far more people have died. 2011 is already the deadliest year for tornadoes since 1953. As of May 23rd, 498 people have been killed. That's a big jump from normal. I was born in 1981. In my entire lifetime, annual tornado deaths in the United States have only broken the 100-person mark three other years--1984, 1998, and 2008. Clearly, there is something different about this year. The question is, "What?" The number of tornadoes is simple fact. It's relatively easy to measure. Definitely easy to report. Easy to process and memorize. The reasons behind the numbers, however, are decidedly more confusing....
