I'm Not Sure the Data Means What You Think It Means
Over at Climate Skeptic, I discuss a recent claim by ABC that year-to-date tornado frequency has nearly doubled vs. 2007, and that this is because of global warming. I will take their word for it that tornado frequency is up, but there is one tiny problem: The US in Jan-Apr of this year was almost a full degree cooler than last year. So if tornado frequency is up, and ABC is correct that yearly changes in this metric are due to changes in global temperature, then it can only mean that global warming reduces, rather than increases, tornadoes.
