Probably because there isn't anything to be seen. There isn't solid evidence of a long term move to more extreme weather. There have been killer tornadoes for far longer then there has been any people to be killed by them, and they have been of similar frequency to their number today, for as long of period of time as we have good data for. Yes the total detected tornado numbers are up, but we are better at detecting them now. The more powerful tornadoes (which are more likely to have been detected even with less detection infrastructure and less advanced technology) are if anything on a downward trend (although not one that I would consider significant. A slight trend, over only half a century or so, is hardly enough to say that such a decline is likely to continue, its probably just not enough time to filter out all the randomness in the data, still a slight downward trend does show that there isn't an upward trend . ncdc.noaa.gov Also see coyoteblog.com
