Caution: It is vitally important not to make connections. When you see pictures of rubble like this week’s shots from Joplin, Mo., you should not wonder: Is this somehow related to the tornado outbreak three weeks ago in Tuscaloosa, Ala., or the enormous outbreak a couple of weeks before that (which, together, comprised the most active April for tornadoes in U.S. history). No, that doesn’t mean a thing.

It is far better to think of these as isolated, unpredictable, discrete events. … But do not wonder if they’re somehow connected.

If you did wonder, you see, you would also have to wonder about whether this year’s record snowfalls and rainfalls across the Midwest — resulting in record flooding along the Mississippi — could somehow be related. And then you might find your thoughts wandering to, oh, global warming, and to the fact that climatologists have been predicting for years that as we flood the atmosphere with carbon we will also start both drying and flooding the planet, since warm air holds more water vapor than cold air.

Diane Sawyer also suggestively mused, “Is this it, this is the evidence of a kind of preview of life under global warming?”

Yet as I previously highlighted, actual scientists have said there is no evidence to connect these storms to any supposed warming:

A top official at the National Oceanic and Atmospheric Administration (NOAA) rejected claims by environmental activists that the outbreak of tornadoes ravaging the American South is related to climate change brought on by global warming.

Greg Carbin, the warning coordination meteorologist at NOAA’s Storm Prediction Center in Norman, Oklahoma, said warming trends do create more of the fuel that tornadoes require, such as moisture, but that they also deprive tornadoes of another essential ingredient: wind shear.

“We know we have a warming going on,” Carbin told Fox News in an interview Thursday, but added: “There really is no scientific consensus or connection [between global warming and tornadic activity]….Jumping from a large-scale event like global warming to relatively small-scale events like tornadoes is a huge leap across a variety of scales.”

With this latest tragic disaster, Carbin has now been forced to shoot the nonsense down once again, this time by pointing out that there has not even been an increase in tornadoes in 2011, rather they have just hit more populated areas:

Carbin: “There is no indication of an upward trend in either intensity or numbers. We’ve had a lot more reports of tornadoes, but most of those tornadoes are actually the weak tornadoes, the F-0. When you take out the F-0 tornadoes from the long-term record, there is very little increase in the total number of tornadoes, and we don’t see any increase in the number of violent tornadoes. It’s just that these things are coming, and they’re very rare and extreme, and they happen to be hitting populated areas. So right now, no indication of an upward trend in the strong to violent tornadoes that we’re seeing.”

But don’t expect the facts to stop Warmists like Bill McKibben from drawing connections where none exist.
