Why the link between tornadoes and climate change is hard to draw : NPR

Dozens of tornadoes — including one massive storm that tore through more than 200 miles — struck Kentucky, Tennessee, Arkansas, Illinois, Missouri and Mississippi on Friday and Saturday, killing at least 14 people in four states and People following the devastating news out of the region may be wondering: (How) was the storm related to climate change? After all, most of the extreme weather events that have dominated headlines recently — from The same can't exactly be said for tornadoes, however. Scientists know that warm weather is a key ingredient in tornadoes and that climate change is altering the environment in which these kinds of storms form. But they can't directly connect those dots, as the research into the link between climate and tornadoes still lags behind that of other extreme weather events such as hurricanes and wildfire. That's at least in part due to a lack of data — even though the U.S. Other factors that make that climate change attribution difficult include the quality of the observational record and the ability of models to simulate certain weather events. The National Oceanic and Atmospheric Administration says that's the case with tornadoes. "The observational record is not consistent and relatively short, the models remain inconclusive as to replicating tornado activity, and While scientists may not be able to conclusively connect tornado frequency or intensity to human-caused climate change, they say there are signs pointing in that direction. Here...
