37. Ummm... not at clear-cut as you think.

"Fortunately, human-warmed climate isn’t making violent U.S. tornadoes any more frequent. However, climate change may be involved in some noteworthy recent shifts in the location and seasonal timing of the tornado threat.

The total number of U.S. tornadoes observed each year roughly doubled from the 1950s to the 1990s with the advent of more storm spotters and chasers (think “Twister”). Most of these “extra” tornadoes were on the weak side, though, as the more intense ones were already hard to miss. The boost provided by more eyes and cameras largely disappears when the count turns to only the 300 to 600 tornadoes per year rated at least EF1 on the Enhanced Fujita Scale (or F1 on the original scale) with top wind gusts of at least 86 mph, ignoring the forgettable “EF zeroes” (EF0s).

Each tornado is a localized creature, which makes it difficult to link to global climate trends. Climate change typically plays out in local fashion by way of broad regional shifts, such as depleted sea ice, warmer oceans, and drier landscapes. Sometimes these shifts are distinct enough from natural variation to signal clearly that human-caused climate change is likely involved. In contrast, tornadoes and their parent thunderstorms are brief and episodic, and they normally vary a great deal over time and space, so it’s tougher to distill long-term trends in their behavior and distinguish those from normal ups and downs.

Nevertheless, a few signals have shown up in tornado seasons over recent decades. Some may be the result of year-to-year or decade-to-decade variability; others could be related to longer-term, human-caused climate change. Here’s what scientists have been noticing.
