Severe Tornadoes, Per NOAA: Since 1950s, These Extreme Weather Events On Declining Trend
Climate-doomsday cult predictions of CO2-induced extreme climate change have been a common, easy refrain of politicos seeking donations from special interest groups...yet, the empirical evidence provided by NOAA and other climate agencies is simply overwhelming...those much anticipated increases of severe weather events from greenhouse gases are just not happening, including U.S. tornadoes.....

Tornadoes. They're dangerous and they're unsympathetic killers.
These extreme weather events are officially categorized in severity from 'EF0' to 'EF5' - with the higher number being the rarest of the killer tornadoes.
As this chart reveals, the good news for the U.S. is that the categories of severe tornadoes (E2-E5) are on the decline. The declining trends, since the 1950's period of lower atmospheric CO2 levels, are indisputable.
Based on a casual observation, one might conclude that increasing CO2 levels and global warming have curtailed these frightening weather phenomenon. Good!
Ahhh...those stubborn climate facts provided by NOAA are just sooo inconvenient at times, no?
Note: During the 2011 tornado season, there was a strong uptick but since then the severity T-counts have subsided, confirming the longer-term trend. 1950-2013 tornado dataset here. NOAA has not yet published official the 2014 severe tornado counts. Severe tornado counts for 2014 were confimed here, here, here, here, here and here. Above plots and trends produced using Excel.
