- tornadoes for 2011 thru April 30 SPC/NWS
If we keep getting "extreme" weather events with this frequency, we'll have to start calling them "routine." Take a look back at April: It set a preliminary record of more than 850 tornadoes, including the April 14-16 "outbreak" that killed 34 and the April 27 "super outbreak" that has taken more than 350 lives. With each episode, the question comes up, "What is causing this?" Is the climate changing? Is the uptick in extreme weather a function of global warming?
Before I discuss these subjects, let’s take a look at the extent of the record "super outbreak" of April 27. There have been other super tornado outbreaks throughout history, such as the one in April 1974 that resulted in 335 fatalities. But the death toll from the terrible EF 4 and 5 tornadoes that had paths close to 100 miles long is now more than 350. This now makes April 27, 2011, the second-deadliest day for tornadoes in history for the United States. Unfortunately, there will be more massively deadly tornado outbreaks in the future. With populations growing in tornado-prone areas, there is an increasing risk of future outbreaks causing loss of life. Even with all the radars, precise tracking and advance warning we have now, April 2011will be No. 1. as the month with the greatest loss of life from tornadoes. Now over 400 fatalities.
As the tornadoes in mid-April were sweeping across the South, snow was spreading across the upper plains, Texas was/is suffering a prolonged drought and the last of some record snows were melting in northern New England after another brutal winter. What is going on with the weather? This must be because of climate change – correct?
