Due to the incredibly bad reporting by the mainstream press, many Americans believe the U.S. suffers from "accelerated warming" and increasing severe weather - neither are true
First, as the adjacent chart reveals, U.S. temperatures are not "accelerating." The red curve is the 12-month moving average (since 1895), which clearly shows no acceleration, and shows zero relationship to the growing levels of atmospheric CO2 levels (black dots).
As can be seen, U.S. monthly temperatures have a wide variation (the blue up/down plot) in any given year, fluctuating between low and high extremes.
Again, no "accelerating" warming trend is evident from the actual temperature empirical evidence. (click on charts to enlarge)
Read here. This second chart plots the total number of severe tornadoes (F2, F3, F4 & F5) in decade groups (the 2000's include 2011). This actual empirical evidence substantiates that severe weather events, as represented by extreme tornadoes, are not increasing in the U.S.
Conclusion: The mainstream press (eg., NYT, WaPo, Time, CBS, NBC, LA Times, etc.) willfully and unequivocally reports misinformation regarding severe weather and global warming. They do so to purposefully mislead the public and policymakers regarding global warming and climate change.
