Al Gore, Barack Obama, NASA and the United Nations Intergovernmental Panel of Climate Change, all agree, global warming is driving climate change, which manifests itself in extreme weather. So let's see what's been going down the last few springs.
In 2012 tornado activity was uncommonly low.
In 2013 tornado activity was even lower yet.
And so far in 2014, tornadoes are down even more.
Thanks for the warnings and your prescience guys! Global warming isn't science, it's a religion, as practiced by a proselytizing, bombastic, brainwashing sect.
