US Scientists: No Evidence "Global Warming" Cause for April's Extreme Weather

"Global warming" is now "climate change" -- a politically corrected statement. And, of course, we always have climate change.

U.S. scientists also looked for the fingerprints of global warming and La Nina on last month's deadly tornadoes, but couldn't find evidence to blame those oft-cited weather phenomena.

And then this:

NOAA research meteorologist Martin Hoerling tracked three major factors that go into tornadoes — air instability, wind shear and water vapor — and found no long-term trends that point to either climate change or La Nina. That doesn't mean those factors aren't to blame, but Hoerling couldn't show it, he said.

Climate models say that because of changes in instability and water vapor, severe thunderstorms and maybe tornadoes should increase in the future. But it may take another 30 years for the predicted slow increase to be statistically noticeable, said NOAA research meteorologist and tornado expert Harold Brooks.

Meanwhile for the next 30 years politicians will continue to talk as if there is man-made climate change.
