Alternate headline? Severe weather not caused by climate change, Al Gore hardest hit. William Teach has the scoop
(Washington Post) The study (abstract): “Monitoring and Understanding Trends in Extreme Storms: State of Knowledge”, to be published in a forthcoming issue of the Bulletin of the American Meteorological Society, states its objective plainly:
Due to the intense media coverage of and great public interest in the 2011 disasters, we suspect that many [meteorologists] have received inquiries or have a personal interest about the nature of these events in the context of long-term trends and potential climate change. This paper is meant to present a clear record that can be used by meteorological professionals about what is known and unknown and why.
What’d they find out?Summary: Good long-term records of thunderstorms don’t exist and there’s no clear physical reason why to expect they would have changed.
Summary: Records of past tropical storm and hurricane activity are likely incomplete. While the frequency of Atlantic storms has increased since 1970 when observations have been more reliable, the cause of this uptick is not agreed upon.
Summary: There’s indication big snowstorms have increased over the last 60 years but no clear explanation for the change. The increase in big snowstorms has occurred even while the number of years with very little snow has stayed the same or increased. And there’s no evidence of meaningful changes in ice storms.
Summary: Reliable data indicate heavy precipitation events are increasing and rising amounts of water vapor in the atmosphere due to human-caused warming offer a good, but not necessarily complete, explanation.
But, the Warmists will still tell us that the science is settled
