The injection of politics into the global-warming hypothesis has made it difficult to know where facts end and falsehoods begin. While alarmists have been blaming their fellow man for every hurricane, tornado and other ill wind whipped up by Mother Nature, science is now concluding that the cause of these damaging storms has nothing to do with human activity.The IPCC has probably looked at the data that show extreme weather events are diminishing. For an example, this post by Steve Goddard on Real Science. See also NOAA graph below on the number of Strong to Violent Tornadoes.
The surprise absolution of human beings from the crime of triggering severe weather phenomena was handed down by none other than the United Nations Intergovernmental Panel on Climate Change (IPCC), leader of the campaign to sell the world on anthropogenic climate change (AGW).
We can only hope so, but don't hold your breath.The IPCC’s Special Report on Extremes, released March 28, reads, “There is medium evidence and high agreement that long-term trends in normalized [property] losses have not been attributed to natural or anthropogenic climate change.” The breathtaking admission is a sign that objective science is reclaiming a leading role in the discussion.
However, climatologists who stick to facts say otherwise. Roger A. Pielke Jr., a professor of environmental studies at the University of Colorado, notes that globally, hurricane wind speed - an indicator for the amount of energy in the atmosphere - has remained steady for the past 15 years. Accordingly, there is no evidence that weather extremes are on the rise globally, much less that they’re increasing because of human activity.
