WUWT:
From the UNIVERSITY OF EXETER and the “weather is not climate” department comes this press release that comes with a blindingly obvious title. So far, the efforts trying to link “climate change” to extreme weather events usually come up short. Often they come amplified in social media by activists like Bill McKibben who sees climate change occurring behind almost every weather event and uses that as a tool to keep his followers excited and active. But the reality is that extreme weather just hasn’t been on the increase. Hurricane frequency is flat and accumulated cyclone energy has been down, andhasn’t reached levels seen in the 1990’s, US landfalling hurricanes of Category 3 or greater continue in an unprecedented 10 year drought, tornadoes aren’t increasing, in the U.S. at least, heat waves aren’t getting worse, even though activists like to falsely claim so, much of it has to to with urbanization. Droughts aren’t getting worse. Often flooding that is claimed to be worse due to “climate change”, is often a result of poor management, such as what happened in Southwest Britain. In fact, a lot of the ideas that extreme weather is becoming worse are little more than a bias due to increased reporting of 27/7 news outlets.
Even the IPCC says in their SREX report ( IPCC Special Report on Extremes PDF) that with the exception of some warmer days and night and rainfall that “may” have been exacerbated by slightly warmer global temperatures, they can’t make any clear link to other type of severe weather, expressing “low confidence” in such linkages. It’s a dead issue.
Finally, it’s instructive to remember this editorial from Nature that said clearly there’s been no linkage:
