Dr. Roger Pielke on The US National Climate Assessment and Weather Extremes:
Drought: “drought statistics over the entire CONUS have declined … no detectable change in meteorological drought at the global scale”
Hurricanes: “there is still low confidence that any reported long-term (multidecadal to centennial) increases in TC activity are robust”
“IPCC AR5 did not attribute changes in flooding to anthropogenic influence nor report detectable changes in flooding magnitude, duration, or frequency”
In the US “”increasing & decreasing flooding magnitude but does not provide robust evidence that these trends are attributable to human influences… no formal attribution of observed flooding changes to anthropogenic forcing has been claimed"
The data says what it says. There is precious little evidence that extremes have become worse in the US since at least 1900, with the exception of more winter storms since 1950 and overall fewer cold spells. Attribution is weak to nonexistent.
Gore: Man-made global warming caused drought and then upheaval in Syria which led to 'flow of refugees' to UK which led to Brexit vote
Gore: The [Syrian civil ]war broke out in 2011 as people took to the streets during the Arab Spring protest movement against dictators in the Middle East. President Bashar Assad responded by sending in the troops. Mr Gore said this had produced an “incredible flow of refugees into Europe, which is creating political instability and which contributed in some ways to the desire of some in the UK to say ‘whoa, we’re not sure we want to be part of that anymore’”. He said this kind of political instability was being felt by a number of countries around the world. “Some countries have a hard time even in the best of seasons but the additional stress this climate crisis is causing really poses the threat of some political disruption and chaos of a kind the world would find extremely difficult to deal with,” Mr Gore said.
The U.S. has not seen a major hurricane — Category 3 or higher — make landfall since Hurricane Wilma hit on Oct. 24 2005. The nearly decade-long hurricane drought has come as a big surprise to climate scientists and environmentalists who have argued that global warming will make storms more frequent and intense.
