A new paper from the Global Warming Policy Foundation (GWPF) reveals that there has been no increase in global hurricane activity, despite frequent claims that global warming is making hurricanes more of a problem. As the report’s author, Paul Homewood, explains: “The theory is that rising sea-surface temperatures should make hurricanes more frequent or more intense or both. But observational data shows that there is no empirical evidence to support the theory.” This is because most records of hurricane activity show no long-term increases, either in total numbers of hurricanes or of the most intense ones.
Climatologist Dr.Roy Spencer on Allstate's ad hyping 'once in 500-year storm' frequencies: 'I consider this false advertising because Allstate knows better, and is purposely misleading the public to make more money...Allstate knows better (the insurance business deals with probability and statistics) and they knew this was a lie when they put the ad together.'
Real-world observations contradict Mann’s claims: Dr. Mann claims that “it’s not rocket science” that global warming has led to “unprecedented” extremes in droughts (too little precipitation) and floods (too much precipitation). He insists that we must take “concerted action” to mitigate our use of fossil fuels so as to avert these “disastrous” and “devastating” extreme weather consequences. Mann classifies those who disagree with him about the link between AGW and these extreme weather events as “climate deniers”.
