It is well known that strong to violent tornado activity in the US has decreased markedly since statistics began in the 1950s, which has also been a period of average warming. So, if anything, global warming causes FEWER tornado outbreaks...not more. In other words, more violent tornados would, if anything, be a sign of 'global cooling,' not 'global warming.'
Roy SpencerWe are now at the point in the age of global warming hysteria where the IPCC global warming theory has crashed into the hard reality of observations.
Roy SpencerBelieve it or not, very little research has ever been funded to search for natural mechanisms of warming... it has simply been assumed that global warming is manmade. Climate change - it happens, with or without our help.
Roy SpencerTemperature measurements in the arctic suggest that it was just as warm there in the 1930's...before most greenhouse gas emissions. Don't you ever wonder whether sea ice concentrations back then were low, too?
Roy SpencerPoliticians and some of the scientists like to say that there's a consensus now on global warming or the science has been settled, but you have to ask them, what is there a consensus on? Because it really makes a difference. What are you talking about? The only consensus I`m aware of is that it's warmed in the last century. They completely ignore the fact that there's this thing called the Oregon petition that was signed by 19,000 professionals and scientists who don't agree with the idea that we are causing climate change.
