Ralph B Alexander posts at the UK Global Warming Policy Foundation: "This report discusses the lack of scientific evidence for the popular but mistaken belief that global warming causes weather extremes – a notion hyped by the mainstream media and believers in the narrative of human-caused climate change. If there is any trend at all in extreme weather, it’s downward rather than upward. Our most extreme weather, be it heat wave, drought, flood, hurricane or tornado, occurred many years ago, long before the carbon dioxide level in the atmosphere began to climb at its present rate."
