The whole hypothesis, that climate can cause a change in weather, is a logical fallacy. Climate after all, does not exist in nature. Weather does. Weather is an independent variable, which can be measured, and the central tendency (average, mean, median,) of that measure is a dependent variable, or outcome variable, climate. An independent variable, weather, is the cause; a dependent variable, climate, is the effect. The climate change cult has it exactly backwards, and has been selling a mirage for years.
Volatility (+/-) is the variable. Volatility affects weather no matter when changes in climate have occurred.
