No, don't you see? This freakishly cold weather IS because of global warming! You just don't understand the convoluted science!
Of course, the theory there is that the ice caps will melt, cooling the oceans, leading to colder weather for some areas. That that hasn't actually happened won't stop them from using the "you don't understand the wide-ranging effects" argument.
