This whole "the winter was cold, global warming must be a lie!" nonsense has been around for longer than I've been alive, and I think it's a consequence of outright distrust of the scientific establishment. Don't you think the "lie" of climate change would be the scoop of the century for a scientist? Do you think that all the world's scientists are conspiring together?
A quick google search would bring up plenty of scientific literature about why global warming causes more extreme weather events. This past February (and several of the last winters) there have been incidents of instability of the polar vortex which are directly linked to the melting of the polar ice caps. Those areas get hot (in recent years, over 90 degrees Fahrenheit) and it blocks out the cold air [1]:
> While the polar vortex is well documented, its behavior has become more extreme as a result of climate change, according to Ullrich. He explains: warming of the Earth has led to the loss of Arctic sea ice, transforming a highly reflective icy surface to a dark absorptive surface. The change is warming higher latitudes and reducing the temperature difference between the warmer mid-latitude and polar regions. This weakens and destabilizes the polar jet stream, causing it to dip into lower latitudes, bringing polar air farther south. Ullrich expects future climate change to further weaken the polar jet stream, bringing rise to more extreme and unusual weather patterns.
