The author is ignorant of global warming theory... All things bad are caused by global warming including nasty cold weather.
You are far too modest in your claims about Anthropogenic Global Warming Theory. AGWT explains and predicts all things, both good and bad. AGWT is very robust with respect to data and cannot be refuted: all observations confirm it at the 100% confidence level. The naked casuistry of the high priests of warmism would make a Jesuit blush.
Right on!! AGW enthusiasts have told us that heavier snowfall amounts can be expected because of global warming.
But I believe southern Minnesota (Filmore Co.) has not for a long time experienced snow depths such as I waded through walking to school during the mid-1930s. But I could be in error about that; I moved about 100 miles east into Badgerland in 1940.
