The record old that has hit the US isn't unexpected, and actually fits the trend of winter cooling for the regions hardest hit. What is a bit different is this cold is so widespread and extreme that it actually is leading to less snowfall for many areas.
It snowed again in the Sahara
1. The two-week cold outbreak in the northeastern U.S. and southeastern Canada was highly unusual in the current climate; however, it is not unprecedented.2. Cold waves like this have decreased in intensity and frequency over the last century, but still occur.3. Temperatures like these are now about fifteen times rarer. This is equivalent to cold waves being about 4ºF (2ºC) warmer than they used to be.SummaryOver the last week of 2017 and first week of 2018, a cold wave gripped the northeastern U.S. and southeastern Canada, with temperatures over 18ºF (10ºC) colder than is typical at this time of year over this area, setting records at many sites. We show that the temperature of North American cold waves has increased substantially over the last century due to global warming. So, although this cold spell would not have been unusual before global warming, it is now a relatively rare event in any one region. The chance of a cold wave anywhere in North America is much larger than in this specific location. We do not find any evidence for an intensification of these types of cold waves due to the Arctic warming faster than the midlatitudes. On the contrary, they seem to be warming faster than the winter mean as the Arctic air coming south is less cold now.

The cold kills the bugs that eats the trees! How can you have any pudding, if they don't eats the trees?

No you moron, there is no such thing as global weather. There is also no such thing as a global temperature, or climate.
It snowed again in Florida, while Russia seems to have broken the all time record (again) for the coldest temperature measured at a weather station.
When you see the tell it means you won the argument.
