There are certainly some differences from the late 70s/early 80s, but that seems to have been an unusually cold/snowy period. The overal temps, at least in the northeast, have been stable for about 13 years, so unlikely to see much change in the near future.
Some of the best ice conditions are after we get lots of snow melt and then everything re-freezes.
We might be entering a colder phase globally that may last 10-30 years based on sun spot activity changes. We'll see. I'm told that the last time the sun spots were this low, during a period that should be rapidly building, we entered the "Little Ice Age" in the late 1600s. Smike is feeling it.
I forgot to add that there was significant Volcano activity that added to the changes in the late 1600s.
