I see the bigger problem being the huge melt offs that seem to be bigger and more frequent. Notice I said seem, I don’t have any hard data close at hand to prove or disprove that thought. Also on the anecdotal level, deep cold seems less common. And yes, I know we still get some good cold from time to time but -30s don’t happen much anymore. Growing up, it wasn’t uncommon for Canaan, VT to be the coldest spot in the country at least a few times each winter. It may be that there isn’t an observer there anymore or the location has changed but it doesn’t feel the same.
