Very similar pattern here (UK): circa 1900, ice skating on the local pond every winter. The ice was thick enough to walk on the pond twice in the 1980s. For the last decade, the pond hasn't completely frozen over once. We got about two days of 30% coverage this Jan.

As a kid (I was born in the 80s), my home town would get 3ft of snow almost every winter. We even saw 10ft some winters.

By the time I hit highschool, seeing a 3ft snow in the winter was pretty rare.

Over the last 4 years, there's never any snow on the ground. They are lucky if 1 inch sticks around.
