In the same place where I live now, when I was young there was permanent snow cover for 3 to 4 months.
During the last 10 years, there have been years with no snow and in the others a little snow has been present for 3 or 4 days of a year, when it melted the second day after falling.
I have not used again my winter boots and my winter jackets for the last 15 years or more.
This is really a huge change during less than a human lifetime.
