It's a good point. There are 100 or more feet of snow in parts of Alaska that won't melt this summer. It may be that there will be some glacier growth in Europe, although I'm not as sure about that.
There were ski resorts in Colorado last year that stayed open till July 4th. WE were there at the end of May and neither of us had ever seen so much show that late.
I’ve read ice ages can come upon an area in as little as 10 to 15 years. A few severe winters in a row is all it takes.
