I had read this novel in the late '90s. It may have been titled Ice or atleast it was mentioned on the front cover. I remember only a few fragments. The Arctic ice has melted away resulting in vicious cold weather systems over North America. Vast areas are under a thick cover of snow. Polar bears and reindeer in lower Canada. The lead character(based in NY?) is very handy with gadgets. He works with a radio and tries to find other survivors. He believes that its still possible to restore civilisation as it was before. His wife along with some other people start to live like Eskimos hunting reindeer, wrapping animal skins around themselves etc. Right at the end the wife deserts her husband(or perhaps kills him).
