I guess I need to revise my previous fears that my son would never get icy, snowy winters like I did due to global warming to he will get them perhaps even more than I saw due to global warming. Lake Erie hasn't gotten to 100% ice coverage since 1996.

According to GLERL's records, two lakes have frozen over completely: Lake Superior in 1973 and 1996; and Lake Erie in 1978, 1979 and 1996.

We are on track for one of the iciest years ever recorded on the Great Lakes. Pretty wild stuff!
