La Nina currently underway, with a strong Hudson Bay low established, is giving us the prospect of a continued severe drought in the US Southwest, maybe even into the US Northwest margins perhaps.
In my theory, this setup has the potential of years length, with above average Gult of Mexico/Caribbean and mid-Atlantic surface temps, which we've seen this year as capable of supporting a lot of moisture being fed up the Mississippi valley. This is some of the scenario I've been trying to describe as feeding the development of a huge ice sheet around the Hudson Bay, and the start of a new Ice Age.
Only, imo, the seas aren't really warm enough to sustain it very long.....
Along with the huge ice sheets in the Great Lakes/Hudson Bay region, the last Ice Age supprted lakes filling all the Western USA basins. Lake Lahontan/Lake Bonneville, and even lakes in the Mohave Desert region, as we term it today, which some believed were host to significant human cultures.
