Indeed, a glaciation is probable to happen in a period extending to the next ten thousand years, and the fact is that Earth is cooling right now.
Glaciation would be more destructive than the damage any global warming theory predicted, could you imagine Manhattan buried in mile and a half of ice?
Imagine all of the corruption that would be dead and buried too! I hope it gets down to D.C. We need a shot at a do over, IMHO.
