Well Homo Sapiens has been around a long time, at least 1 Pole Reversal. There was a magnetic field excursion ~ 40000 years ago (field strength went to near zero, poles did not flip). Will things get cold next 60 years we will see? I'm worried about the increased cosmic radiation as our magnetic field decreases and from the low solar activity. Folks at equator won't have to worry but us high Latitude and altitude folks will. If you are worried about cold watch the Canadian grain planting times to see if they get later and later. Far as oil 0w20 all the way.
