Are you OK?
Which would of course be rational. In medieval times there was global cooling. The middle 1760s were so cold that the period is sometimes referred to as "the little ice age" when the Normans invaded Britain (1066 and all that) the climate in the British Isles was warm enough to sustain vinyards.
On a geological timescale we are heading for an major ice age at the moment. But margin of uncertainty means that couple of thousand years one way or the other is insignificant so the ice age could be starting right now or in a few thousand years.
