It's not clearly defined into warming and cooling for a specific spot.
Places that were warm could come cold and the reverse. A sort of bad example
was in the movie The Day after Tomorrow... dumping a lot of freshwater into
the oceans could trigger a cooling trend, thus an ice age.

Facts: The earth has been around for quit a while. The earth warms and
cools in cycles. We MAY be heading into a warm cycle. It probably
doesn't have anything to do with humans. I'd rather live thru a warm
cycle than the next ice age.
