Google "ice ages" and do some reading. There is a lot of interesting stuff there. Roughly, for 90 percent of the last million years, the earth has been in an ice age. The earth is just now recovering from the last one. The complete cycle is about 100,000 years and the period in between is about 15 to 20 thousand years, so we are 18000 years into the most recent warming trend and are possibly due another. The scary part is the ice age begins abruptly, like just a few years. What happens is polar ice melts and dilutes the salt water that partly drives the big ocean currents (the gulf stream is about 100 Amazon Rivers) that carry the vast amounts of tropical heat to the northern latitudes and keep Canada and Europe warm. If those currents get disturbed or cut off then up to 30 percent of the land mass of the northern hemisphere will be covered in ice. We're talking ice maybe a couple thousand feet deep. The rest of the planet will be cold and dry. The last ice age lasted about 60,000 years. The real cold(?), hard fact is the glaciers are melting. The question is how much man has caused? IMO, a little. A bigger question is, will mankind survive? IMO,yes, but there won't be very many of them when the ice melts.
