The earth has been getting warmer ever since the last ice age, which probably was caused by a catastrophic event, e.g. an asteroid that kicked up enough dust to substantially cloud the earth and shield it from the sun, cooling it, also causing all sorts of plant matter to die from lack of sunlight and thereby starving all sorts of animal life, too. At the same time, polar icecaps formed and grew.

As the sky cleared, the earth started warming -- over tens of thousands of years -- and the huge polar icecaps that formed during the ice age started melting.

We live in what amounts to a pinpoint in time during the melting phase. It will take a LOT longer. But another asteroid could hit and start the process all over again. If so, I hope you've paid your heating bill.
