9. The polar ice sheet retreated to its current level without human influence.

The one to two mile thick ice sheets melted in only 10,000 years and are still gradually receding, with periodic advances and retreats, due to the natural warmth of the interglacial period. More ice, if not all, probably melted during the last interglacial period of 100,000 plus years ago when Earth's temperature was 5° Celsius warmer and sea level was 19 feet higher although this previous interglacial melting probably took thousands of years to complete.
