"Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earths climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming. "
Curent warming compared to an average does not make current warming unprecedented.
