A new study of warming after the last ice age 20,000 years ago confirms climate models that predict an amplification of warming at the poles. By 15,000 years ago, the Antarctic had warmed about 11 degrees Celsius, almost 3 times the average global warming (4 degrees Celsius). The calculations, based on temperature measurements down a 3.4-kilometer-deep borehole, prove that climate models do a good job of estimating past climatic conditions and, very likely, future changes.
