The end of the last major ice age is evident ~18,000 years ago. Since the current interglacial peak ~6000 years ago, the ice core data show Antarctica has cooled. Ice core data from Greenland also show cooling over the past 8000 years. Doomsday news reports and the IPCC have claimed that rising CO2 will cause a 4°C increase and that the earth has not experienced temperatures 4°C higher than the present over the last 55 million years. Alarmist scientists have claimed a 4°C temperature rise would "change the world beyond recognition", cause the Saharan desert to stretch into Europe, mass extinction, all rivers to dwindle to a trickle, etc., none of which occurred with 4°C higher temperatures 130,000 years ago.
