400,000 years ago – All of Greenland Melted – No SUVs

The interglacial ~400,000 years ago was lot hotter. And there were no SUVs or coal power plants.

“A paper published … in Palaeogeography, Palaeoclimatology, Palaeoecology finds that the last 4 interglacials were up to 3C warmer than the current interglacial and were characterized by sea levels up to 79 feet [24 meters] higher than the present. According to the authors, “The most conservative estimates of palaeo-sea level during [the interglacial ~400,000 years ago] would require an ice mass loss equivalent to all of the modern Greenland and West Antarctic ice sheets; the more extreme estimates would require additional ice mass loss from the East Antarctic ice sheet.”

Thus, during prior interglacials, sea surface temperatures were up to 3 °C warmer, sea levels were up to 79 feet higher than the present, and up to all of the Greenland and West Antarctic ice sheets melted away. All of this occurred naturally and at “safe” levels of CO2. Thus, there is no evidence that climate change within the present interglacial is any different, unprecedented, unnatural, unusual, or due to man-made CO2.”
