Scientists estimate the average global temperature the Last Glacial Maximum (19,000-23,000 years ago) was about 6 degrees Celsius colder than the average global temperature of the 20th Century - the technique involved analyzing the preserved fats of fossilized marine plankton User stereomatch, in the Reddit Science subreddit, 29 Aug 2020
Glacial cooling and climate sensitivity revisited - global mean cooling of about -6.1°C during the Last Glacial Maximum, implying a climate sensitivity of about 3.4°C for a doubling of CO2 concentration User silence7, in the Information about the world's climate subreddit, 26 Aug 2020
