New Study: Greenland Was 3-7°C Warmer and Far Less Glaciated Than Today 6000-8000 Years Ago

Approximately 6000-8000 years ago, or when atmospheric CO2 was alleged to be ~260 ppm, PD had deglaciated completely, exposing the soil to sunlight.

A large portion of the Greenland ice sheet that is today over 500 m thick did not exist during the Early to Mid Holocene.

Prudhoe Dome (PD), a 2500 km² section of northwestern Greenland’s ice sheet (GIS), is today 500 to 600 m thick (Walcott-George et al., 2026).

Approximately 6000-8000 years ago, or when atmospheric CO2 was alleged to be ~260 ppm, PD had deglaciated completely, exposing the soil to sunlight.

The primary mechanism for the PD deglaciation was the estimated 3-7°C warmer-than-present regional temperatures. This warming and the consequent ice cap minima was said to be  “Arctic-wide”.

Starting ~4000 years ago the GIS gradually began thickening until it recently reached its modern glaciated state, with glaciation peaking in the 1800s.

Don`t worry there is no significant man- made global warming. The global warming scare is not driven by science but driven by politics. Al Gore and the UN are dead wrong on climate fears. The IPCC process is a perversion of science.
