The Altithermal Period consisted of an increase of 4°C near the North Pole, North-Western Europe experienced warming while it was cooling in the South, the change in mean temperatute seems to have diminished rapidly with the latitude so that essentially no change in the mean temperature was reported at low and middle latitudes.

This event led to the melting of the glaciers of the North Pole, with the consequent rise in sea level. In addition, rainfall increased, which also increased the number of forested areas.
