Glaciers FAQs - 29 Found
The Last Glacial Maximum (LGM) occurred about 20,000 years ago, during the last phase of the Pleistocene. At that time, glaciers covered:
~ 8 % of Earth’s surface
~ 25 % of Earth’s land area, and
~ 33% of Alaska
During the LGM, global sea level was more than 400 feet lower than it is today.
Following the LGM (beginning ~ 15,000 years ago), continental glaciers retreated and sea level began to rise. By ~ 8,000 years ago sea level reached its current height. It has fluctuated ever since.
Today, glaciers cover:
~ 3.1 % of Earth’s surface,
~ 10.7 % of Earth’s land area, and
~ 5 % of Alaska.
