Some 30 percent of the world’s land was covered in ice, compared with 10 percent today.
Ice covered a lot of the Northern Hemisphere, including Scandinavia, Great Britain, Northern Europe, and Russia. The Alpine glaciers covered much of France, Austria, southern Germany, and Italy.
The Himalayan glaciers moved as far as Siberia. In the Southern Hemisphere, glaciers existed in the mountains of South America, Australia, and New Zealand.
The Antarctic ice spread almost to the tip of South America.
