The map details the extent of ice coverage, showing major ice sheets and dry land areas that are now submerged. Here’s what the map says: COLDER TIMES Approximately 20,000 years ago, this is what our planet looked like.
A map of the Earth 20,000 years ago, at the peak of the last ice age, when colder temperatures transformed the planet we know so well.
A map of the world during the Last Glacial Maximum During the LGM, valley glaciers in the southern Andes (38–43° S) merged and descended from the Andes occupying lacustrine and marine basins where they spread out forming large piedmont glacier lobes .
This map shows how the world may have appeared during the Last Glacial Maximum, around 21,000 years ago, when sea levels were approximately 125 meters (410 feet) below present and the ice sheets were at their greatest extent.
The end of the last glacial period, which was about 10,000 years ago, is often called the end of the ice age, although extensive year-round ice persists in Antarctica and Greenland. Over the past few million years, the glacial-interglacial cycles have been "paced" by periodic variations in the Earth's orbit via Milankovitch cycles .
These maps show the rate at which the ice sheet over the British Isles during the last Ice Age melted. A set of maps created by the University of Sheffield have illustrated, for the first time, how the last British ice sheet shrunk during the Ice Age.
This map depicts the Earth during the last ice age, specifically the Late Glacial Maximum (roughly 14,000 BCE) when the climate began to warm substantially. With so much of the planet's water tied up in ice, global sea level was more than 400 feet lower than it is today.
During the last ice age, the sea level worldwide was over 400 feet (122 meters) below the current level, and glaciers extended over about 8% of the planet's surface, which is equivalent to 25% of the total land area.
Last glacial maximum (LGM), the most recent geologic interval, which spanned 29,000 to 19,000 years ago, in which the geographic extent of ice sheet and glacier coverage on Earth’s surface peaked. Some 8 percent of the planet’s total surface was covered in ice, and sea levels were approximately 125.
