What did the world look like during the last ice age? Was it all endless glaciers and frozen ice? The answer is a partial yes—with some interesting caveats.
The Last Glacial Maximum (LGM), colloquially called the last ice age, was a period in Earth’s history that occurred roughly 26,000 to 19,000 years ago.
This map by cartographer Perrin Remonté offers a snapshot of the Earth from that time, using data of past sea levels and glaciers from research published in 2009, 2014, and 2021, alongside modern-day topographical data.
