Antarctic Glaciers Don’t Grow Slowly—Some Are Among the World’s Fastest

Contrary to the premise, glaciers in Antarctica can flow extremely quickly. The Jakobshavn Isbræ (in Greenland, often cited for speed) reaches 40 meters per day, but Antarctic outlet glaciers like Pine Island and Thwaites also move rapidly due to thick ice and gravitational forces. The cold climate preserves ice, but it doesn’t slow flow; immense weight drives fast movement.
