Antarctica is Earth’s largest desert. Its high interior receives less than 50 millimetres of precipitation a year, almost entirely as snow—and because that snow rarely melts there, thousands of years of meagre snowfall have accumulated into an ice sheet kilometres thick.

1+ week, 1+ day ago   (1525+ words) Antarctica’s high plateau receives less than 50 millimetres of water-equivalent accumulation a year.

In 2025, Antarctic drillers reached bedrock and pulled up ice that fell as snow 1.2 million years ago — roughly 50 percent further back than any ice core had ever reached, with the air of that vanished world still sealed inside the bubbles
