The core is nearly as long as 25 soccer fields end to end or six and a half times taller than the Empire State Building .

It is a “time machine” that captures “an extraordinary archive of Earth ’s climate,” researcher says.

The core was collected from Little Dome C , one of the harshest and most extreme locations on the planet.

Each meter of ice can contain as many as 13,000 years of climate data.

Ice cores contain layers of snowfall that have been compressed over time.

They could help scientists understand how Earth ’s climate has behaved in the past to better predict how things may change in the future.
