Ice cores tell us vital information about how the world's climate has changed - and how it will change in the future.
Ice core samples storing mysteries from bygone eras.
Ice cores are cylinders of ice drilled from glaciers and ice sheets. When snow falls it takes with it a record of many aspects of the atmosphere. As long as no melting takes place, this information is…
The past, on ice.

How can air bubbles trapped in ice for millions of years, or fossilised fern fronds, or the chemical make-up of rocks that were underwater in the distant past provide us with an inkling of our future…
By studying ice cores, researchers can measure the methane emissions from thousands of years earlier.
The past is the key to the future. When snow falls on polar ice sheets, in Greenland and Antarctica for example, air is trapped between the snowflakes. Year after year, the snow compacts under its own…
A 364-metre-long ice core record has revealed an unusual pattern of rapid warming across the Antarctic Peninsula over the…
