The West Antarctic ice sheet could cause metres of sea level rise if it collapses – but more than 120,000 years ago, it may have survived an even warmer period than it is experiencing now ...

Led by The Institute of Polar Sciences of the National Research Council of Italy (ISP-CNR), the scientists worked for more than 200 days, drilling into the ice and processing the ice core at a remote ...

An ice core drilled from the ice sheet near the bordering Ronne Ice Shelf suggests that, contrary to some model reconstructions, the ice shelf survived this period at almost its current extent.

One of the best ways to assemble the puzzle pieces of Earth’s past is hiding deep beneath its white polar sheets: ice cores. These frozen time capsules preserve air bubbles from thousands of ...

the researchers measured concentrations of sea salt in an ice core drilled about 650 kilometres away from the shelf’s edge. If the ice shelf had melted during the last interglacial, its edge ...
