Probing Earth's last warm phase
Scientists now have a fuller picture of what happened at the poles during the last warm phase on Earth.
Known as the Eemian, this time period extended from roughly 129,000 years ago to about 116,000 years before present.
The poles were known to have been a few degrees warmer than they are today.
Emilie Capron, from the British Antarctic Survey, told our correspondent Jonathan Amos how she used ice and marine sediment cores to extend our understanding of the Eemian.
