New ice core data from the Antarctic Peninsula has revealed that temperatures in the region during the past 10,000 years have often been higher than they are today, and that warming of the sort seen there recently has also occurred in the pre-industrial past.
The new data are derived from a massive new 364m-long core extracted from the ice sheet lying on top of James Ross Island towards the northern tip of the Antarctic Peninsula in the freezing Weddell Sea.
The core was extracted by scientists from the British Antarctic Survey, assisted by French boffins, who reached the area courtesy of the Royal Navy ice-patrol ship HMS Endurance and her helicopters.
