Summary: A hundred years ago, Ernest Shackleton set out on his Trans-Antarctic expedition which ended when his ship Endurance became trapped in packed ice. The lure of this polar region remains strong both in our imaginations and in terms of understanding what is happening to the planet. Rana Mitter discusses the Antarctica of our imaginations and the reality of the landscape with writer Meredith Hooper, polar explorer Ben Saunders, architect Hugh Broughton and glaciologist Jonathan Bamber.
