Interview: Henry Worsley of the 2008 Shackleton Centenary Expedition (Antarctica)

[Q:] The controversy of global warming in the press has many people confused as to what global warming is and if it really needs to be a concern. What would you say to the doubters in regards to this topic?

[A:] I hope that the doubters are correct. I fear that they are not- only time will tell. But it will be of significant global concern if sea levels rise. When Shackleton set off from his hut on 29th October 1908 he walked out over the sea ice towards the Ross Ice Shelf. One hundred years on, we might not be able to do that because the same area is often underwater at the same time of year. So, in only one hundred years simple but dramatic changes are taking place.
