The importance of ice: Professor Julian Dowdeswell explains extreme climates
Both ice sheets and sea ice are changing rapidly in the polar regions, and the Arctic is widely regarded as the most sensitive part of the global climate system. Professor Dowdeswell, Director of the Scott Polar Research Institute, explored how these changes are likely to affect issues such as global sea-level over the coming century.
Professor Dowdeswell is about to lead the 2019 expedition to try to find the Endurance, the ill-fated ship of Antarctic explorer Sir Ernest Shackleton.
