Description:
Since the 2007 Intergovernmental Panel on Climate Change Fourth Assessment Report, new observations of ice-sheet mass balance and improved computer simulations of ice-sheet response to continuing climate change have been published. Whereas Greenland is losing ice mass at an increasing pace, current Antarctic ice loss is likely to be less than some recently published estimates. It remains unclear whether East Antarctica has been gaining or losing ice mass over the past 20 years, and uncertainties in ice-mass change for West Antarctica and the Antarctic Peninsula remain large. We discuss the past six years of progress and examine the key problems that remain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hanna, Edward -- Navarro, Francisco J -- Pattyn, Frank -- Domingues, Catia M -- Fettweis, Xavier -- Ivins, Erik R -- Nicholls, Robert J -- Ritz, Catherine -- Smith, Ben -- Tulaczyk, Slawek -- Whitehouse, Pippa L -- Zwally, H Jay -- England -- Nature. 2013 Jun 6;498(7452):51-9. doi: 10.1038/nature12238.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geography, University of Sheffield, Sheffield S10 2TN, UK. ehanna@sheffield.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23739423" target="_blank"〉PubMed〈/a〉
