These posts discuss various aspects of Climate Change and how it impacts glaciers and ice sheets
Occasionally, comments on this website call me reticent. I think that this is because I try not to let my personal opinions cloud my professional, scientific judgement. I am proud to be reticent. I always try to be informative, to give values of uncertainties and ranges and assessments of confidence. I try to present both …
As the 2013 year draws to a close, I thought it would be great to highlight some of our most important science discoveries in Antarctic Glaciology. Enjoy!

Sea ice and ice shelves What is sea ice? Sea ice is frozen sea water; it perennially expands and contracts during each year’s winter and summer. Amongst the sea ice are icebergs calved from tidewater glaciers and ice shelves. Melting sea ice does not contribute directly to sea level rise (ice floats and displaces the …
A new paper in Nature Climate Change by Bamber and Aspinall attempts to untangle the thorny problem of how quickly and how much the ice sheets of the world will melt. The rate at which ice sheets melt is difficult to understand, because there are many processes that occur.
How much ice is there in Antarctica? And if it were to melt, how much would global sea levels rise, and how quickly?
The Arctic’s sea ice extent reached an all-time low in September 2012, with the smallest recorded extent since satellite observations began. At 3.42 million square kilometres, it may still sound large, but this small extent of Arctic sea ice could have profound long-term consequences, and it follows a long trend of low sea ice conditions. …
In this new website, www.greenlandmelting.com, you can browse maps of the surface melt on Greenland in each year from 1979. You can also look at years with extreme melt events, such as 2010 and 2011.
Proving Climate Change When reading the New Scientists’ focus on Climate Change, I was struck by the number of comments along the lines of, ‘This is theory, we won’t believe it until you prove it’. Two things came to my attention. Firstly, that climate change has been accorded almost myth or religious-like status, and has …
