Professor Jason Box was good enough to add some expert commentary to our recent story about a large calving of the Jakobshavn Glacier last month. Consequently we have just watched his presentation to the 2015 Economist Arctic Summit at the Hotel Bristol in Oslo with much interest. Here are our edited highlights from the conference’s Twitter feed:
