Prof Edward Hanna of the School of Geography, University of Lincoln, lead-organised an international research workshop on Greenland and Antarctic Ice Sheet mass balance – links between observational data and computer model simulations – as part of the POLAR2018 conference in Davos, Switzerland, on 15 June.
This included some of the world-leading scientists working in this area. There were two keynote talks: Prof Tony Payne (University of Bristol) spoke on “Challenges in making useful projections of the future sea-level contributions of ice sheets”, while Prof Andy Shepherd (University of Leeds) gave a very timely rundown of “Satellite observations of ice sheet mass balance”. The latter talk was based on a major new research paper on Antarctic Ice Sheet mass balance, 1992-2017, that Prof Shepherd had lead-published in the journal NATURE the previous day [as a participant in the second Ice sheet Mass Balance Inter-comparison Exercise (IMBIE2), Prof Hanna is one of about 80 co-authors on this paper].
Other talks included the effects on ice sheets of limiting global warming to 1.5degC above pre-industrial levels by 2100 (an unlikely outcome but one that is highly relevant to study for an upcoming interim report of the Intergovernmental Panel on Climate Change).

The meetings were held in the Davos Congress Centre that regularly hosts meetings of the World Economic Forum.
Edward and his co-organisers (renowned glaciologists Francisco Navarro, Frank Pattyn and Catherine Ritz) are grateful to the workshop sponsors: the Scientific Committee on Antarctic Research, the International Arctic Science Committee, and the Climate and Cryosphere project of the World Climate Research Programme, especially for facilitating several Early Career Scientists to attend the workshop. Working together with the presenters, it is planned to write a major review/synthesis paper for a leading science journal, summarising the outcomes of the workshop, within the next few months.
