The last two decades have seen various unusual chan ges in the ice sheets, with the breakup of massive ice shelves from the Ant arctic Peninsula and several major surface melt events in Greenland perhaps being most iconic. But how reflective are short-term extreme events of lon ger-term change and what is role of external forcing (e.g. climate change) versus internal variability (e.g. short-term variations in atmospheric and oceanic circulation and ice dynamics)?
T his 1.5-day workshop will explore the degree to which short-term fluctuatio ns and extreme events in the ice sheets (both Greenland and Antarctica) in the last two decades reflect their longer-term evolution and response to on going climate change. Considerable recent progress, summarised in the Inter governmental Panel on Climate Change’s AR6 WG1 August 2021 report, has been made on current state-of-the-science understanding of ice-sheet change. Ho wever, despite amplified global warming that has recently occurred over Gre enland and around the Antarctic Peninsula, significant uncertainties remain concerning mass changes of the ice sheets during the rest of this century. Two major open questions relate to dynamic mass losses and potential non-l inear feedbacks from Antarctica but also melt- and dynamic- related feedbac ks from Greenland.
We will consider the interplay of forcings from the ocean and atmosphere and their interactions with ice-sheet changes on timescales of days to centuries. Information on t he historical mass changes of both Greenland and Antarctica before the mode rn satellite era is distinctly limited but may be improved through the rece nt availability of new datasets, whilst the modelling community has embrace d advancing computer capability and novel simulation approaches. We will di scuss recent innovations and recommendations for the next 5-10 years that a re required in observations, process studies and modelling efforts to make further major breakthroughs in understanding how ice sheets change and the resulting local to global impacts: for example in sea-level rise and extrem e weather. Fully realising advances in climate and ocean models, as well as ice-sheet modelling, is an essential part of improving the understanding o f ice-sheet changes and sensitivity. This workshop will consist of a mix of invited keynote talks and panel/discussion sessions that will address thes e crucial issues from a multi-disciplinary perspective.
We currently plan this to be an in-person event (COVI D restrictions permitting).
Plea se contact Edward Hanna (This email address is being protected from spambots. You ne ed JavaScript enabled to view it.), putting “ISMASS Iceland workshop” in the subject header of your email, if y ou are interested in participating.
We envisage that at least 50 places will be available, possibly more depending on interest, and places will be allocated on a ‘first come, first served’ basis. There is no regis tration charge but participants planning to attend the Cryosphere 20 22 symposium during the same week (linked above, and which has a very compl ementary programme) will need to register/pay for that.
