SUMMARY:Ice and High Water - the Contribution of Polar Ice to Present and 
 Future Sea-Level Rise - Prof. David Vaughan (British Antarctic Survey)

DESCRIPTION:The future security and prosperity of Europe's coastal cities 
 and survival of many unique coastal habitats requires scientists to delive
 r reliable sea-level projections which will form the basis of adaptation\,
  management and protection planning for vulnerable coastal regions.  Most 
 of the contributions to sea-level rise can now be predicted with some conf
 idence\; the greatest remaining uncertainty lies in the contribution ice-l
 oss from the polar ice sheets resting on Antarctica and Greenland.  Indeed
 \, the IPCC's 2007 assessment contained a limited confidence in statements
  concerning the future contribution of ice sheet to sea-level rise.  In th
 is talk\, I will highlight the recent progress that has allowed us to meas
 ure current ice-loss from Arctic glaciers and Greenland\, and the key vuln
 erabilities that may lead to substantial loss in future\, to irreversible 
 ice- and eventually lead sheet retreat.  I explain the relationship betwee
 n global sea-level rise\, and what we actually see along particular sector
 s of the coasts\, and how sea-level rise will impact the frequency of dama
 ging flood events on timescales ranging from years to centuries.  I will t
 alk about current work being undertaken at British Antarctic Survey to add
 ress these and other significant science questions\, and the opportunities
  for UK scientists to develop science in Antarctica.
