Estuarial cities at risk from sea level rises of 0.9 to 1.6 metres by 2100

According to a report issued by the Norwegian based Artic Monitoring and Assessment Programme:

  • The past six years (2005–2010) have been the warmest period ever recorded in the Arctic.  Higher surface air temperatures are driving changes in the cryosphere.  There is evidence that two components of the Arctic cryosphere – snow and sea ice – are interacting with the climate system to accelerate warming.
  • The Arctic Ocean is projected to become nearly ice-free in summer within this century, likely within the next thirty to forty years.
  • Arctic glaciers, ice caps and the Greenland Ice Sheet contributed over 40% of the global sea level rise of around 3 mm per year observed between 2003 and 2008. In the future, global sea level is projected to rise by 0.9–1.6 m by 2100 and Arctic ice loss will make a substantial contribution to this.
