Greenland ice sheet
Published (reviewed and quality assured)
Justification for indicator selection
The fate of the Greenland ice sheet highlights potentially major consequences of climate change as it is directly linked to global sea-level rise. The speed of ice loss, known as the ice sheet ‘mass balance’, is the most important indicator of ice sheet change. An increased rate of mass loss results in a faster rise in sea level. In addition, melt water from Greenland reduces the salinity of the surrounding ocean. An upper layer of fresher water may reduce the formation of dense deep water, one of the mechanisms driving global ocean circulation.

Policy context and targets
In April 2013 the European Commission presented the EU Adaptation Strategy Package (http://ec.europa.eu/clima/policies/adaptation/what/documentation_en.htm). This package consists of the EU Strategy on adaptation to climate change /* COM/2013/0216 final */ and a number of supporting documents. One of the objectives of the EU Adaptation Strategy is Better informed decision-making, which should occur through Bridging the knowledge gap and Further developing Climate-ADAPT as the ‘one-stop shop’ for adaptation information in Europe. Further objectives include Promoting action by Member States and Climate-proofing EU action: promoting adaptation in key vulnerable sectors. Many EU Member States have already taken action, such as by adopting national adaptation strategies, and several have also prepared action plans on climate change adaptation.
The European Commission and the European Environment Agency have developed the European Climate Adaptation Platform (Climate-ADAPT, http://climate-adapt.eea.europa.eu/) to share knowledge on observed and projected climate change and its impacts on environmental and social systems and on human health; on relevant research; on EU, national and subnational adaptation strategies and plans; and on adaptation case studies.
No targets have been specified.

Adaptation means anticipating the adverse effects of climate change and taking appropriate action to prevent or minimise the damage they can cause, or taking advantage of opportunities that may arise. It has been shown that well planned, early adaptation action saves money and lives later. This webportal provides information on all adaptation activities of the European Commission.
EU Adaptation Strategy Package
In April 2013 the European Commission adopted an EU strategy on adaptation to climate change which has been welcomed by the EU Member States. The strategy aims to make Europe more climate-resilient. By taking a coherent approach and providing for improved coordination, it will enhance the preparedness and capacity of all governance levels to respond to the impacts of climate change.
Methodology for indicator calculation
Estimates are based on the mass budget method based on a combination of the output from regional climate models and various satellite-borne datasets (altimetry and gravimetry data).
The graphs show the data as delivered by the authors of the referenced publications; a linear trend line was added.
Methodology for gap filling

Data sets uncertainty
Data on the cryosphere vary significantly with regard to availability and quality. Snow and ice cover have been monitored globally since satellite measurements started in the 1970s. Improvements in technology allow for more detailed observations and higher resolution. Direct historical area-wide data on the Greenland ice sheet tracks about 20 years, but reconstructions give a 200 000 year perspective.
Further information on uncertainties is provided in Section 1.7 of the EEA report on Climate change, impacts, and vulnerability in Europe 2012 (http://www.eea.europa.eu/publications/climate-impacts-and-vulnerability-2012/)
