A Greenlandic fishing boat works amongst the ice bergs in the mouth of the Ilulissat 'Ice' Fjord. Greenpeace and an independent NASA-funded scientist completed measurements of melt lakes on the Greenland Ice Sheet that show its vulnerability to warming temperatures. The measurements are the last scheduled activity as the Greenpeace ship Arctic Sunrise wraps up its two-month expedition to document the impacts of climate change on Greenland's ice sheet and glaciers.
