Sculptures highlight global warming

A pair of metal sculptures is seen on an iceberg near the town of Uummannaq in western Greenland March 19, 2010. Ap Verheggen, a 45-year-old artist from The Hague, said he had built the swirling metal sculptures, which represent a dog sled, to highlight the impact of a warmer climate on the Inuit people, who struggle to move around on thinning ice.
