This US artist plants a 'ghost forest' in New York

In the centre of New York City's spring greenery, artist Maya Lin has installed the barren, brown trunks of 49 dead Atlantic White Cedar trees in a Manhattan park as a "Ghost Forest" to warn of the danger of climate change and the threat of rising sea water.

"This is a grove of Atlantic Cedars... victims of saltwater inundation from rising seas due to climate change," said Lin, designer of the Vietnam Veterans Memorial in Washington, DC.
