'Art can play a valuable role': climate change installations appear in New York

Solar-powered highway signs have been placed in the city's five boroughs as part of the Climate Signals installation

The existential threat of climate change is being spelled out to New Yorkers via a selection of flashing highway signs that have been placed around the city.

The 10 large solar-powered signs have been placed in locations in each of New York's five boroughs, including areas deemed particularly vulnerable to the sea level rise and powerful storms associated with climate change, including the Rockaways in Queens and the west side of Manhattan.
