Check out video featuring a rooftop painting by Molly Dilworth made on the roof of ACORN High School at 561 Grand Avenue, Brooklyn, NY in November 2010.

This piece was one of 24 global large-scale artworks organized by 350.org calling for climate change action before the December 2012 United Nation climate talks in Cancun, Mexico. This project uses infrared-reflective roof coating to help ameliorate the heat-island effect and to mark a physical presence in digital space.

The image represents the NYC harbor after a 7-meter rise in sea levels. The blue is the water as it is today, the brown is the land that would be left after such a rise and the white is the new water line.
