Alliance was the first international organization to commission high profile, large-scale works of art on the subject of global warming. Carroll elected to appropriate the form of the neon sign, emphasizing the concreteness of language while assuring that the commission retained its identity as a work of art. As material, neon recommended itself for its historical references to industrial signage, for its sheer visibility— important for this first Precipice work, so that it might garner maximum attention, and because the latest technology would make it carbon neutral. For indestructible language, Carroll secured a site at the defunct American Can Company along the Pulaski Skyway, a landmarked roadway in New Jersey that heads to and from the Holland Tunnel into Manhattan. The piece stretched across five buildings parallel to the skyway, with the final words rounding the corner of the north side of the fifth building so that they were visible as a solitary phrase when heading toward New York City. The area surrounding the site is an industrial wasteland. The scale of indestructible language necessitated collaboration with and permissions from numerous state agencies, from Governor Jon Corzine’s office to Jersey City’s Mayor Jerramiah Healy’s office to the traffic division for the state. The sign was visible for a period of six months from distances of up to four miles, including to airplanes flying into Newark International Airport, to commuter trains and rail lines running along the eastern seaboard, and to automobile traffic on the Pulaski Skyway, the New Jersey Turnpike, and other roadways. IT IS GREEN THINKS NATURE EVEN IN THE DARK. The sentence Carroll chose for the piece, from the more than 200 she generated in Excel spreadsheets, issued from the basic premise taken from the media that global warming is a moral issue when actually a scientific fact.
