Eve Mosher is an American environmental artist living and working in New York City. She is best known for her public art installation HighWaterLine, which premiered in New York City in 2007. Her predictions about where waters would rise due to climate change were validated by flood levels during Hurricane Sandy in 2012. Other locations for installations of HighWaterLine include Miami, Florida, where it was created with the help of volunteers (2013) and Philadelphia, Pennsylvania (2014). Installations have been discussed for Dublin, Ireland, and London, England. Early works Eve Mosher initially worked as a studio artist, creating abstract interpretations of the natural and built environments through drawings, sculptures, and installations. Then, in 2006, she felt a need to do something in response to climate change and began to brainstorm ideas. She was an Exhibiting Artist at Eyebeam in 2008 and 2009. HighWaterLine New York City, New York In 2007 artist Eve S. Mosher created a public art project in Brooklyn and Manhattan that brought the topic of climate change literally to the doorsteps of the city's residents. Scientists had predicted that water levels in New York, in the event of a "hundred year flood", could rise ten feet above sea level. But with sea levels rising along the East Coast — a natural phenomenon accelerated by climate change — they now projected that what was once considered a 100-year flood could soon happen as often as every 3 to 20 years. Eve Mosher used topographic maps, satellite images, and data from NASA's Goddard Institute for Space Studies at Columbia University, to predict the locations likely to be subject to flooding. Then Mosher walked 70 miles of New York coastline, pushing a "Heavy Hitter" (a baseball field line machine) to draw a 4" blue chalk line on the ground, marking the predicted water levels. In areas where she was unable to draw a line, she marked the high water boundary with illuminated beacons. The project was completed over a period of six months. Mosher's HighWaterLine went past low-income housing developments, luxury apartment buildings, power stations, nursing homes, and hospitals. One observer wrote later, "it was beyond moving to see an artist simplify complex data that typically might seem too abstract to relate to." Along the way, people came up to her to ask what she was doing, and Mosher talked with them. A significant goal of the project was to engage
