Climate change is a downright abstract concept to get your head around. The science is complicated, the effects are broad yet nuanced, and not everyone will be impacted in the same way. So, what is an impactful way to represent the dangers posed by climate change that everyone can understand?
One project is raising eyebrows by literally drawing a line through the community. The HighWaterLine is a visual representation of projected, future sea-level rise as a result of global warming and more frequent and stronger storms and storm surges. Using various media, such as a blue chalk outline, or even a human chain, a revised flood zone based on current climate data is delineated within an urban/suburban area, bringing the reality of a warming planet home to local residents.
The HighWaterLine is the brainchild of NYC-based artist, Eve Mosher, who initially based the project on climate change data contained within a NASA Goddard Institute for Space Studies report issued in 2001. Having read the report and witnessing a watered-down response from public officials, Ms. Mosher was determined to take matters into her own hands.
After nearly eight months of research and planning, Ms. Mosher installed the first iteration of The HighWaterLine in August 2007 along 70 miles of coastline in Brooklyn and Lower Manhattan, demarcating the 10 foot about sea level rise with a 4-inch wide blue chalk line.
To encourage others to replicate the project in their own communities, Ms. Mosher devised a HighWaterLine “Action Guide,” in essence a simplified toolkit of knowledge bites and best practices, to ensure easy replication of the project elsewhere.
