Future Sea Level project marks global-warming challenge

Future Sea Level is a collaborative art project designed to demonstrate how one major consequence of global warming, rising sea levels, would affect important community spaces. The first installation of the project, created by the Sierra Club, Aquarium of the Bay, and San Francisco's Department of Environment, took place at San Francisco's famous Fisherman's Wharf in September.

The idea was sparked after the receding floodwaters from Hurricane Katrina left a visible water line like a bathtub ring throughout New Orleans. Since global warming could raise sea levels by seven meters (23 feet), it seemed natural to create a waterline to depict what might happen to future generations if society fails to address the problem in our time. (This figure reflects what would likely happen if half the Greenland ice sheet and a portion of the Antarctic ice sheet were to melt.) Such a scenario would most likely not play out for 300 years, but the decisions we make now could shape that destiny. By making a future under global warming feel more present, Future Sea Level hopes to motivate ordinary citizens and leaders alike to use practical tools to curb greenhouse emissions.

Look for the next Future Sea Level installation at the Aquarium of the Bay at Pier 39, between Fri., April 14, and Sun., April 22, Earth Day. (April 22 is also the day of the Aquarium's Earth Fest. If you come, be sure to visit the Sierra Club table.) Other Future Sea Level events are in the works here in the Bay Area as well; stay tuned.
