New York City’s coastal location makes it particularly vulnerable to rising sea levels that will result from unabated warming. A ten-foot change could result from significant melting of the Antarctic and Greenland ice shelves over the course of this century. Such a rise would greatly reconfigure the map of our city, sinking much of lower Manhattan beneath the water.

The Sea Of People project combines the dynamics of a mass rally with the expressive power of an interactive artistic installation. Following a 12 Noon Rally in Battery Park on Saturday, April 14, 2007, thousands of participants, dressed in blue, will stretch north in two columns along the projected eastern and western 10-foot waterlines that may one day redefine lower Manhattan under the ten-foot sea level rise scenario.

I signed up and, hopefully, will have time to whip up something special in recycled blue. How about you, need some protest clothes? Why not reuse? Just search "blue" and let the eBaybes™ guide you, but first don't forget to sign up. They need about 5,000 participants and 200 volunteers.
