Greenpeace warns of beach loss

Standing 24 feet above the high-tide line, Greenpeace volunteers and sunbathers at Smathers Beach Wednesday marked the loss the beach could face if global warming continues at its current pace.

"The Keys are going to go under," said Kitsy McMullen, Greenpeace climate impacts campaigner, as the group opened its Take Back the Earth Tour in Key West.

Rising sea levels threaten shorelines and coral reefs everywhere, and Greenpeace activists say President George Bush and Vice President Dick Cheney's energy plan is likely to speed up the effects.
