The field of global warming skeptics is thinning as rapidly as Greenland’s glaciers, but it hasn’t stopped them from rallying for a counterattack every now and then.

"This is not a drill! It’s happening! Everybody get up!" was the shouted alarm that awoke Splash movie star Daryl Hannah, scores of farmers and other supporters around 5 a.m., June 13, as the state’s boot heel stomped America’s largest urban farm. Three hundred-plus LAPD and L.A. County sheriffs raided the 14-acre South Central Farm, to evict 350 mostly Latino and African-American poor families who’d grown food at a community garden there since 1992, following the Los Angeles riots.
President George W. Bush has dubbed Hawaii’s Northwestern Islands a National Monument, a move that creates the planet’s largest marine reserve. At 139,000 square miles, the ecosystem is nearly as large as California and is home to sharks, whales, coral reefs and endangered Hawaiian monk seals, as well as a host of other marine life.
