John Christy, the Alabama state climatologist who authored the study, said the amount of snow in the mountains has not...
Climate change: Sea rise could kill vital marshes

San Francisco Chronicle: The critical tidal marshes of San Francisco Bay - habitat for tens of thousands of birds and other animals - will virtually disappear within a century if the sea rises as high as some scientists predict it will as a result of global warming.
The sea would inundate the coastline and eliminate 93 percent of the bay's tidal wetlands if carbon emissions continue unchecked and the ocean rises 5.4 feet, as predicted by scientists under a worst-case scenario, according to a new study by PRBO Conservation...
