250,000 Katrina evacuees seen as "climate refugees"

Some 250,000 evacuees from last year's Hurricane Katrina on the Gulf Coast may never return permanently and should be considered "climate refugees," whose ranks around the world could grow until global warming is mitigated, an environmental expert said.

The number of "climate refugees" will grow unless the world cuts the amount of greenhouse gases it releases, said Lester Brown, president of Earth Policy Institute in Washington D.C.
