RedOrbit: As climate scientists continue to sound warnings about how the impending sea level rise will impact coastal cities, a group of Australian researchers has found that shorebirds could be feeling squeezed even more than humans. According to the research teams report in the Proceedings of The Royal Society B (RSPB), a 23 to 40 percent loss of shorebirds main feeding grounds could lead to a 70 percent decline in their population. Each year, millions of shorebirds stop at coastal wetlands to rest...
