Rising Sea Levels May Cause Saltmarsh Sparrow And Other American Birds To Be Extinct
Bird population is declining in Connecticut, which officials fear could lead to extinction. The Saltmarsh Sparrow's subscpecies, Dusky Seaside Sparrow, was officially declared extinct in 1990 after the last known specimen died in 1987. The Saltmarsh Sparrow could be facing the same disaster.
Global warming shown in data from 19th century expedition
The HMS Challenger set sail during 1872 on the world's first scientific mission to explore life beneath the surface of the oceans. As part of their research, the crew of Challenger lowered thermometers hundreds of feet beneath the ocean's surface. Examination of data from that four-year-long scientific mission lends evidence supporting a rise in global sea temperatures since that time.
