Most streams in the Chesapeake Bay region are warming, an air-driven increase that could have significant impacts on the ailing estuary, a new study says.

Their research was published in the journal Climate Change. Even small increases in water temperature can affect water quality and the animals that rely on the bay's streams, said Karen Rice, USGS research hydrologist and lead author of the study.  Warming...
