Warning: Many watersheds in US failing ‘stress test’

CNBC: Nearly 1 in 10 of the nation’s watersheds–areas of land that contain runoff from rivers and streams–are stressed to the point to where demand for water exceeds the natural supply. “There is a lot of pressure on our water supply, especially In the western part of the country,” said Kristen Averyt, associate director for science at the Cooperative Institute for Research in Environmental Sciences, and lead author of the report released this month Continue reading

Warming trend a sign of climate change in Clear Lake

Press Democrat: Clear Lake, a haven for bass anglers and jetskiers at the foot of a dormant volcano in Lake County, is also a sentinel for climate change in California. Satellite measurements of the shallow, 68-square-mile lake’s surface water temperature show a pronounced warming since 1992, matching the trend at five other lakes in California and Nevada, including Lake Tahoe. The lakes’ warming is “primarily due to climate change,” said Geoffrey Schladow, director of the Tahoe Environmental Research Center…. Continue reading

What’s causing oil sheens near Deepwater Horizon spill site?

LiveScience: Recurrent sheens of oil in the Gulf of Mexico near the site of 2010′s Deepwater Horizon oil spill have baffled researchers and led to fears that oil may once again be spewing from the seafloor well. But a study published this week in the journal Environmental Science and Technology shows that there is no new leak: The oil is coming from isolated tanks and pockets within the wreckage of the sunken rig, according to a statement from the National Science Foundation (NSF), which funded the research….

Invasive species: ‘away-field advantage’ weaker than ecologists thought

ScienceDaily: For decades, ecologists have assumed the worst invasive species — such as brown tree snakes and kudzu — have an “away-field advantage.” They succeed because they do better in their new territories than they do at home. A new study led by the Smithsonian Environmental Research Center reveals that this fundamental assumption is not nearly as common as people might think. The away-field advantage hypothesis hinges on this idea: Successful invaders do better in a new place because the environment… Continue reading
