"New research shows that killer whales are inhaling bacteria, fungi and viruses once believed to be found only on land. Some of the pathogens are highly virulent. And some are even antibiotic-resistant."

"To the untrained eye, a weed is just a weed, and few of us can tell a thistle from a teasel. But for Paul Heiple and his team of Weed Warriors, knowing the difference is essential to their work routing out invasive plants that threaten the native species at Edgewood Park, a 500-acre natural preserve that overlooks California’s Silicon Valley."

"Federal Fish and Wildlife Service officials say that a drought-induced bird die-off in the Lower Klamath National Wildlife Refuge along the California-Oregon border has ended. But they warn that unless proposals to reconfigure water distribution along the Klamath River are enacted, the problem could recur."

"Sea level rise from global warming is well on the way to doubling the risk of coastal floods 4 feet or more over high tide by 2030 at locations nationwide. In the lower 48 states, nearly 300 energy facilities stand on land below that level, including natural gas infrastructure, electric power plants, and oil and gas refineries. Many more facilities are at risk at higher levels, where flooding will become progressively more likely with time as the sea continues to rise. These results come from a Climate Central combined analysis of datasets from NOAA, USGS and FEMA."

"Scientists may hesitate to link some of the weather extremes of recent years to global warming -- but the public, it seems, is already there."

"BOARDMAN, Ore. -- A new link in the world's future energy supply could soon be built here on the Columbia River, and it would have nothing to do with the vast acres of wind turbines or the mammoth hydroelectric dams that give this region's power sources one of the cleanest carbon footprints in the nation."

"The company planning the disputed Keystone XL oil pipeline has proposed a new route through Nebraska that avoids the state's environmentally sensitive Sandhills region."
