"Polar bears are capable of swimming vast distances, a potential survival skill needed in an Arctic environment where summer sea ice is vanishing, a study led by the U.S. Geological Survey showed on Tuesday."
"Some of the main proposals in a draft text for negotiation at a U.N. sustainable development conference next month are being watered down at informal talks in New York, observers said on Tuesday, heightening fears the summit will fail to deliver."
"The cause célèbre of plastic litter in the ocean is the Texas-sized, swirling island of plastic debris thousands of miles off the coast of California in the Pacific Ocean. But researchers from the Universities of Washington and Delaware and the Sea Education Association in Woods Hole, Mass., say the story is much bigger, and scarier, than that."
"A federal judge has ruled that NCR Corp. is responsible for paying for environmental damage to the Fox River in northeastern Wisconsin -- a decision that is expected to jump-start stalled cleanup work on the massive pollution project."
"CLINTON, Ill. -- Fly over Clinton and the 266-acre landfill south of town doesn't look much different than 44 other landfills in Illinois.
But beneath its surface of inoffensive trash, the kind you put at the curb each week, are 4 trillion gallons of water used every day for public use, industry and irrigation in 15 Central Illinois counties.
And if ever the two shall meet, there could be trouble for the 750,000 people who rely on the Mahomet Aquifer, especially if Area Disposal's landfill starts accepting PCBs, a certain type of hazardous waste.
"Pacific reef shark populations have plummeted by 90 percent or more over the past several decades, according to a new study by a team of American and Canadian researchers, and much of this decline stems from human fishing pressure.
Quantifying the decline for the first time, the analysis, published online Friday in the journal Conservation Biology, shows that shark populations fare worse the closer they are to people — even if the nearest population is an atoll with fewer than 100 residents.
"They say oil and water don't mix, but when it comes to oil and gas drilling, water and oil are practically joined at the hip. It takes millions of gallons of water to drill a well. Water is the 'hydraulic' in the hydraulic fracturing process used to release oil and gas deposits. Disposing of wastewater is a costly challenge for drillers. And, at every step along the way, preventing groundwater contamination is the paramount concern for inspectors and regulators."
"The Sierra Club will try to use a 40-year-old legal settlement to scuttle plans by Dominion Resources Inc to convert a liquefied natural gas terminal in Maryland into a major export hub."
"Some worry that a water-diversion deal, sending farm irrigation water to sprawling San Diego, will spell doom for the Salton Sea – and exposure to toxins for humans and wildlife. Others say protections are in place to ensure that can't happen."
