"Climate scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered that particulate pollution in the late 20th century created a "warming hole" over the eastern United States-that is, a cold patch where the effects of global warming were temporarily obscured."

"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.

"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."

"In the depths of the ocean and on shore, science is only beginning to measure the long-term impact of the worst oil spill in U.S. history."

"The Chesapeake Bay Foundation and other environmental groups have urged a Pennsylvania federal judge to dismiss a lawsuit challenging the federal government's plan for reducing pollution fouling the estuary."

"LOUISVILLE, Ky. -- Black dust from the giant coal ash heap across the street from Kathy Little's Louisville home swirls in the wind, coating her windows, her car, and blows indoors to settle on the furniture. The ash blanketing Little's property is a byproduct of a nearby coal-burning power plant. Since it's full of fine particles of arsenic, chromium and other metals, the U.S. Environmental Protection Agency is considering classifying the ash as a hazardous material."

"WASHINGTON -- Oil and gas companies will have to capture toxic and climate-altering gases from wells, storage sites and pipelines under new air quality standards issued on Wednesday by the Environmental Protection Agency. The rule is the first federal effort to address serious air pollution associated with the natural gas drilling process known as hydraulic fracturing, or fracking, which releases toxic and cancer-causing chemicals like benzene and hexane, as well as methane, a powerful greenhouse gas."

Fishermen -- and LSU Prof. Jim Cowan -- say that eyeless shrimp and fish with lesions are becoming common in the Gulf of Mexico, with the 2010 BP oil pollution believed to be the likely cause.
