For decades, the residents of Libby, Montana have lived a double life.
On the outside, the town of 3,000 people along the Kootenai River is a picture postcard of why western Montana is one of the most gorgeous places in the country.
Unseen, though, is how asbestos pollution from a former W.R. Grace & Co. mine has sickened more than 1,300 residents with a deadly lung disease, killing many of them and turning Libby into the deadliest Superfund site in the nation's history.
At least one billion becquerels a day of radiation continue to leak from Japan’s Fukushima nuclear plant after the March earthquake and tsunami.
Experts say that the total amount of radiation leaked will exceed amounts released from Chernobyl, making Fukushima the worst nuclear disaster in history.
The Arkansas Oil and Gas Commission has banned fracking disposal wells for unconventional gas drilling wastes due to earthquakes. The Commission voted unanimously to ban them, and the decision requires the immediate closure of one disposal well and prohibits the construction of new wells within a 1,150 square mile radius.
Arkansas residents insisted that there was a correlation between the increase in earthquake activity in the state and wastewater disposal wells. Imagine being on your way out one afternoon, opening your garage door, and experiencing an earthquake that you knew was being caused by gas drills.
Arctic sea ice melted this summer to the second lowest level since record-keeping began more than 50 years ago, scientists reported Thursday, mostly blaming global warming.
"This is not a random event," said oceanographer James Overland of the U.S. National Oceanic and Atmospheric Administration. "It's a long-term change in Arctic climate."
Coral reefs are on course to become the first ecosystem that human activity will eliminate entirely from the Earth, a leading United Nations scientist claims. He says this event will occur before the end of the present century, which means that there are children already born who will live to see a world without coral.
The claim is made in a book published tomorrow, which says coral reef ecosystems are very likely to disappear this century in what would be "a new first for mankind – the 'extinction' of an entire ecosystem". Its author, Professor Peter Sale, studied the Great Barrier Reef for 20 years at the University of Sydney. He currently leads a team at the United Nations University Institute for Water, Environment and Health.
Switching from burning coal to natural gas won't have an appreciable effect on global warming, at least not in the next few decades, a study suggests.
In fact, cutting worldwide coal burning by half and using natural gas instead would increase global temperatures over the next four decades by about one-tenth of a degree Fahrenheit, according to Tom Wigley, a senior research associate at the National Center for Atmospheric Research.
Japan has been slow to admit the scale of the meltdown. But now the truth is coming out.
This nation has recovered from worse natural – and manmade – catastrophes. But it is the triple meltdown and its aftermath at the Fukushima nuclear power plant 40km down the coast from Soma that has elevated Japan into unknown, and unknowable, terrain. Across the northeast, millions of people are living with its consequences and searching for a consensus on a safe radiation level that does not exist. Experts give bewilderingly different assessments of its dangers.
