Ozone loss over the Arctic this year was so severe that for the first time it could be called an "ozone hole" like the Antarctic one, scientists report. About 20km (13 miles) above the ground, 80% of the ozone was lost, they say.
The cause was an unusually long spell of cold weather at altitude. In cold conditions, the chlorine chemicals that destroy ozone are at their most active.

The Trouble With Health Problems Near Gas Fracking
Nobody has systemically tracked how many health complaints there are, whether the complaints are similar, whether they can be tied to any specific chemical exposure or any environmental cause. It makes it very difficult beyond an anecdotal answer to get a handle on how widespread a problem this might be."
Part of the problem, writes Lustgarten, is that "the drilling companies have complicated efforts to gather pollution data and to understand the root of health complaints."
Is it Safe to Store Fracking Fluid Underground?
It’s not enough to have to worry about oil and gas companies building more and more shale gas wells in places like Pennsylvania, Ohio and New York. We also have to worry about them drilling wells 8,000 feet deep to store the leftover fracking fluid, like they do in Cambridge, OH, with a company called Devco.
Next door, in Pennsylvania, industry trieddumping the wastewater leftover from fracking into streams. When environmentalists questioned this disposal method, industry responded with claims that the streams dilute the chemicals enough to make such a method safe.
EPA to regulate natural gas fracking operations' gas emissions
Much of the focus on hydraulic fracturing (or fracking) for natural gas pertains to potential effects of this technology on water resources, as I discussed in an earlier blog entry.
Yet, the process of fracking, oil and gas production, natural gas processing, natural gas transmission, and natural gas distribution also releases a variety of potentially harmful gases into the atmosphere.
U.S. secretly asked Japan to help dump nuclear reactors
The United States secretly sought Japan's support in 1972 to enable it to dump decommissioned nuclear reactors into the world's oceans under the London Convention, an international treaty being drawn up at the time.
Countries working on the wording of the pact wanted to specifically prohibit the dumping of radioactive waste at sea.
But Washington wanted to incorporate an exceptional clause in the case of decommissioned nuclear reactors.
West Hollywood votes to ban fur sales
This proudly liberal city has been out front on gay rights, protection of animals and limits on handguns, and even declared an upcoming "Go-Go Dancer Appreciation Day."
But its latest move has the fur flying in a catfight between animal-rights activists and fashionistas. A unanimous City Council vote last week to ban the sale of fur apparel has outraged the fashion industry, one of the primary businesses this tiny city, wedged between Los Angeles and Beverly Hills, has worked hard to attract.
Is natural gas 'fracking' responsible for the recent earthquake swarms in strange locations?
The natural gas industry and its advocates claim that hydraulic fracturing, the modern technique for extracting natural gas, also known as "fracking," is beneficial to the interests of American energy independence.
However, a simple report recently issued by KARK 4 News in Little Rock, Ark., suggests that fracking operations, which involve pumping large amounts of water and chemicals deep underground, may be responsible for triggering the mysterious earthquakes that have been striking in unusual locations across the nation in recent months.
