Arctic Ozone Loss 'Unprecedented,' Scientists Say

Unusual winter weather in the atmosphere high above the Earth's surface caused an "unprecedented" loss of protective ozone over the Arctic this year, scientists say.

The ozone layer in the stratosphere, located about 15 to 35 kilometres above the Earth's surface, protects the Earth from the sun's ultraviolet rays and harmful effects such as skin cancer. While an ozone hole has formed in the stratosphere over the Antarctic each spring since the mid 1980s, a paper published in Nature on Sunday marks the first time scientists have reported a comparable loss over the Arctic.

AP: BP Oil Not Degrading on Gulf Floor, Study Says

BIRMINGHAM, Ala. (AP) — Tar balls washed onto Gulf of Mexico beaches by Tropical Storm Lee earlier this month show that oil left over from last year's BP spill isn't breaking down as quickly as some scientists thought it would, university researchers said Tuesday.

Auburn University experts who studied tar samples at the request of coastal leaders said the latest wave of gooey orbs and chunks appeared relatively fresh, smelled strongly and were hardly changed chemically from the weathered oil that collected on Gulf beaches during the spill.

The study concluded that mats of oil — not weathered tar, which is harder and contains fewer hydrocarbons — are still submerged on the seabed and could pose a long-term risk to coastal ecosystems.

Controversial Study Shows Higher Cancer Risk in 9/11 Firefighters

(CBS) The 9/11 terrorist attacks in New York City killed almost 3,000 people, but what about New Yorkers who were in the area at the time but survived? New studies show they face heightened risk for asthma, post-traumatic stress disorder, and cancer - but not all health experts agree the attacks are to blame for survivors' health problems.

For one study - published in the September 1 issue of The Lancet - Mount Sinai researchers evaluated more than 27,000 police officers, firefighters, construction workers, and office workers who were in or around ground zero over the nine years following 9/11. The researchers found more than one in five responders had multiple physical or mental health illnesses.

Deepwater Trouble on the Horizon: Oil Discovered Floating Near Source of Gulf of Mexico Spill (Video & Photos)

MOBILE, Alabama -- Oil is once again fouling the Gulf of Mexico around the Deepwater Horizon well, which was capped a little over a year ago.

Tuesday afternoon, hundreds of small, circular patches of oily sheen dotted the surface within a mile of the wellhead. With just a bare sheen present over about a quarter-mile, the scene was a far cry from the massive slick that covered the Gulf last summer.

Floating in a boat near the well site, Press-Register reporters watched blobs of oil rise to the surface and bloom into iridescent yellow patches. Those patches quickly expanded into rainbow sheens 4 to 5 feet across.

Each expanding bloom released a pronounced and pungent petroleum smell. Most of the oil was located in a patch about 50 yards wide and a quarter of a mile long.

As Heat Soars, New Yorkers Warned to Stay Out of Rivers

Sun, 2011-07-24 00:34 — Kathy Gilbeaux

msnbc.com - July 22, 2011

A warning by the Hudson River near West 90th Street on Thursday. Millions of gallons of untreated waste spilled into the river - Monika Graff for The New York Times

New Yorkers have been warned to stay out of the Hudson and Harlem Rivers on one of the hottest weekends of the year after millions of gallons of untreated sewage discharged from Manhattan into the waterways because of a four-alarm fire that shut down one of the city’s largest sewage treatment plants.

The city's drinking water has not been impacted, officials said, but people have been cautioned not to swim or kayak on the waterways through at least Monday.

The New York City health department also declared large parts of the East River and the Kill Van Kull unfit for swimming through the weekend.

Local authorities did not expect any beaches in the area to be closed because of the spill.

EPA Fracking Study To Focus On 5 States, But Not Wyoming

Mon, 2011-06-27 10:06 — Kathy Gilbeaux

The Huffington Post - June 26, 2011

by ProPublica's Abrahm Lustgarten

The Environmental Protection Agency will focus its national study of hydraulic fracturing on seven areas in five states, but will exclude the two Wyoming gas fields where agency researchers have already collected some of the most in-depth data on drilling's environmental impacts.

The study – which was announced last March, without specifics on research sites – will investigate alleged water contamination from drilling in five areas in Texas, Colorado, North Dakota and Pennsylvania. It also will encompass cradle-to-grave research projects in Pennsylvania and Louisiana, where the agency will track drilling's effects on water quality from before the drill bit hits the ground to after hydraulic fracturing has been performed.
