The possibly failed salt cavern may be closer to the outer wall of the Napoleonville Dome than Texas Brine officials believed.• DNR defended the timing of its disclosures about the history surrounding the salt cavern as matching the emerging facts of the incidents in Bayou Corne.• Sonny Cranch, Texas Brine spokesman, said company officials have been as surprised as anyone about a possible collapse of their salt cavern.• DNR officials allowed Texas Brine to deposit naturally-occurring radioactive material arising from drilling into two company salt caverns, including the one that may have breached in the Bayou Corne area. As of Wednesday, state environmental officials had not tested the sinkhole for radioactivity."

Friday evening, the day the sinkhole developed and released a foul diesel odor was the first time DNR officials made public information indicating that the cavern may have failed and caused the sinkhole, a “slurry area.” Tuesday night, DNR and Texas Brine officials explained that the cavern appeared closer to Napoleonville Dome’s edge than thought when the cavern was issued a state permit 1982, and that the cavern wall might have been breached. That failure could allow a connection between the cavern’s brine contents and sediments around the dome.

Ball said DNR officials focused on locating a source of the natural gas large enough to send gas bubbling up in the bayous and they focused on area natural gas pipelines and two salt caverns known to be storing natural gas under pressure.

A giant wall of dust rolled through the Phoenix area on Thursday for the third time since early July — turning the sky brown, creating dangerous driving conditions and delaying some airline flights. The dust storm, also known as a haboob in Arabic and around Arizona, swept through Pinal County and headed northeast, reaching Phoenix at about 6 p.m. Some incoming and departing flights at Phoenix Sky Harbor International Airport were temporarily delayed because of the storm, according to airport officials who couldn’t immediately provide exact numbers. Take-offs and landing began again at about 6:50 p.m. National Weather Service meteorologists said a powerful thunderstorm packing winds of up to 60 mph hit Pinal County and pushed the dust storm toward Arizona’s most populous county. There were several reports of downed poles and Salt River Project officials said 3,500 of its customers were without electricity, mostly in the Queen Creek area southeast of Phoenix. There were no immediate reports of any weather-related auto accidents. It was the third major dust storm to hit the Phoenix metro area since last month. A haboob on July 5 brought a mile-high wall of dust that halted airline flights, knocked out power for 10,000 people and covered everything in its path with a thick sheet of dust. Another dust storm hit July 18 reaching heights of 3,000 to 4,000 feet, delaying flights and cutting off power for more than 2,000 people in the Phoenix metro area. Weather officials say haboobs only happen in Arizona, the Sahara desert and parts of the Middle East because of dry conditions and large amounts of sand. –The Chron

Dramatic and unprecedented plumes of methane – a greenhouse gas 20 times more potent than carbon dioxide – have been seen bubbling to the surface of the Arctic Ocean by scientists undertaking an extensive survey of the region.

The scale and volume of the methane release has astonished the head of the Russian research team

never before witnessed the scale and force of the methane being released from beneath the Arctic seabed.

"And what we want do," says John Sauven, who is executive director of Greenpeace UK, "is say that this area, which is currently not national territory, this area of sea ice around the North Pole, should be a 'global commons', collectively owned by humanity under the auspices of the United Nations.

So now Greenpeace, Mr Sauven says, is planning a global campaign to make the North Pole off-limits. Internalionalised. No development. No oil drilling. No territorial claims

It has done so by its own form of protest, by being present (often at considerable personal risk) at the sharp end of all these situations, and making the world aware: it is the idea of "bearing witness", from the Quaker background of some its founders.

New research from Carnegie's Global Ecology department concludes that evaporated water helps cool the earth as a whole, not just the local area of evaporation, demonstrating that evaporation of water from trees and lakes could have a cooling effect on the entire atmosphere

Globally, this cycle of evaporation and condensation moves energy around, but cannot create or destroy energy. So, evaporation cannot directly affect the global balance of energy on our planet.

It is well known that the paving over of urban areas and the clearing of forests can contribute to local warming by decreasing local evaporative cooling, but it was not understood whether this decreased evaporation would also contribute to global warming

Radioactive contamination at the Treasure Island Naval Station, where San Francisco plans to build a high-rise community for 20,000 residents, is more widespread than previously disclosed, according to a new U.S. Navy report and other documents obtained by The Bay Citizen.

The draft report, dated Aug. 6, marks the first time the Navy has fully acknowledged that the island, created from landfill in 1937, was used as a repair and salvage operation for a Pacific fleet exposed to atomic blasts during the Cold War. The report came in response to state regulators, who pressed for details after cleanup workers found radioactive waste in unexpected locations.

Known potential sources of radiation on the island included a nuclear training ship intentionally doused in radiation and even glow-in-the-dark buttons handed out at the 1939-1940 Golden Gate International Exposition held on the island.

To grasp the almost suicidal state of unreality our Government has been driven into by the obsession with global warming, it is necessary to put together the two sides to an overall picture – each vividly highlighted by events of recent days

On one hand there is the utterly lamentable state of the science which underpins it all, illuminated yet again by “Climategate 2.0”,

On the other hand, we see the damage done by the political consequences of this scare, which will directly impinge, in various ways, on all our lives.

A troubling trend has emerged recently: Wildfires are increasing across much of the north, and early research suggests that extensive burning could lead to a more rapid thaw of permafrost.

Thawing has been most notable at the southern margins. Across huge areas, including much of central Alaska, permafrost is hovering just below the freezing point, and is expected to start thawing in earnest as soon as the 2020s.

In a bombshell revelation that’s going viral, BP has admitted to conducting a study to “track oil from seabed to surface” in the Macondo Prospect. Sounds to me like they’ve found a leak. Not so fast. A leak would suggest BP is to blame (perish the thought), but a “natural seep” would imply an act of God, conveniently out of the hands of mere mortals. Here’s how Sabrina Canfield covered the BP disclosure for Courthouse News Service on Nov. 21:

nd a leak.

In an emailed statement late Friday, a representative from BP verified that several vessels are in the vicinity of the Macondo well: “There are several vessels there participating in a study of natural oil seeps. This study has been ongoing for the past month or so. Data continues being collected and we provided an update on the natural oil seeps at the SETAC [Society of Environmental Toxicology and Chemistry] conference in Boston this week. … The study is documenting the specific locations of these seeps and is seeking to track oil flow from seabed to surface,” BP wrote. If there are seeps in the area, they are not natural. I can assure you of that. BP was required to conduct a seafloor survey prior to applying for a permit to drill. If these seeps were not discovered during the survey – which they apparently weren’t – they must be related to the disaster and the heavy-handed methods used to attempt to seal the well.

In a new analysis of the past six decades of global temperatures, which will be published Monday, my colleagues and I have revealed a stunning increase in the frequency of extremely hot summers, with deeply troubling ramifications for not only our future but also for our present.

The deadly European heat wave of 2003, the fiery Russian heat wave of 2010 and catastrophic droughts in Texas and Oklahoma last year can each be attributed to climate change. And once the data are gathered in a few weeks’ time, it’s likely that the same will be true for the extremely hot summer the United States is suffering through right now.

Our new peer-reviewed study, published by the National Academy of Sciences, makes clear that while average global temperature has been steadily rising due to a warming climate (up about 1.5 degrees Fahrenheit in the past century), the extremes are actually becoming much more frequent and more intense worldwide.

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,

"a new first for mankind – the 'extinction' of an entire ecosystem"

The predicted decline is mainly down to climate change and ocean acidification, though local activities such as overfishing, pollution and coastal development have also harmed the reefs. The book, Our Dying Planet, published by University of California Press, contains further alarming predictions, such as the prospect that "we risk having no reefs that resemble those of today in as little as 30 or 40 more years"

since the 1970s, the frequency of wildfires has increased at least four-fold, and the total size of burn areas has increased at least six-fold in the western United States alone. Steadily rising, the U.S.'s bill for fighting wildfires now totals $1.5 billion per year

the paper presents a new framework for considering wildfires based on the Earth's pre-human fire history, ways that humans have historically used and managed fire and ways that they currently do so.

This research emphasizes the importance of understanding the relative influences of climate, human ignition sources and cultural practices in particular environments in order to design sustainable fire management practices that protect human health, property and ecosystems.
