Deepwater Horizon Oil Spill Contaminated Ocean's Food Chain, Study Finds -- Health & We... - 0 views
-
A recent study has confirmed that toxic compounds derived from oil that was released in the Deepwater Horizon spill that occurred in the Gulf of Mexico nearly two years ago has entered the ocean's food chain through microorganisms.
-
The study, funded by the National Science Foundation and led by a team of researchers from East Carolina University, the University of Maryland Center for Environmental Science, Oregon State University, Georgia Institute of Technology, and the U.S. Geological Survey, detected chemical compounds found in oil called hydrocarbons, some known to be carcinogenic, within the bodies of microscopic crustaceans called zooplankton.

"Our research helped to determine a 'fingerprint' of the Deepwater Horizon spill--something that other researchers interested in the spill may be able to use," Dr. Siddhartha Mitra of East Carolina University said in a statement. "Furthermore, our work demonstrated that zooplankton in the Northern Gulf of Mexico accumulated toxic compounds derived from the Macondo well." Zooplankton form the base of the ocean's food web and are typically fed upon by fish larva and smaller crustaceans, said Dr. David Kimmel of East Carolina University. Whether or not these larger organisms have accumulated significant amounts of toxic compounds, or has entered the human food chain, has yet to be determined. "That is certainly one of the questions we would like to see answered with more research," said Dr. Mitra in a phone interview.

Nuclear Risks at Bed, Bath & Beyond Show Dangers of Scrap [20Mar12] - 0 views
-
The discovery of radioactive tissue boxes at Bed, Bath & Beyond Inc. (BBBY) stores in January raised alarms among nuclear security officials and company executives over the growing global threat of contaminated scrap metal.
-
While the U.S. home-furnishing retailer recalled the boutique boxes from 200 stores nationwide without any reports of injury, the incident highlighted one of the topics drawing world leaders to a nuclear security meeting in Seoul on March 26-27. The bi-annual summit, convened by President Barack Obama for the first time in 2010, seeks to stem the flow of atomic material that has been lost, stolen or discarded as trash.

As U.S. and European leaders tackle the proliferation of weapons-grade uranium or plutonium in countries like Iran and North Korea, industries are confronting the impact of loose nuclear material in an international scrap-metal market worth at least $140 billion, according to the Brussels-based Bureau of International Recycling. Radioactive items used to power medical, military and industrial hardware are melted down and used in goods, driving up company costs as they withdraw tainted products and threatening the public’s health. ‘Major Risk’ “The major risk we face in our industry is radiation,” said Paul de Bruin, radiation-safety chief for Jewometaal Stainless Processing BV, one of the world’s biggest stainless- steel scrap yards. “You can talk about security all you want, but I’ve found weapons-grade uranium in scrap. Where was the security?”

The supposed ‘consensus’ on man-made global warming is facing an inconvenient challenge after the release of new temperature data showing the planet has not warmed for the past 15 years.The figures suggest that we could even be heading for a mini ice age to rival the 70-year temperature drop that saw frost fairs held on the Thames in the 17th Century.Based on readings from more than 30,000 measuring stations, the data was issued last week without fanfare by the Met Office and the University of East Anglia Climatic Research Unit. It confirms that the rising trend in world temperatures ended in 1997.

Meanwhile, leading climate scientists yesterday told The Mail on Sunday that, after emitting unusually high levels of energy throughout the 20th Century, the sun is now heading towards a ‘grand minimum’ in its output, threatening cold summers, bitter winters and a shortening of the season available for growing food.Solar output goes through 11-year cycles, with high numbers of sunspots seen at their peak. We are now at what should be the peak of what scientists call ‘Cycle 24’ – which is why last week’s solar storm resulted in sightings of the aurora borealis further south than usual. But sunspot numbers are running at less than half those seen during cycle peaks in the 20th Century.
-
Analysis by experts at NASA and the University of Arizona – derived from magnetic-field measurements 120,000 miles beneath the sun’s surface – suggest that Cycle 25, whose peak is due in 2022, will be a great deal weaker stil

Man-made carbon emissions have acidified the world's oceans far beyond their natural levels, new research suggests.In some regions, acidity levels rose faster in the last two centuries than it did in the previous 21,000 years, a study from the University of Hawaii has shown.Ocean acidity makes it harder for organisms such as molluscs and coral to construct the protective layers they need to survive.
Arctic Ocean freshwater bulge detected [22Jan12] - 0 views
-
UK scientists have detected a huge dome of freshwater that is developing in the western Arctic Ocean. The bulge is some 8,000 cubic km in size and has risen by about 15cm since 2002. The team thinks it may be the result of strong winds whipping up a great clockwise current in the northern polar region called the Beaufort Gyre. This would force the water together, raising sea surface height, the group tells the journal Nature Geoscience.
-
The data (1995-2010) indicates a significant swelling of water in the Beaufort Gyre, particularly since the early part of the 2000s. The rising trend has been running at 2cm per year.
-
A lot of research from buoys and other in-situ sampling had already indicated that water in this region of the Arctic had been freshening. This freshwater is coming in large part from the rivers running off the Eurasian (Russian) side of the Arctic basin. Winds and currents have transported this freshwater around the ocean until it has been pulled into the gyre. The volume currently held in the circulation probably represents about 10% of all the freshwater in the Arctic.

Bees being turned into 'zombies' by parasite -- Science & Technology -- Sott.net - 0 views
-
Honey bees are abandoning their hives and being turned into "zombies" by a deadly fly parasite in their stomachs. The parasite makes the bees flee their hives and then walk round and round in circles before dying. It also makes them seek out bright lights. The parasite lays its' eggs inside the abdomen of the honey bee. About a week after the bee dies, the pupae emerge from the throats and heads of the dead bees.
-
Scientists discovered the parasite by accident but they believe it may help them discover what is causing colony collapse disorder which is devastating honey bees in Europe and America cutting some populations in half. Biology professor John Hafernik, of San Francisco State University, discovered the parasite by accident when collecting bees. Researchers found that after being invaded by the parasite, the bees abandon their hives in what is literally a flight of the living dead to congregate near lights.
'Lost world' discovered around Antarctic vents - 0 views
-
Communities of species previously unknown to science have been discovered on the seafloor near Antarctica, clustered in the hot, dark environment surrounding hydrothermal vents.
-
The discoveries, made by teams led by the University of Oxford, University of Southampton, the National Oceanography Centre, and British Antarctic Survey, include new species of yeti crab, starfish, barnacles, and sea anemones, and even an octopus probably new to science.
-
For the first time researchers, using a Remotely Operated Vehicle (ROV), have been able to explore the East Scotia Ridge deep beneath the Southern Ocean where hydrothermal vents, including 'black smokers' reaching temperatures of up to 382 degrees Celsius, create a unique environment lacking sunlight but rich in certain chemicals. The team report their findings in this week's PLoS Biology.

The National Oceanic and Atmospheric Administration declared a recent rash of seal deaths to be an "unusual mortality event" on Tuesday. More than 60 seals have died and 75 found diseased in Alaska with skin sores and patchy hair loss. The Fish and Wildlife Service has also identified diseased and dead walruses. A similar official declaration for Pacific Walrus in Alaska is pending. The walruses have suffered from similar symptoms, which have also included labored breathing and appearing lethargic. Scientists have yet to identify a cause for this disease, but tests have indicated that it is not a virus. Hunters, meanwhile, continue to see many healthy animals. Despite a significant contact with seals and walruses, no humans have reported similar symptoms. However, it is not known whether the disease can be transmitted to humans or other animals. In most cases, necropsies and lab tests have revealed skin lesions, fluid in the lungs, white spots on the liver, and abnormal growths in the brain. Some of the seals and walruses have undersized lymph nodes, possibly a sign of weakened immuned systems. In Canada and Russia, ringed seals have been reported suffering similar symptoms. It is unknown whether they are related.

Mexico drought is worst in 70 years [06Dec11] - 0 views
-
Crops of corn, beans and oats are withering in the fields. About 1.7 million cattle have died of starvation and thirst. Hardest hit are five states in Mexico's north, a region that is being parched by the same drought that has dried out the southwest United States. The government is trucking water to 1,500 villages scattered across the nation's northern expanse, and sending food to poor farmers who have lost all their crops. Life probably won't improve soon. The next rainy season isn't due until June, and there's no guarantee normal rains will come then. Most years, Guillermo Marin harvests 10 tons of corn and beans from his fields in this harsh corner of Mexico. This year, he got just a single ton of beans. And most of the 82-year-old farmer's fellow growers in this part of Durango state weren't able to harvest anything at all.

Steve Hilton, the Prime Minister's director of strategy and 'green guru', is the latest person to admit to doubts about climate change. 'I'm not sure I believe in it,' he announced at a meeting of the Energy Department, prompting one aide to blurt out: 'Did I just hear that correctly?' According to one witness, Hilton, 41, the man who coined the slogan 'Vote Blue and Go Green' and changed the Tory symbol from a Stalinist style torch to an eco friendly tree, said: 'Climate change arguments are highly complex.
Outcry over EU budget plan - Earth Monitoring Cuts - 0 views
-
As Europe’s financial crisis deepens, a storm is also brewing over proposals that would change how two giant science and technology projects are funded. Both ITER — the international effort to build a fusion-energy test reactor — and an ambitious Earth-observation project called the Global Monitoring for Environment and Security (GMES) programme are too costly to remain under the general budget of the European Union (EU), according to proposals from the European Commission. The solution, it says, is to corral funding for both projects separately from the next general budget, which will span 2014–20.
-
The commission suggests that the projects — along with future large-scale science programmes — be supported through new intergovernmental organizations. EU member states would fund these bodies, perhaps along with an additional, capped contribution from the EU budget. This arrangement would reduce the main EU budget’s exposure to the large cost overruns that are common in big science projects, the commission argues.
-
the proposal “would only lead to the weakening of these two projects both in terms of funding and governance”. The proposal is likely to go through tortured negotiations between the commission, the Council of Ministers and the European Parliament right up until the 2014 budget settlement.
Breakthrough in the Macondo Mystery: BP Admits to New Activity at Deepwater Horizon Sit... - 0 views
-
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.
Scientists in Revolt against Global Warming [27Nov11] - 0 views
-
Global warming became a cause to save life on earth before it had a chance to become good science. The belief that fossil fuel use is an emergency destroying our planet by CO2 emissions took over the media and political arena by storm. The issue was politicized so quickly that the normal scientific process was stunted. We have never had a full, honest national debate on either the science or government policy issues. Everyone "knows" that global warming is true. The public has no idea of the number of scientists -- precisely one thousand at last count of a congressional committee -- who believe that global warming is benign and natural, and that it ended in 1998. We have not been informed of the costs to our economy of discouraging fossil fuel development and promoting alternatives. The public need to know the choices being made on their behalf, and to have a say in the matter. We are constantly told that the scientific and policy debate on global warming is over. It has just begun.

The worst hurricanes were in 1926, the second-worst in 1900. The world's top hurricane experts say that there is no evidence that global warming affects storms.
-
More and more scientists are revolting against the global warming consensus enforced by government funding, the academic establishment, and media misrepresentation. They are saying that solar cycles and the complex systems of cloud formation have much more influence on our climate, and account for historical periods of warming and cooling much more accurately that a straight line graph of industrialization, CO2, and rising temperatures. They also point out that the rising temperatures that set off the global warming panic ended in 1998.
