Biology Breach

When marine ecologist Andres Cozar Cabanas and a team of researchers completed the first ever map of ocean trash, something didn't quite add up.
Their work, published this month in the Proceedings of the National Academy of Sciences, did find millions of pieces of plastic debris floating in five large subtropical gyres in the world's oceans. But plastic production has quadrupled since the 1980s, and wind, waves, and sun break all that plastic into tiny bits the size of rice grains. So there should have been a lot more plastic floating on the surface than the scientists found.
"Our observations show that large loads of plastic fragments, with sizes from microns to some millimeters, are unaccounted for in the surface loads," says Cozar, who teaches at the University of Cadiz in Spain, by e-mail. "But we don't know what this plastic is doing. The plastic is somewhere--in the ocean life, in the depths, or broken down into fine particles undetectable by nets."

A national environmental group has released a study indicating two area rivers are among the top 10 waterways for total toxic discharge... The bulk of the New River's 14 million pounds of toxic discharge is largely the result of the U.S. Army Radford Army Ammunition plant in Radford, Va. The study claims the plant is responsible for more than 13.6 million pounds of toxic pollutants into the New River.
Calls to the West Virginia Department of Environmental Protection office in Parkersburg were referred to Charleston. After several days of leaving messages, officials in Charleston referred questions to Melyssa Savage, Title III program manager for the West Virginia Division of Homeland Security and Emergency Management Agency. Savage was out of the office.

Environmental groups say the oil leak spilling into the Timor Sea should be declared a national emergency, with one expert likening it to a "disaster movie."
The situation has worsened in the last 24 hours with a fire breaking out on the deck of the West Atlas rig and Montara well head platform, when the company responsible for its operation began to plug the rig's leak below the sea bed with mud.

Climate Chaos
November 2, 2013, from The Earth Institute at Columbia University
A recent slowdown in global warming has led some skeptics to renew their claims that industrial carbon emissions are not causing a century-long rise in Earth's surface temperatures. But rather than letting humans off the hook, a new study in the leading journal Science adds support to the idea that the oceans are taking up some of the excess heat, at least for the moment. In a reconstruction of Pacific Ocean temperatures in the last 10,000 years, researchers have found that its middle depths have warmed 15 times faster in the last 60 years than they did during apparent natural warming cycles in the previous 10,000.

A huge, emerging crack has been discovered in one of Antarctica's glaciers, with a NASA plane mission providing the first-ever detailed airborne measurements of a major iceberg breakup in progress... The crack was found in Pine Island Glacier, which last calved a significant iceberg in 2001; some scientists have speculated recently that it was primed to calve again. But until an Oct. 14 IceBridge flight, no one had seen any evidence of the ice shelf beginning to break apart. Since then, a more detailed look back at satellite imagery seems to show the first signs of the crack in early October...When the iceberg breaks free, it will cover about 340 square miles (880 square kilometers) of surface area. Radar measurements suggested the ice shelf in the region of the rift is about 1,640 feet (500 meters) feet thick, with only about 160 feet of the shelf floating above water and the rest submerged.

...Senior officials and negotiators are increasingly gloomy about the prospects for a global warming deal next month, with the British government admitting there is now no chance of a legally binding treaty.
Speaking as officials gather in Barcelona tomorrow for a final round of negotiations, Rajendra Pachauri, head of the Intergovernmental Panel on Climate Change, said: "I gave all the world's leaders a very grim view of what the science tells us and that is what should be motivating us all, but I'm afraid I don't see too much evidence of that at the current stage.
"Science has been moved aside and the space has been filled up with political myopia with every country now trying to protect its own narrow short-term interests. They are afraid to have negotiations go any further because they would have to compromise on those interests."

Recovery

The sun's activity is in free fall, according to a leading space physicist. But don't expect a little ice age. "Solar activity is declining very fast at the moment," Mike Lockwood, professor of space environmental physics at Reading University, UK, told New Scientist. "We estimate faster than at any time in the last 9300 years."
Lockwood and his colleagues are reassessing the chances of this decline continuing over decades to become the first "grand solar minimum" for four centuries. During a grand minimum the normal 11-year solar cycle is suppressed and the sun has virtually no sunspots for several decades. This summer should have seen a peak in the number of sunspots, but it didn't happen.
Lockwood thinks there is now a 25 per cent chance of a repetition of the last grand minimum, the late 17th century Maunder Minimum, when there were no sunspots for 70 years.

From the cotton field in rural India to the local rag bin, a typical pair of blue jeans consumes 919 gallons of water during its life cycle, Levi Strauss & Company says, or enough to fill about 15 spa-size bathtubs. That includes the water that goes into irrigating the cotton crop, stitching the jeans together and washing them scores of times at home. The company wants to reduce that number any way it can, and not just to project environmental responsibility. It fears that water shortages caused by climate change may jeopardize the company's very existence in the coming decades by making cotton too expensive or scarce.

Indiana University biologists have uncovered how a control system works in producing the important light-harvesting antennae that power photosynthesis in cyanobacteria, the microorganisms that are progenitors of all land plants and responsible for nearly half of the Earth's current oxygen production. Implications of fully comprehending the mechanism, called "light-regulated transcription attenuation," include the potential for increasing agricultural yields, making bio-solar energy production more feasible, and improving understanding of a globally important biological process that is vital for providing the energy needed to sustain virtually all life on Earth...
