U.S. EPA announces Palos Verdes Shelf proposed environmental protection plan
June 12, 2009 06:04 AM - Editor, ENN

The U.S. Environmental Protection Agency will host public meetings and accept public comments on its proposed Preferred Alternative plan that addresses the risks to human health and the environment at the Palos Verdes Shelf, located near Los Angeles, Calif. The Palos Verdes Shelf site is a large area of DDT- and PCB-contaminated sediment located in the ocean off the coast of the Palos Verdes peninsula south of Los Angeles. The offshore site stretches from Point Fermin in the southeast to Redondo Canyon in the northwest, a distance of about 9 miles. The EPA’s Preferred Alternative plan is an interim remedy that proposes institutional controls, monitored natural recovery and a containment cap. Construction is expected to take 3 years and cost an estimated $36,000,000.

Population and Sustainability: Can We Avoid Limiting the Number of People?

Slowing the rise in human numbers is essential for the planet--but it doesn't require population control

Green jobs sector 'poised for explosive growth'

Green-collar workers -- who include everyone from energy-efficiency consultants to wastewater plant operators -- constitute a tiny but fast-growing segment of the U.S. economy, according to a study published today by the Pew Charitable Trusts.

Caribbean reefs 'flattened' in just 40 years
June 10, 2009 07:26 AM - Andy Coghlan, New Scientist

In just 40 years, the Caribbean's spectacular branched corals have been flattened. Research reveals that the corals have been replaced by shorter rival species – and points to climate change as at least partly to blame. Most of the reefs have lost all the intricate, tree-like corals that until the 1970s provided sanctuary for unique reef fish and other creatures, as well as protecting coastlines by sapping the energy of waves.

Book Review: GREEN, Your Place in the New Energy Revolution
June 9, 2009 01:50 PM - M Molendyke, ENN

In the last decade or so, Americans have been bombarded by a environmentalist media that is relentless when it comes to highlighting the causes, dangers, and perpetrators of carbon- fueled global climate change. This surge of sensationalism, combined with the perceived lack of ways to “make it better” (outside of the light bulb changing, recycling, hybrid car- buying stories we have heard a thousand times), has lead to a public paralyzed by the thought of an approaching man- made apocalypse. Responding to this stagnation are Jane and Michael Hoffman, a New York City couple who have molded their lives around energy innovation. Their recently published book Green: Your Place in the New Energy Revolution is peppered with lighthearted anecdotes about their own experiences with the green revolution, including a reoccurring allusion to what the couple calls their “Aha!” moment, recognizing the urgency of the climate problem.

USGS Study Links Estrogen to Fish Immunity

Exposure to estrogen reduces production of immune-related proteins in fish. This suggests that certain compounds, known as endocrine disruptors, may make fish more susceptible to disease.

A World First – Tankers on Shore Power when at Dock
June 5, 2009 12:10 PM - , Triple Pundit

A major source of air pollution in port areas comes from the giant vessels that tie up at their docks to load and unload cargo. That’s because the powerful diesel engines have to run continuously to keep the ships’ equipment and support systems operating. That also means continuous spewing of GHG and diesel particulate emissions into the local air. A solution to this massive emissions problem has long existed but is not widely implemented because it involves expensive modifications both on-ship and to offshore facilities. It’s called shore power, which allows ships to shut down their diesel engines at berth and literally plug into the landside electricity grid, thus improving air quality.

Huge Waves Detected in Atmosphere

Researchers have detected giant, fast-moving waves of air, caused by thunderstorms and other disturbances, above Poker Flat, Alaska, where a new radar is churning out the first three-dimensional images of upper atmospheric phenomena in the polar region.

Green energy overtakes fossil fuel investment, says UN

Green energy overtook fossil fuels in attracting investment for power generation for the first time last year, according to figures released today by the United Nations.

Analysis Finds Elevated Risk From Soot Particles in the Air

A new appraisal of existing studies documenting the links between tiny soot particles and premature death from cardiovascular ailments shows that mortality rates among people exposed to the particles are twice as high as previously thought.
