794 species on brink of extinction find study
(12/12/2005) Protecting 595 sites around the world would help address an imminent global extinction crisis, according to a study published today in the Proceedings of the National Academy of Sciences. Conducted by scientists working with the 52 member organizations of the Alliance for Zero Extinction (AZE), the study identifies 794 species threatened with imminent extinction by virtual of existing at only a single remaining site on Earth. The study found that just one-third of the sites are known to have legal protection, and most are surrounded by human population densities that are approximately three times the global average. Safeguarding these sites is key to saving these species from extinction say the authors of the study.
Norwegian killer whales most toxic mammals in Arctic
(12/12/2005) Initial scientific results show Norwegian killer whales are the most toxic mammals in the Arctic, says WWF, the global conservation organization.

(12/05/2005) Facing a plague of piracy off the Horn of Africa that has closed its usual supply lines by sea, the United Nations World Food programme (WFP) today announced the arrival in southern Somalia of its first overland truck convoy carrying food aid in almost five years, and called for urgent funding to make up for the increased costs.
Temperate forests may worsen global warming, tropical forests fight higher temperatures
(12/05/2005) Growing a forest might sound like a good idea to combat global warming, since trees draw carbon dioxide from the air and release cool water from their leaves. But they also absorb sunlight, warming the air in the process. According to a new study from the Carnegie Institution's Department of Global Ecology and Lawrence Livermore National Laboratory, planting forests at certain latitudes could make the Earth warmer.
Soil moisture, root depth influence climate models
(12/05/2005) By soaking up moisture with their roots and later releasing it from their leaves, plants play an active role in regulating the climate. In fact, in vegetated ecosystems, plants are the primary channels that connect the soil to the atmosphere, with plant roots controlling the below-ground dynamics.
Companies increasingly at risk for climate change litigation says UN
(12/05/2005) Companies which contribute to climate change will increasingly face legal action according to a U.N.-sponsored report accounced last week but scheduled for released in March 2006. London-based law firm Freshfields is working with Dutch bank ABN Amro to produce the U.N. report which aims to encourage investors to address environmental, social and governance issues in their investment decisions.
Warming could free far more carbon from high Arctic soil than earlier thought
(12/05/2005) Scientists studying the effects of carbon on climate warming are very likely underestimating, by a vast amount, how much soil carbon is available in the high Arctic to be released into the atmosphere, new University of Washington research shows. A three-year study of soils in northwest Greenland found that a key previous study greatly underestimated the organic carbon stored in the soil. That's because the earlier work generally looked only at the top 10 inches of soil, said Jennifer Horwath, a UW doctoral student in Earth and space sciences.
Congo rainforest - 600,000 sq km slated for logging
(12/05/2005) The World Bank will meet Thursday to decide whether it will fund large-scale logging in the Democratic Republic of Congo's rainforests. The country, home to the second largest rainforest in the world after Brazil, is emerging from years of civil strife which resulted in the deaths of some 3.8 million people from violence and disease.
Amazon rainforest biodiversity due to biology not climate change says study
(12/05/2005) The biodiversity of the Amazon rainforest results from biological factors, not climate change as widely thought, says new research published in the journal Proceedings of the Royal Society B. Scientists have long argued that the species richness of tropical forests could be due to climate change-induced fragmentation, known as the "forest refuge: theory, and other external factors that caused geographic isolation. Now, researchers from University College London say that biological influences play a greater role in driving species evolution.
Elephant drunk from fruit not likely, finds study

Amazon deforestation slows in Brazil for 2005
(12/05/2005) Deforestation in the Amazon rainforest fell 37% for the 2004-2004 year according to Brazilian government figures released today. Between July 2004 and August 2005, 7,298 square miles of rainforest (18,900 square kilometers) -- an area almost half the size of Switzerland -- were destroyed. Last year the figure was 10,088 square miles (26,129 sq km kilometers) and since 1978 some 206,250 square miles (534,200 sq km) of forest has been lost.
70 years after logging, forests don't hold as much carbon as original forests
(12/05/2005) New research out of Ohio State University suggests that following logging, temperate forests take long periods of time to recover their carbon storing capacity. The scientists examined forests of of the upper Great Lakes region, which were 90% logged at the turn of the century, and found that they store only half the carbon the original forests contained. Poor forest management is blamed for the shortfall.
Energy efficiency helped California grow an extra $31 billion finds study
(12/04/2005) Countering Bush administration claims to the contrary, environmental officials for the state of California and the Brazilian state of Sao Paulo have found significant evidence that greenhouse gas pollution can be substantially reduced at a profit rather than a cost. The study, commissioned by the William and Flora Hewlett Foundation, found that energy efficiency has helped the California economy grow an extra 3 percent - a $31 billion gain - compared to business as usual. Further, the researchers say that each Californian typically saved about $1,000 per year between 1975 and 1995 just through efficiency standards for buildings and appliances.

Change in Atlantic circulation could plunge Europe into cold winters
(12/01/2005) The Atlantic Ocean circulation that carries warm waters north and returns cold waters south is slowing, putting Europe at risk of colder temperatures, according to research published in Nature. The Atlantic Heat Conveyor, the system of currents in the Atlantic Ocean that result in a net transport of warm water into the northern hemisphere, keeps western Europe warmer than regions at similar latitudes in other parts of the world. A weakening of the system, which includes the Gulf Stream, could cause a cooling in northwest Europe.
Biosensor Could Help People with Parkinson's, Alzheimer's Disease
(12/01/2005) An engineering researcher at the University of Arkansas has developed a wireless, implantable biosensor that may one day help physicians treat patients with neurological brain disorders such as Parkinson's Disease, Alzheimer's Disease and epilepsy. Made of carbon nanotubes, the sensor monitors and controls chemicals in the brain and communicates with other sensors to control tremors or direct the movement of prosthetic limbs.
