(03/06/2008) Sea levels were 550 feet (170 m) higher in the late Cretaceous period, about 80 million years ago, than today, shows a new reconstruction of historic ocean basins published in the journal Science. The authors say the work may help model current global warming-driven sea level change.
Toyota, GM: Hydrogen fuels cells are not viable
(03/05/2008) Executives from General Motors Corp. and Toyota Motor cast doubts yesterday about the viability of hydrogen fuel cells for mass-market production in the near term, reports The Wall Street Journal. The executives said electric cars will be a better way to cut emissions and improve fuel efficiency.
Scientists seek to understand how climate will impact forest carbon
(03/05/2008) Forests contain nearly 40 percent of the world's carbon--more than the atmosphere contains--but too little is known about forest carbon dynamics to predict whether anthropogenic global change will increase or decrease forest carbon pools. Helene Muller-Landau, staff scientist at the Smithsonian Tropical Research Institute, announced a major global research effort to quantify forest carbon pools and fluxes. She announced the new effort at the Climate Change in the Americas Symposium, held Feb. 25-29 at the institute's headquarters in Panama.

Why Europe torpedoed the REDD forests-for-carbon credits initiative
(03/05/2008) Reducing emissions from deforestation and forest degradation (REDD) has been widely lauded as a mechanism that could fund forest conservation and poverty alleviation efforts while fighting climate change. At the December U.N. climate meeting in Bali, delegates agreed to include REDD in future discussions on a new global warming treaty — a move that could eventually lead to the transfer of billions of dollars from industrialized countries to tropical nations for the purpose of slowing greenhouse gas emissions by reducing deforestation rates. conservationists and scientists applauded the decision.

Human impacts on primate conservation in central Amazonia
(03/03/2008) Deforestation in the Amazon is a serious concern. In the Brazilian Amazon, forests are cleared for cattle ranches, soybean cultivation, and selective logging practices. A new plan to settle approximately 180 families north of Manaus, the capital city of the state of Amazonas, has created widespread controversy. The land plots would be located within the study site of the longest-running study of forest fragmentation, the Biological Dynamics of Forest Fragments Project (BDFFP). Therefore, the plan would threaten scientific research at the BDFFP and other nearby research sites operated by the Instituto Nacional da Pesquisas de Amazônia (INPA) and Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA), as well as the future of the Central Amazonian conservation Corridor.
China's tropical rainforests decline 67% in 30 years

New 'red list' seeks to stave off global seafood collapse
(03/03/2008) Over-fishing and destructive fishing practices have had a considerable effect on oceanic ecosystems. In 2006 a highly-reported study found that without drastic measures all wild seafood will disappear from the oceans in 50 years. Greenpeace, working against such a crash, has started a campaign that highlights 'red fish'. The twenty-two 'red' species are seafood that consumers and suppliers (including supermarkets) should avoid due to their plummeting populations and/or the damage caused by harvesting them.
Fewer wolves may mean fewer pronghorn in Yellowstone
(03/03/2008) As western states debate removing the gray wolf from protection under the Endangered Species Act, a new study by the Wildlife conservation Society cautions that doing so may result in an unintended decline in another species: the pronghorn, a uniquely North American animal that resembles an African antelope.

How accurate is long-term climatology data from the Amazon?
(03/03/2008) With some models forecasting significant change in the Amazon rainforest over the next century, it has been unclear whether the temperature and precipitation data upon which the projections are made is accurate. Now, new research by Rafael Rosolem of the University of Arizona, shows that data associated with the Large-scale Biosphere-Atmosphere Experiment in Amazon (LBA) -- an international research initiative focusing on how changes in land use and climate will affect the biological, physical, and chemical functioning of Amazonia -- is representative of normal climatology for the region. In other words, during most of the LBA data collection period, the data was not taken during severe drought or extreme wet periods.

Saving forgotten species: An interview with Carly Waterman, Program Coordinator of EDGE
(02/28/2008) In January 2007 a new conservation initiative arrived with an unusual level of media attention. The attention was due to the fact that the organization was doing things differently—very differently. Instead of focusing their efforts on the usual conservation-mascots like the panda or tiger, they introduced the public to long-ignored animals: photos of the impossibly unique aye-aye and a baby slender loris wrapped around a finger appeared in newsprint worldwide. The new initiative EDGE (Evolutionary Distinct and Globally Endangered), launched by the Zoological Society of London, was not concerned with an animal's perceived popularity, rather the chose their focal species on a combined measurement of a species' biological uniqueness and its vulnerability to extinction. Consequently, they hoped to make celebrities out of animals (big and small) most people had never heard of: the hairy-eared dwarf lemur, anyone?
Web site offers homepage for every one of Earth's species
(02/27/2008) Monumental may be the only way to properly describe the Internet's Encyclopedia of Life. Its creators have set themselves the task of gathering accurate and detailed information on the earth's known 1.8 million species until every tree, arachnid, rodent, and even virus will have its own in-depth webpage.
Half the Amazon rainforest will be lost within 20 years
(02/27/2008) More than half the Amazon rainforest will be damaged or destroyed within 20 years if deforestation, forest fires, and climate trends continue apace, warns a study published in Philosophical Transactions of the Royal Society B. Reviewing recent trends in economic, ecological and climatic processes in Amazonia, Daniel Nepstad and colleagues forecast that 55 percent of Amazon forests will be "cleared, logged, damaged by drought, or burned" in the next 20 years. The damage will release 15-26 billion tons of carbon into the atmosphere, adding to a feedback cycle that will worsen both warming and forest degradation in the region. While the projections are bleak, the authors are hopeful that emerging trends could reduce the likelihood of a near-term die-back. These include the growing concern in commodity markets on the environmental performance of ranchers and farmers; greater investment in fire control mechanisms among owners of fire-sensitive investments; emergence of a carbon market for forest-based offsets; and the establishment of protected areas in regions where development is fast-expanding.
Small fires a big threat to Amazon rainforest biodiversity

A Doomsday Vault for Frogs?
(02/27/2008) The Amphibian Ark, a doomsday vault for amphibians, will highlight Leap Day, February 29th, to recognize 2008 as the Year of the Frog. The campaign seeks to raise awareness of the global plight of frogs and other amphibians threatened by habitat loss, climate change, pollution and an emergent disease. Joining in the effort is the Wildlife conservation Society?s (WCS) Bronx Zoo and New York Aquarium, facilities that house some of the world's most threatened amphibians.
Organic fertilizers could fight global warming
(02/27/2008) Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions, according to new research published in a special issue of Waste Management & Research (Special issue published today by SAGE).
Complete map of world forests to help REDD carbon trading initiative
(02/27/2008) Policymakers, conservationists and scientists have high hopes that REDD, a mechanism for compensating countries for reducing emissions from deforestation and forest degradation, will spur a massive flow of funds to tropical countries, helping preserve rainforests and delivering economic benefits to impoverished rural communities. To date, one of the biggest hurdles for the initiative has been establishing a baseline for deforestation rates -- in order to compensate countries for "avoided deforestation" it first must be known how much forest the country has been losing on a historical basis. Until now, with some notable exceptions, this data was based largely on spotty satellite assessment and surveys of national forestry departments by the U.N. Food and Agricultural Organization.
$100 billion worth of carbon released from deforestation in Riau, Sumatra
(02/27/2008) A WWF study found that deforestation of nearly 10.5 million acres of tropical forests and peat swamp in central Sumatra's Riau Province over the past 25 years has generated 3.7 gigatons of carbon dioxide. Based on today's $32 closing price for a ton of carbon dioxide for European Union Allowances, the emissions had a theoretical trading value of $118 billion, assuming they could have been traded at the full E.U. carbon price at the time (voluntary offsets would have been worth about $13 billion).
Carbon trading could protect forests, reduce rural poverty
(02/26/2008) Carbon trading from avoided deforestation (REDD) credits could yield billions of dollars for tropical countries, according to analysis by mongabay.com, a leading tropical forest web site.
Soil erosion: the future of Easter Island
(02/25/2008) Today the saga that is Easter Island's past is well known. The tragic circumstances that led to the downfall of its early civilization through starvation and war are of epic proportions. Many scientists agree that the real life scenario born from this isolated island serves as a warning, about the interrelatedness between scarcity of natural resources and conflict, for all mankind. However, current natural resource practices suggest that this lesson has fallen on deaf ears.
Deep-sea krill discovered in Antarctica
(02/25/2008) Antarctic krill have been found living at depths up to 3000 meters near the Antarctic Peninsula, a finding that changes scientists' understanding of a fundamental part of the ocean food chain. Previously researchers believed that krill lived only in the upper ocean.

Reducing deforestation rates 10% could generate $13B in carbon trading under REDD
(02/25/2008) Cutting global deforestation rates 10 percent could generate up to $13.5 billion in carbon credits under a reducing emissions from deforestation ("REDD") initiative approved at the U.N. climate talks in Bali this past December, estimate researchers writing in Philosophical Transactions of the Royal Society B. But the researchers caution there are still substantial obstacles to overcome before carbon-credits-for-rainforest-conservation becomes a reality.
Rainforest logging threatens endangered sea turtles
(02/25/2008) Logging is having an unexpected impact on endangered sea turtles in Central Africa, reports a new study published in Oryx. Aerial surveys in Gabon reveal that logs lost during transport are clogging beaches, preventing critically endangered leatherback turtles (Dermochelys coriacea) from nesting.
Amazon rainfall linked to Atlantic Ocean temperature
(02/25/2008) Climate models increasingly forecast a dire future for the Amazon rainforest. These projections are partly based on recent research that has linked drought in the Amazon to sea surface temperatures in the tropical Atlantic. As the tropical Atlantic warms, the southern Amazon -- the agricultural heartland of Brazil -- may see higher temperatures and less rainfall.
Deforestation a greater threat to the Amazon than global warming
(02/25/2008) If past conditions are any indication of future conditions, the Amazon rainforest may survive considerable drying and warming caused by global warming, argue researchers in a paper published in Philosophical Transactions of the Royal Society B.
Widespread butterflyfish may go extinct due to global warming, pollution
(02/24/2008) The Chevroned Butterflyfish, a colorful fish found in tropical oceans around the world, faces extinction due to overexploitation, pollution and climate change, report researchers writing in the journal Behavioural Ecology and Sociobiology. Despite its widespread distribution, the species could be doomed by its specialized feeding habitats: the Chevroned Butterflyfish (Chaetodon trifascialis) feeds on only one type of coral.
Amazon research and conservation cannot ignore social issues
(02/24/2008) For Amazonian conservation to be effective it must start paying more attention to social issues according to a new paper: Taking things public: a contribution to address human dimensions of environmental change. The paper's author, Dr. Diogenes Alves, of the National Institute for Space Research told mongabay.com that "the main point of this paper is that it became crucial to recognize the social, economic and political settings associated with environmental change in the Amazon."
