Wood chemistry used to track origin of timber

(12/18/2008) A researcher is using carbon and oxygen isotopes to track the origin of timber as part of a worldwide effort to develop methods to combat illegal logging.


Japanese scientists use goldfish to screen for freshwater pollution

(12/17/2008) Coal miners used canaries to warn them of noxious gases for generations. Today's substitute may be the everyday goldfish: It can act as an aquatic canary to warn scientists when something bad is brewing in the waters, according to new research.


Arctic sea ice fell to the lowest volume on record in 2008

(12/17/2008) Arctic sea ice fell to the lowest volume — and second lowest extent — on record, according to the annual World Meteorological Organization (WMO) Statement on the Status of the Global Climate.


Biochar and its Role in Mitigating Climate Change

(12/17/2008) The growing concerns about climate change have brought biochar, a charcoal produced from biomass combustion, into limelight. Biochar is a carbon-rich, fine-grained residue which can be produced either by ancient techniques (such as covering burning biomass with soil and allowing it to smolder) or state-of-the-art modern pyrolysis processes. Combustion and decomposition of woody biomass and agricultural residues results in the emission of a large amount of carbon dioxide. Biochar can store this CO2 in the soil leading to reduction in GHGs emission and enhancement of soil fertility. Biochar holds the promise to tackle chronic human development issues like hunger and food insecurity, low agricultural productivity and soil depletion, deforestation and biodiversity loss, energy poverty, air pollution and climate change. Thus, biochar could make a difference in the energy-starved countries of Asia, Africa and Latin America as well as the industrialized world with its vast array of benefits.


Tool helps overcome miles-per-gallon illusion

(12/17/2008) A new tool helps motorists evaluate the fuel efficiency of their vehicle in terms that more accurately reflect the cost of driving than miles-per-gallon (MPG).


Observed sea level rise, ice melt far outpaces projections

(12/17/2008) Sea levels will rise faster than previously estimated due to rapid melting of glaciers and ice sheets, according to a U.S government report released at the annual meeting of the American Geophysical Union in San Francisco. The report, titled Abrupt Climate Change, incorporates research published since last year's Intergovernmental Panel on Climate Change (IPCC) report, which drew largely from studies dating up to 2006. Most significantly, Abrupt Climate Change suggests that IPCC estimates for future sea level rise (18-58 cm) are conservative, noting that recent observations on sea level rise and loss of sea ice are far outpacing previous projections.


Greenland melting much faster than last year

(12/16/2008) Greenland is losing ice three times faster than last year, report researchers presenting at the meeting of the American Geophysical Union in San Francisco.


Africa eyes geothermal power

(12/15/2008) Geothermal — the tapping of steam from hot underground rocks — could provide a source of clean, renewable energy in parts of Africa where electricity is currently limited, according to an assessment by the United Nations Environment Program (UNEP) and the Global Environment Facility (GEF).


Corn expansion is hurting ladybugs

(12/15/2008) Expansion of corn acreage to meet ethanol targets is reducing the ability of beneficial insects to control pests, a loss valued at $58 million in the four states studied (Michigan, Iowa, Minnesota and Wisconsin), report researchers writing in the journal Proceedings of the National Academy of Sciences.


Climate change, ocean acidification may doom jumbo squid

(12/15/2008) Ocean acidification — driven by rising carbon dioxide levels in the atmosphere — may hurt the Humboldt squid, report researchers writing in the journal Proceedings of the National Academy of Sciences.


Photos of new species discovered in the Greater Mekong

(12/15/2008) More than 1,000 previously unknown species have been discovered in the Greater Mekong, a region comprising Cambodia, Laos, Myanmar (Burma), Thailand, Vietnam and the Yunnan Province of China, in the past decade, according to a new report from WWF.


Neither slow nor stupid, manatees are killed by boats because they can't hear them

(12/12/2008) Last year 73 manatees were killed by boats in Florida, despite two decades of manatee-related protections. In fact, manatee deaths due to boat collisions have only increased since protections were implanted. A recent study at the Florida Atlantic University has finally revealed why boats are so dangerous to manatees: the manatee cannot run from what it does not hear.


Computer hackers are helping illegal loggers destroy the Amazon rainforest

(12/12/2008) Computer hackers are helping illegal loggers destroy the Amazon rainforest by breaking into the Brazilian government's timber tracking system and altering the records so as to increase logging allocations, reports Greenpeace.


Lula pledges big cuts in Amazon deforestation -- after he leaves office

(12/12/2008) Last week Brazil unveiled plans to cut deforestation substantially from a 1996-2005 baseline of 19,533 square kilometers per year. The announcement met a mixed response from conservationists. Some applauded the decision to set hard targets for reducing deforestation, others say the targets were too low and that the country should aim for zero net deforestation by 2015. Nevertheless as more details have emerged, it becomes clear that the onus for reining in deforestation falls on Brazilian President Luiz Inacio Lula da Silva's successor.


Rainforests continue to fall but hope may rest in a market solution

(12/11/2008) Environmentalists attempting to preserve the vanishing Amazon rain forest now confront a stark paradox: Never before have they succeeded in protecting so much of the world’s largest tropical forest, yet never before has so much of it simultaneously been destroyed. The key question today is whether new models of conservation — including an increasingly popular, market-based program known as REDD — will be able to reverse the steady loss of tropical forests, not only in the Amazon, but also in Indonesia, Borneo, and Africa’s Congo basin, where virgin woodlands continue to be razed at an unprecedented rate.


Climate change will transform the chemical-makeup of the ocean

(12/11/2008) By studying the ocean’s past, scientists have discovered that climate change has a much larger affect on ocean chemistry than expected. The study, published in Science, reveals that 13 million years ago climate change significantly altered the chemical composition of the oceans. Such changes in the ocean’s chemical makeup today could have a great impact on marine life, already stressed by overfishing and pollution.


Chad's elephant population falls by two-thirds in two years

(12/11/2008) Civil strife of Chad — a consequence of the calamity in Darfur — is taking a toll on the country's elephant population, reports the Wildlife Conservation Society (WCS) which has launched an emergency appeal for funds to support conservation efforts in the country.


Deal on forests falls short

(12/11/2008) A deal reached Wednesday in Poznan to include forests in future climate treaties is a positive step but falls short of the progress needed to get the REDD (reducing emissions from deforestation and degradation) mechanism on track for incorporation into the framework that will succeed the Kyoto Protocol, say environmentalists speaking from the talks.


Elephants die significantly earlier in zoos than in wild

(12/11/2008) A new study from Science provides disturbing evidence that one of the zoos’ most popular animals, the elephant, faces a far shorter lifespan in captivity than in the wild. The findings raise new ethical and scientific questions regarding the rightness of keeping elephants in captivity and the causes of their shorter life-spans.


Africa calls for "full-range" of bio-carbon as climate solution

(12/10/2008) A coalition of 26 African countries is calling for the inclusion of carbon credits generated through afforestation, reforestation, agroforestry, reduced soil tillage, and sustainable agricultural practices in future climate agreements.


Why do different species of bird lay different numbers of eggs?

(12/10/2008) Clutch size varies greatly between bird species. Researchers now have a better idea why. Analyzing data on clutch size, biology, and habitat for 5,290 species of birds, a team of biologists — Walter Jetz (UC San Diego), Cagan H. Sekercioglu (Stanford University), and Katrin Böhning-Gaese (Johannes Gutenberg-Universität) — developed a model to predict variations in the number of eggs a species lays. They found clutch sizes are consistently largest in cavity nesters and in species occupying seasonal environments. The findings add depth and complexity to previous research that has shown short-lived species — ones that face high predation or have low survival rates among offspring — tend to lay more eggs than longer-lived species, which invest more resources in raising their offspring.


What allows rainforests to grow so wildly?

(12/10/2008) Molybdenum, a rare trace element, is the secret to rainforests' lush growth, reports research published in the journal Nature Geoscience.


Tropical species face high extinction risk

(12/10/2008) Tropical plant species face an inherently high extinction risk due to small populations and restricted ranges relative to temperate species, reports research published in PLoS ONE. These traits leave them vulnerable to habitat disturbance and climate change.


Fear and conservation

(12/10/2008) How does fear shape the behavior and conservation of deer, moose and antelope, not to mention carnivores such as wolves, bears, and even tigers? What is the natural state of wildlife, and how do animals know or learn which species to ignore or fear? Should we reintroduce predators to former habitats, even though the prey animals may be unprepared for their return?


Indigenous people win voice in climate negotiations

(12/10/2008) Negotiators at U.N. climate conference have struck a deal to give forest-dependent people a voice in determining the role forest conservation will play future agreements to reduce greenhouse gas emissions, reports the Associated Press (AP). The agreement clears a key obstacle that had been blocking progress on reducing emissions from deforestation and degradation (REDD), a mechanism that would compensate tropical countries for protecting their forest cover.


Macedonians plant six million trees—in one day

(12/10/2008) While the world meets in Poznan, Poland to discuss actions related to global warming, the small Republic of Macedonia has already achieved an impressive goal. On November 19th, thousands of Macedonians took part in planting trees in a massive reforestation effort. Altogether they planted six million trees: three trees for every citizen of the country.


Finland, Sweden push for loophole that would drive destruction of peatlands around the world

(12/09/2008) Finland and Sweden are pushing for a loophole in the E.U.'s Renewable Energy Directive that would open up vast tracts of peatlands around the world to development for biofuels production. The move could have drastic consequences for climate and biodiversity, warns Wetlands International, an environmental group.


Wildlife banking gets a marketplace

(12/09/2008) Ecosystem Marketplace, a site that provides information on markets and payment schemes for ecosystem services, has launched what it is calling the "first information clearinghouse" for the species credit trading industry.


Drought and deforestation in southeast Asia linked to climate change

(12/09/2008) Researchers have linked drought and deforestation in southeast Asia to climate change. Analyzing six years of climate and fire data from satellites, Guido van der Werf and colleagues report that burning of rainforests and peatlands in Indonesia, Malaysia, and Papua New Guinea released an average of 128 million tons of carbon (470 million tons of carbon dioxide - CO2) per year between 2000 and 2006. Fire emissions showed highly variability during the period, but were greatest in dry years, such as those that occur during El Niño events. Borneo was the largest source of fire emissions during the period, averaging 74 million tons per year, followed by Sumatra, which showed a doubling in emissions between 2000 and 2006.


In Poznan, France pushes initiative to save rainforests

(12/08/2008) As talks for incorporating forest conservation into an international climate treaty stall in Poznan, Poland due to technical debates, France has proposed an aggressive effort to address deforestation and forest degradation through the establishment of a Global Forest Carbon Mechanism (GFCM) and potential inclusion of forestry projects in the E.U.'s emissions trading scheme (ETS) beginning in 2013.


Peru seeks $200 million to save its rainforests

(12/08/2008) Peru is seeking $200 million in international contributions over the next ten years to cut deforestation to zero, reports BBC News.


New standards ensure forest carbon projects protect indigenous people, biodiversity

(12/08/2008) The Climate, Community & Biodiversity Alliance (CCBA) has released its second edition of its CCB Standard for certifying land-based carbon offset projects.


Madagascar hit by deadly vanilla-killing fungus

(12/08/2008) Madagascar, the world's largest producer and exporter of vanilla, has been hit by a deadly, incurable fungus that can kill vanilla plants before their pods reach maturity, reports The Associated Press. The development could have dire impacts for the country's vanilla industry which generates hundreds of millions of dollars per year for the impoverished Indian Ocean island nation.


Little progress on avoided deforestation at climate meeting in Poland

(12/05/2008) Climate talks in Poland are failing to make progress on a proposed mechanism to reduce greenhouse gas emissions from deforestation, reports a forest policy group from the negotiations.


REDD faces challenges but can succeed, says report

(12/05/2008) The Center for International Forestry Research (CIFOR), a forest policy think tank, today released its assessment on the proposed REDD (reducing emissions from deforestation and degradation) mechanism for slowing climate change.


Saline agriculture may be the future of farming

(12/04/2008) Accessible and unpolluted freshwater is a necessity for every nation's stability and well-being. Yet, while the demand for freshwater continues to rise, its sources face increasing threats from salinization, a process whereby the salt content of fresh water rises until the water becomes undrinkable and unusable in agriculture: the more salt in the soil, the lower the crop yield.


Bank of America will no longer finance mountaintop removal coal mining

(12/04/2008) Bank of America will phase out financing for companies that practice mountaintop removal coal mining, a destructive and controversial method of coal extraction, according to a statement from the banking giant. The policy comes the day after the Environmental Protection Agency — at the behest of the Bush administration — approved a rule that will make it easier for coal companies to dump waste from mountaintop removal mining operations into streams and valleys.


WWF criticizes Brazil's plan to cut Amazon deforestation

(12/04/2008) WWF criticized Brazil's plan to reduce Amazon deforestation to 5,740 square kilometers per year as being "short on ambition and detail". In a statement issued Wednesday, WWF said that Brazil's proposed fund for conserving the Amazon would still result in the annual loss of an area forest the size of Rhode Island.


REDD may harm forest people, alleges report

(12/02/2008) A new report finds that the World Bank is not doing enough to protect indigenous rights under its mechanism to reduce emissions from deforestation and forest degradation (REDD).


Agricultural firms cut incentives for Amazon deforestation

(12/02/2008) As grain prices plummet and concerns over cash mount, agricultural giants are cutting loans to Brazilian farmers, reports the Wall Street Journal. Tighter farm credit may be contributing to a recent slowing in deforestation in the Brazilian Amazon, where agriculture is an increasingly important driver of forest clearing.


Niche-based distribution modeling may help improve effectiveness of protected areas

(12/01/2008) Niche-based distribution modeling may help researchers evaluate the effectiveness of protected areas, especially in regions lacking comprehensive databases of species distribution, reports a new analysis published in the December issue of Tropical Conservation Science.


Tropical dry forest fragments important to conserving reptile biodiversity in Colombia

(12/01/2008) An important task in tropical conservation is to understand which species are particularly vulnerable to extinction, and identify the characteristics that put them at risk. Because habitat loss and fragmentation are at the root of the global extinction crisis, an extensive collection of literature has developed around profiling species assemblages in fragmented landscapes. It is also clear that species may respond differently to fragmentation, but many species experience direct or indirect negative effects, sometimes resulting in local extirpation in habitat patches.


Lack of information may slow conservation response to amphibian crisis

(12/01/2008) The Neotropics harbor between 30-50% of the world's reptiles and amphibians, but dramatic declines in both groups have been observed over recent decades. While a number of factors have been cited, many of the causes of reptile and amphibian declines are still poorly understood. The situation is paralleled by a lack of information of the natural history, ecology, and behavior of many species.


The number of endangered amphibians in Peru may be underestimated

(12/01/2008) The number of threatened amphibian species in Peru may be significantly underestimated, increasing the risk that conservation decisions will fail to account for their needs, report researchers writing in the December issue of Tropical Conservation Science.


Manatees become conservation symbol for communities in Mexico

(12/01/2008) Local conservation efforts are helping protect endangered manatees in Chiapas, Mexico, report researchers writing in the December issue of Tropical Conservation Science.


Rural depopulation to have biodiversity impacts

(12/01/2008) Urbanization -- and accompanying rural abandonment -- may have profound implications for global biodiversity and therefore should factor into conservation planning, argue researchers writing in the December issue of Tropical Conservation Science.


Co-management of conservation areas offers multiple benefits

(12/01/2008) The Serengeti (Tanzania, East Africa)—one of the flagship conservation areas of the world—is the focus of a new paper published in the December issue of Tropical Conservation Science by Jafari R Kideghesho and Paul E Mtoni. The authors argue that conservation in the Serengeti needs to be approached as co-management involving sharing of power, responsibilities, and rights and duties between the government and local resource users. They advocate for intensive community involvement and reactivation of local traditional institutions in co-management approaches.


Rangers return to Virunga and begin gorilla census

(12/01/2008) After fifteen months rangers have been allowed to return to Virunga National Park in the Democratic Republic of Congo (DRC). A deal was worked out between insurgents and the government to allow rangers to return and begin overseeing the park's operations and monitoring its wildlife once again. Virunga is famous as one of the world's last stands for the mountain gorilla.


Brazil to cut Amazon deforestation by 70% to fight global warming

(12/01/2008) Brazil will aim to cut its deforestation rate by 70 percent by 2018 under its plan to reduce emissions from forest clearing, Environment Minister Carlos Minc.


Living up to the Pope's words: the Vatican turns to solar power

(11/28/2008) In his three years since being inaugurated, Pope Benedict XVI has made the environment one of his central issues, proclaiming that "God entrusted man with the responsibility of creation". He has described the need to confront climate change as a “moral obligation” and spoken eloquently on the destruction of arable soil, forests and marine life.
