Impacts of Global Warming on Rainforest Modeled
March 11, 2013 05:58 AM - Rhett Butler, MONGABAY.COM
Tropical forests may be less sensitive to global warming than previously thought, argues a new study published in Nature Geoscience. The research is based on computer simulations using 22 climate models for tropical forests in Africa, Asia, and the Americas. It projects loss of forest biomass as a result of climate change only in the Americas. However the study is far from conclusive, with the authors listing several uncertainties about how tropical forests will respond to climate change.
Caribbean Nations Take Control of Their Collective Energy Future
March 8, 2013 01:24 PM - Katie Auth and Evan Musolino, Worldwatch Institute
In the face of the many challenges inherent in getting 15 countries—each with their own resources, priorities, and political complexities—to agree to anything, let alone a comprehensive regional energy policy, the Caribbean is now on the brink of taking a significant (and impressive) step forward. For the past half decade, a Draft Caribbean Community (CARICOM) Regional Energy Policy—designed to address critical issues like energy security, affordability, energy efficiency, and renewable energy—has been circulating among CARICOM's 15 member states, continually being revised to reflect the concerns of individual members, but never finalized.
In the News: USA and Russia unite to protect the polar bear
March 7, 2013 12:17 PM - Kaz Armour, ARKive.org
As the 16th meeting of the Conference of the Parties continues, the USA and Russia have come together in an attempt to ban export trade in polar bear products. In a bid to provide polar bears with the highest level of protection under the Convention on International Trade in Endangered Species (CITES), the American-Russian proposal calls for a ban on any international commercial trade of skin, fur, fangs and other products made from polar bears.
The Smart Grid and Electric Car Charging
March 7, 2013 06:20 AM - Roger Greenway, ENN
Widespread adoption of electric vehicles will reduce greenhouse gas emissions significantly. Some are worried that the electric grid will be stressed leading to a decrease in its reliability. In related news today, Battelle and AeroVironment have a technology that will address this concern, and help EV's charge when the grid is most able to support charging. This technology is the subject of a commercial license agreement between Battelle and AeroVironment, Inc., of Monrovia, Calif. The technology may also ultimately result in lower costs for plug-in electric vehicle owners. Battelle operates the Department of Energy's Pacific Northwest National Laboratory in Richland, Wash. AeroVironment will use a portion of the licensed technology in a new prototype version of its Level II charging systems.
International Year of Water Cooperation
March 6, 2013 06:15 AM - Jan Lee, Triple Pundit
As organizations around the world search for ways to ensure that impoverished communities have dependable access to drinking water, a new concern has surfaced: Just who will own the rights to managing that water access in the years to come? In 2010, in what seemed at the time to be an awesome example of prescience, the United Nations labeled 2013 the International Year of Water Cooperation (IYWC). Of course, the branding wasn't intended to recognize accomplishments the world has made in sharing its water resources, but to spur countries and communities around the globe to acknowledge that the potential for a global water crisis is real and that according to the UN, challenges such as "water diplomacy, transboundary water management, financing cooperation, national/international legal frameworks" need to be addressed.
National Climate Change Policy in Pakistan
March 5, 2013 06:26 AM - Faisal Raza Khan, SciDevNet
Pakistan's newly launched national climate change policy (NCCP) aims at natural resource conservation at home, but it also sees regional and bilateral agreements as key to ensuring water, food and energy security. The policy will be implemented by its provincial governments. At its launch last month (26 February), Pakistan's minister for climate change Rana Mohammad Farooq Saeed Khan said efforts would be made to strengthen provincial environment departments to enable them to carry out relevant functions devolved to them.
In the News: 100 million sharks killed each year by commercial fishing
March 4, 2013 02:51 PM - Katrina Armour, ARKive.org
Ahead of the 16th meeting of the Convention on the International Trade in Endangered Species that runs from the 3rd to the 15th of March this year, researchers are again warning that sharks are in need of better protection. A new report, published in the journal Marine Policy, estimates the annual number of sharks killed by commercial fishing to be around 100 million, although the actual number could be anywhere between 63 million and 273 million.
EU Hopes to Make Progress with Fishing Industry Reforms
March 4, 2013 09:22 AM - Christian Schwagerl, Yale Environment 360
Overfishing has been an important environmental issue recently as catching too many fish in one area can lead to food chain imbalances and the overall degradation of that system. Christian Schwagerl for YaleEnvironment360 discusses Europe’s over-subsidized fishing industry and what members of the European Union (EU) are doing to change and protect Europe’s marine environment.
Global Warming Being Slowed by Volcanic Eruptions
March 2, 2013 07:39 AM - Roger Greenway, ENN
Planet Earth did not warm as much in response to increases in green house gas emissions as expected. There appear to be other factors that influence global temperatures than green house gasses. A team led by the University of Colorado Boulder looking for clues about why Earth did not warm as much as scientists expected between 2000 and 2010 now thinks the culprits are hiding in plain sight -- dozens of volcanoes spewing sulfur dioxide. The study results essentially exonerate Asia, including India and China, two countries that are estimated to have increased their industrial sulfur dioxide emissions by about 60 percent from 2000 to 2010 through coal burning, said lead study author Ryan Neely, who led the research as part of his CU-Boulder doctoral thesis. Small amounts of sulfur dioxide emissions from Earth’s surface eventually rise 12 to 20 miles into the stratospheric aerosol layer of the atmosphere, where chemical reactions create sulfuric acid and water particles that reflect sunlight back to space, cooling the planet.
Democratic Republic of Congo’s Last Large Forest Elephant Population in Serious Decline
March 1, 2013 06:38 AM - Wildlife Conservation Society
The Democratic Republic of Congo's (DRC) largest remaining forest elephant population, located in the Okapi Faunal Reserve (OFR), has declined by 37 percent in the last five years, with only 1,700 elephants now remaining, according to wildlife surveys by WCS and DRC officials. WCS scientists warn that if poaching of forest elephants in DRC continues unabated, the species could be nearly extinguished from Africa's second largest country within ten years. According to the latest survey, 5,100, or 75 percent, of the reserve's elephants have been killed in the last 15 years. These numbers are particularly shocking as the OFR is considered the best protected conservation area in DRC. According to WCS, the primary reason for the recent decline in forest elephant numbers is ivory poaching.
