Warming up all over, even in the Arctic
March 10, 2014 09:55 AM - Tim Radford, Ecologist
It's long been established that Arctic Ocean sea ice is on the retreat, writes Tim Radford. But it's the pace of change that's surprising scientists: latest studies show that the ice-free period is increasing by 5 days / decade. Ice in the Arctic continues to retreat. The season without ice is getting longer by an average of five days every 10 years.
Protecting species in Canada
March 10, 2014 09:24 AM - Dr. David Suzuki, Care2
Of 345 species at risk in Canada, more than 160 have waited far too long for recovery strategies. Thanks to a recent federal court decision, four luckier ones are finally getting overdue plans detailing steps needed to save and protect them, including identifying habitat they need to survive. But to make it happen, environmental groups including the David Suzuki Foundation, with the help of Ecojustice lawyers, had to take the federal government to court. It wasn't the first time we’ve gone to court to protect wildlife.
Study Reveals Deer Slow Down Forest Progression
March 10, 2014 06:07 AM - Editor, ENN
Uncontrolled deer populations in rural and suburban areas have become a nuisance for many communities. Not only do deer cause damage to ornamental plants and private residential landscapes, but a new study confirms that deer populations are also altering forest progression. A team of researchers at Cornell University report that deer can create environmental havoc in forests by disrupting the natural soils and seed banks thus causing additional problems for the forest ecosystem.
Challenges and a call for Conservation Cooperation in the Arab world
March 8, 2014 08:31 AM - Mark Henley, SciDevNet
The Arab region's best chance of facing the challenges of food insecurity, water scarcity and natural disasters lies in collaborating on environmental preservation, a study says. The study, published in The Lancet (20 January), argues that current academic discussions about health, population and development in the Arab region fail to convey the true level of urgency.
Clear through the haze for marine ecosystems in Southeast Asia
March 7, 2014 11:51 AM - Kimberly Wang, National University of Singapore
The unprecedented high levels of transboundary haze in Southeast Asia last year prompted Dr. Zeehan Jaafar, a lecturer at the Department of Biological Sciences at the National University of Singapore Faculty of Science, and Dr. Tse-Lynn Loh, a postdoctoral research associate at the Daniel P. Haerther Center for Conservation and Research, John G. Shedd Aquarium (Chicago, USA), to critically evaluate the potential impacts of biomass burning and haze to marine ecosystems in the Southeast Asian region.
Arctic sea ice melting one warm river at a time
March 7, 2014 09:32 AM - Maria-Jose Vinas, NASA Earth Science News Team
A new NASA study finds that warmer than normal waters from rivers draining into the Arctic Ocean each summer are eating away at the sea ice in the Arctic Ocean. Led by Son Nghiem of NASA's Jet Propulsion Laboratory in Pasadena, Calif., the research team used satellite data to measure the surface temperature of the waters discharging from Canada's McKenzie River into the Beaufort Sea during the summer of 2012 and noticed surface waters being warmed suddenly due to the sudden influx of warm river water This warmed the surface layers of the ocean, which in turn increased the melting of sea ice.
Crop Pests "Vastly Underestmated' Warns Study
March 6, 2014 03:22 PM - Sci Dev Net Contibutor, SciDevNet
The number of different pests plaguing crops in the developing world may be vastly underestimated, contributing to severely reduced harvests in some of the world’s most important food-producing nations, say researchers.
Clean Water Act protects Bristol Bay
March 5, 2014 10:03 AM - Jessie Thomas-Blake, American Rivers
The Environmental Protection Agency (EPA) announced last week that it is initiating a process under the Clean Water Act (CWA) to identify appropriate options to protect the world's largest sockeye salmon fishery in Bristol Bay, Alaska, from the potentially destructive impacts of the proposed Pebble Mine!
Good news for Nepal's wildlife after another year of no poaching
March 5, 2014 08:05 AM - Hannah Mulvany, ARKive.org
After Nepal making a commitment to protect the future of its magnificent and highly endangered species, it has once again succeeded and between February 2013 and February 2014, no rhino, tigers or elephants were poached in the country. Nepal has a history of success in the prevention of poaching, and another poaching-free year occurred in 2011.
EPA Sets Cleaner Fuel and Car Standards
March 4, 2014 09:20 AM - ENN Staff
Yesterday the U.S. Environmental Protection Agency (EPA) finalized emission standards for cars and gasoline that will significantly reduce harmful pollution and in turn prevent thousands of premature deaths and illnesses related to respiratory ailments. Based on extensive input from the public and a broad range of stakeholders, including public health groups, auto manufacturers, refiners, and states, the standards will also enable efficiency improvements in the cars and trucks we drive.
