Fish and Wildlife Service Urged to Speed Protection for Bat
Published Aug 28, 2014 - 8:17:41 AM
Two dozen conservation and animal-welfare groups sent a letter today urging the U.S. Fish and Wildlife Service to complete its plan to protect the northern long-eared bat, a species found primarily in the eastern and midwestern United States. Opposition to the bat's protection under the Endangered Species Act — from timber, mining and energy industries as well as several state natural-resource agency officials — prompted the Fish and Wildlife Service to postpone a final decision on protecting the bat until spring 2015.

NOAA’s Marine Debris Program reports on the national issue of derelict fishing traps
Published Aug 27, 2014 - 10:01:57 AM
Thousands of fishing traps are lost or abandoned each year in U.S. waters and become what are known as derelict traps, which continue to catch fish, crabs, and other species such as turtles. These traps result in losses to habitat, fisheries, and the watermen who depend on the resources -- losses that are largely preventable, according to a newly published NOAA study.
World's Largest Plastic Bottle Structure Draws Attention to Global Plastic Pollution Crisis
Published Aug 25, 2014 - 8:35:54 AM
After a flood created a dam where one could cross the Nera River by stepping on plastic bottles at the point of Danube where it enters Romania, the cu.podu project was born, explained Radu Rusu of EcoStuff. The goal of the project is to do something big enough to draw attention to the enormous quantities of litter dumped every day in the rivers and oceans around the world, like other organizations are doing including 5 Gyres Institute, which just finished a three-week sail from Bermuda to Iceland and found microplastic particles in every surface sample collected during the trip.

Global warming is moistening the atmosphere
Published Aug 18, 2014 - 8:24:46 AM
We have long suspected that greenhouse gases which cause the Earth to warm would lead to a wetter atmosphere. The latest research published by Eul-Seok Chung, Brian Soden, and colleagues provides new insight into what was thought to be an old problem. In doing so, they experimentally verified what climate models have been predicting. The models got it right… again.
Human Contribution to Glacier Mass Loss on the Increase
Published Aug 15, 2014 - 8:20:19 AM
By combining climate and glacier models, scientists headed by Ben Marzeion from the University of Innsbruck have found unambiguous evidence for anthropogenic glacier mass loss in recent decades. In a paper published in Science, the researchers report that about one quarter of the global glacier mass loss during the period of 1851 to 2010 is attributable to anthropogenic causes. The fraction of human contribution increased steadily and accelerated to almost two thirds between 1991 and 2010.
How Much Is Nature Worth
Published Aug 13, 2014 - 11:05:45 AM
Ecosystem services – clean water, clean air, temperature regulation, food production, etc. – are the myriad ways in which people benefit from nature. Environmental economics is a growing field that, in part, tries to put a price tag on how much nature benefits people. The hope is that policy-makers and businesses will be more likely to preserve nature if they understand its importance.

Study: All penguin species at continuing risk from habitat degradation
Published Aug 6, 2014 - 12:20:41 PM
A major study of all penguin species suggests the birds are at continuing risk from habitat degradation. Writing in the journal, Conservation Biology, a group of internationally renowned scientists recommends the adoption of measures to mitigate against a range of effects including; food scarcity (where fisheries compete for the same resources), being caught in fishing nets, oil pollution and climate change. This could include the establishment of marine protected areas, although the authors acknowledge this might not always be practical. A number of other ecologically based management methods could also be implemented.
Proposed Rosemont Mine Threatens Rare Jaguar, Ocelot and Tucson's Water Supply
Published Aug 6, 2014 - 12:11:08 PM
The Center for Biological Diversity sent a letter today urging the U.S. Fish and Wildlife Service to again take an in-depth look at how the proposed Rosemont copper mine in southern Arizona will affect endangered species, including jaguars, ocelots and rare fish. Agency scientists, in earlier drafts of their "biological opinion" of the project, concluded the mine would not be compatible with endangered animals in the area, including the only jaguar known to be living in the United States. That conclusion was later reversed by a supervisor. The Service, though, announced earlier this year it would revisit that opinion in the face of new information.
Hawaii Farmers, Environmental Groups Defend Moratorium of GMO Crops
Published Aug 4, 2014 - 12:37:10 PM
A coalition of local farmers and environmental groups last week filed a motion to intervene in a lawsuit to defend a Hawai'i County ordinance that imposes a moratorium on the expansion of genetically engineered (GE) crops on the Big Island. On Aug. 1, Center for Food Safety (CFS), and three Hawai'i Island farmers asked the court permission to join as defendants in a biotech industry lawsuit challenging the County of Hawai'i's Ordinance 13-121. The ordinance regulates GE organisms to prevent their environmental and economic harms, such as contamination of organic and conventional crops and wild plants and associated pesticide use. The coalition is jointly represented by counsel from CFS and Earthjustice.

The Center for Biological Diversity filed a legal petition today urging the U.S. Environmental Protection Agency to protect people, wildlife and the environment from toxic and carcinogenic chemicals found in polyvinyl chloride (PVC), the same material once common in household plumbing. If successful, the petition will require that PVC be classified as hazardous waste, resulting in better regulations for disposal and, ultimately, a reduction in the amount of plastic trash and toxic chemicals additives contaminating communities across the country and polluting oceans worldwide.
Study gives new perspective on agricultural plastic, debris burning, and air quality
Published Jul 24, 2014 - 9:05:41 AM
To reduce fire hazard in the United States, wildland managers often utilize the silvicultural practice of mechanically cutting woody shrubs and suppressed trees (ladder fuels). These cuttings and other post-logging debris are then burned during periods of low fire danger in order to dispose of the material. To improve the burning and minimize hazardous air pollutants, managers often cover all or part of the debris pile with low-density polyethylene plastic, commonly referred to as agricultural plastic, in order to keep water out. A recent study published in the Journal of the Air and Water Association shows that inclusion of agricultural plastic in debris piles has no effect on smoke emissions.
Genetic study shows major impact of climate change on Antarctic fur seals
Published Jul 24, 2014 - 8:48:18 AM
Genetic analysis of Antarctic fur seals, alongside decades of in-depth monitoring, has provided unique insights into the effect of climate change on a population of top-predators. Published in Nature this week, the findings show that the seals have significantly altered in accordance with changes in food availability that are associated with climate conditions. Despite a shift in the population towards 'fitter' individuals, this fitness is not passing down through generations, leaving the population in decline.
