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

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.
COLLEGIATE CORNER: The faults of fracking
March 3, 2014 11:41 AM - Reid Short, Class of 2015, Wakefield High School, Arlington, VA
Hydraulic Fracturing is a process that sends pressurized liquid down to a target depth to fracture rock and draws out liquids, such as natural gas. This process is used to retrieve the gas from rock formations beneath the earth that were previously thought to be unsuitable for gas production (Helman) (Rao). Fracking is now being implemented all over the world. Many countries have turned to this method of extracting gas to lower fuel costs and balance their trade deficits, but these countries, including the United States, are allowing fracking to cause major damage to the environment. The water pollution, and air pollution that are caused by fracking, and the law exemptions it has, are inexcusable because of the damage and danger they cause to the environment.
Doubling the flood loss projections in Europe
March 3, 2014 10:36 AM - ENN Staff
As development and climate change continue, losses from extreme floods throughout the world skyrocket. Researchers from the International Institute for Applied Systems Analysis (IIASA), in Austria have projected that the losses in Europe could more than double by 2050. In the new study which is published in the journal Nature Climate Change, they contend that understanding the risk posed by large-scale floods is of growing importance and will be key for managing climate adaptation.
Noise Levels Can Affect Fish Behaviors
March 3, 2014 10:02 AM - University of Bristol
Fish exposed to increased noise levels consume less food and show more stress-related behavior, according to new research from the University of Bristol and the University of Exeter. However, the way fish decreased their food intake differed between the two British species tested. When exposed to noise, three-spined sticklebacks made more foraging errors whereas European minnows tended to socially interact more often with their companion fish or to reduce activity.
And the spotted seal said, "Say whaaaat?"
February 28, 2014 03:26 PM - Tim Stephens, University of California – Santa Cruz
Two spotted seals orphaned as pups in the Arctic are now thriving at UC Santa Cruz's Long Marine Laboratory, giving scientists a rare opportunity to learn about how these seals perceive their environment. In a comprehensive study of the hearing abilities of spotted seals, UCSC researchers found that the seals have remarkably sensitive hearing in both air and water.
Melting summer ice in Antarctica
February 28, 2014 01:53 PM - , ClickGreen
Antarctica's Ross Sea is one of the few Polar Regions where summer sea-ice coverage has increased during the last few decades, bucking a global trend of drastic declines in summer sea ice across the Arctic Ocean and in two adjacent embayments of the Southern Ocean around Antarctica. But now, a modeling study led by Professor Walker Smith of the Virginia Institute of Marine Science suggests that the Ross Sea's recent observed increase in summer sea-ice cover is likely short-lived, with the area projected to lose more than half its summer sea ice by 2050 and more than three quarters by 2100.
Illegal logging threatens sustainability in Mozambique
February 28, 2014 10:20 AM - , MONGABAY.COM
Illegal logging has spiked over the past five years in Mozambique, finds a new report by researchers at the University of Eduardo Mondlane. The report, published on the U.N. Food and Agriculture Organization's web site, assesses timber production, consumption, and exports, finding that nearly two-thirds of logging is currently illegal. The report notes that harvesting is exceeding sustainable levels, threatening the long-term viability of the industry and putting local livelihoods at risk.
