Black Bears return to Reno
March 29, 2013 06:21 AM - Wildlife Conservation Society
A new study from the Wildlife Conservation Society (WCS) and the Nevada Department of Wildlife ( NDOW) has pieced together the last 150 years of history for one of the state's most interesting denizens: the black bear. The study, which looked at everything from historic newspaper articles to more recent scientific studies, indicates that black bears in Nevada were once distributed throughout the state but subsequently vanished in the early 1900s. Today, the bear population is increasing and rapidly reoccupying its former range due in part to the conservation and management efforts of NDOW and WCS. Compelled in part by dramatic increases in human/bear conflicts and a 17-fold increase in bear mortalities due to collisions with vehicles reported between the early 1990s and mid- 2000s, WCS and NDOW began a 15-year study of black bears in Nevada that included a review of the animal’s little-known history in the state.
Egyptian Solar Power
March 27, 2013 04:55 PM - Andy Soos, ENN
Egypt is a land of ancient mysteries. It is a desert country with one long river flowing through it. Desert means lots of sun. Egypt is preparing to build a billion dollar solar power plant with help from a suite of international donors. Construction of Kuryamatt, a 150-megawatt hybrid power plant that will use both solar energy and natural gas to generate electricity, is underway 90 kilometers south of Cairo. Plans for a second large solar plant, in Upper Egypt's Kom Ombo, are also underway. These moves come after severe power cuts crippled the country last year during the hot summer months when Egyptians blast their air-conditioning units, and power up their stoves to prepare Ramadan feasts.
New Federal Handbook Guides Coordination of Environmental, Historic Preservation Review
March 27, 2013 08:26 AM - Jonathan Kalmuss-Katz, Sive Paget & Riesel, P.C.
Earlier this month, the Council on Environmental Quality ("CEQ") and the Advisory Council on Historic Preservation ("ACHP") published a new handbook governing the coordination of project review under the National Environmental Policy Act ("NEPA") and Section 106 of the National Historic Preservation Act ("Section 106"). Drawing from existing rules and guidance from both agencies, the Handbook for Integrating NEPA and Section 106 Reviews (the "Handbook") summarizes regulatory requirements; provides checklists and flow-charts to assist project sponsors and reviewing agencies; and emphasizes opportunities to synchronize and streamline review under both statutes.
Teach Your Children Well - About Climate Change
March 27, 2013 06:04 AM - JENNIFER LUDDEN, NPR
By the time today's K-12 students grow up, the challenges posed by climate change are expected to be severe and sweeping. Now, for the first time, new federal science standards due out this month will recommend that U.S. public school students learn about this climatic shift taking place. Mark McCaffrey of the National Center for Science Education says the lessons will fill a big gap. "Only 1 in 5 [students] feel like they've got a good handle on climate change from what they've learned in school," he says, adding that surveys show two-thirds of students say they're not learning much at all about it. "So the state of climate change education in the U.S. is abysmal."
EPA Fracking Panel
March 26, 2013 03:52 PM - Andy Soos, ENN
Hydraulic fracturing is the propagation of fractures in a rock layer by a pressurized fluid. Some hydraulic fractures form naturally—certain veins or dikes are examples—and can create conduits along which gas and petroleum from source rocks may migrate to reservoir rocks. Induced hydraulic fracturing, commonly known as fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas, and coal seam gas), or other substances for extraction. The U.S. Environmental Protection Agency’s (EPA’s) independent Science Advisory Board (SAB) today announced the formation of its Hydraulic Fracturing Research Advisory panel. This panel of independent experts will peer review EPA’s 2014 draft report of results for its national study on any potential impacts of hydraulic fracturing on drinking water resources. The SAB panel will provide scientific feedback on EPA’s research in an open and transparent manner on this controversial subject. The development of the draft report, which is directed by Congress, is in line with the Administration’s focus on continuing to expand safe and responsible domestic oil and gas production.
Majority of US Streams and Rivers are in 'Poor Condition,' says EPA Survey
March 26, 2013 12:32 PM - Allison Winter, ENN
The U.S. Environmental Protection Agency (EPA) has just released the results of a comprehensive survey that looks at the health of thousands of stream and river miles across the country, and frankly the results are not very encouraging. The survey was conducted as part of an ongoing effort by the EPA to determine which rivers and streams are healthy, which are improving, and which require more protection and restoration efforts.
Man Caught Smuggling Over 10% of Tortoise Species' Population
March 25, 2013 12:14 PM - Jeremy Hance, MONGABAY.COM
On Friday, March 15th Thai authorities arrested a 38-year-old man attempting to collect a bag containing 54 ploughshare tortoises (Astrochelys yniphora) and 21 radiated tortoises (Astrochelys radiata) in Suvarnabhumi International Airport. Found only in Madagascar both species are listed as Critically Endangered and protected under the Convention on International Trade in Endangered Species (CITES), but have become lucrative targets for the black-market pet trade given their scarcity and beauty.
Earth Hour 2013 Inspires Many Around the World
March 24, 2013 06:13 AM - WWF
WWF's Earth Hour has just concluded another record sweep around our planet from Samoa on one side of the International Date Line to the Cook Islands on the other, with hundreds of millions again uniting to send a clear message - we are determined to create a sustainable future for our planet. The event was observed in more than 7000 cities, towns and municipalities in more than 150 countries and territories, with many of the world's best known human and natural landmarks going dark as the backdrop to a multitude of "beyond the hour" activities and initiatives generating outcomes for the movement and the planet on which we live. "What is most important is the ever increasing extent to which Earth Hour's supporters are participating in or taking actions themselves," said Earth Hour CEO and Co-Founder, Andy Ridley.
Dams and Levees
March 22, 2013 03:26 PM - Andy Soos, ENN
Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The average age of the 84,000 dams in the US is 52 years old. The nation’s dams are aging and the number of high-hazard dams is on the rise. Many of these dams were built as low-hazard dams protecting undeveloped agricultural land. The average age of the 84,000 dams in the country is 52 years old. The nation’s dams are aging and the number of high-hazard dams is on the rise. Many of these dams were built as low-hazard dams protecting undeveloped agricultural land. Both are in sad shape and rated a D for dams and a D- for levees by the American Society of Civil Engineers who are the engineers who build them. If they go, homes and vast stretches of land will be flooded and the environment literally drenched.
The Importance of Aircraft Emission in Climate Change
March 21, 2013 06:50 AM - EarthTalk, Global Warming is Real
While air travel today accounts for just three percent of worldwide greenhouse gas emissions, the carbon dioxide (CO2) and other pollutants that come out of jet exhaust contribute disproportionately to increasing surface temperatures below because the warming effect is amplified in the upper atmosphere. The Intergovernmental Panel on Climate Change (IPCC), a scientific intergovernmental body set up by the United Nations (UN) to provide comprehensive scientific assessments of the risk of human-induced climate change, reports that CO2 emitted by jets can survive in the atmosphere for upwards of 100 years, and that its combination with other gas and particulate emissions could have double or four times the warming effect as CO2 emissions alone.Modern jet engines are not that different from automobile engines—both involve internal combustion and burn fossil fuels. But instead of gasoline or diesel, jet fuel is primarily kerosene, a common home heating fuel used around the world. Just like car engines, jets emit CO2, nitrogen oxides, sulfur oxides and soot.
