The Montana Supreme Court has ruled that bison can roam outside the park boundaries for winter and early spring forage without being shot. In 2008, more than 1,400 bison - about one-third of the current size of Yellowstone's bison population - were captured and slaughtered by government agencies while leaving Yellowstone in search of food. The Montana Supreme Court affirmed the decision of a lower court this week, allowing wild bison room to roam outside the northern boundary of Yellowstone National Park.
A global climate change directive?
March 14, 2014 04:11 PM - Editor, ENN
Could another climate change deal be in the works? World leaders are meeting in Brussels this month to discuss climate change. While environmentalists are calling for urgent action to cut greenhouse gas emissions, diplomatic language presented in the introductory document is most likely not ambitious enough.
Making the United States "anti-car"
March 14, 2014 02:33 PM - S.E. Smith, Care2
Visit Amsterdam, which feels like the bicycle capital of the world, and you'll see everyone on bikes, from chic ladies on their way to coffeehouses (a longstanding tradition in this European city) to office workers. The city offers dedicated bicycle paths, ample bike parking and lots more options to encourage people to cycle and it create active disincentives for driving. It's a decision born of practical and environmental concerns: Amsterdam is a small, easily crowded city, where cars could become a serious hazard and frustration if they multiplied on the streets, and its residents are very eco-conscious.
Antarctic ecosystem due to change radically with climate change
March 13, 2014 02:07 PM - Staff, ENN
According to researchers the Ross Sea will "be extensively modified by future climate change" in the coming decades creating longer periods of ice-free open water and affecting life cycles of all components of the ecosystem in a paper published and funded by the National Science Foundation (NSF). The researchers have drawn their information from the Regional Ocean Modeling System, a computer model that evaluates sea-ice, ocean, atmosphere and sea-shelf.
Rooftop considerations amidst climate change
March 13, 2014 11:54 AM - Robin Blackstone, ENN
As the realities of climate change set in, so too are realizations that building technologies impact both internal and external environments. The percentage increase of asphalt and blacktopped roofs create urban heat islands. Resultantly cities have become earth's newest desserts exhibiting high temperatures and arid conditions with little vegetation. Urban expansion as a stand-alone factor (omitting greenhouse gas-induced climate change considerations) is expected to raise temperatures by roughly six degrees. Because of this, scientists are now exploring new technologies to cope with the new reality.
Sustainable urban lawns
March 12, 2014 01:16 PM - robin Blackstone, ENN
Concern for the homogenization of America's urban landscape prompted a recent research study into the care and maintenance of residential landscapes. The study demonstrated fewer similarities than expected but the concern, according to researchers is that "Lawns not only cover a larger extent [of land] than any other irrigated 'crop' in the U.S., but are expected to expand in coming decades. The researchers go on to point out that the potential homogenization of residential lawn care has emerged as a major concern for carbon, nitrogen, phosphorus and water flows."
Is There a Sustainable Big Mac in Your Future?
March 12, 2014 07:58 AM - RP Siegel, Triple Pundit
Giant corporations like McDonald's and Walmart cast a long shadow across the planet with the enormous amount of resources that they use, process, consume and sell. McDonald's flips and bags 70 million hamburgers every day and is responsible for a full 2 percent of the world's beef consumption. So when you consider the impact that beef production has on the environment, particularly with regard to climate change, a move by them to sustainable beef could be a really big deal.
Feral cats a growing health concern
March 11, 2014 04:17 PM - Editor, ENN
A coalition of more than 200 groups which include various bird and wildlife conservation organizations and animal rights groups are calling on Secretary Sally Jewell of the Department of Interior to take action to reduce mortality to wildlife populations on public lands stemming from the nation's ever-increasing population of feral cats. The group brings evidence from the Centers for Disease Control and Prevention (CDC) that feral cats pose a threat to human health as a result of an exposure to rabies and toxoplasmosis, a parasitic disease affecting the human brain when exposed to cat feces.
Renewable energy helps Scotland become one of the world's wealthiest nations
March 11, 2014 03:32 PM - ClickGreen Staff, ClickGreen
Scotland’s control over a quarter of Europe’s offshore wind and marine energy has helped it become one of the world’s wealthiest nations, according to new analysis released today. The new figures from the Scottish Government show that Scotland with its broad base of economic strengths would be ranked as the 14th wealthiest nation per head within the OECD, the grouping of the world’s richest countries.
Many small glaciers make up the whole in Greenland
March 11, 2014 09:59 AM - George Hale, NASA
Research using NASA data is giving new insight into one of the processes causing Greenland's ice sheet to lose mass. A team of scientists used satellite observations and ice thickness measurements gathered by NASA's Operation IceBridge to calculate the rate at which ice flows through Greenland's glaciers into the ocean. The findings of this research give a clearer picture of how glacier flow affects the Greenland Ice Sheet and shows that this dynamic process is dominated by a small number of glaciers.
