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.
Big Ben May Get a Solar Face Lift
March 13, 2014 08:04 AM - Sara Lozanova, Triple Pundit
In an effort by the U.K. Parliament to reach the ambitious goal of reducing greenhouse gas emission by 34 percent by 2020, the House of Commons is now looking to the parliamentary estate and considering installing solar panels on the face of Big Ben in London. Parliamentary passholders were submitting ideas for reducing carbon emissions and boosting energy efficiency on the estate, when the solar idea was suggested.
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."
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.
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.
COLLEGIATE CORNER: Trash talk: Ocean Dumping
March 10, 2014 11:01 AM - McKaylee Reavis, Class of 2015, Wakefield High School, Arlington, VA
Remember the excitement that filled your body when your parents told you the family was going to go to the beach? Remember the excitement slowly leaving your body when you witnessed the trash that covered the beach for miles? Ocean dumping has become a major problem for marine life and the people who enjoy its many benefits. Many marine animals have suffered from the trash in the water and people have suffered from the sight of trash filling the ocean and cluttering the beaches ruining their supposed beautiful day. Industries, cities, and militaries have been dumping their waste into the ocean for years now. One solution to prevent this problem is to impose stricter restrictions on ocean dumping that range from pedestrian waste to toxic nuclear hazard.
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.
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.
