Climate Linked to Atmospheric-River Storms
November 8, 2013 03:45 PM - Editor, ENN
It's not every day that the weatherman reports on atmospheric river storms...but we may be hearing the term more frequently now as researchers have linked climate in the Pacific Ocean and West Coast mountains to these distinctive storms. An atmospheric river is a narrow stream of wind, about a mile high and sometimes of hurricane strength. Crossing the warm tropical Pacific in a few days, it becomes laden with water vapor. A moderate-sized atmospheric river carries as much water as the Mississippi River dumps into the Gulf of Mexico in an average week! When the river comes ashore and stalls over higher terrain, the water falls as snow or rain.
Plan It for the Planet! November 15th America Recycles Day
November 8, 2013 10:16 AM - Robin Blackstone, ENN
So maybe America Recycles Day isn't as well known as Thanksgiving, New Years or the Fourth of July, but it is potentially becoming equally as significant for our planet's future! While our national recycling rate has increased each year for the past 30 years there is still great opportunity for recycling. America Recycles Day is the only nationally recognized day and community-driven awareness event dedicated to promoting and celebrating recycling in the U.S.
Relating the trees in the Amazon to west coast droughts
November 7, 2013 02:09 PM - Morgan Kelly, Princeton University
In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires.
Tesla in the Mass Market
November 7, 2013 08:42 AM - MoveForward, Electric Forum
Tesla Motors is a company, which seems to go from strength to strength and indeed to all intents and purposes this is a company, which has dragged the electric vehicle market kicking, and screaming to the point of mass acceptance. Anybody who has even looked at electric vehicles will be well aware that Tesla began life at the top end of the luxury car market and once this particular niche was dominated the company began to look further down the electric car food chain.
Ice Cores may yield 1.5 million year climate record
November 7, 2013 06:11 AM - ScienceDaily
How far into the past can ice-core records go? Scientists have now identified regions in Antarctica they say could store information about Earth's climate and greenhouse gases extending as far back as 1.5 million years, almost twice as old as the oldest ice core drilled to date. The results are published this week in Climate of the Past, an open-access journal of the European Geosciences Union (EGU). By studying the past climate, scientists can understand better how temperature responds to changes in greenhouse-gas concentrations in the atmosphere. This, in turn, allows them to make better predictions about how climate will change in the future.
Deep sea Drilling in New Zealand
November 6, 2013 01:51 PM - Rachel Shaw, The Ecologist
Deep sea drilling will soon commence in the rough waters off the New Zealand coast. This could mark the beginning of an oil rush in which democratic process, public concern, environmental protection and safety considerations are all swept aside. The Exclusive Economic Zone (EEZ) around New Zealand is fifteen times larger than the country's land area - it extends from the sub-tropical to the sub-Antarctic. Like the Arctic, New Zealand's EEZ supports a multitude of species which travel from far-flung areas of the globe to reach these rich waters. Like the Arctic, New Zealand's EEZ is fast becoming an oil exploration frontier.
Hotel Marketing Strategy: To Green or Not to Go Green
November 6, 2013 12:39 PM - Robin Blackstone, ENN
Over the last decade hotels and other businesses have increasingly adopted more and more green strategies as part of their daily operations. These strategies have transcended to marketing declarations of eco-certification that are then toted on hotel websites and other marketing materials for the consumer’s consideration when making their purchase decision. Researchers from Cornell’s School of Hotel Administration have studied the benefits of this certification to determine its effectiveness for capturing business. But does this matter to the consumer?
Deforestation may hurt US agriculture, affect monsoon cycle
November 6, 2013 08:58 AM - Rhett A. Butler, MONGABAY.COM
Unchecked deforestation will have far-reaching impacts on temperature, rainfall, and monsoon cycles in regions well outside the tropics, affecting agriculture and water availability, warns a new report published by Greenpeace International. The report, titled "An Impending Storm: Impacts of deforestation on weather patterns and agriculture", is a synthesis of dozens of recent scientific papers that assess the effects of forest cover loss on weather patterns, local climate, and agricultural productivity.
2013 PCB dredging on the Hudson
November 5, 2013 02:50 PM - Editor, ENN
The U.S. Environmental Protection Agency today announced that more than 612,000 cubic yards of river bottom sediment contaminated with PCBs were removed from the upper Hudson River during 2013, exceeding the annual goal of 350,000 cubic yards for this historic dredging project. This is similar to the amount dredged in 2012 when more than 650,000 cubic yards were removed. The Superfund cleanup required by the EPA calls for the dredging of approximately 2.65 million cubic yards of PCB-contaminated sediment from a 40-mile stretch of the upper Hudson River between Fort Edward and Troy, New York. The project began in 2009 and is about 73% complete, putting the dredging on track to be finished in two years. To date, about 1.9 million of the 2.65 million cubic yards million have been removed. Filling of previously dredged areas with clean sand and gravel will continue over the next several weeks, weather permitting. About 280 local area contractors, subcontractors, vendors and suppliers have provided goods or services related to Hudson River dredging.
Sea stars wasting away on both U.S. coasts
November 5, 2013 02:01 PM - Robin Blackstone, ENN
Evidence suggests that we are at the onset of another sea star wasting event. Sea stars on both the east and west coasts of the United States have fallen victim to a wasting disease that overcomes the Pisaster ochraceus in a matter of days once an initial lesion appears. The disease, while currently not understood, is rapidly transmitted amongst the population once it takes hold. On the west coast studies show that the disease is bacterial but on the east coast it is viral. Both result in a similar disintegration of the flesh within a very short period of time.
