That sinking feeling on the Mississippi Delta
April 21, 2014 09:49 AM - Robin Blackstone, ENN

Every engineering control has its drawbacks. As communities upstream of the Mississippi Delta continue to emplace dams and other flood control measures to prevent community flooding, less sediment is pulled from the lands upstream. Flood control measures have eliminated about half of the annual supply of marshland sediment to the Mississippi Delta. The existing soils continue to compact and sink without sediment replenishment. But researchers have found that the river’s supply of sand, the key ingredient used by engineers for rebuilding, will remain constant for many centuries.

Bacardi Makes Energy Efficiency Upgrades to Its Rum Facility in Puerto Rico
April 21, 2014 08:20 AM - Gina-Marie Cheeseman, Triple Pundit

Bacardi Ltd. is a world famous maker of rum, but the company is becoming known for something else: its sustainability measures. After highlighting significant reductions in water and energy use in its 2013 corporate social responsibility (CSR) report, Bacardi recently announced new energy efficiency measures. These measures include installing solar skylights, which increase natural light, and ceiling insulation, which helps control temperatures in the company’s warehouses where rum sits inside white oak barrels to process. The company is located in Puerto Rico, a "small Caribbean island with limited resources," as Julio Torruella, project director for Bacardi in Puerto Rico, said in a statement.

The Atlantic Cup looks to raise awareness on Rhode Island’s increasingly polluted shorelines
April 18, 2014 11:32 AM - Guest Contributor, Jeff Pomeroy

The 2014 Atlantic Cup presented by 11th Hour Racing, now entering its fourth year as the United States premiere class 40 yacht race, continues to lead the way in clean sailing and increasing ecologically awareness in the sailing community. In 2012, the Atlantic Cup became the first carbon-neutral sailing race in the country by offsetting an estimated 23,030 pounds (10.45 metric tons) of CO2 from entering the atmosphere. Last year, in partnership with 11th Hour Racing and Green Mountain Energy Company, the Atlantic Cup was chosen as the first event to meet all the requirements to earn Sailors for the Sea Clean Regatta Platinum Level Status. The Atlantic Cup will once again maintain its commitment to being the most environmentally responsible sailing race in the U.S. by using biodiesel hydro generators, solar panels and fuel cells to limit the use of fuel during competition, recycling waste, and becoming a plastic water bottle free event.

IPCC concludes: Renewable energy shift is a must
April 15, 2014 10:34 AM - ENN Editor

Conclusions from the Intergovernmental Panel on Climate Change's are simple: rapid shifts to renewable energy are needed to avert catastrophic global warming. The IPCC's report was produced by 1250 international experts and approved by each major government in the world. The report documented increases in human-caused greenhouse gases, the source of those gases, and their climatic effect. The most significant conclusions resulting from IPPC report are: - Current efforts to reduce greenhouse gases are not enough. - Energy supply is not the only thing driving emission increases. - Big changes will be needed to avoid disaster scenarios.

US EPA finds the most energy efficient buildings in top 10 cities
April 11, 2014 08:52 AM - US EPA Energy Star

Yesterday the U.S. Environmental Protection Agency (EPA) released its sixth annual list of the 25 U.S. metropolitan areas with the most ENERGY STAR certified buildings in 2013. The list demonstrates economic and environmental benefits achieved by facility owners and managers in America’s leading cities when they apply a proven approach to energy efficiency to their buildings.

LED Bulb Challenge ending soon!
April 9, 2014 01:34 PM - ENN Staff

The most inefficient light bulbs may now be off the market, in response to new federal standards, but nearly 70% of light bulb sockets in the U.S. still contain an inefficient bulb. Retailers across the country are stepping up to help change that, as part of the Energy Star LED Bulb Challenge.

At more than 23,000 feet, why don't bar-headed geese get hypoxic?
April 9, 2014 10:04 AM - ENN Staff

The bar-headed goose migratory path takes it over the Himalayan Mountains each year between China and Mongolia to their Indian breeding grounds. This flight path puts them at 23,917 feet above sea level. University of Exeter led study followed these birds to gain insight into their ability to survive these extreme altitudes in hopes that their findings might have future implications for low oxygen medical conditions in humans.

Filipino vulnerability
April 3, 2014 11:24 AM - By Esperanza Garcia, Worldwatch Institute

Climate change has been a constant reality for many Filipinos, with impacts ranging from extreme weather events to periodic droughts and food scarcity. The most affected populations are coastal residents and rural communities that lack proper disaster preparedness.

American's energy usage jumps in 2013
April 2, 2014 01:08 PM - ENN Staff

Despite many individual efforts to decrease energy usage for 2013 increased by 2.3 Quadrillion thermal units over the previous year. These statistics have been monitored and presented by the Lawrence Livermore National Laboratory (LLNL) in the most recent energy flow charts measuring renewable, fossil and even nuclear energy.

A sooner Spring and a later Autumn suggests the new normal
March 28, 2014 10:36 AM - University of Southampton newsroom

A study by the University of Southampton suggests that on average the end of Autumn is taking place later in the year and Spring is starting slightly earlier. A team of researchers examined satellite imagery covering the northern hemisphere over a 25-year period (1982 - 2006), and looked for any seasonal changes in vegetation by making a measure of its 'greenness'. They examined in detail, at daily intervals, the growth cycle of the vegetation — identifying physical changes such as leaf cover, color and growth.
