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.

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.
COLLEGIATE CORNER: Humanity of factory farming
March 25, 2014 02:01 PM - Jake Bucks, Class of 2015, Wakefield High School
Most omnivores like bacon, but I say omnivores because not every human is an omnivore. Have you ever thought to yourself what was the process this bacon went through? Well if you have, it was not a fun process for that pig. Farming has helped humans advance in size, without the farming innovations created through the industrial revolution, humans would have never had the resources to make such a huge population.
EPA and Army Corps bring clarity to Clean Water Act Expansion proposal
March 25, 2014 01:38 PM - ENN Staff
In a joint document the EPA and the Army Corps of Engineers released a proposed rule to clarify protections provided by the Clean Water Act. Following Supreme Court decisions in 2001 and 2006, there has been much confusion about definitions within the Act and applicability. The proposed clarifications will enhance understanding for industry, agriculture, local government officials and the public as it relates to protection of streams and wetlands that form the foundation of the nation's water resources.
Future cost of water is no small change
March 25, 2014 12:22 PM - Dr. Lynn A. Wilson, Kaplan University
Water scarcity was, until recently, considered by most of the developed world to be like James Hilton's Lost Horizon: "far away, at the very limit of distance." However, the convergence of aquifer depletion from increasing agricultural, industrial and municipal water use with more frequent and intense extreme weather events creates an urgency to develop new, reliable sources of fresh water to "drought-proof" communities through a combination of desalinization technologies, water recovery and reuse programs and PPP (public private partnerships). The race is on to provide fresh water to satisfy ever-increasing human demands. In order to make responsible decisions, changing conditions require rethinking water policy and distribution.
