A sooner Spring and a later Autumn suggests the new normal
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 â€“ identifying physical changes such as leaf... >> Read the Full Article
Air pollution, now the worldâ€™s single largest environmental risk
The World Health Organization today released mortality data from 2012 estimating that around 7 million people (one person in eight) died globally that year as a result of air pollution exposure. This finding more than doubles previous estimates and confirms that air pollution is now the worldâ€™s largest single environmental health risk. >> Read the Full Article
COLLEGIATE CORNER: Humanity of factory farming
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. >> Read the Full Article
EPA and Army Corps bring clarity to Clean Water Act Expansion proposal
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... >> Read the Full Article
Future cost of water is no small change
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... >> Read the Full Article
Worldâ€™s river systems: Stressed OUT
According to the World Resources Institute (WRI) many, if not most of the worldâ€™s rivers are stressed. Determining a systems water stress is based upon measuring the ratio of total water withdrawals to the available renewable supplies within the catchment area. Rivers are an indispensible resource for our communities and ecosystems and we are hugely dependent upon them for agriculture, industry and our natural systems. A stressed river system can severely threaten regional water security and... >> Read the Full Article
Road to environmental destruction
Roads are considered connectors of human development providing opportunities for economic success and communication but the flip side of this network is that it has also brought enormous destruction to our fields and forests. With forest destruction comes increased human development and ecological degradation. Recent mapping and modeling has been done to document and measure forest destruction in an initiative by the Ames Research Center of NASA and ENN affiliate, Mongabay. >> Read the Full Article
Fix-a-Leak Week
According to WaterSense, an Environmental Protection Agency Partnership Program, household leaks waste more than a trillion gallons of water annually. Our urgency to conserve often depends upon what part of the country we live. But officials predict that at least 36 states that will experience some sort of water shortage. >> Read the Full Article
COLLEGIATE CORNER: Offshore oil drilling: is it really necessary?
As we all know, oil is a very important energy resource the world needs for its everyday life. It is known that not only do most of the countries on the planet use it, but also it is a scarce resource, which means that in the near future, there will no longer be enough available oil that could be drilled and processed for future endeavors. The demand for oil has increased significantly throughout the past few years and other ways of obtaining this resource must be used more often. A form of... >> Read the Full Article
An insulation trifecta
A savvy do-it-yourselfer can come up with a dozen unconventional uses for insulation (spray foam as packing material, anyone?), which makes it tricky to find basic information online when you're just dipping your toes in to the DIY pool. Here is an introduction to the three basic types of insulation and their most common uses: blown-in, spray foam and batt/blanket insulation. >> Read the Full Article
