Thinning out on Antarctica
January 3, 2014 09:57 AM - ENN Editor
Pine Island Glacier, located in West Antarctica, is showing signs of thinning making it more susceptible to climatic and ocean variability than at first thought. Scientists led by the British Antarctic Survey have discovered large fluctuations in the ocean heat manifesting itself in the melting of the ice shelf into which the glacier flows. Between 2010 and 2012 the ice shelf into which the ice stream flows has decreased by 50%, most likely due to La Ninã, suggesting a complex interplay between geological, oceanographic and climatic processes.
Forecasting storms using lightning!

An alternative to costly radar-based weather services could soon be operational in developing nations, to help them detect severe storms more cheaply and quickly. The technology, which uses lightning detection to forecast when and where storms will strike, has already proven successful in demonstration projects in Brazil, Guinea and India. Next year, Earth Networks — one of the companies at the forefront of the technology — will conduct further trials in Haiti. As more developing nations increase their numbers of mobile phone masts, which are ideal locations for mounting the lightning sensors on, the proportion of countries using the technology looks set to increase, according to the US company.
2014 National Defense Authorization Act is huge win for LEED green building system

President Obama signed the National Defense Authorization Act for fiscal 2014 in Honolulu last Thursday and while most observers noted that the bill cracks down on sexual assaults in the military and eases restrictions on transferring detainees from Guantanamo Bay, the bill also is a huge win for the U.S. Green Building Council's LEED green building rating system. By way of background, the Air Force, Army, Marines, Navy and other instruments of the Department of Defense own and operate 299,000 buildings and 211,000 additional structures, making it the largest owner of buildings in North America, but it is also the owner of more green buildings and more LEED certified buildings than anyone else.
Catching Weevils with Different Colored Traps
January 3, 2014 08:15 AM - ENN Staff
The weevil is a type of beetle that is known for damaging crops. Whether they damage stored grain or dried food products, or attack cotton crops, the many types of weevils can cause problems for farmers and consumers alike. In an effort to develop more eco-friendly control methods for the weevil, researches have discovered that different colored traps attract more sweet potato weevils than other colors.
COLLEGIATE CORNER: Saving Earth from Space
January 2, 2014 12:41 PM - Destiny Allen; Environment, Economics, Development, Sustainability (EEDS), Class of 2015, The Ohio State University
When we think of the environment, we do not immediately jump to thinking of outer space. The environment usually conjures up images on Earth of breathless beauty, but this does not mean a solution to renewable energy is bound to the limits of our planet.
Save your holiday greens to help the birds!
January 1, 2014 09:50 AM - Alicia Graef, Care2
As bitter winter winds blow through the leafless trees and forest birds search for the shelter of an evergreen, we can offer them some help by repurposing our leftover holiday greenery. With the loss of woodlands, backyard habitats have become increasingly important for birds that stay with us through the winter months. Cornell University’s Lab of Ornithology just published a friendly reminder that we can extend the usefulness of our holiday trees, wreaths and other greenery by putting them near feeders and in yards, among other things, to offer birds thermal refuge, instead of just tossing them to the curb.
Coping in a harsh desert environment

Far from being devoid of life, deserts are home to numerous plants and animals. In the desert, plants and animals often compete for limited resources: especially water. To cope, plants will adopt different strategies to compete with their neighbors for this precious resource.
Impacts of climate change in the deep sea
December 31, 2013 12:30 PM - Robin Blackstone, ENN
Even the most remote deep-sea ecosystems are affected by climate change according to a study conducted by the National Oceanography Centre at the University of Southampton, UK. According to the study, seafloor dwellers will decline by up to 38% in the North Atlantic and over 5% globally over the next century because of a reduction in the ocean's surface plants and animals.
Water year round in the land of ice
December 30, 2013 10:00 AM - Robin Blackstone, ENN
In Greenland where three quarters of the land mass is covered by the earth's only inhabited ice sheet, water is not so easy to obtain. University of Utah researchers however, have discovered a new reservoir/aquifer in Greenland's ice sheet. The reservoir is known as a "perennial firn aquifer" and covers 27,000 square miles an area larger than the state of West Virginia. Called a firn because water persists within layers of snow and ice that doesn't melt for at least one season, researchers believe the discovery will aid in the understanding of snowmelt and ice melt as it relates to rising sea levels.
Persistent Energy Ghana Brings Solar to Those Who Need Light
December 30, 2013 08:07 AM - Justine Porter, Triple Pundit
Persistent Energy Ghana (PEG) is leading the movement to bring green energy, installing solar-powered micro-grids for the one million Ghanaian households that earn between $1 and $6 a day. PEG, a Ghanaian energy services company that launched last year, hopes to help under-electrified regions leap-frog directly from kerosene to solar in the same way that Ghana skipped over the installation of telephone lines thanks to the adoption of cell phones.
