EPA doles out grants to replace old diesel engines on tug boats
May 27, 2014 03:17 PM - Allison Winter, ENN
The shipping industry is one of the most under-regulated industries in the world due to outdated and international regulations that are difficult to enforce on a global scale. And as these ships enter our harbors and ports close to home, their operations have the potential to generate smog-forming emissions and other pollutants that are linked to various health problems in susceptible populations. In an effort to combat some of the pollution expelled from dirty diesel engines, the U.S. Environmental Protection Agency has allotted over one million dollars to help two specific organizations replace their old engines with less polluting models. According to the EPA, the projects will cut emissions of harmful nitrogen oxides and particulate matter among other pollutants which are linked to asthma, lung and heart disease and premature death.
Air Conditioning: Cooler on the Inside, Hotter on the Outside!
May 25, 2014 09:30 AM - Editor, ENN
We all love to be comfortable in our homes and businesses. We use air-conditioning to provide comfortable temperatures indoors. Air conditioners work basically by moving hotter air from inside to outside. Does this have an impact on climate? Global warming? A team of researchers from Arizona State University has found that releasing excess heat from air conditioners running during the night resulted in higher outside temperatures, worsening the urban heat island effect and increasing cooling demands. "We found that waste heat from air conditioning systems was maximum during the day but the mean effect was negligible near the surface. However, during the night, heat emitted from air conditioning systems increased the mean air temperature by more than 1 degree Celsius (almost 2 degrees Fahrenheit) for some urban locations," said Francisco Salamanca, a post-doctoral research scientist at Arizona State University's School of Mathematical and Statistical Sciences.
Longer growing season does not yield growth increase for trees and shrubs
May 21, 2014 09:29 AM - Robin Blackstone, ENN
As the earth's temperatures rise, some have speculated that trees and shrubs in the colder climates might experience and increase in growth as a result of the extended growing season. "Not so," says a recent study authored by a University of Washington biology and applied mathematics postdoctoral student. Her study demonstrates that bushes achieve less yearly growth when cold winter temperatures are interrupted by warm spurts that trigger growth.
Antarctica dances to Carole King's "The Earth Moves Under My Feet"
May 20, 2014 02:07 PM - Robin Blackstone, ENN
Antarctica has apparently been living by the lyrics of Carole King's 1971 hit song "The Earth Moves Under My Feet". According to a study from Newcastle University in the United Kingdom, Antarctica has been moving "rapidly". Recently published in Earth and Planetary Science Letters, the study explains why the upward motion of the Earth's crust in the Northern Antarctic Peninsula is currently taking place so quickly. While earlier studies have shown the earth is 'rebounding' due to the overlying ice sheet shrinking in response to climate change, GPS data is suggesting otherwise. The international research team led in part by Newcastle researchers has revealed that this land is rising at a remarkable rate of 15mm a year.
Reintroducing the European Bison

In a coordinated effort to reintroduce the European bison to the grasslands of southern Romania, the World Wildlife Fund for Nature (WWF) and Rewilding Europe recently brought 20 bison to the Southern Carpathians. Ten more will be reintroduced over the summer. The species has been absent for about 200 years.
Canyons in Greenland hold a lot more glacial ice than thought
May 19, 2014 04:44 PM - Editor, ENN
Greenland is now mostly white. Snow and ice and glaciers abound, but are shrinking as the climate warms. Turns out that some of the glaciers are found in canyons and the canyons are deeper than previously thought. Scientists at NASA and the University of California, Irvine (UCI), have found that canyons under Greenland's ocean-feeding glaciers are deeper and longer than previously thought, increasing the amount of Greenland's estimated contribution to future sea level rise. "The glaciers of Greenland are likely to retreat faster and farther inland than anticipated, and for much longer, according to this very different topography we have discovered," said Mathieu Morlighem, a UCI associate project scientist who is lead author of the new research paper. The results were published Sunday in the journal Nature Geoscience.
Fighting air pollution with innovation and technology
May 19, 2014 10:46 AM - ENN Editor
Air pollution has become one of the world's biggest threats to the future of our planet. Chronic air pollution shortens our lives and the lives of the ecologies around us. In parts of Asia, where air pollution is most pervasive, food crops and other plants are exhibiting signs of stress due to low air quality.
10,000-Gallons of Crude Oil Spilled in L.A.
May 16, 2014 07:23 AM - Allison Winter, ENN
Yesterday morning, black oil sprayed nearly 20 feet into the air in Atwater Village, a neighborhood in Los Angeles, California after a "valve malfunction" caused the oil to leak. The LA Fire Department (LAFD) estimates that 10,000 gallons have spilled and while much cleanup progress has been made, it will will take a few days to clean up all contamination. Crude oil was spilled across a half-mile area, according to an LAFD alert. The oil spill had created a pool approximately 40-feet wide and was knee-high in some areas.
Patience, self-control and delayed gratification

How long would you wait for six grapes? A chimpanzee will wait more than two minutes to eat six grapes, but a black lemur would rather eat two grapes now than wait any longer than 15 seconds for a bigger serving.
Go out and play!

New research confirms the health benefits associated with outdoor play for children. New research from the University of Bristol shows that while most children spend the largest amount of their after-school time indoors either alone or with their parents, hours spent outdoors with friends has the greatest positive affect on a child's level of physical activity. The correlation works out like this: children get an extra 17 minutes of physical activity for every hour of time spent outdoors.
