Why Are Scientists Genetically Modifying Trees?
April 7, 2014 10:41 AM - Kevin Mathews, Care2
The Lorax may speak for the trees, but even he might want to stop to listen to researchers' new plans to genetically alter trees. What may outwardly seem like disconcerting news just might change how paper is made for the better. The engineered trees would allow manufacturers to create paper significantly easier. Moreover, it's not just the paper industry that benefits from this change — the effects would be advantageous to the entire planet.
Desert absorption helps curtail CO2 levels
April 7, 2014 09:55 AM - Eric Sorensen, Washington State University News
Researchers led by a Washington State University biologist have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere. The findings give scientists a better handle on the earth's carbon budget — how much carbon remains in the atmosphere as CO2, contributing to global warming, and how much gets stored in the land or ocean in other carbon-containing forms.
The Melting Arctic
April 5, 2014 08:59 AM - Roger Greenway, ENN
As the Eastern US ends what seems to have been the most severe winter in memory, it is hard to remember that the global climate is still warming. A severe winter in a region doesn't mean that the entire hemisphere had an extreme winter. And it really doesn't imply much about long term trends. A key indicator of long term trends is the length of the Arctic melt season. A new study by researchers from the National Snow and Ice Data Center (NSIDC) and NASA shows that the length of the melt season for Arctic sea ice is growing by several days each decade. An earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap’s thickness. "The Arctic is warming and this is causing the melt season to last longer," said Julienne Stroeve, a senior scientist at NSIDC, Boulder and lead author of the new study, which has been accepted for publication in Geophysical Research Letters. "The lengthening of the melt season is allowing for more of the sun’s energy to get stored in the ocean and increase ice melt during the summer, overall weakening the sea ice cover."
Smog alerts for Europe
April 4, 2014 04:21 PM - Rob MacKenzie, The Ecologist
The UK news media has been buzzing with reports of air pollution alerts associated, at least in part, with the long-range transport of dust from the Sahara. Colleagues from Africa have asked why we in the UK are worried about the health effects of a relatively rare occurrence of this long-range dust all the way across Europe, when African countries experience dust storms of much higher intensity almost daily at some times of year.
Unearthing of large tusk in Arabian Desert suggests once greener pastures
April 4, 2014 09:49 AM - ENN Staff
Working in conjunction with the Saudi Commission for Tourism and Antiquities, researchers from the University of Oxford have discovered two pieces of a tusk that when combined measure six feet in length. The researchers believe it is from a Palaeoloxodon or a "straight tusked elephant". An elephant's carpal bone was recovered in a separate study done by a Swiss team in the Nefud Desert just five meters away. The sand layer dates back to approximately 325,000 years and the elephant is believed to be of the same age.
European Union Gets 23.4% of Electricity From Renewables
April 4, 2014 08:03 AM - Edouard Stenger, Clean Techies
According to official statistics from Eurobserv’ER, 23.4 percent of the electricity in the European Union came from renewable energy sources in 2012. The total output for 2012 has been estimated at 763.5 TW. This represents an important increase from 2011, when these energy sources brought "only" 20.4 percent of total electricity.

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.
H&M, Zara commit to cutting rainforest destruction out of clothing production
April 3, 2014 11:18 AM - Rhett Butler, MONGABAY.COM
H&M and Zara/Inditex, two of the world's largest clothing companies, today pledged to eliminate old-growth forest destruction from their products. The commitment lends support to a new front on efforts to cut deforestation from supply chains of global brands.
Crib mattresses expose infants to harmful emissions
April 2, 2014 03:30 PM - ENN Staff
University of Texas at Austin's Cockrell School of Engineering has found that crib mattresses expose sleeping infants to high levels of chemical emissions. Specifically, the team analyzed the foam padding from crib mattresses and found that the mattresses release significant amounts of volatile organic compounds (VOCs) which are potentially harmful chemicals found in many household items including cleaners and scented sprays.
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.
