"The U.Va. research, just published in the journal Environmental Science & Technology, demonstrates that algae production consumes more energy, has higher greenhouse gas emissions and uses more water than other biofuel sources, such as switchgrass, canola and corn."
"Negotiators at the COP15 conference in Copenhagen didn't see eye to eye on much last month, but almost everyone agreed on one thing: To protect the planet we need to save its forests."
The U.S Fish & Wildlife Service wants to ban the importation of Burmese pythons, and eight other large constrictor snakes that threaten the Everglades.
"Our ecological footprint - what we take out of the planet - is now 1.3 times the biological capacity of the Earth.
In the words of Professor Bob Watson, Defra's chief scientific adviser and former chairman of the Intergovernmental Panel on Climate Change (IPCC), we are in danger of approaching "a point of no return".
So the action we take in the... See More next couple of decades will determine whether the stable environment on which human civilization has depended since the last Ice Age 10,000 years ago will continue. "
"Or it could be an ecological disaster, as introducing one species to combat another species often turns out to be. However, after a "detailed" study, scientists are looking at using tiny parasitic wasps as a natural solution to pesticide to protect crops."
"The first decade of the twenty-first century was the hottest since record keeping began in 1880. With an average global temperature of 14.52 degrees Celsius (58.1 degrees Fahrenheit), this decade was 0.2 degrees Celsius (0.36 degrees Fahrenheit) warmer than any previous decade. The year 2005 was the hottest on record, while 2007 and 2009 tied for second hottest. In fact, 9 of the 10 warmest years on record occurred in the past decade."
"Eight years ago, world governments made a pledge to put a halt to growing biodiversity loss by 2010. They have not succeeded. The ongoing loss of biodiversity has instead become even more severe of a threat to the planet's once-balanced ecosystems--it's become a full-on extinction crisis. Thanks to human development and expansion, species are now going extinct exponentially faster than ever before--they're dying out at the frightening speed of 1,000 times the natural rate."
"Contrary to conventional belief, as the climate warms and growing seasons lengthen subalpine forests are likely to soak up less carbon dioxide, according to a new University of Colorado at Boulder study.
As a result, more of the greenhouse gas will be left to concentrate in the atmosphere."
