OSLO (Reuters) - Human activities are causing an alarming decline in the variety of plant and animal life on Earth and jeopardizing food, clean water and energy supplies, a U.N.-backed study of biodiversity said on Friday.

Climate change will become a steadily bigger threat to biodiversity by 2050, adding to damage from pollution and forest clearance to make way for agriculture, according to more than 550 experts in a set of reports approved by 129 governments.  ...

A partnership between Toronto’s Ryerson University and The Endeavour Centre has come up with a design for a 1,100-square-foot, two-story home that produces zero net carbon emissions and energy use, uses no toxic construction materials, produces no landfill waste, and costs no more to build than a standard home of the same size.
 
The ZeroHouse “is a fully functional and sustainable home that’s different in what it achieves and how it looks and feels,” The Atmospheric Fund reports.

Climate May Quickly Drive Forest-Eating Beetles North, Says Study

Author: 

Show

Over the next few decades, global warming-related rises in winter temperatures could significantly extend the range of the southern pine beetle—one of the world’s most aggressive tree-killing insects—through much of the northern United States and southern Canada, says a new study. The beetle’s range is sharply limited by annual extreme temperature lows, but these lows are rising much faster than average temperatures—a trend that will probably drive the beetles’ spread, say the authors. The study was published today in the journal Nature Climate Change. ... Read more about Climate May Quickly Drive Forest-Eating Beetles North, Says Study
