Reuters: The world populations of fish, birds, mammals, amphibians and reptiles fell overall by 52 percent between 1970 and 2010, far faster than previously thought, the World Wildlife Fund said on Tuesday.
The conservation group's Living Planet Report, published every two years, said humankind's demands were now 50 percent more than nature can bear, with trees being felled, groundwater pumped and carbon dioxide emitted faster than Earth can recover.
"This damage is not inevitable but a consequence...

Human-Related Climate Change Led to Extreme Heat, Scientists Say
Posted by Washington Post: Juliet Eilperin on September 29th, 2014
New York Times: The savage heat waves that struck Australia in 2013 were almost certainly a direct consequence of the human release of greenhouse gases, researchers said Monday. It is perhaps the most definitive statement climate scientists have made that ties a specific weather event to global warming.
Five groups of researchers, using distinct methods, analyzed the heat that baked Australia for much of last year and continued into 2014, shutting down the Australian Open tennis tournament at one point in January....
The fingerprint of climate change on the California drought, extreme weather in 2013
Posted by Washington Post: Angela Fritz on September 29th, 2014
Washington Post: Researchers studying the fingerprint of human-caused climate change on extreme weather events in 2013 have found that it played a role in half of the events that they looked at, including the California drought and extreme heat events.
Climate change attribution — figuring out what role climate change is playing in our weather events — is a very difficult science. There are so many moving parts: ground-level weather conditions, large-scale atmospheric patterns, and global teleconnections, like...
