Nature World: Acid rain and ozone depletion may have caused the Earth's most severe known mass extinction, a new study published in the journal Geology suggests. Some 250 million years ago, at the end of the Permian period, more than 90 percent of marine species and over 70 percent of terrestrial species died off, setting the scene for the day of the dinosaur. The die-off was so extreme that, according to fossil records left behind, ecological diversity was not fully restored for another several million...

Grist: A single fracking wastewater well triggered 167 earthquakes in and around Youngstown, Ohio, during a single year of operation. Thats according to a study published in the Journal of Geophysical Research by Won-Young Kim, a researcher at Columbia University. Earthquakes had never been recorded at Youngstown before 2010. Then, at the end of that year, frackers started pumping their waste from Marcellus Shale drilling projects into the 9,200-foot deep Northstar 1 injection well. Within two weeks,...
