After the Fall – Originally Published by Orion Magazine
When cracks began to appear in the road to the small Mexican farming town of Santiago Mitlatongo, no one really noticed. Hardly anyone paid attention to the little sinkholes that began forming in the village’s cornfields, or that the deep-rooted sabino trees lining the streets were drying up and slowly dying. Despite this area having been declared an ecological disaster zone by the World Bank, nobody imagined a catastrophe was in the making.
Are Captive Tuna Farms a Viable Alternative To Overfishing? – Originally Published by The Ecologist
Japanese scientists at Kinki University – based in Osaka, Japan – have unveiled a brand new tuna species, entitled the Kindai Tuna. After three generations of breeding this species is almost identical to its wild cousins, in terms of texture and nutrition, but is the first to be completely nurtured and grown in captivity. However, the process is still expensive and rather inefficient. And the new Kindai tuna sells more, per pound, than wild Bluefin.

Researchers Discover New Impact Crater in Canada’s Western Arctic – Originally Published by Earth Today
Researchers from the University of Saskatchewan and the Geological Survey of Canada (GSC) have discovered a massive meteor impact from millions of years ago in Canada’s western Arctic. Located on the northwestern part of Victoria Island, the impact crater, or astrobleme, is about 25 km wide and is Canada’s 30th known meteorite impact feature.
Extreme Weather and Climate Change: Caution Required but not Reckless Statements – Originally Published by The Washington Post
In the wake of punishing heat waves, historic droughts, extensive flooding and extraordinary melt activity on Greenland, many are asking if we are seeing long-predicted results of climate change, caused primarily by man-made heat-trapping greenhouse gas emissions. Recent studies on extreme events found in an Intergovernmental Panel on Climate Change (IPCC) report and the Bulletin of the American Meteorological Society suggest that such events may not be attributable to weather variability alone.
California Gathers Facts to Plan for a Hot, Dry Future – Originally Published by ENS
California could lose up to 20 percent of its hydropower generation as climate change causes high-elevation reservoirs to shrink, finds a new report from the California Natural Resources Agency and the California Energy Commission. “Climate change is expected to affect the quantity and timing of water flow in the state,” said Kaveh Madani, a former postdoctoral researcher at the University of California, Riverside’s Water Science and Policy Center who led the science team that authored the report.
Planned Upgrade Set the Stage for Indian Blackout – Originally Published by IEEE Spectrum
Both blackouts in India this past month originated with disturbances on the same transmission line, according to the National Load Despatch Centre (NLDC), which is responsible for monitoring the national grid and managing interregional links. Prior to both grid failures, the line that connects Agra, in the northern regional grid, to Bina, part of the western grid 400 kilometers farther south, faced power flow well beyond its normal operating limits.
