Smart reforms key to global fish recovery, even with climate change

Sat, 18 Feb 2017 00:00:00 EST

(VVH Consulting) New research finds that climate change will cause dramatic impacts in the world's fisheries, but with effective management most fisheries could yield more fish and more prosperity, even with a changing climate. Relative to today, this preliminary research illustrates that effective management reforms can lead, globally, to a nearly 90 percent increase in profits, a third more fish in the water and a more than 10 percent increase in harvest by 2100 in the face of climate change.

Invitation: Global warming to cause dramatic changes in fisheries

Sat, 18 Feb 2017 00:00:00 EST

Fri, 17 Feb 2017 00:00:00 EST

(University of East Anglia) Local weather plays an important part in the retreat of the ice shelves in West Antarctica, according to new research published in the journal Nature Communications.The study led by scientists at the University of East Anglia (UEA) of the Pine Island Glacier (PIG) used a unique five-year record to study how the interactions between the ocean and the atmosphere, as well as changing currents, control how heat is transported to, and beneath, the Pine Island Ice Shelf.

DRI unmanned cloud-seeding realizes beyond visual line of sight

Thu, 16 Feb 2017 00:00:00 EST

(Desert Research Institute) Nevada's unmanned cloud-seeding research team has realized another fundamental capability in their effort toward enhancing snowfall in mountainous regions of the West. The Drone America Savant™ unmanned, fixed-wing aircraft reached an altitude of 1,500 feet and completed a one-hour beyond visual line of sight flight covering a total distance of 28 nautical miles on Wednesday, February 15, 2017. The test flight of the Savant™ aircraft was the longest unmanned, cross-country round-trip flight in Nevada history.
