How Tracking Product Sources May Help Save World's Forests
Global businesses are increasingly pledging to obtain key commodities only from sources that do not contribute to deforestation. Now, nonprofit groups are deploying data tools that help hold these companies to their promises by tracing the origins of everything from soy to timber to beef.
2017 Sir Edmund Hillary Mountain Legacy Medal Winner: Ing. César A. Portocarrero RodrÃguez
Nepalese NGO Mountain Legacy has just announced that Peruvian engineer César Augusto Portocarrero Rodríguez will receive the Sir Edmund Hillary Mountain Legacy Medal in a public ceremony at Hotel Tibet International in Kathmandu on December 11 (International Mountain Day). César Portocarrero has directed projects to mitigate the danger of outburst floods from numerous glacial lakes in the Andes, saving thousands of lives and many millions of dollars, and he is now sharing his expertise with members of the High Mountain Adaptation Partnership (HiMAP), including Nepal, Bhutan, and several Central Asian nations
NASA Sees Tropical Cyclone 05B Form
An area of tropical low pressure designated System 99B has consolidated and developed into Tropical Cyclone 05B. On Dec. 7 the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard the NASA-NOAA Suomi NPP satellite captured a visible image of Tropical Cyclone 05B over the Anadaman and Nicobar Islands. The VIIRS image showed bands of thunderstorms wrapping around the center from the northern to the eastern quadrants over the Anadaman Islands.
Sea ice hit record lows in November
Unusually high air temperatures and a warm ocean have led to a record low Arctic sea ice extent for November, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. In the Southern Hemisphere, Antarctic sea ice extent also hit a record low for the month, caused by moderately warm temperatures and a rapid shift in circumpolar winds.
“It looks like a triple whammy—a warm ocean, a warm atmosphere, and a wind pattern all working against the ice in the Arctic,” said NSIDC director Mark Serreze.
East Greenland ice sheet has responded to climate change for the last 7.5 million years
Using marine sediment cores containing isotopes of aluminum and beryllium, a group of international researchers has discovered that East Greenland experienced deep, ongoing glacial erosion over the past 7.5 million years.
The research reconstructs ice sheet erosion dynamics in that region during the past 7.5 million years and has potential implications for how much the ice sheet will respond to future interglacial warming.
The team, made up of researchers from Lawrence Livermore National Laboratory, University of Vermont, Boston College and Imperial College London, analyzed sediments eroded from the continent and deposited in the ocean off the coast, which are like a time capsule preserving records of glacial processes. The research appears in the Dec. 8 edition of the journal, Nature.
