Monday, November 25, 2013 — Government calculations of total U.S. methane emissions may underestimate the true values by 50 percent, a new study finds. The results are published the week of November 25 in the early online edition of the Proceedings of the National Academy of Sciences, and cast doubt on a recent Environmental Protection Agency decision to downscale its emissions estimate.
DGE's Anna Michalak, Harvard's Scot Miller and Steven Wofsy, and colleagues used atmospheric methane observations from across North America in 2007 and 2008 to improve estimates of methane gas emissions from a variety of human sources, including agriculture and fossil fuel drilling and refining. more »
Wednesday, November 20, 2013 —What are our forests really made of? From the air, ecologist Greg Asner uses a spectrometer and high-powered lasers to map nature in meticulous kaleidoscopic 3D detail -- what he calls “a very high-tech accounting system” of carbon. In this fascinating talk, Asner gives a clear message: To save our ecosystems, we need more data, gathered in new ways.
Greg Asner’s mapping technology produces detailed, complex pictures of how humans’ activities affect our ecosystems. more »
Monday, October 28, 2013 —For the first time, researchers have been able to map the true extent of gold mining in the biologically diverse region of Madre De Dios in the Peruvian Amazon. The team led by Greg Asner combined field surveys with airborne mapping and high-resolution satellite monitoring to show that the geographic extent of mining has increased 400% from 1999 to 2012 and that the average annual rate of forest loss has tripled since the Great Recession of 2008. Until this study, thousands of small, clandestine mines that have boomed since the economic crisis have gone unmonitored. The research is published in the online early edition of the Proceedings of the National Academy of Sciences the week of October 28, 2013. more »
