Limited Nuclear War Could Halt Global Warming, Short Term, NASA Predicts

March 2nd, 2011 | by Michael Ricciardi

The scientists used a general circulation model known as ModelE (developed at NASA's Goddard Institute for Space Studies, New York). The model calculates ocean-atmosphere coupling effects in addition to allowing varying aerosol inputs. The initial input for the simulation was 5 teragrams (megatons) of black carbon particles injected into Earth's upper troposphere. This is the estimated result of the surface detonation of 100 Hiroshima-size bombs (each equivalent to 15K tons of TNT)

'Glory' Delayed – NASA's New Climate Satellite Launch Pushed Back

October 6th, 2010 | by Michael Ricciardi

NASA's Glory satellite mission to monitor key variables that impact our Earth's climate will be postponed 3 months from its original November, 2010 launch date in order to repair a faulty solar array panel. A 2009, carbon observatory satellite mission failed to deploy properly in space

'Woody' Biomass Breakthrough: Fungus is the Key

July 25th, 2010 | by Michael Ricciardi

The resurgent interest in alternative fuels has propelled interest in using biomass "feedstocks" as an energy source for liquid fuel and bio-electricity generation. But bio-fuel (and other 'commodity chemicals') derived from biomass faces one big technical challenge: how to separate the useful constituents of cellulose-based biomass (i.e., its its six-carbon, building block sugars) from the not so useful ones (such as lignin and hemicellulose)? REcetn research has confirmed that the key to biomass conversion to fuel is a fungus with the less-than-appealing name of brown rot fungus.

Global Hawk: NASA Readies New 'Robo Plane' to Probe Atmosphere [VIDEO]

May 1st, 2010 | by Michael Ricciardi

The NASA/Global Hawk team, lead by Chris Naftel at the Dryden Research Center (Edwards Air Force base), is preparing for an important remote monitoring mission called the Global Hawk Pacific campaign, or GloPac, which will be comprised of four to five separate flights over the Pacific Ocean and the Arctic
