Payback time for soil carbon from pasture conversion to sugarcane production
Sao Paulo, Brazil (SPX) Jul 04, 2014 -
The reduction of soil carbon stock caused by the conversion of pasture areas into sugarcane plantations - a very common change in Brazil in recent years - may be offset within two or three years of cultivation. The calculation appears in a study conducted by researchers at the Center for Nuclear Energy in Agriculture (CENA) of the University of Sao Paulo (USP) in collaboration with colleagues fr ...

NASA launches carbon-tracking satellite
Washington (AFP) July 02, 2014 -
NASA on Wednesday launched a satellite designed to track carbon dioxide, a leading greenhouse gas that is responsible for global warming.
The Orbiting Carbon Observatory-2 took off aboard a Delta 2 rocket at 2:56 am Pacific time (0956 GMT) from Vandenberg Air Force Base in California.
After 56 minutes of flight, the satellite separated from the second-stage rocket as planned, with no gli ...

Seeing your true colors: Standards for hyperspectral imaging
Washington DC (SPX) Jul 04, 2014 -
Today, doctors who really want to see if a wound is healing have to do a biopsy or some other invasive technique that, besides injuring an already injured patient, can really only offer information about a small area. But a technology called hyperspectral imaging offers doctors a noninvasive, painless way to discriminate between healthy and diseased tissue and reveal how well damaged tissue is h ...

ENSO and the Indian Monsoon...not as straightforward as you'd think
Washington DC (SPX) Jul 04, 2014 -
When folks hear the term El Nino, they generally think of two things. 1) A decrease in the amount of hurricanes in the Atlantic Ocean and 2) Chris Farley. Ok, they probably only think of #2, but we here at the ENSO blog are trying to broaden that viewpoint. We've already discussed US impacts during El Nino but we know it also affects global circulation.
One of ENSO's most important influen ...

More People Means More Plant Growth
Washington DC (SPX) Jul 03, 2014 -
Ecologist Thomas Mueller uses satellite data to study how the patterns of plant growth relate to the movement of caribou and gazelle. The research sparked an idea: Would the footprint of human activity show up in the data?
Mueller, of the University of Maryland in College Park (now at the Biodiversity and Climate Research Center in Frankfurt) teamed up with university and NASA colleagues t ...
