Global Warming And Rice Production
2012-10-23 06:34:24

April Flowers for redOrbit.com - Your Universe Online A new study led by the University of California, Davis finds that more carbon dioxide in the atmosphere, coupled with rising temperatures, is making rice agriculture a larger source of the potent greenhouse gas methane. Relatively simple changes in rice cultivation, according to the study, could help reduce methane emissions. "Together, higher carbon dioxide concentrations and warmer temperatures predicted for the end of this...

April Flowers for redOrbit.com - Your Universe Online Analysis of the Greenland ice sheet is allowing scientists to trace the emissions of the greenhouse gas methane back thousands of years. A research team, led by the Niels Bohr Institute, has determined how much methane originates from natural sources and how much is due to human activity using special analytical methods. The resulting data can be dated back to Roman times and up to the present. More than half the emissions today are...
