The Soils of Chile(Casanova et al.)
2013-02-12 11:39:41| Springer Environmental Sciences titles
series:World Soils Book SeriesThis book is intended for students and soil scientists who want to know about the state of the art in soil sciences in Chile. The book merges a comprehensive bibliographical review of the soil surveys carried out throughout the length and breadth of Chilean territory during the past 40 years and more recent information obtained by the authors in a number of field studies. As its starting point ...

Arctic soils produce significant amounts of CO2
2013-02-11 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Science Now: Each spring in the Arctic, the freshet-flooding triggered by melting snow-washes vast amounts of carbon-rich soil from the land into the water-both fresh water and the ocean. That's of particular interest to scientists studying global warming, because in those waters much of the carbon that's being released from melting permafrost is oxidized by bacteria into carbon dioxide, says Rose Cory, an environmental scientist at the University of North Carolina, Chapel Hill. Carbon from surface waters amounts...

Earthworms Increase Soils Greenhouse Gas Emissions
2013-02-04 14:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Most earthworms may be tiny, but a new study suggests their impact on the climate could be mighty. Researchers had long assumed the creepy crawlers help store carbon in soils by consuming fallen leaves and other decaying plant matter, which they deposit in soil in their cast, or droppings. But newer studies suggest the worms may actually increase soils' output of two key greenhouse gases, carbon dioxide and nitrous oxide. A new meta-analysis, published Sunday in the journal Nature Climate Change,...

'Warmer soils spew more carbon into air'
2013-01-21 09:59:00| Climate Ark Climate Change & Global Warming Newsfeed
Indo Asian News Service: Warmer soils spew additional carbon into the atmosphere under the impact of climate change, US research says. The study, conducted by Serita Frey, professor from the University of New Hampshire and others, throws new light on how soil bugs respond to temperature and could finetune predictions of how warming will affect the carbon dioxide (CO2) flux from soils. Activities of soil bugs release 10 times the CO2 that human do on a yearly basis. This release of CO2 has been kept in check by plants'...
Warmer soils release additional CO2 into atmosphere; Effect stabilizes over longer term
2013-01-20 22:31:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Warmer temperatures due to climate change could cause soils to release additional carbon into the atmosphere, thereby enhancing climate change - but that effect diminishes over the long term, finds a new study in the journal Nature Climate Change. The study, from UNH professor Serita Frey and co-authors from the University of California-Davis and the Marine Biological Laboratory, sheds new light on how soil microorganisms respond to temperature and could improve predictions of how climate warming...
