Carbon dioxide in atmosphere at record level
2014-05-01 23:59:00| Climate Ark Climate Change & Global Warming Newsfeed
USA Today: For the first time in human history and likely for the first time in at least 800,000 years, the average level of carbon dioxide (CO2) in Earth's atmosphere topped 400 parts per million for an entire month. Carbon dioxide is the greenhouse gas considered to be most responsible for global warming, according to the National Oceanic and Atmospheric Administration's (NOAA) Earth System Research Lab. Scientists at the Scripps Institution of Oceanography in San Diego reported that April's average...

The Bacteria That Can Mitigate Fracked Natural Gas Before It Pollutes the Atmosphere
2014-05-01 18:46:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: By the ton, methane from fracking has about 20 times the global warming effect of carbon dioxide. Researchers at a college in the United Kingdom believe they have found a tiny way to mitigate the greenhouse gas before it spreads into the atmosphere. Methylocella silvestris, a single bacterial strain found in soil and other environments around the world, is capable of growing on methane and propane, according to research by a team at the University of East Anglia that was published in Nature, a...

Carbon dioxide in atmosphere may be reduced by deserts,study says
2014-04-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Prensa Latina: A new study has found that arid regions, among the biggest ecosystems on the planet, soak up unexpectedly large amounts of carbon. As levels of carbon dioxide (CO2) rise in the atmosphere, the deserts are likely to absorb more of the greenhouse gas and lower its impact. "They are a major sink for atmospheric carbon dioxide, so as CO2 levels go up, they'll increase their uptake of CO2 from the atmosphere," said Professor Dave Evans, from Washington State University in the US. "They'll help take...

Deforestation in Sandy Soil Ecosystems Releases Most CO2 into Atmosphere
2014-04-01 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: The disruption of underground microbial communities caused by deforestation and the effects of climate change on forest ecosystems will be greater in some soil types, such as sandy soils, than in others, according to a new study led by Yale University researchers. The revelation may provide critical ecosystem-management information for areas prone to biodiversity loss, as well as highlighting which ecosystems are more resilient to widespread tree removal. Writing in the journal Global Change...
