Emissions Of Greenhouse Gases From Cow Manure Modified By Beetles
2013-08-22 09:26:00

University of Helsinki Cattle contribute to global warming by burping and farting large amounts of greenhouse gases. Some of the same gases are also emitted from cow pats on pastures. But now researchers from the University of Helsinki have found that beetles living in cow pats may reduce emissions of the key greenhouse gas - methane. Agriculture is one of the biggest sources of the anthropogenic greenhouse gases responsible for global warming. Among these, cattle farming for meat and...

No Clear Sign That Less Soot, Methane Reduces Global Warming
2013-08-14 08:20:43

redOrbit Staff & Wire Reports - Your Universe Online Reducing emissions of only soot and methane won't do as much to reduce global warming as some previous research has suggested, according to a new study published Monday in the Proceedings of the National Academy of Sciences (PNAS). "Cutting back only on soot and methane emissions will help the climate, but not as much as previously thought," said study author Steve Smith, a climate researcher at the Department of Energy's Pacific...

Worm Causing Methane Release Ocean Bed
2013-08-13 08:36:26

April Flowers for redOrbit.com - Your Universe Online A super-charged methane seep has been discovered in the ocean off the coast of New Zealand. The seep has created its own unique food web, resulting in elevated amounts of methane escaping from the ocean floor into the water column, according to scientists at Oregon State University. Methane is a greenhouse gas 23 times more potent than carbon dioxide at warming our atmosphere. Most of the methane in the seep is likely consumed by...

Climate New research findings from the Centre for Permafrost (CENPERM) at the Department of Geosciences and Natural Resource Management, University of Copenhagen, document that permafrost during thawing may result in a substantial release of carbon dioxide into the atmosphere and that the future water content in the soil is crucial to predict the effect of permafrost thawing. The findings may lead to more accurate climate models in the future. The permafrost is thawing and thus...

NASA Studies South America's Volcanoes, Glaciers And Deserts With Microwave Energy

SMOS Helping To Sift Through Wetlands
2013-03-22 21:07:30

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency's SMOS satellite is showing its worth in observing the wetlands, offering a better understanding of Earth's carbon cycle. SMOS is a multifaceted satellite capable of mapping soil moisture and ocean salinity, and its novel microwave sensor is able to capture images of brightness temperature to obtain this information. The satellite has been used to map freezing soil, monitor thin Arctic sea ice,...

Wetland Trees Found To Be Major Source Of Methane
2013-02-14 14:45:53

Lee Rannals for redOrbit.com - Your Universe Online While wetlands represent an enormous source of atmospheric methane, researchers taking measurements of the gas at ground level in these regions have noticed a significant drop in methane levels compared to what they have measured in the air around tropical areas. The team of scientists studied both swamps and flooded forests in the tropics. After taking ground-based measurements of methane, they found that levels of the simple organic...

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...

Man-made Methane Emissions Traced To Roman Times
2012-10-04 05:52:22

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...
