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...

Methane Reservoir Beneath Antarctic Ice Sheet
2012-08-30 08:32:12

April Flowers for redOrbit.com - Your Universe Online A recent study of the Antarctic Ice Sheet suggests that it could be a largely overlooked source of the potent greenhouse gas methane. An international team of scientists from the University of Bristol, the University of California, Santa Cruz, the University of Alberta, Edmonton, and the University of Utrecht, demonstrate that old organic matter in sedimentary basins located beneath the Antarctic Ice Sheet may have been converted to...

Mystery About Sky-high Methane Closer To Being Solved
2012-08-22 14:31:40

Commercial natural gas was likely major factor in late-20th century stabilization Increased capture of natural gas from oil fields probably accounts for up to 70 percent of the dramatic leveling off seen in atmospheric methane at the end of the 20th century, according to new UC Irvine research being published Thursday, Aug. 23, in the journal Nature. “We can now say with confidence that, based on our data, the trend is largely a result of changes in fossil fuel use,” said...

Diseased Trees Are A New Source Of Climate Gas
2012-08-08 10:03:49

April Flowers for redOrbit.com - Your Universe Online A new study from the Yale School of Forestry & Environmental Studies asserts that diseased trees may be a significant new source of methane gas that causes climate change. The study, "Elevated Methane Concentrations in Trees of an Upland Forest," which will be published in Geophysical Research Letters sampled sixty trees at the Yale Myers Forest in northeastern Connecticut. The Yale Myers Forest is 7,480 acres of mixed...

Thawing Arctic Cryosphere Releases Trapped Methane
2012-05-22 09:10:29

Brett Smith for RedOrbit.com The edges of glaciers and Arctic permafrost are where most of the evidence of global warming can be seen, but scientists have recently been traveling to these remote locations for a different reason. Researchers from the University of Alaska at Fairbanks just published a study in the online edition of Nature Geoscience showing that methane trapped under arctic lake ice for millions of years is now being released by the melting ice. The team used both aerial...

Dinosaur Farts May Have Caused Prehistoric Warming
2012-05-07 08:58:22

Brett Smith for RedOrbit.com Dinosaurs may have had a silent, but deadly effect on their climate according to new research by scientists at two UK universities. The study, published in the May 8 edition of Current Biology, compared the digestion-related methane production of Mesozoic-era sauropods to modern cows in an attempt to determine a possible impact as the gas ripped into their prehistoric environment. "A simple mathematical model suggests that the microbes living in sauropod...

Atmospheric methane (CH4), one of the main greenhouse gases, has increased dramatically worldwide since the pre-industrial era. However, much work is needed to build on intermittent and scattered observations since the 1960s and systematic study since the 1980s. Since 1983, the World Meteorological Organization (WMO) has coordinated global in-situ measurement of methane. Quantification of methane emissions still has large uncertainties, mainly because of undersampling over most regions of the...
