By Steve Koppes, University of Chicago Geochemist Albert Colman follows trail from Kamchatka microbes into the history of Earth's atmosphere. Exotic bacteria that do not rely on oxygen may have played an important role in determining the composition of Earth's early atmosphere, according to a theory that UChicago researcher Albert Colman is testing in the scalding hot springs of a volcanic crater in Siberia. He has found that bacteria at the site produce as well as consume carbon monoxide, a...

WASHINGTON, April 21, 2011 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter (MRO) has discovered the total amount of atmosphere on Mars changes dramatically as the tilt of the planet's axis varies. This process can affect the stability of liquid water if it exists on the Martian surface and increase the frequency and severity of Martian dust storms.

Scientists said Monday that a better monitoring network for greenhouse gases is needed to warn of significant changes and to help countries keep their emission levels honest. "What we're hoping to do is see if the warming is feeding the warming, particularly in the Arctic," said Euan Nisbet, a specialist in methane emissions at the University of London. "Our monitoring network is very, very limited. We feel more observation is needed." Scientists said in published papers that such a...

Reactive Nitrogen Causes Much Higher Climate-damaging Nitrous Oxide Emissions in European Forests than Previously Estimated by the IPCC Reactive nitrogen compounds from agriculture, transport, and industry lead to increased emissions of the greenhouse gas nitrous oxide (N2O) from forests in Europe. Nitrous oxide emission from forest soils is at least twice as high as estimated so far by the Intergovernmental Panel on Climate Change (IPCC). This is one of the key messages of the first study on...

Carbon Capture and Storage: Carbon Dioxide Pressure Dissipates in Underground Reservoirs, Study Shows The debate surrounding carbon capture and storage intensifies as scientists from the Earth Sciences Division at the Lawrence Berkeley National Laboratory (Berkeley Lab) examine the capacity for storing carbon dioxide underground, in a study published today in the new journal Greenhouse Gases: Science & Technology. The study debates some of the conclusions drawn in an earlier study by...

University of Alberta researchers have determined that the influence of northern peatlands on the prehistorical record of climate change has been over estimated, but the vast northern wetlands must still be watched closely as the planet grapples with its current global warming trend. Northern peatlands, which are a boggy mixture of dead organic material and water, cover more than four million square kilometers. The largest northern peatlands occur in the subarctic regions of Canada and...

As carbon dioxide levels have risen during the last 150 years, the density of pores that allow plants to breathe has dwindled by 34 percent, restricting the amount of water vapor the plants release to the atmosphere, report scientists from Indiana University Bloomington and Utrecht University in the Netherlands in an upcoming issue of the Proceedings of the National Academy of Sciences (now online).In a separate paper, also to be published by PNAS, many of the same scientists describe a model...

Researchers develop technique to measure methane gas from cattle Methane is an extremely potent greenhouse gas. Wetlands, gas hydrates, permafrost, termites, oceans, freshwater bodies, non-wetland soils, are all natural sources of atmospheric methane; however, the majority of methane presence ca n be accredited to human-related activities. These activities include: such as fossil fuel production, biomass burning, waste management and animal husbandry. The release of methane into the...

The nearly 200,000 tons of methane released into the Gulf of Mexico during last year's Deepwater Horizon oil spill were ingested by microbes in just four months, according to a new study published in Thursday's edition of the journal Science. Methane, which made up one-fifth of the crude oil that was leaked into the Gulf following an explosion on the BP-operated rig in April 2010, sank mostly into the deepest part of the waters. There, according to what researcher David Valentine of the...

An international, NOAA-led research team took a significant step forward in understanding the atmosphere's ability to cleanse itself of air pollutants and some other gases, except carbon dioxide. The issue has been controversial for many years, with some studies suggesting the self-cleaning power of the atmosphere is fragile and sensitive to environmental changes, while others suggest greater stability. And what researchers are finding is that the atmosphere's self-cleaning capacity is rather...

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
