Blending Synthetic Air To Measure Climate Change
2014-02-27 09:59:21

National Physical Laboratory Scientists at the National Physical Laboratory (NPL) have produced a synthetic air reference standard which can be used to accurately measure levels of carbon dioxide and methane in the atmosphere. This will greatly help scientists contribute to our understanding of climate change. A paper published in Analytical Chemistry describes how researchers at NPL have created a synthetic gas standard for the first time, which is comparable to the World...

WASHINGTON, Feb. 14, 2014 /PRNewswire-USNewswire/ -- The Environmental Investigation Agency (EIA) applauds the U.S. Environmental Protection Agency (EPA) for announcing its intent to ban the use of a certain set of super greenhouse gases, hydroflurocarbons (HFCs), and open the market to a number of important climate friendly alternatives. These actions will send a strong signal to the international community that the U.S. is serious about tackling climate change as it pushes for an...

US Emissions Of Methane Are Considerably Higher Than Official Estimates
2014-02-14 09:20:13

Mark Golden - Stanford University The first thorough comparison of evidence for natural gas system leaks confirms that organizations including the Environmental Protection Agency (EPA) have underestimated US methane emissions generally, as well as those from the natural gas industry specifically. Natural gas consists predominantly of methane. Even small leaks from the natural gas system are important because methane is a potent greenhouse gas – about 30 times more potent than carbon...

Mountainous Ecosystems Acted Like A Thermostat For Millions Of Years
2014-02-06 14:21:46

University of Oxford For the first time, scientists have discovered how tree roots in the mountains may play an important role in controlling long-term global temperatures. Researchers from Oxford and Sheffield Universities have found that temperatures affect the thickness of the leaf litter and organic soil layers, as well as the rate at which the tree roots grow. In a warmer world, this means that tree roots are more likely to grow into the mineral layer of the soil, breaking down rock...

Ancient Earth Was Warmer Due To Forest Emissions And Wildfires
2014-02-06 04:13:00

[ Watch the Video: Wildfires Heated Up The Early Earth ] Lee Rannals for redOrbit.com - Your Universe Online According to a new study published in the journal Geophysical Research Letters, wildfires could explain why the Earth was so hot three million years ago. Researchers at Yale University found that volatile compounds released by ancient Earth’s forests and smoke from wildfires caused more global warming than atmospheric levels of carbon dioxide. This study provides evidence...

The tropical carbon cycle has become twice as sensitive to temperature variations over the past 50 years, new research has revealed. The research shows that a one degree rise in tropical temperature leads to around two billion extra tonnes of carbon being released per year into the atmosphere from tropical ecosystems, compared with the same tropical warming in the 1960s and 1970s. Professor Pierre Friedlingstein and Professor Peter Cox, from the University of Exeter, collaborated with...

Leyland, Lancashire (PRWEB) January 24, 2014 The oxygen depletion system suppliers are based in Bamber Bridge Leyland, Lancashire. Clients include Lancaster University, The University of Liverpool, The University of...

Earth’s CO2 And Climate Stabilized By Ancient Forests
2014-01-24 12:38:58

European Geosciences Union UK researchers have identified a biological mechanism that could explain how the Earth’s atmospheric carbon dioxide and climate were stabilized over the past 24 million years. When CO2 levels became too low for plants to grow properly, forests appear to have kept the climate in check by slowing down the removal of carbon dioxide from the atmosphere. The results are now published in Biogeosciences, an open access journal of the European Geosciences Union (EGU)....

SAN FRANCISCO, Jan. 16, 2014 /PRNewswire-USNewswire/ -- Carbon Lighthouse, a one-stop shop for organizations to profitably eliminate their carbon footprints, has successfully eliminated enough carbon to offset one year of emissions of a California power plant. By the end of 2013, Carbon Lighthouse reported a cumulative elimination of 25,777 tons of carbon over the lifetime of their energy efficiency projects. To put this number in perspective, the average annual output of a peaker...

US Power Plant Emissions Down
2014-01-10 09:13:07

University of Colorado at Boulder Power plants that use natural gas and a new technology to squeeze more energy from the fuel release far less of the greenhouse gas carbon dioxide than coal-fired power plants do, according to a new analysis accepted for publication Jan. 8 in Earth's Future, a journal of the American Geophysical Union. The so-called "combined cycle" natural gas power plants also release significantly less nitrogen oxides and sulfur dioxide, which can worsen air quality....

Earth's Atmosphere
2004-10-19 04:45:44

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...
