The continuing increase in the level of carbon dioxide and other "greenhouse gases" in the Earth's atmosphere has been identified as a cause for serious concern because it may radically accelerate changes in the Earth's climate. Developing an effective strategy for managing the planet's greenhouse gases is complicated by the many and varied sources of such gases, some natural, some man-made, as well as the mechanisms that capture and "sequester" the gases. A new report sponsored by the...

Research at Greenland and Antarctic shows decline in methane and ethane levels Recent data from NSF-funded research in both Greenland and Antarctica demonstrate that fossil-fuel related emissions of both methane and ethane, two of the most abundant hydrocarbons in the atmosphere, declined at the end of the twentieth century, according to a paper published Thursday in the journal Nature. The causes of the decline in methane emission rates to the atmosphere have been puzzling scientists for...

Site design and location can minimize carbon dioxide, methane emissions An international team of scientists has amassed the largest data set to date on greenhouse gas emissions from hydroelectric reservoirs. Their analysis, published August 1 in the online version of Nature Geoscience, posits that these human-made systems emit about 1/6 of the carbon dioxide and methane previously attributed to them. Prior studies based on more limited data cautioned that hydroelectric reservoirs could be a...

MONTREAL, Aug. 2, 2011 /PRNewswire-USNewswire/ -- While international climate talks remain deadlocked, the Montreal Protocol has been methodically eliminating some of the worst chemicals contributing to global warming. International ozone negotiators meeting in Montreal last week approved country plans to phase out ozone depleting substances (ODS) that are also super greenhouse gases (GHGs) that harm the global climate. By 2015, the reductions approved last week will prevent more than...

The release of a huge amount of methane gas may have caused a massive, prehistoric extinction that gave way to the arrival of dinosaurs as the dominant life form on earth, according to a new study. Micha Ruhl and his team of researchers from the Nordic Center for Earth Evolution at the University of Copenhagen in Denmark suggest that the mass extinction of half of Earth's marine life over 200 million years ago was a result of a huge release of carbon methane into the atmosphere, which led to...

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...
