greenhouse gas

In order to investigate the greenhouse gas effect in Europe, one has to measure the concentrations of CO2 from fossil fuels at different places all over the continent.

This could be done with 14C tests of air samples, but the same types of measurements can also be carried out on plants that have absorbed CO2.

To that end one would need plant material that is known to come from a specific region and also know which year it grew in.

Construction of new coal-fired power plants in the United States is in danger of coming to a standstill, partly due to the high cost of the requirement -- whether existing or anticipated -- to capture all emissions of carbon dioxide, an important greenhouse gas.

But an MIT analysis suggests an intermediate step that could get construction moving again, allowing the nation to fend off growing electricity shortages using our most-abundant, least-expensive fuel while reducing emissions.

(Massachusetts Institute of Technology) To prevent global warming, researchers and policymakers are exploring a variety of options to significantly cut the amount of carbon dioxide that reaches the atmosphere.

One possible approach involves capturing greenhouse gases such as carbon dioxide at the source, then injecting them underground.

Now MIT engineers have come up with a new software tool to determine how much CO2 can be sequestered safely in geological formations.

NASA's first spacecraft dedicated to studying carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth's climate, has arrived at Vandenberg Air Force Base, Calif., to begin final launch preparations.

A rock found mostly in Oman can be harnessed to soak up the main greenhouse gas carbon dioxide at a rate that could help slow global warming, scientists say.

Carbon dioxide isn't the only greenhouse gas that worries climate scientists. Airborne levels of two other potent gases  are on the rise, too.

(University of Maryland) Maryland officials can reduce electricity use in the state significantly by investing revenues from the Regional Greenhouse Gas Initiative cap-and-trade auctions in energy efficiency programs, says a new study from a University of Maryland-led research team.

It adds that neighboring states might benefit as well.

Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to new research.

The research team discovered a previously undocumented layer of organic matter on top of and in the upper part of permafrost, ranging from 60 to 120 centimeters deep.

The report gives results of EPA research into the emission processes and control strategies associated with underground coal mines in the U.S.

(NOTE: Methane is a greenhouse gas in the atmosphere which ranks behind carbon dioxide as the second largest contributor to global warming.
