Yeast is then added, converting sugar into alcohol and carbon dioxide gas.
Nematodes and bacteria capture and store carbon that otherwise contributes to global warming when allowed to overload the atmosphere in the form of carbon dioxide gas.
It was finally concluded that the lake's lower levels had become saturated by carbon dioxide gas (CO2) due to gaseous springs which bubbled up from the extinct volcano beneath.
They show that warming spells very like that of the past 100 years occurred repeatedly, long before the large-scale use of fossil fuels and the associated emissions of carbon dioxide gas were a possible factor.
It is thought that recent high rainfall had displaced the CO2-rich water at the bottom, releasing a massive bubble of carbon dioxide gas from the lake in a natural phenomenon now referred to as "lake overturn".
The U.S. Energy Information Administration says increased use of natural gas has come at the expense of coal, which tends to emit significantly more carbon dioxide than natural gas.
When anticipated supply is sufficiently high, gas undercuts coal as the fuel of choice for electrical generation, which results in reduced carbon dioxide emissions, as natural gas produces only about 50% to 70% of the carbon dioxide per unit output (depending upon your metric) that coal does.
The un-burned, leaked gas is 72 times more potent than carbon dioxide -- a greenhouse gas -- making it more damaging to the environment, Krupp said.
While natural gas is a fossil fuel that emits carbon dioxide, tapping into the gas hydrates assessed in the study is not expected to affect global warming, said Brenda Pierce, coordinator for the USGS Energy Resources Program.
Scientists presume that carbon sinks can slow the effects of global warming by trapping the main greenhouse gas, carbon dioxide.
Most studies to date suggest that shale-gas wells may lead to slightly higher carbon-dioxide emissions than conventional-gas ones because more wells are needed and fracking requires lots of power from diesel motors.
ECONOMIST: Shale gas��s poor image in Europe is largely unjustified
Most of the methane reacts with the oxygen in the water to form carbon dioxide, another greenhouse gas.
Which of the following countries had higher emissions of the greenhouse gas carbon dioxide, per capita, in 2008 than the other two?
The emissions they seek to regulate are not dirty, sooty carbon, but carbon dioxide, that harmless gas that we exhale with every breadth.
Understanding the changes caused by the volcanic eruption will help researchers predict how the oceans will respond to certain levels of the greenhouse gas carbon dioxide, Fraile-Nuez said.
MSN: Undersea eruption gives clues to effects of climate change
Clearing land to plant food for biofuel releases the greenhouse gas carbon dioxide (CO2) through ploughing and can involve deforestation, which reduces the "carbon sinks" - the trees that absorb CO2.
Government scientists said Tuesday that 2012 was among the top ten warmest on record globally and continues a trend of rising temperatures due to increasing emissions of the greenhouse gas carbon dioxide.
Yet, results from the Yale-George Mason report found that 76% of Americans support regulating carbon dioxide as a greenhouse gas pollutant, and that two-thirds believe the U.S. should pursue policies to reduce its carbon footprint.

The push for a green military comes from an Obama executive order the source of untold mischief these days which requires the Department of Defense and other agencies to cut carbon dioxide and other greenhouse gas emissions.

In addition to the fact that Howarth used a flawed method to calculate the carbon dioxide emissions from shale gas, he has even admitted that he and his team used lousy data and did not examine coal carefully.
But before Westerners begin pointing fingers at Asian countries for contributing to greenhouse gases and other anti-sustainability actions, it should be understood that while they may be growing in their contributions to deleterious effects on the earth, they still lag far behind western nations in terms of per capita production of Carbon Dioxide, the greenhouse gas identified as the greatest contributor to climate change.
Gas is a hydrocarbon, albeit the cleanest, so burning gas releases carbon dioxide into the atmosphere.
Hemp soaks up a tremendous amount of carbon dioxide, bringing the greenhouse gas equation more in to balance.
FORBES: Chronic Stupidity Drives Government to Ban Hemp Despite Benefits
Keenest of all, Denmark, Finland, the Netherlands, Norway and Sweden now tax emissions of carbon dioxide, the main greenhouse gas.
The idea is to strip carbon dioxide--a greenhouse gas--out of the smokestack.
On top of that, a lot of methane (a far more potent greenhouse gas than carbon dioxide) emerges when all this food rots.
Upgrading burns lots of carbon-dioxide-emitting natural gas, and Edwards wanted to know how much that could cost him if he exceeded emissions targets.
More controversially, Dr Epstein proposes a link between an increase in emissions of carbon dioxide, the principal greenhouse gas, and the rise of asthma.
Greenhouse gases still warm planets, carbon dioxide is still a greenhouse gas and the amount of it in the Earth's atmosphere is still shooting up.
The advantage of utilizing waste is that it would otherwise be converted into methane, which is over 20 times as effective a greenhouse gas as carbon dioxide.
