because as much as 30 percent of the global greenhouse gas emissions are caused by agriculture. One of the main foci is an operation in the Sacramento Valley owned by the Muller brothers
Scientists, who are now observing how much of these gases are currently being released from this thawing ground,
Josep G. Canadell, a scientist in Australia who runs a global program to monitor greenhouse gases,
scientists say that the fact that methane is so much more potent than carbon dioxide as a greenhouse gas means that it will be likely be responsible for trapping as much heat as the carbon dioxide will.

The biggest advance since farming: perennial grainsperennial grains could be the biggest innovation since farming.
is number one tool the world can use to reduce greenhouse gases. Years after Foster influential project, architects
so some architects are working with synthetic biologist to create building materials that could be applied to the walls of existing buildings that could suck greenhouse gases from the air,
growing a shell that could eat greenhouse gas pollutants and strengthening buildings. The tools of synthetic biology are galvanizing the development of new forms of architecture that respond to environmental change by incorporating the dynamic properties of living systems, such as growth, repair, sensitivity and replication,

Increasing fuel efficiency is vitally important for reducing the overall transportation sector's overall greenhouse gas emissions.
Cities contribute 70 percent of global greenhouse-gas emissionscities are places of great efficiency, innovation,
they account for a staggering 70 percent of greenhouse-gas emissions. Cities are responsible for the majority of our harmful greenhouse gases.
But they are also places where the greatest efficiencies can be made. This makes it imperative that we understand the form
The urban economy types of economic activities and whether these emit large quantities of greenhouse gases;
the accounting methods used in shale gas development allow operators to roll over gains and losses creatively and amortize them across older and newer wells, wet and dry wells alike.
There is still too little work on the EROIS of shale gas and shale oil (like that produced from the Bakken Formation) to know how far they can take us,
and when the landfill is installing the gas collection system. The percent of gas that's collected increases with time.
On average, landfills don't put in gas collection for two years. If something biodegrades rapidly, much of the methane can be produced before the gas collection system is in place.
On the other hand, if something biodegrades slowly then you have an opportunity to capture most of that methane
because the gas collection system is installed. How did you conduct this research? We used an analytical framework referred to as life cycle assessment,
which the gas is managed. Â If methane is emitted into the environment, that's a net positive.
 We're thinking about all the different factors that influence the total global warming gases going into the atmosphere from the landfill
'They can demand aggressive gas collection. Have there been other studies showing this before? Nobody has asked the question that we asked

to curb greenhouse gases, focus on methaneformer U s. president Bill clinton on Thursday said that cities and the World bank should focus on methane,
to curb greenhouse gas emissions. Speaking from Sao Paolo, Brazil at the C40 meeting of mayors from the world's largest cities, Clinton said that methane--most prominently found in landfills--is low-hanging fruit that can make the biggest immediate impact
to reducing the warming effect of greenhouse gases in the atmosphere. Why? Because focusing on gases other than carbon dioxide is cheaper, faster and more easily regulated,
Clinton said. The financing has not been available for these things because they have been looked at as eyesores, not goldmines,
Methane is one of the six gases covered by the 1997 Kyoto Protocol, produced by everything from household waste to charcoal burning to gassy livestock.

EPA's stance on greenhouse gas draws legal fire from Chamber of Commercebeen stewing over this one for a few days,
But did you know that the U s. Chamber of commerce has filed actually a lawsuit with the U s. Court of appeals in the District of columbia that challenges the U s. Environment Protection Agency's decision not to reconsider its position on greenhouse gas emissions?
The Chamber's lawsuit challenges the wisdom of regulating greenhouse gases under the Clean Air Act,
which was created not to regulate greenhouse gas emissions. So, at this point I'm thinking about all the times--this year alone--our legislators have backed away from doing something about the environment.
Now companies must rely on more expensive coal-and gas-burning power generators. A lack of grass is also dramatically raising the costs to farmers in animal Feed in addition, cities with seemingly endlessly-growing levels of pollution, like Madrid, Barcelona,

Ground zero in the energy-water nexusthe oil and gas producing countries of the Middle east may be sitting pretty in fossil fuels,
ADWEC Virtually all desalination activities are powered currently by natural gas-fired cogeneration plants burning an average of 1. 73 billion cubic feet per day (Bcf/d) of gas.
Therefore, about 0. 86 Bcf/d of gas went to water desalination in 2011, which likely rose to 1 Bcf/d in 2012 (data for 2012 is not yet available).
Nationally, the UAE imports more gas than it produces. As I detailed in my last column, the nation produced around 5 Bcf in 2010,
In short, it imports almost exactly the same amount of gas as Abu dhabi uses for water desalination.
At current European gas import prices, that would be more than $12 million a day, or $4. 4 billion a year, in sacrificed revenue.
Exactly where UAE gets its gas imports, or what it pays for them, is not public information,
The emirate of Abu dhabi has a slightly better gas balance with a net surplus of 0. 11 Bcf/d in 2010, according to the Statistics Centre of Abu dhabi.
Other Middle Eastern oil and gas producers are considering similar options. UAE's next door neighbor Qatar has the world's third-largest gas reserves
and is the single largest exporter of liquefied natural gas. But like Abu dhabi, it is looking to renewables as a means of securing its water supply.

"Coskata uses existing gasification technology to convert almost any organic material into synthesis gas, which is a mix of carbon monoxide and hydrogen.
Rather than fermenting that gas or using thermo-chemical catalysts to produce ethanol, Coskata pumps it into a reactor containing bacteria that consume the gas
and excrete ethanol. Richard Tobey, Coskata's vice president of engineering, says the process yields 99.7 percent pure ethanol.
May Wu, an environmental scientist at Argonne National Laboratory, says Coskata's ethanol produces 84 percent less greenhouse gas than fossil fuel even after accounting for the energy needed to produce
