Some Trees Use Less Water Amid Rising Carbon Dioxide, Paper Says
2013-07-11 01:59:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: The fate of the worlds forests on a warming planet has long been one of the great unanswered questions about climate change. Now, new research is complicating the picture further, suggesting that big shifts are already under way in how forests work. A paper published Wednesday suggests that trees in at least some parts of the world are having to pull less water out of the ground to achieve a given amount of growth. Some scientists say they believe that this may be a direct response to the rising...
Better Geology Needed to Store Carbon Dioxide
2013-07-10 12:43:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: Anybody planning to burn fossil fuels without releasing greenhouse gases -- in other words, capturing and storing the carbon dioxide -- will have to think long and hard: Long, because the carbon must be kept secure for thousands of years, hard because even the hardest rocks yield under pressure. Or so say researchers looking at the pitfalls of one proposed climate change solution. Carbon capture and storage, or CCS, technology exists and is already one potential amelioration of the greenhouse...

Increasing Carbon Dioxide Levels Causing the Desert to Bloom
2013-07-09 21:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Rising levels of carbon dioxide are causing the desert to bloom, according to a new study published in the journal U.S. Geophysical Research Letters. In all, the researchers found that the increase of CO2 between the years 1982 and 2010 correlated with an 11 percent increase in foliage cover across parts of arid areas under examination in Australia, North America, the Middle East and Africa. The fertilization effect occurs where elevated CO2 enables a leaf during photosynthesis to extract more...

Trapping Carbon Dioxide Underground: Can We Do It?

Live Science: In a policy address last week, President Barack Obama made the reduction of greenhouse gas emissions in the United States a key priority in the nation's fight against climate change. Now, a newly released geological report points to a promising way to cut down on the amount of harmful carbon dioxide pumped into the atmosphere: inject and store it inside rocks deep underground. The U.S. Geological Survey (USGS) conducted a detailed assessment and found 36 regions across the country that have the...

GE Oil & Gas Awarded $147 M Contract To Support Statoil's Snhvit Field Carbon Dioxide Injection Project
2013-06-19 10:00:00| chemicalonline News Articles
GE Oil & Gas recently announced it has been awarded a $147 million engineering, procurement and construction (EPC) contract from Statoil. Under the contract, GE will supply subsea production and injection equipment for Statoil’s Snøhvit carbon dioxide (CO2) injection project, designed to provide a robust CO2 solution. The CO2 is naturally present in the reservoir and is produced with natural gas at the field. The CO2 is separated from the gas onshore
