Some Trees Use Less Water Amid Rising Carbon Dioxide, Paper Says

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

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...

China's Carbon Emissions Traders Await Offset Demand
2013-07-10 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Ecosystem Marketplace: Designated as Chinas first special economic zone back in 1980, the fast-growing city of Shenzhen has come to epitomize the countrys move toward market-oriented economic policies. On June 18, Shenzhen set yet another precedent when it launched the first of seven pilot programs to help pave the way for a national cap-and-trade program. Under the pilot program, 635 companies in Shenzhen, responsible for about 38% of the citys emissions, face obligations to reduce their carbon intensity by 6.68%...

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...
