Nature World: Rising carbon dioxide (CO2) levels are zapping greens and legumes of their nutrients, according to a new study in the journal Nature. Pictured: Researchers using the Free Air Concentration Enrichment (FACE) system at the University of Illinois to simulate future atmospheric conditions. Rising carbon dioxide (CO2) levels are zapping greens and legumes of their nutrients, according to a new study in the journal Nature. Atmospheric CO2 concentrations are currently approaching 400 parts per million...

Rising carbon dioxide may compromise human nutrition, study says
2014-05-07 12:00:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: At the elevated levels of atmospheric CO2 anticipated by around 2050, crops that provide a large share of the global population with most of their dietary zinc and iron will have significantly reduced concentrations of those nutrients, according to a new study led by Harvard School of Public Health (HSPH). Given that an estimated two billion people suffer from zinc and iron deficiencies, resulting in a loss of 63 million life years annually from malnutrition, the reduction in these nutrients represents...

China effort to store carbon dioxide costly, but attempt must be made
2014-05-04 15:37:21| Climate Ark Climate Change & Global Warming Newsfeed
Seattle Times: Finding a way to corral and store carbon dioxide emissions, rather than vent those into the atmosphere, is considered among the most important strategies for limiting coal's contribution to climate change. Yet that technology is expensive, and requires substantial amounts of additional energy to separate, compress and pump carbon to storage sites. The United States and the European Union nations have been slow to move forward with large-scale carbon capture. So has China, where development...
April carbon dioxide levels above landmark 400ppm threshold for entire month
2014-05-04 13:28:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: For the first time in at least 800,000 years, the average level of carbon dioxide in Earths atmosphere exceeded 400 parts per million (ppm) for a full month in April. Measurements made at a National Oceanic and Atmospheric Administration (NOAA) observatory in Hawaii showed that the monthly average in April reached 401.33ppm. The Scripps Institution of Oceanography at the University of California which runs the observatory -- says it is the first time in human history that levels of the greenhouse...

Global carbon dioxide levels exceeded historic threshold throughout April
2014-05-03 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Bloomberg: The amount of carbon dioxide in the atmosphere averaged more than 400 parts per million throughout April, the first time the planets monthly average has surpassed that threshold. The data from the Scripps Institution of Oceanography at the University of California, San Diego, shows how world leaders are failing to rein in greenhouse gases that climate scientists say are warming the planet. Were running out of time, but not solutions, Ed Chen, a spokesman for the Natural Resources Defense...
