Rising carbon dioxide levels affect nutrients in crops, study says

LA Times: The increased concentration of carbon dioxide that comes with climate change could mean some basic food plants will carry lower concentrations of iron and zinc -- and deficiencies of those nutrients are already a "substantial global public health problem," scientists reported Wednesday. The edible portions of many of the key crops for human nutrition have decreased nutritional value when compared with the same plants grown at the present ambient [carbon dioxide]. - Study published in the journal...

Rising Carbon Dioxide Levels Zap Crops of their Nutrients

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...

The Meteoric Rise of Carbon Dioxide in 1 Video

Climate Central: April set a carbon dioxide milestone by averaging 400 parts per million for the entire month. That's uncharted territory over the course of human history, and a new data visualization makes clear just how high and fast it has risen. The march to 400 ppm might seem slow by human standards, rising just one or two parts per million each year, but it's a veritable sprint by geological standards. We know this from ice cores, which contain air bubbles that give snapshots of carbon dioxide levels over...

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...
