Rising CO2 levels could reduce nutrition values of staple crops like wheat, rice and soy
2014-05-07 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: Some of the worlds most important staple crops could be rendered less nutritious by rising levels of carbon dioxide in the atmosphere, scientists have said, leading to a rise in dietary deficiencies already responsible for hundreds of thousands of deaths annually. Crops such as wheat, rice and soybeans were all found to have decreased concentrations of iron and zinc when exposed to the higher levels of CO2. Experts said that the effect, which has been observed before but never conclusively proven...

Corn crops increasingly vulnerable to hot, dry weather
2014-05-02 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: US farmers can grow more corn than ever before thanks to genetic modifications and improved planting techniques, but the crops are also increasingly vulnerable to drought, researchers said Thursday. The study in the journal Science found that "densely planted corn appears to be unexpectedly more sensitive to water scarcity," raising concerns about future food supply as the planet warms. The United States is the largest exporter of corn in the world, shipping about 40 percent of the world's...

IPCC report says climate change is bad news for crops
2014-04-10 15:56:00| Climate Ark Climate Change & Global Warming Newsfeed
Ars Technica: When it comes to projections of future global warming, most people are more interested in concrete impacts than abstract figures like average global temperature. That sort of information is contained in the second section of the latest IPCC report, which was just recently released. Among the things potentially impacted by climate change, the agricultural sector is of obvious relevance to those of us who eat food. (That includes you, Soylent fans.) Given that population growth and economic progress...
