High CO2 Makes Crops Less Nutritious
2014-05-07 13:02:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: Crops grown in the high-CO2 atmosphere of the future could be significantly less nutritious, a new study published today in Nature suggests. Based on hundreds of experiments in the field, the work reveals a new challenge as society reckons with both rising carbon emissions and malnutrition in the future. Scientists generally predict that crop yields could fall in a warmer world-though higher atmospheric CO2 by itself should raise yields, as plants find it easier to extract CO2 from the air to...
Rising CO2 Levels Find New Ways To Kill You: Lowering The Amount of Nutrients In Our Food

Fast Company: If we don't intervene, greenhouse gases may significantly reduce the amount of zinc and iron in crops around the world. Add one more consequence to the ever-growing list of climate-change repercussions: a threat to human nutrition. In a study released today in Nature, researchers reveal that rising CO2 levels are significantly reducing the amount of two critical dietary nutrients--iron and zinc--in crops. Some two billion people already have iron and zinc deficiencies, and now climate change could...

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...

Study Shows Ethanol Produces More CO2 Emissions Than Gasoline
2014-05-02 20:22:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: A Northwestern University study by an economist and a chemist reports that when fuel prices drove residents of So Paulo, Brazil, to mostly switch from ethanol to gasoline in their flexible-fuel vehicles, local ozone levels dropped 20 percent. At the same time, nitric oxide and carbon monoxide concentrations tended to go up. The four-year study is the first real-world trial looking at the effects of human behavior at the pump on urban air pollution. This empirical analysis of atmospheric pollutants,...
