Scientists to study Amazon rainforest fate if CO2 levels rise
2014-05-15 01:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: A group of scientists from more than 20 institutions around the world will gauge the impact on the world's largest rainforest if a time comes when the planet has 30 percent more carbon dioxide (CO2) than today, according to a project launched on Wednesday. A large experiment including towers that will pump CO2 into plots of dense forests will be built in a region north of Manaus, in the Brazilian Amazonas state. Sensors and field observation will evaluate the reaction of the trees when subject...

Rising CO2 Lowers Nutrition Value Of Crops
2014-05-08 16:18:00| Climate Ark Climate Change & Global Warming Newsfeed
Redorbit: Grains, legumes and other crops that provide a large percentage of the world with most of their dietary zinc and iron will have dramatically reduced concentrations of those nutrients by 2050 due to rising levels of atmospheric carbon dioxide, according to a new study led by Harvard School of Public Health (HSPH). The researchers studied multiple varieties of wheat, rice, field peas, soybeans, maize and sorghum grown in fields with atmospheric carbon dioxide levels comparable to those expected...

Rising CO2 levels threaten human nutrition, study says
2014-05-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
CBC: When carbon dioxide in the atmosphere reaches levels anticipated for the middle of this century, some staple crops that many of the worlds poorest people depend upon for sustenance will become less nutritious, new research suggests. In a study led by the Harvard University School of Public Health and published Wednesday in the journal Nature, an international team of scientists found that iron and zinc concentrations were substantially reduced in wheat, rice, soybean and pea crops when they were...

EU's CO2 Emissions from Energy Use Dropped by 2.5% in 2013
2014-05-08 15:23:00| Climate Ark Climate Change & Global Warming Newsfeed
Softpedia: Specialists working with Eurostat, i.e. the statistical office of the European Union, have recently released a new report saying that, last year, overall carbon dioxide emissions from energy use dropped by about 2.5% when compared to 2012. To put things into perspective, it need be said that, back in 2012, the European Union's carbon dioxide emissions resulting from energy use were documented to have dropped by just 1.6% in comparison to a 2011 baseline. "Eurostat estimates that in 2013 carbon...

Swelling CO2 Cut Nutrition in Food
2014-05-08 09:27:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: A carbon dioxide-rich atmosphere could strip important food crops of their nutrients, a new study suggests. Wheat, rice, barley and certain legumes like soybeans are classified as C3 plants, which corresponds to their ability as plants to convert carbon dioxide into energy. These C3 grasses and legumes have been shown to lose up to 15 percent of zinc and iron, the top two minerals in the human body, in experiments that artificially enhanced the concentration of carbon dioxide. These elements are...
