WMO: Carbon Dioxide hits 400ppm, 'Time running out'
2014-05-27 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed
United Press International: The World Meteorological Association (WMO) announced Monday that the average monthly concentration of carbon dioxide (CO2) in the northern hemisphere exceeded 400 parts per million (ppm) in April, the highest monthly average on record. A press release from the United Nations' weather agency says crossing the "threshold is of symbolic and scientific significance and reinforces evidence that the burning of fossil fuels and other human activities are responsible for the continuing increase in heat-trapping...

Northern hemisphere hits carbon dioxide milestone in April
2014-05-26 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Carbon dioxide levels throughout the northern hemisphere hit 400 parts per million (ppm) for the first time in human history in April, an ominous threshold for climate change, the World Meteorological Organization said on Monday. The 400 ppm level in the atmosphere, up 40 percent since wide use of fossil fuels began with the Industrial Revolution, is rapidly spreading southwards. First recorded in 2012 in the Arctic, it has since become the norm for the Arctic spring. The WMO expects the global...

Carbon Dioxide pushing weather around in the southern hemisphere
2014-05-16 16:30:00| Climate Ark Climate Change & Global Warming Newsfeed
ENN: So why is Antarctica is not warming as much as other continents, and why are there more droughts in southern Australia? According to new Antarctic ice core research published in Nature Climate Change, rising levels of carbon dioxide in the atmosphere are intensifying the Southern Ocean winds, which are known to deliver rain to southern Australia, but instead they are pushing them further south towards Antarctica. British Antarctic Survey's Dr. Robert Mulvaney, and co-author of the study says: "The...

Rising carbon dioxide levels affect nutrients in crops, study says
2014-05-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
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...
