Agence France-Presse: In another ominous sign of human-caused climate change, US government scientists said Wednesday that global carbon dioxide concentrations have reached a new monthly record of 400 parts per million. Carbon dioxide is a potent greenhouse gas, and is a harmful by-product of burning fossil fuels such as oil and coal. "For the first time since we began tracking carbon dioxide in the global atmosphere, the monthly global average concentration of this greenhouse gas surpassed 400 parts per million...

Climate milestone reached as global carbon dioxide levels surpass 400ppm
2015-05-07 12:14:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: Global carbon dioxide concentrations have surpassed 400 parts per million (ppm) for the first month since measurements began, the latest results from the National Oceanic and Atmospheric Administration (NOAA) show. Scientists have said the record is a significant climate milestone. According to the UN Intergovernmental Panel on Climate Change, the concentration of all greenhouse gases, including methane and other gasses that are not included in NOAAs measurement, must not exceed 450ppm this century...

Study: Cutting carbon dioxide saves 3,500 US lives a year

Associated Press: The Obama Administration's hotly debated plan to reduce heat-trapping carbon dioxide from the nation's power plants will save about 3,500 lives a year by cutting back on other types of pollution as well, a new independent study concludes. A study from Harvard and Syracuse University calculates the decline in heart attacks and lung disease when soot and smog are reduced - an anticipated byproduct of the president's proposed power plant rule, which aims to fight global warming by limiting carbon dioxide...

Carbon dioxide could be turned into a huge underground battery
2015-04-21 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: What if we transformed carbon dioxide from being a waste product into being a huge battery to help even out our energy supply? We could make carbon storage pay off, while solving problems of intermittent energy supply from renewables. So say Tom Buscheck from the Lawrence Livermore National Laboratory in California and his colleagues who presented a design for this type of energy storage at the European Geosciences Union general assembly last week in Vienna, Austria. Their design would be able...

Increased atmospheric carbon dioxide limits soil storage
2015-04-15 17:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Carbon dioxide, the major cause of global warming, is released to the atmosphere when oil, coal, and gasoline are burned. Soils contain the largest pool of terrestrial organic carbon, helping counteract rising carbon dioxide levels and thus potentially playing a key role in modulating climate change. Carbon accumulates in soil through many years of plant photosynthesis and is lost from soil as microscopic organisms, mostly bacteria and fungi, decompose soil carbon, converting it back to carbon dioxide...
