Blue and Green: For the first time in at least 800,000 years, the average level of carbon dioxide in Earths atmosphere exceeded 400 parts per million (ppm) for a full month in April. Measurements made at a National Oceanic and Atmospheric Administration (NOAA) observatory in Hawaii showed that the monthly average in April reached 401.33ppm. The Scripps Institution of Oceanography at the University of California which runs the observatory -- says it is the first time in human history that levels of the greenhouse...

Global carbon dioxide levels exceeded historic threshold throughout April
2014-05-03 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Bloomberg: The amount of carbon dioxide in the atmosphere averaged more than 400 parts per million throughout April, the first time the planets monthly average has surpassed that threshold. The data from the Scripps Institution of Oceanography at the University of California, San Diego, shows how world leaders are failing to rein in greenhouse gases that climate scientists say are warming the planet. Were running out of time, but not solutions, Ed Chen, a spokesman for the Natural Resources Defense...

Carbon dioxide in atmosphere at record level
2014-05-01 23:59:00| Climate Ark Climate Change & Global Warming Newsfeed
USA Today: For the first time in human history and likely for the first time in at least 800,000 years, the average level of carbon dioxide (CO2) in Earth's atmosphere topped 400 parts per million for an entire month. Carbon dioxide is the greenhouse gas considered to be most responsible for global warming, according to the National Oceanic and Atmospheric Administration's (NOAA) Earth System Research Lab. Scientists at the Scripps Institution of Oceanography in San Diego reported that April's average...

Dual role of carbon dioxide in photosynthesis: Pioneering findings
2014-04-14 19:18:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Researchers at Ume University in Sweden have found that carbon dioxide, in its ionic form bicarbonate, has a regulating function in the splitting of water in photosynthesis. This means that carbon dioxide has an additional role to being reduced to sugar. The pioneering work is published in the latest issue of the Proceedings of the National Academy of Sciences. It is well known that inorganic carbon in the form of carbon dioxide, CO2, is reduced in a light driven process known as photosynthesis...

Carbon Dioxide Levels Climb Into Uncharted Territory for Humans
2014-04-09 12:40:00| Climate Ark Climate Change & Global Warming Newsfeed
Mashable: The amount of carbon dioxide in the Earth's atmosphere has exceeded 402 parts per million (ppm) during the past two days of observations, which is higher than at any time in at least the past 800,000 years, according to readings from monitoring equipment on a mountaintop in Hawaii. Carbon dioxide, or CO2, is the most important long-lived greenhouse gas responsible for manmade global warming, and it is building up in the atmosphere due to the burning of fossil fuels such as coal, oil and natural gas....
