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....

Carbon Dioxide Levels Just Hit Their Highest Point 800,000 Years
2014-04-09 10:59:00| Climate Ark Climate Change & Global Warming Newsfeed
ThinkProgress: The concentration of carbon dioxide, the greenhouse gas that drives climate change, hit 402 parts per million this week - the highest level recorded in at least 800,000 years. The recordings came from the National Oceanic and Atmospheric Association`s Mauna Loa Observatory in Hawaii, which marked another ominous milestone last May when the 400 ppm threshold was crossed for the first time in recorded history. Carbon dioxide (CO2) levels spike every spring but this year the threshold was crossed...
Carbon dioxide in atmosphere may be reduced by deserts,study says
2014-04-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Prensa Latina: A new study has found that arid regions, among the biggest ecosystems on the planet, soak up unexpectedly large amounts of carbon. As levels of carbon dioxide (CO2) rise in the atmosphere, the deserts are likely to absorb more of the greenhouse gas and lower its impact. "They are a major sink for atmospheric carbon dioxide, so as CO2 levels go up, they'll increase their uptake of CO2 from the atmosphere," said Professor Dave Evans, from Washington State University in the US. "They'll help take...
