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

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...

A more potent greenhouse gas than carbon dioxide, methane emissions leap as Earth warms
2014-03-28 01:45:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: While carbon dioxide is typically painted as the bad boy of greenhouse gases, methane is roughly 30 times more potent as a heat-trapping gas. New research in the journal Nature indicates that for each degree that Earth's temperature rises, the amount of methane entering the atmosphere from microorganisms dwelling in lake sediment and freshwater wetlands -- the primary sources of the gas -- will increase several times. As temperatures rise, the relative increase of methane emissions will outpace...

Carbon Dioxide Transmitter aids on-demand ventilation.
2014-03-03 14:30:30| Industrial Newsroom - All News for Today
To help prevent energy losses from over ventilation while also maintaining indoor air quality (IAQ), Series CDX CO<sub>2</sub> sensor employs logic algorithm that eliminates need for manual calibration in applications where indoor CO2 level drops to outside levels during unoccupied periods. Sensing range is 0–2,000 PPM, accuracy is ±30 ppm or 3% of reading (whichever is higher), and stability is <2% FS over 15 years. Product uses non-dispersive infrared absorption and offers response time of 5 sec.
