Concentrations of CO2 Hit New High in 2014, Scientists Say
2015-11-09 14:25:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The Earths climate will enter a new permanent reality from next year when concentrations of CO2 in the atmosphere are likely to pass a historic milestone, the head of the UNs weather agency has warned. The record concentrations of CO2 in the atmosphere were up 43% since pre-industrial times, said the World Meteorological Organization (WMO), prompting its secretary general Michel Jarraud to say immediate action was needed to cut CO2 emissions. The WMOs latest greenhouse gas bulletin comes...

ClimateWire: A new technique using a pair of laser-based instruments could one day help scientists more accurately detect concentrations of the greenhouse gases considered responsible for climate change. Researchers at the National Institute of Standards and Technology (NIST) and the National Oceanic and Atmospheric Administration are refining a method using two frequency combs to indirectly measure the amount of carbon dioxide, methane and water vapor over a substantial distance. A single frequency comb...
