Carbon Dioxide Levels Surpass 400 PPM Levels For First Time

RedOrbit: Atmospheric carbon dioxide levels have surpassed 400 parts per million (ppm) for the first time in human history, according to data released by the National Oceanic and Atmospheric Administration (NOAA). According to USA Todays Doyle Rice, NOAA data revealed on Friday the average CO2 levels at the Mauna Loa Observatory in Hawaii over the past five days were 400.03 ppm. Those readings are important because the Mauna Loa Observatory is the oldest continuous carbon dioxide (CO2) measurement...
Climate change: swift political action can avert a carbon dioxide crisis

Guardian: The news that concentrations of carbon dioxide in our atmosphere reached a level of 400 parts per million last week might not appear to have immediate significance. The level is only a couple of units higher than last year, after all. Yet the development has undoubted importance. With the realisation that carbon dioxide levels have achieved that symbolic 400ppm figure, it is now clear that two decades of warnings from scientists have fallen on deaf ears and that our leaders have failed completely...

Dont Panic, But Carbon Dioxide Levels Are the Worst Theyve Been in Human History

Take Part: The Mauna Loa Observatory sits atop a hillside on the big island of Hawaii. And while that sounds as if it must be a place of calm and tranquility, on May 10, it became the worlds messenger of doom. Using its tracking equipment, the observatory recorded that the average amount of carbon dioxide in the atmosphere exceeded 400 parts per million (ppm) for the first time in 55 years of measurement--and quite probably the last 3 million years of Earths existence. Carbon dioxide (CO2) is the primary...
Climate Change Pushes Carbon Dioxide to Worrisome Milestone

Boise Weekly: Carbon dioxide levels in the atmosphere have surpassed a worrisome milestone for the first time in-brace yourself for this one-3 to 5 million years. Atmospheric CO2-one of the main man-made gases responsible for global warming-topped 400 parts per million, a symbolic marker that hasn't been seen since before modern human beings walked the earth. The reading was taken Friday at the National Oceanic and Atmospheric Administration's Mauna Loa Observatory in Hawaii. "It symbolizes that so far we...

A new world?: carbon dioxide concentrations in atmosphere hit 400 ppm
2013-05-11 18:10:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: For the first time since homo sapiens evolved, concentrations of carbon dioxide in the atmosphere have struck 400 parts per million (ppm) due to burning fossil fuels. The National Oceanic and Atmospheric Administration (NOAA) reports that readings of carbon dioxide at Mauna Loa Observatory in Hawaii hit the symbolic number on Thursday and are expected to continue rising in coming years. The last time concentrations were this high for a sustained period was 4-5 million years ago when sea levels were...
