Carbon Dioxide Soars to Record-Breaking Levels Not Seen in 800,000 Years

There is more carbon dioxide in the atmosphere than there has been for 800,000 years -- since before our species evolved.On Saturday (May 11), the levels of the greenhouse gas reached 415 parts per million (ppm), as measured by the National Oceanic and Atmospheric Administration's Mauna Loa Observatory in Hawaii. Scientists at the observatory have been measuring atmospheric carbon dioxide levels since 1958. But because of other kinds of analysis, such as those done on ancient air bubbles tra...

415.26 parts per million: CO2 levels hit historic high

The Mauna Loa Observatory in Hawaii, which has tracked atmospheric CO2 levels since the late 1950s, on Saturday morning detected 415.26 parts per million (ppm). The last time Earth's atmosphere contained this much CO2 was more than three million years ago, when global sea levels were several metres higher and parts of Antarctica were blanketed in forest. The number keeps rising and it's getting higher year after year," Wolfgang Lucht, from the Potsdam Institute for Climate Impact Research (PIK...

CO2 levels likely to stay above 400ppm for the rest of our lives, new study shows

A new study reveals that carbon dioxide (CO2) concentrations in the atmosphere are likely to remain above 400 parts per million (ppm) throughout this year and for many years to come. Scientists from the Met Office Hadley Centre and Scripps Institution of Oceanography scrutinized data from NOAA's Mauna Loa Observatory in Hawaii and forecasted that levels would not dip below 400ppm for 'our lifetimes.' According to the UN's Intergovernmental Panel on Climate Change (IPCC), CO2 concentrations o...

CO2 levels make largest recorded annual leap, Noaa data shows

The last time the Earth saw such a sustained increase was over 11 millennia ago, says US science agency. Climate Home reportsAtmospheric concentrations of carbon dioxide last year rose by the biggest margin since records began, according to a US federal science agency.Fossil fuel burning and a strong El Niño weather pattern pushed CO2 levels 3.05 parts per million (ppm) on a year earlier to 402.6 ppm, as measured at the Mauna Loa Observatory in Hawaii, the National Oceanic and Atmospheric Admini...
