For the first time in up to five million years, the concentration of carbon dioxide in our atmosphere is about to reach 400 parts per million (ppm). Former NASA scientist James Hansen  warned that levels over 350ppm would destabilize the earth’s climate, but now we have far exceeded that figure with a record-breaking weekly average of 398.5ppm recorded on Monday, The Guardian  reports. Researchers at the Earth Systems Research Laboratory  in Hawaii expect we will hit the 400ppm milestone in May, 2013.

The US government has been monitoring atmospheric carbon dioxide levels  at the Mauna Loa station located at an elevation of 11,115 feet since 1958, according to The Guardian. When it was first established, CO2 levels remained at a manageable 316ppm, but in the past five decades population expansion coupled with the growth of industrialized nations hooked on fossil fuels and meat has saturated the atmosphere with heat-trapping gases .
“I wish it weren’t true but it looks like the world is going to blow through the 400ppm level without losing a beat. At this pace we’ll hit 450ppm within a few decades,” Ralph Keeling, a geologist with the Scripps Institution of Oceanography  which operates the Hawaiian observatory, told The Guardian.
Tim Lueker, an oceanographer and carbon cycle researcher with Scripps CO2 Group, said that this “sobering milestone” should be a wake up call for governments to support clean energy and slash emissions.
