crownecomngment on 2013-05-20A national disaster warning: in up to five million years, this is the first time that the concentration of carbon dioxide in our atmosphere is approximately to reach 400 parts per million (ppm). Monday on The guardian reports, 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. While in May 2013, researchers at the Earth Systems Research Laboratory in Hawaii expect we will hit the 400ppm milestone.
Aside from many other issues like global fraud for example there are many else the government should give attention to. According to The Guardian, 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. During the time when it was first ascertained, CO2 levels stayed 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. It is as if it was a national disaster warning.
This “sobering milestone” should be a wake up call for governments to support clean energy and slash emissions, said Tim Lueker, an oceanographer and carbon cycle researcher with Scripps CO2 Group.
