A number of scientific journals reported the latest alarming news that the Mauna Loa Observatory, which has tracked atmospheric Carbon dioxide levels since the late 1950's, detected 415.26 parts per million in the air Saturday.
The data is recorded as part of what is known as the Keeling Curve, which tracks climate-warming greenhouse gases in the atmosphere.
"We're racing toward a state very different from the kind humans evolved in and that civilization developed in", said geochemist Ralph Keeling of the Scripps Institution of Oceanography's Carbon dioxide program, which oversees the Manua Loa Observatory. Scientists say the Carbon dioxide levels are continuing to rise year after year when it needs to stabilise. "It's not normal", Keeling said. According to meteorologist Eric Holthaus on Twitter, this is the "first time in human history" that Earth's atmosphere has had more than 415 ppm. "This increase is just not sustainable in terms of energy use and in terms of what we are doing to the planet".
Those who believe in the dangers climate change may pose claim that humanity's Carbon dioxide emissions could eventually lead to the widespread extinction of "over a million" plant and animal species, increased flooding, sea level rises, additional forest fires, and even - at high enough atmospheric Carbon dioxide levels - impaired human cognitive function. Average sea levels are thought to have been around 50 ft higher than they are today and forests grew as far north as the Arctic, a professor of earth system science at Stanford University told NBC.
