HIGHLIGHTS

  • CO2 Levels exceeded 415 parts per million over the span of one week
  • The Scripps Institution of Oceanography recorded the same at the Mauno Loa Observatory, Hawaii
  • This is the first time in human history that the planet's atmosphere has had more than 415ppm CO2

 

Levels of carbon dioxide have now exceeded 415 parts per million over the span of one week. This was recorded at the Mauno Loa Observatory in Hawaii by the Scripps Institution of Oceanography. "The average growth rate is remaining on the high end," said the director of the Scripps CO2 program, Ralph Keeling. The increase is around 3 parts per million and the recent average is 2.5 ppm. As recently as 1910, atmospheric CO2 stood at 300ppm – higher than it had been for 800,000 years at least – but jumped up another 100 ppm over the next century.

The increasing proportion of carbon dioxide is important to note because it has heat absorbing properties. It absorbs and traps all the heat that the sea and land emit thus not allowing it to escape from the atmosphere. Greenhouse gases help maintain the temperature of the planet but too much of it can affect the ecosystem adversely. According to meteorologist Eric Holthaus, this is the first time in human history that the planet's atmosphere has had more than 415ppm CO2. Not just in recorded history, not just since the invention of agriculture 10,000 years ago, but since before modern humans existed millions of years ago.

It is only a matter of time before sea levels start rising and nations get submerged. Amsterdam, New Orleans, Maldives, etc. run the risk of getting submerged. Our main focus should be to reverse this trend and limit the scale of destruction.
