CO2 levels have soared to the highest they’ve ever been in human existence, shocking new data shows.
The latest CO2 reading, conducted on May 12 at Mauna Loa Observatory in Hawaii, showed that carbon dioxide levels had surpassed 415 parts per million (ppm) – reaching a level unseen in over three million years.
Daily graphs of CO2 concentration, which have been recorded by Scripps Institution of Oceanography at UC San Diego since 1958, show a 15ppm rise in the greenhouse gas since 2013.
‘This shouldn’t be happening’
Ralph Keeling, Director of Scripps CO2 Program commented: “Every year it goes up like this we should be saying ‘No, this shouldn’t be happening. It’s not normal’.
“This increase is just not sustainable in terms of energy use and in terms of what we are doing to the planet.”
‘We don’t know a planet like this’
Eric Holthaus, Meteorologist, and Writer for the environmental magazine Grist tweeted: “This is the first time in human history our 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. Since before modern humans existed millions of years ago… We don’t know a planet like this.”
