Data from a Hawaii observatory has recorded atmospheric carbon dioxide levels over 415 ppm, marking a historic precedent
There is more carbon dioxide on the planet than ever since the dawn of humanity, according to a Hawaii observatory.
Data from the Mauna Loa Observatory in Hawaii has recorded atmospheric carbon dioxide levels at 415.26 parts per million (ppm), marking a historic precedent in the last 800,000 years, since before the evolution of homo sapiens.
“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,” tweeted Eric Holthaus, a meteorologist.
“We don’t know a planet like this.”
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. https://t.co/azVukskDWr
The macabre rise in carbon concentration levels isn’t entirely surprising.
