Despite the new measurement, it’s not as if humanity hasn’t been endlessly warned that it’s on a dangerous path.
Atmospheric levels of carbon registered 415 parts per million over the weekend at one of the world’s key measuring stations, a concentration level researchers say has not existed in more than 3 million years — before the dawn of human history.
Taken at the Mauno Loa Observatory in Hawaii by the Scripps Institution of Oceanography, the measure continues the upward trend of atmospheric carbon concentration that lies at the heart of the global warming and climate crisis:
Meteorologist Eric Holthaus, a journalist who covers the climate crisis for Grist, contextualized the latest readings in a tweet that was shared widely on Sunday:
One person responded to the Holthaus tweet by asking, “How is this not breaking news on all channels all over the world?”
Rich Pancost, head of the School of Earth Sciences at the University of Bristol in the U.K., said that the best guess of the scientific community is that global atmospheric carbon levels have not been this high for “about 3 millions years… [m]aybe more.”
In the Pliocene, it was much hotter.
In the Pliocene, oceans were much higher, maybe 90 feet higher.
That is our fate, folks. That is what 415ppm produces. It is only a matter of time, and some of the sea level rise will come quickly.
Amsterdam, New Orleans, Lisbon, Miami – the list of cities that will be submerged is enormous.
