It brings home the fact that fossil fuel combustion, land use practices, and human activities have increased the CO2 concentration in Earth’s atmosphere by more the May 2020 hit a record high, 417 parts per million (ppm) carbon dioxide as measured at the Mauna Loa Observatory, which has continually measured CO2 in the atmosphere since 1958. Scripps noted that this puts atmospheric CO2 levels 50% higher than they were just prior to the industrial revolution.

“Our grandchildren will inhabit a radically altered planet, as the ocean gradually warms up in response to the buildup of heat-trapping gases,” said Scripps Institution of Oceanography, UC San Diego geoscientist Jeff Severinghaus. Right now we’re on track to create a climate unseen in 50 million years by mid-century. *This sentence was edited after posting to correct the 1958 ppm level. This article is reproduced with If CO2 level is causative, based on historical Vostok ice core samples….we should have seen a MUCH larger spike in temperature already.

Business As Usual scenarios point to ~1000ppm by 2100. I would opine that this is not good. The last time the concentration of CO2 was as high as 400 ppm was probably in the Pliocene Epoch, between 2.6 and 5.3 million years ago. Until the 20th century, it certainly hadn't exceeded 300 ppm, let alone 400 ppm, for at least 800,000 years. 2013-5-12 · But at 400 ppm, CO2 is much higher now, and it's still climbing fast.
