Because of the #MaunaLoa eruption and lava flows, the #CO2 measurement equipment that maintains the famous #Keeling Curve lost power on Nov. 28 and is not currently recording data.
Citing their post: "The Keeling Curve is considered the icon of scientific evidence that human activities are altering the planet’s #climate. It has provided incontrovertible evidence that the amount of [atmospheric] gas carbon dioxide has risen far above any levels experienced on Earth for at least three million years […] Researchers at #Scripps Institution of Oceanography, which established the Keeling Curve record at the site in 1958, are exploring options regarding the relocation of measurement equipment."
