at the University of California San Diego partnered with NOAA, taking its own measurements at Mauna Loa, and found virtually the same concentrations of CO2 and the same huge leap since last year this time.
Scripps Oceanography geoscientist Ralph Keeling is in charge of the Keeling curve created by his father in the late 1950s.He remarked, “Sadly we’re setting a new record. What we’d like to see is the curve plateauing and even falling because carbon dioxide as high as 420 or 425 parts per million is not good. It shows as much as we’ve done to mitigate and reduce emissions, we still have a long way to go.
From that time to this, there were just about 280 ppm of carbon dioxide in the atmosphere. It sometimes fell a little or rose a little but it stayed in that range.
