In some ways, 400 ppm is just a number, another milestone that we are blasting past at a rate that is now exceeding 2 ppm per year. Over time, this number takes on greater weight. 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. Scripps also noted that the amount of CO2 accumulating in the atmosphere is accelerating. "It took over 200 years for levels to increase by 25%, but now just over 30 years later, levels are at a 50% increase," the institution said. CO2 levels are updated daily with data directly from NOAA's science lab on the slopes of Moana Loa volcano on the Big Island of Hawaii.
1 Nov 2012 would reach almost 685 parts per million (ppm) CO2-equivalents by 2050. We must act now to reverse emission trends projected under the 23 Oct 2014 Record High Carbon Dioxide Concentration. The annual increase in 2013 was 2.9 ppm, the largest year-to-year change since 1984. At the current rate of increase, the That future is now in our hands.

Berry kommer fram till att människan svarar för 18 av de 410 ppm CO2 som nu finns i atmosfären, resten (392 ppm) har naturligt ursprung (t.ex. avgasning från gradvis allt varmare hav). Den experimentella Schweiziska studien som Sture förtjänstfullt redovisar ger dock ett betydligt mindre mänskligt bidrag (4,3 ppm eller drygt 1% av den totala CO2-halten).
