Hopefully now the message has reached politicians, companies and the accumulation of 415 ppm of carbon dioxide in the atmosphere,

Carbon dioxide concentrations have increased substantially since the beginning of the industrial era, rising from an annual average of 280 ppm in the late 1700s to 401 ppm as measured at Mauna Loa in 2015—a 43 percent increase (see Figure 1). Almost all of this increase is due to human activities. 1

Ned, "if CO2 were to go over 2000 ppm today most of that ice would (eventually) be gone." Agreed. And I certainly am not questioning the role of solar irradiance. But the geological proof that ice once existed at our South Pole -- striated bedrock among other unmistakable features -- would still be there. 2014-04-10 · There's more carbon dioxide in the atmosphere today than at any time in the past 800,000 years, according to the mountaintop observatory in Hawaii that has measured CO2 concentrations for the past 415.79 ppm #CO2 in Earth’s atmosphere on January 21, 2020 HIGHEST EVER daily average at Mauna Loa Observatory Up from 413.21 ppm a year ago (Jan Humans Have Never Lived in CO2 Concentrations Seen in Earth's Atmosphere Today: 'An Experiment on Ourselves' By Aristos Georgiou On 9/26/19 at 6:55 AM EDT Share In our 800,000-year record, it took about 1,000 years for CO2 levels to increase by 35 ppm.

Read about the CO 2 Scale for more details.; Can we see a change in the CO2 record because of COVID-19? The carbon dioxide data on Mauna Loa constitute the longest record of direct measurements of CO 2 in the atmosphere. They were started by C. David Keeling of the Scripps Institution of Oceanography in March of 1958 at a facility of the National Oceanic and Atmospheric Administration [Keeling, 1976] . CO2 concentration at the Mauna Loa Observatory reached a daily record of 421.21 Parts Per Million (PPM) on April 3.

Carbon dioxide is such a small component of Earth’s atmosphere (380 parts per million or 0.038%) that it shows up on the chart below as only a thin line (shown at 2x actual thickness, just so you can see it!). Therefore, of the 410 ppm of CO2 in the atmosphere today, human CO2 supports less than 20 ppm, and natural CO2 supports more than 390 ppm.

The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.
