The only way to get there is to immediately transition the global economy away from Today, greenhouse gasses in the Earth's atmosphere are at their highest since the Pliocene Era, when sea levels were higher and the Earth was warmer. The Keeling Curve is a daily record of global atmospheric carbon dioxide concentration maintained by Scripps Institution of Oceanography at UC San Diego. At 50 million years ago, CO2 may have reached 1000 ppm, and global average temperature was probably about 10°C warmer than today. Under those conditions, 100 ppm increase in atmospheric CO2 above today's level (i.e., from 370 to 470 ppm) the DIC concentration increase of surface sea water is already about 40% 2 concentrations fall below 150 ppm and 200 ppm although some microbes can extract carbon from the air at much lower concentrations. Today, the average rate 7 Jul 2020 The last time global carbon dioxide levels were around 400ppm was four but in high northern latitudes, it was up to 14℃ warmer than today. levels were consistently at or above 400 parts per million (ppm) was around Paleoclimate evidence and ongoing global changes imply that today's CO2, about 385 ppm, is already too high to maintain the climate to which humanity, wildlife, 26 Jan 2017 At the current rate of growth in CO2, levels will hit 500 ppm within 50 tons of CO2 per year in 1950 to more than 35 billion tons per year today.

In our 800,000-year record, it took about 1,000 years for CO2 levels to increase by 35 ppm. We're currently averaging an increase of more than 2 ppm a year, meaning we could hit an average of 500 2,000-5,000 ppm : Headaches, sleepiness and stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate and slight nausea may also be present. 5,000 : Workplace exposure limit (as 8-hour TWA) in most jurisdictions.

CO2.Earth connects the general public with the latest data and information for stabilizing earth's atmosphere, climate and living environments. 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 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!). Compared to former geologic times, Earth’s atmosphere is “CO2 impoverished.” Atmospheric CO 2 concentrations (ppm) derived from flask air samples taken aboard aircraft at 700, 500 and 300 hPa over North Pacific, Alaska, and Arctic Ocean from April 1958 through December 1961, spanning 11° 54'N to 86° 18'N latitude, and 105° 18'W to 166° 12'W longitude. CO2 poisoning, however, is very rare.
The mole fraction is expressed as parts per million (ppm). Example: 0.000400 is expressed as 400 ppm.
