In the 800,000 years before the Industrial Revolution, CO2 levels didn't surpass 300 parts per million. Homo sapiens didn't emerge until about 300,000 years ago, and some of their predecessors 2 constitutes about 0.041% by volume of the atmosphere, (equal to 410 ppm) which corresponds to approximately 3210 gigatonnes of CO 2, containing approximately 875 gigatonnes of carbon. The global mean CO 2 concentration is currently rising at a rate of approximately 2 ppm/year and accelerating. At even higher levels of CO2 can cause asphyxiation as it replaces oxygen in the blood-exposure to concentrations around 40,000 ppm is immediately dangerous to life and health. CO2 poisoning, however, is very rare. Carbon Dioxide Levels and Your Health  250 – 350 ppm + background (normal) outdoor air level For obvious reasons, the Warmists never talk about the cold of the Late Ordovician Period, when the planet’s average temperature was far lower than today’s 15 degrees centigrade, yet CO2 concentrations were nearly 12 times higher, at 4,400 ppm.

Today, we stand on the threshold of a new geologic era, which some term the "Anthropocene", one where the climate is very different to the one our ancestors knew. If fossil-fuel burning continues at a business-as-usual rate, such that humanity exhausts the reserves over the next few centuries, CO 2 will continue to rise to levels of order of 1500 ppm.

Today it is over 385 ppm and rising at about 2ppm per year. 12 Jan 2021 Atmospheric carbon dioxide (CO2) concentration will soar past a scary threshold this year, exceeding 417 parts per million (ppm) — a 50% Stay up to date on the coronavirus outbreak by signing up to our newsletter today The latest Tweets from Keeling_Curve (@Keeling_curve).

The value of 280 ppm is chosen as representative of pre-industrial air because it is close to the average of CO 2 measured and dated with high time resolution between the years 1000 and 1800 in an ice core from Law Dome, Antarctica.

All farmers should consider CO2 as a nutrient. 2021-04-06 2007-05-16 The data shows as temperature varied by 16F while CO2 varied by 90 ppm or about 5.5 ppm / F. So if CO2 is up another 100 ppm, we’d expect another 18F increase yet none at all is shown in the ice sample data. 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. >40,000 ppm CO2 levels in the atmosphere today are NOT at record high levels.

As a point of reference, pre-industrial CO2 levels were around 280 parts per million (ppm) and today, we stand at  suggest that CO2 will need to be reduced from [current levels] to at most 350 ppm. civilization, our atmosphere contained about 275 ppm of carbon dioxide. Jun 4, 2020 The concentration of CO2 in the atmosphere reached 417.2 parts per million in May, 2.4ppm higher than the peak of 414.8ppm in 2019,  250-400ppm, Normal background concentration in outdoor ambient air. 400- 1,000ppm, Concentrations typical of occupied indoor spaces with good air  By 2100 the atmospheric CO2 concentration (the gas responsible for most temperature change) will be between 540 and 970 ppm depending on the SRES   Jan 12, 2021 Atmospheric carbon dioxide (CO2) concentration will soar past a scary threshold this year, exceeding 417 parts per million (ppm) — a 50% Stay up to date on the coronavirus outbreak by signing up to our newsletter toda The atmospheric carbon dioxide concentration has risen from about 270 parts per million (ppm) before 1700 to about 355 ppm today.

The time series below shows global distribution and variation of the concentration of mid-tropospheric carbon dioxide in parts per million (ppm). CO2 concentration at the Mauna Loa Observatory reached a daily record of 421.21 Parts Per Million (PPM) on April 3. This is the first time in the recent measured record that PPM has topped 420 PPM. This map shows peak PPM values per year dating to the 1970s.

About CO2.Earth 2021-04-07 · Data are reported as a dry air mole fraction defined as the number of molecules of carbon dioxide divided by the number of all molecules in air, including CO 2 itself, after water vapor has been removed. The mole fraction is expressed as parts per million (ppm). Example: 0.000400 is expressed as 400 ppm.

This is a shortened and common abbreviation for parts per million by volume (ppmv) as opposed to mass.
