Web29 de mar. de 2024 · Carbon dioxide (CO2) is the main greenhouse gas. An instrument in Hawaii records CO2. On May 9, 2013, it recorded an important event. The amount of CO2 in the air was higher than 400 parts per million (ppm). It could be the first time CO2 reached this level in human history. The last time it was that high was 3 million years ago. The concentrations of carbon dioxide in the atmosphere are expressed as parts per million by volume (abbreviated as ppmv or just ppm). To convert from the usual ppmv units to ppm mass, multiply by the ratio of the molar weight of CO2 to that of air, i.e. times 1.52 (44.01 divided by 28.96).
