How much will atmospheric carbon change in 10 years
Answers
Answer:
Carbon dioxide concentrations have shown several cycles of variation from about 180 parts per million during the deep glaciations of the Holocene and Pleistocene to 280 parts per million during the interglacial periods. Following the start of the Industrial Revolution, atmospheric CO2 concentration increased to over 400 parts per million and continues to increase, causing the phenomenon of global warming. As of April 2019, the average monthly level of CO2 in Earth's atmosphere exceeded 413 parts per million. The daily average concentration of atmospheric CO2 at Mauna Loa Observatory first exceeded 400 ppm on 10 May 2013 although this concentration had already been reached in the Arctic in June 2012. Each part per million by volume of CO2 in the atmosphere represents approximately 2.13 gigatonnes of carbon, or 7.82 gigatonnes of CO2. As of 2018, CO2 constitutes about 0.041% by volume of the atmosphere, (equal to 410 ppm) which corresponds to approximately 3210 gigatonnes of CO2, containing approximately 875 gigatonnes of carbon.
