This statistic represents the average level of carbon dioxide in the atmosphere worldwide between the 1880s and 2018.
Figure 1 shows that CO2 levels were lower during the glacial periods (180 PPM) and higher during warmer interglacial periods (280 PPM). Since the Industrial Revolution, there is a visible difference in CO2 level measurements in the “basin” (aka the atmosphere). This could be caused by eith...
In 2017, the concentrations of the three major GHGs, namely carbon dioxide, methane, and nitrous oxide in the atmosphere were 405.5 ppm, 1859 ppb, and 329.9 ppb, respectively2, which were approximately 46%, 157%, and 22% higher, respectively, than the levels before widespread industrialization...
The concentration of CO2 in the atmosphere has increased from approximately 277 ppm in 1750 (Joos and Spahni, 2008) at the beginning of the industrial era, to 410.5 ppm in 2019 (WMO, 2020). The increase in anthropogenic emission of greenhouse gases (GHGs), in combination with other anthropo...
Figure 1 shows thatCO2levels were lower during the glacial periods (180PPM) and higher during warmer interglacial periods (280PPM). Since theIndustrial Revolution, there is a visible difference inCO2level measurements in the “basin” (aka theatmosphere). This could be caused by either an increa...
The rock weathering thermostat has compensated for the brightening sun over time by reducing the long-term, average CO2concentration in the atmosphere by about3.4ppm per million years(Foster et al. 2017). Figure 3: As the sun has brightened, long-term averageCO2levels have reduced as a result...
The Waliguan observatory took part in the World Meteorological Organization's Global Atmosphere Watch program, along with 30 other participants. The program's 2021 global greenhouse gases bulletin, issued in October, said the carbon dioxide concentration was 415.7 ppm, slightly lower than that gauged...
