Climate Change: Atmospheric Carbon Dioxide
WebAs the record shows, the recent increase in atmospheric CO2 concentration is unprecedented in the past 800,000 years. Atmospheric CO2 concentration surpassed 400 ppm in 2016, and the average concentration in 2024 was more than 411 ppm. Source: Based on figure by Jeremy Shakun, data from Lüthi et al., 2008 and Jouzel et al., 2007. ( … Web1 de ago. de 2024 · Over the past 800,000 years, concentrations of nitrous oxide in the atmosphere rarely exceeded 280 ppb. Levels have risen since the 1920s, however, reaching a new high of 334 ppb in 2024 (average of four sites in Figure 3). This increase is primarily due to agriculture. 3 WebAtmospheric concentrations have now broken the 400ppm threshold— considered its highest level in the last three million years. To begin to stabilise—or even reduce—atmospheric CO 2 concentrations, our emissions need to not only stabilise but also decrease significantly.
