The rest of it has partially dissolved in the world’s oceans…. About half of the CO₂ emitted since 1850 remains in the atmosphere. For 2018 alone, global fossil fuel emissions reached 10 ± 0.5 Pg C yr−1 for the first time in history (Friedlingstein et al. According to State of the Climate in 2019from NOAA and the American Meteorological Society,įrom 1850 to 2018, 440 ± 20 Pg C (1 Pg C = 10¹⁵ g C) were emitted as CO₂ from fossil fuel burning (Friedlingstein et al. Fossil fuels like coal and oil contain carbon that plants pulled out of the atmosphere through photosynthesis over many millions of years we are returning that carbon to the atmosphere in just a few hundred years. Ĭarbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. Graph by NOAA based on data from Lüthi, et al., 2008, via NOAA NCEI Paleoclimatology Program. On the geologic time scale, the increase (orange dashed line) looks virtually instantaneous. During these cycles, CO 2 was never higher than 300 ppm.

The peaks and valleys track ice ages (low CO 2) and warmer interglacials (higher CO 2). Global atmospheric carbon dioxide concentrations (CO 2) in parts per million (ppm) for the past 800,000 years.
