    As of 2021, measured atmospheric concentrations of carbon dioxide were almost 50% higher than pre-industrial levels. [32] [33] The main sources of greenhouse gases due to human activity (also called carbon sources) are: Burning fossil fuels: Burning oil, coal and gas is estimated to have emitted 37.4 billion tonnes of CO 2-eq in 2023. [34]

    Carbon dioxide emissions from human activities are the primary cause of ocean acidification, with atmospheric carbon dioxide (CO 2) levels exceeding 422 ppm (as of 2024). [69] CO 2 from the atmosphere is absorbed by the oceans.

    The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use, land-use change and forestry. [n 2] Over the last 150 years, estimated cumulative emissions from land use and land-use change represent approximately one-third of total cumulative anthropogenic CO 2 emissions ...

    Atmospheric carbon dioxide (CO 2) concentrations from 1958 to 2023. The Keeling Curve is a graph of the annual variation and overall accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.

    They are measured in carbon dioxide-equivalents over a 100-year timescale. The Intergovernmental Panel on Climate Change (IPCC) 6th assessment report finds that the "Agriculture, Forestry and Other Land Use (AFOLU)" sector on average, accounted for 13–21% of global total anthropogenic GHG emissions in the period 2010–2019.
