    The concentration of carbon dioxide (CO 2) in the atmosphere reached 427 ppm (0.0427%) on a molar basis in 2024, representing 3341 gigatonnes of CO 2. [1] This is an increase of 50% since the start of the Industrial Revolution , up from 280 ppm during the 10,000 years prior to the mid-18th century.

    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.

  5. Cretaceous Thermal Maximum - Wikipedia

    en.wikipedia.org/wiki/Cretaceous_Thermal_Maximum

    During the Cretaceous Thermal Maximum (CTM), atmospheric carbon dioxide levels rose to over 1,000 parts per million (ppm) compared to the pre-industrial average of 280 ppm. Rising carbon dioxide resulted in a significant increase in the greenhouse effect , leading to elevated global temperatures. [ 1 ]

  7. Global surface temperature - Wikipedia

    en.wikipedia.org/wiki/Global_surface_temperature

    The Earth's average surface absolute temperature for the 1961–1990 period has been derived by spatial interpolation of average observed near-surface air temperatures from over the land, oceans and sea ice regions, with a best estimate of 14 °C (57.2 °F). [44] The estimate is uncertain, but probably lies within 0.5 °C of the true value. [44]
