    The date shown when humanity reaches 1.5 °C will move closer as emissions rise, and further away as emissions decrease. An alternative view projects the time remaining to 2.0 °C of warming. [ 1 ] [ 2 ] The clock is updated every year to reflect the latest global CO 2 emissions trend and rate of climate warming. [ 1 ]

    The measurements collected at Mauna Loa Observatory show a steady increase in mean atmospheric CO 2 concentration from 313 parts per million by volume in March 1958 to 406 ppmv in November 2018, [15] with a current increase of 2.48 ± 0.26 (mean ± 2 std dev) ppmv CO 2 per year. [16] This increase in atmospheric CO 2 is due to the combustion of ...
