claim: By that time CO2 emissions had already risen from the expanded use  of coal that had powered the industrial revolution, and emissions only  increased slowly from 3.5gigatonnes in 1910 to under 4gigatonnes by the  end of the Second World War.
evidence: Human activities since the beginning of the Industrial Revolution ( around 1750 ) have produced a 45% increase in the atmospheric concentration of carbon dioxide, from 280 ppm in 1750 to 415 ppm in 2019.
