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: Global annual mean CO 2 concentration has increased by more than 45% since the start of the Industrial Revolution, from 280 ppm during the 10,000 years up to the mid-18th century to 415 ppm as of May 2019.
