Leaders of the coal industry knew as early as the mid-1960s that burning fossil fuels causes climate change. That’s according to a recently discovered 1966 copy of the magazine Mining Congress Journal, in which the head of a now-defunct mining research company wrote that the combustion of fossil fuels was increasing carbon dioxide in the atmosphere, causing global temperature increases. He continued, writing, “Such changes in temperature will cause melting of the polar icecaps, which, in turn, would result in the inundation of many coastal cities, including New York and London.” The recently discovered article now provides evidence that both the coal and oil industries have known about catastrophic climate change for decades yet worked to cover up the evidence in order to continue burning fossil fuels.
