They knew back in 1954
Documents show industry-backed Air Pollution Foundation uncovered the severe harm climate change would wreak
The fossil fuel industry funded some of the world’s most foundational climate science as early as 1954, newly unearthed documents have shown, including the early research of Charles Keeling, famous for the so-called “Keeling curve” that has charted the upward march of the Earth’s carbon dioxide levels.
@NorthernInvader I've seen old newspaper articles from the 1920s that talk about it.
@BillieBun Yup and the first mention of a possible problem was in 1856 by amateur climate scientist Eunice Foote.
“An atmosphere of that gas [carbon dioxide] would give to our earth a high temperature," she wrote, "and if as some suppose, at one period of its history the air had mixed with it a larger proportion than at present, an increased temperature . . . must have necessarily resulted.”
@NorthernInvader We knew it, we know it,yet it doesn't stop.
