Determining the onset of organized disinformation about global warming is critical for understanding its political history and evaluating the responsibilities of fossil fuel producers and other relevant parties today. A newly discovered archival document shows the American Petroleum Institute was promulgating false and misleading information about climate change in 1980, nearly a decade earlier than previously known, in order to promote public policies favorable to the fossil fuel industry. This finding demonstrates early use of public-facing disinformation about global warming by the petroleum industry and suggests commercial fossil fuel interests played a more obstructive role in climate change discourse and policy throughout the 1980s than previously understood.
