For more than a decade the Global Climate Coalition, a group representing industries with profits tied to fossil fuels, led an aggressive lobbying and public relations campaign against the idea that emissions of heat-trapping gases could lead to global warming.
“The role of greenhouse gases in climate change is not well understood,” the coalition said in a scientific “backgrounder” provided to lawmakers and journalists through the early 1990s, adding that “scientists differ” on the issue.
But a document filed in a federal lawsuit demonstrates that even as the coalition worked to sway opinion, its own scientific and technical experts were advising that the science backing the role of greenhouse gases in global warming could not be refuted.
“The scientific basis for the Greenhouse Effect and the potential impact of human emissions of greenhouse gases such as CO2 on climate is well established and cannot be denied,” the experts wrote in an internal report compiled for the coalition in 1995.
The coalition was financed by fees from large corporations and trade groups representing the oil, coal and auto industries, among others.
As this article goes on to note, the information revealed in these court documents demonstrates what we’ve known for a long while now…that the related energy industry PR operations used front groups to forward a strategy which the tobacco industry had used previously – promote the notion that the relevant science was in doubt (in an internal memo, written in the 70s, a tobacco industry exec had written, “…our product is doubt.”)
