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...
Environmentalists have long maintained that industry knew early on that the scientific evidence supported a human influence on rising temperatures, but that the evidence was ignored for the sake of companies’ fight against curbs on greenhouse gas emissions. Some environmentalists have compared the tactic to that once used by tobacco companies, which for decades insisted that the science linking cigarette smoking to lung cancer was uncertain.
Let's say global warming has widespread health effects, requires massive spending to preempt its worst consequences, and causes damages that require significant expenditures to repair. Can these polluters, who will have brought all of those things upon the public in order to make piles and piles of cash, be sued the way the tobacco companies were sued?
