Global warming’s paper trail

Although the details of global warming were foreign to most people in the 1980s, among the few who had a better idea than most were the companies contributing the most to it. Despite scientific uncertainties, the bottom line was this: oil firms recognized that their products added CO2 to the atmosphere, understood that this would lead to warming, and calculated the likely consequences. And then they chose to accept those risks on our behalf, at our expense, and without our knowledge. By Benjamin Franta
