Inconvenient truths come in many packages. I remember as a child the "debate" about the source of smog in Los Angeles. While I would get sick and my eyes would sting, I listened to adults argue about where smog came from. (Later on when I was working at Cal-Tech-JPL which is in the foothills of the San Gabriel mountains north of Pasadena, I would have morning coffee outside and watched the grey stuff literally form like a vapor trail along the valley's freeways). For years the public read and listened to industry, oil and auto companies protest loudly that cars were not the source of smog. Technically, this is true. Smog is formed from the action of sun and warm temperatures on the chemicals emitted by refineries, power-plants and cars. Today it is universally accepted that cars pollute and contribute to smog. A similar so-called debate about tobacco raged on for years about whether tobacco did it or did not cause cancer. Lies and more lies by the tobacco industry came to light after a whistleblower and other heros produced documents about the deliberate scientific-speak obfuscation by the tobacco industry.
As Ronald Reagan famously said, and I paraphrase, "here we go again" with the so-called global warming, climate change debate. This is not a debate but a calculated effort by a few to cast doubt in the public's mind about whether or not we should be changing our fossil fuel habits.
