The global warming movement gorged itself on reports that recent years were some of the warmest on record. But when other years, such as 2006, were cooler than recorded, global warming threatened to become a bad joke uttered through frostbitten lips. But it turns out global cooling is also caused by increased emissions of greenhouse gases. Or so we are told. So now it's called climate change, rather than global warming. That's not the only example. Take the term "greenhouse gases." Gas is never good, particularly in crowded places. And it's not a far stretch from "gas" to "pollutant." So limiting the emission of greenhouse gases--"GHGs," to the initiated--into the earth's atmosphere is really all about limiting the emission of pollutants poisoning the very air we breathe. Or so we are told, as corporations trip over themselves in the race to become the greenest. Greenhouse gases, though, if one investigates carefully, consist mostly of water vapor and carbon dioxide, the latter emitted when humans exhale. But no one would grant bragging rights to controlling emissions of water vapor and carbon dioxide. Thus, the term "greenhouse gases" was born. It's also common to hear about the "scientific consensus" that climate change is caused by manmade emissions of greenhouse gases. It's a made-up term. A "consensus" is "an opinion held by all or most" (Webster's New World College Dictionary, 4th ed. 2002.) So "scientific consensus" must be an opinion held by "all or most" scientists. Leave aside the inconvenient fact "all or most" scientists don't hold the opinion that climate change is caused by manmade emissions of greenhouse gases. "Scientific consensus" is like what Richard Dawson used to say on Family Feud: "Survey says …." Read the rest...
