Could the history of cooling help explain global warming?
Another heat wave is expected to hit the Western United States and Canada this week, surely pushing home air conditioners  for those people lucky enough to have them  into overdrive. Writer Eric Dean Wilson explores the history of air conditioning in a new book called After Cooling: On Freon, Global Warming, and the Terrible Cost of Comfort and recently spoke with Marketplace host Kai Ryssdal about why studying cooling could paradoxically help us understand global warming. Click the audio player above to hear the conversation. The next chapter of air conditioning is uncertain, he said. When there are extreme events like life-threatening heat waves, yes, we need cooling. But the vast majority of energy for cooling in the United States is not for those events. Its for when its 80 degrees outside, which granted is hot, but its not life-threatening.  The following is an excerpt from Wilsons book about the secondary market for the ozone-depleting refrigerant (CFC-12), often referred to by the brand name Freon, that helped home air conditioning become ubiquitous in the United States. It sounded, at first, like a tall tale. In the heart of the rural Midwest, a well-known reclaimer had legendary stocks of Freon. Over the years, hed accumulated old appliances and refrigerants to sell on the secondary market. Used chillers, vintage cars, HVAC systems, HFC-134a, HCFC-22, and what was rumored to be several hundred pounds of CFC-12. The reclaimer was well connected and well respected in his community, too. Hed know where to find even more. He called himself the Iceman.  In the early trials of his refrigerant runs, Sam had little trouble tracking him down. The Iceman lived a few hours outside Chicago. The Iceman was different from Sams other clients: he wasnt connected to a public business. He made his money entirely from solo reclaiming. Sam wondered whether that meant he might have even more refrigerant than he was letting on. He told Sam to drop by anytime. After making the necessary calculations  eight hours round-trip, gas money plus emissions, four hundred pounds of CFC-12, and a pickup or two along the way, not to mention some word-of-mouth tip-offs for subsequent trips  Sam figured it was well worth it. He made arrangements. The Iceman lived far off the main highway. Isolated. Although Sam was used to meeting strangers in remote spots by then, he still grew uneasy as he neared his destination. When Sam first told me the story, I thought of a passage written by Alexis de Tocqueville, the author of Democracy in America. In 1835, Tocqueville, visiting the States from France, had written of the rural inhabitants of America: They are hardly thirty in the middle of a wilderness in which everything rejects their efforts, and they cast on each other only looks of hatred and suspicion. As if invoking the opening to Dantes Inferno, Tocqueville described a United States that, outside the cities, struck him as a great conflagration of desires at odds. Twenty-five years before the Civil War, Tocqueville noted the dissonance that you can still feel everywhere: reliance on the land but mistrust of the neighbor. He elaborated that skin color, poverty or comfort, ignorance or enlightenment have already established indestructible classifications among them; national prejudices, the prejudices of education and birth divide them and isolate them. The passage is sucked dry of hope. Only sixty years as a so-called democratic nation, and the United States was alreadyTocquevilles surprise is apparenta nation divided and isolated by indestructible classifications, chief among them skin color and access to comfort, both deeply connected. As Sam pulled up to the house  more like a compound  he saw that this wasnt going to be a typical pickup. The Icemans house was connected to a massive garage, with a backyard full of what looked like junk: rusted fridges, gas tanks, industrial chillers, and other mechanical miscellany. The home of a true scavenger. Sam pulled into the driveway, where a massive white man  the Iceman, surely  stood. Tall and broad, the Iceman looked as though he possessed the kind of useful strength that comes from working with your hands all day  beefy and intimidating, as Sam described him. Sam got out of the car. He was wearing a polo shirt and nice jeans  something he might now flag as a rookie mistake  and right away, the Iceman advanced with hostility. He asked point-blank whether Sam planned to destroy the stuff for carbon offset credits. Though Sam typically offered a half-story to clients who asked, the Iceman knew better. At the start of the Freon venture, Sam had decided to respond honestly if asked directly, even if he was unprepared for what might follow. Yes, Sam told him, were destroying it. The Iceman, using the breadth of his physical stature as emphasis, told Sam to get off his property. He refused to sell the material to a carbon guy. The eight-hour drive would amount to a net loss of time, strength, cash, and patience. A bust. The Iceman repeated himself. But for some reason, perhaps beginners bravado, Sam decided to question the root of the Icemans hostility. The Iceman told him that the carbon guys (he gestured to Sam) were cutting into his business. They were destroying a material that was valuable in the rural market  a waste. Sam pointed out that he, too, was a businessman, that this was a viable, flexible currency in which they both traded. He told the Iceman that, frankly, if he sold it to another reclaimer, even one of the bigger guys, that reclaimer would probably sell it for credits, too, since the cap-and-trade market had become increasingly more profitable. Sam said that he wanted an honest transaction but that ultimately the two of them were in it for the same reason. Yes, hed made the four-hour trip, and yes, he would be driving four hours back to his wife in Chicago, and yes, hed come especially to do business with the legendary Iceman of Illinois, whom he would pay in cash, as promised, well above the market value. Still, after considering everything that made them alike, Sam would understand if the Iceman didnt want to sell him the CFC-12  or anything else, for that matter  in the future. Without fully understanding how, Sam was suddenly answering the Icemans rapid-fire questions about the carbon market and the destruction of Freon. The Iceman grilled him about climate change, about carbon credits, about the EPA, about Sams views on the environment. The Iceman told Sam that hed been treated poorly by the carbon community  a claim he never clarified with specificity. But Sam listened patiently and tried to answer all his questions with clarity and honesty. Remarkably, they leveled. The Iceman considered Sams long drive home. He decided, in the end, to sell him the CFC-12. Here was a businessman just like him, and he saw that it wouldnt be fair to send him home empty-handed. As Sam was packing the hundreds of pounds of CFC-12 tanks into the back of his truck, the Iceman approached him. You know, he said, maybe we can do this again in the future. Maybe, he said, if I get some more CFC-12, I can sell it to you.  Excerpt from After Cooling: On Freon, Global Warming, and the Terrible Cost of Comfort by Eric Dean Wilson.
