题目：Viewpoint: Air-Conditioning Will Be the End of Us
Trying to engineer hot weather out of existence in an age of man-made global warming is indefensible
P1: Earlier this week, as the temperature in New York City hit the upper 90s and the heat index topped 100, my utility provider issued a heat alert and advised customers to use air-conditioning “wisely.” It was a nice, polite gesture but also an utterly ineffectual one. After all, despite our other green tendencies, most Americans still believe that the wise way to use air conditioners is to crank them up, cooling down every room in the house — or even better, relax in the cold blasts of a movie theater or shopping mall, where someone else pays the bills. Today Americans use twice as much energy for air-conditioning as we did 20 years ago, and more than the rest of the world’s nations combined. As a climate-change adaptation strategy, this is as dumb as it gets.
P2: I’m hardly against air-conditioning. During heat waves, artificial cooling can save the lives of old, sick and frail people, and epidemiologists have shown that owning an AC unit is one of the strongest predictors of who survives during dangerously hot summer weeks. I’ve long advocated public-health programs that help truly vulnerable people, whether isolated elders in broiling urban apartments or farm workers who toil in sunbaked fields, by giving them easy access to air-conditioning.
P3: I also recognize that air conditioners can enhance productivity in offices and make factories safer for workers who might otherwise wilt in searing temperatures. Used conservatively — say, to reduce indoor temperatures to the mid-70s in rooms that, because of shortsighted design, cannot be cooled by cross-ventilation from fans and windows — air conditioners may well generate enough benefits to balance the indisputable, irreversible damage they generate. But in most situations, the case for air-conditioning is made of hot air.
P4: What’s indefensible is our habit of converting homes, offices and massive commercial outlets into igloos on summer days, regardless of how hot it is outdoors. Recently, New York City prohibited stores from pumping arctic air out onto the searing sidewalks in an attempt to lure customers while burning through fossil fuels in suicidal fashion. I can’t help but wonder whether cities like New York will ever prohibit stores from cooling their facilities below, say, 70°F. No doubt a law like that would raise even more objections than Mayor Michael Bloomberg’s attempt to ban big sodas, but it might well be necessary if we can’t turn down the dial on our own.
P5: I’m skeptical that American businesses and consumers will reduce their use of air-conditioning without new rules and regulations, especially now that natural gas has helped bring down energy bills and the short-term costs of cranking the AC are relatively low. Part of the problem is that in recent decades, the fastest-growing U.S. cities — places like Las Vegas, Phoenix and Austin — have effectively been built on air-conditioning. (This is also true in the Middle East and Asia, and as a result, global energy consumption is soaring precisely when it needs to be lowered.) Throughout the country, most designs for new office, commercial and residential property rely entirely on AC, rather than on time-honored cooling technologies such as shading from trees and cross-ventilation from windows and fans. As a result, there is now an expectation that indoor air will be frigid on even the steamiest days everywhere from the Deep South to the Great West. What’s worse, this expectation is spreading to the nations where American culture carries influence; sales of air conditioners rose 20% in India and China last year.
P6: Trying to engineer hot weather out of existence rather than adjust our culture of consumption for the age of climate change is one of our biggest environmental blind spots. If you can’t stand the heat, you should know that blasting the AC will ultimately make us all even hotter. Let’s put our air conditioners on ice before it’s too late.
这篇文章使用了让步反驳的方式，论证严谨，先从个人轶事(personal anecdote) 入手，指出目前美国大量使用空调。作者先承认空调给人们带来的积极作用，并且承认一部分人的观点，空调可以提高工作效率。接着，作者笔锋一转，但是实际上空调的使用加剧了室外温度的增长。并提出，只有有效的规则和规范，可以帮助有效减少空调使用以及减低能耗。容易识别的写作手法有 personal anectdote, statistical data,historical event, appeal to emotion 等。
