英文文献摘要：
Climate change could affect the costs and returns of livestock production by altering the thermal environment of animals thereby affecting animal health, reproduction, and the efficiency by which livestock convert feed into retained products (especially meat and milk). In the United States, concentrated livestock operations are located in a variety of climatic regions, suggesting that the industry could adapt to future changes in temperature and weather patterns resulting from global warming. However, this adaption could be costly. We use nationally representative data on dairy producers coupled with finely-scaled climate data to empirically examine how producers’ costs, returns, and production systems vary across U.S. regions as a function of the local climate.

气候变化可能会改变动物的热环境，从而影响动物健康、繁殖以及牲畜将饲料转化为保留产品(特别是肉和奶)的效率，从而影响到牲畜生产的成本和收益。在美国，集中的畜牧业经营分布在不同的气候区域，这表明该行业能够适应全球变暖导致的未来温度和天气模式的变化。然而，这种适应可能代价高昂。我们使用全国范围内具有代表性的乳品生产商数据，结合精确尺度的气候数据，以经验的方式检验生产商的成本、收益和生产系统在美国各地是如何随当地气候变化的。
