Governments throughout the globe usually implement early warning systems to prevent health-related costs from exposure to extreme heat. In a warming world, this type of information-provision approach is believed to be an effective way to deal with this natural hazard, even when there is little evidence of its influence on individuals’ behavior. Using detailed information from 1 million trips recorded by a bike-sharing system in Buenos Aires, Argentina, this paper investigates the direct behavioral impact of heat warnings on cycling trips. The results show substantial avoidance behavior for female cyclists and older users: the number of trips for those groups decreases following a heat warning. Alternative specifications for temperature and falsification tests suggest that the findings are robust. As in other studies, this paper also shows that the impact is diluted as time under alert increases.

全世界的政府通常会实施预警系统，以防止与健康相关的成本暴露于极热之下。在变暖的世界中，即使很少有证据表明这种信息提供方法对个人行为的影响，也被认为是应对这种自然危害的有效方法。本文使用阿根廷布宜诺斯艾利斯的自行车共享系统记录的100万次出行的详细信息，研究了高温警告对骑车出行的直接行为影响。结果表明，女性骑车者和年长使用者的回避行为相当可观：受热警告后，这些群体的出行次数减少。温度和伪造测试的替代规范表明，这一发现是可靠的。和其他研究一样
