从撒哈拉海到人造火山:巨型“地球工程”的利与弊
Di Yi Cai Jing· 2025-06-27 03:08
各种各样的地球工程和技术革命,在成本核算的审视目光下,终究不那么靠谱。 在2018年诺贝尔经济学奖得主威廉·诺德豪斯看来,目前应对全球气候变化的威胁,主要有三种思路。 第一种是"适应",即我们要学会应对变暖的世界,而不是企图防止它——这是那些反对采取高成本措施来减缓气 候变化的人,以及那些相信气候变化的影响微不足道的人所支持的策略,但其实任何一种应对气候变化的战略组 合中,都多多少少会包含它。 第二种就是所谓"地球工程",通过建造巨型的工程项目,引进变冷的因素,来抵消二氧化碳的温室效应,诺德豪 斯认为"这可能至少部分是有效的",但并没有得到足够坚实的证明,而且可能会有危险的副作用。 第三种则是经常被称为"减缓"的策略,主要就是采取行动"减排",这是目前国际磋商的焦点,诺德豪斯认为"从环 境的角度看,这是最安全的解决方法",但作为经济学家,他同时也指出,"短期而言它也是最昂贵的,因而是最 难实现的"。 人造火山可以"抢救"地球吗? 目前比较受青睐的一类"地球工程"项目,是想办法把阳光和热量反射回宇宙空间的"太阳辐射管理技术",通过改 变地球能量的平衡来减缓或扭转变暖的趋势,俗称让地球"变白"。 这一"白化"过程 ...
