326. 星球防晒霜:太阳光反射与气候干预

from 知为谁 · host 知为谁

这篇摘录文章深入探讨了地球工程,特别是平流层气溶胶注入(SRM)作为应对全球变暖的潜在短期补充策略。文章指出,尽管减少排放至关重要,但由于全球变暖速度快于减排速度,以及永久碳移除技术规模不足,有意冷却地球的第三种方案值得探索。它以火山爆发(如皮纳图博火山)将硫化物喷入平流层导致全球降温的历史事件为例,解释了气溶胶反射阳光的原理。最后,文章详细提出了一个类似临床试验的三阶段框架来测试SRM的安全性与有效性,从少量硫化物释放开始,逐步扩大规模进行试验,以应对气候变化带来的迫切威胁。内容来源:https://worksinprogress.co/issue/sunscreen-for-the-planet/
