治理岩土工程研究潜在近期方案的政治和技术脆弱性分析Governing Geoengineering Research A Political and Technical Vulnerability A

地球工程故意改变地球的气候，对许多人来说，是一个危险的、可怕的提议。但这一概念近年来吸引了越来越多的兴趣，因为它有可能显著改变限制未来气候变化幅度的各种选择组合。与大多数减少温室气体排放的方法不同，一些地球工程方法可以证明是快速有效和廉价的，并且可以由一个或少数国家在没有全球合作的情况下使用。Tese的特点对风险管理、国家安全和国际治理提出了重大挑战，这些挑战才刚刚开始被认真考虑。

Geoengineering—the deliberate altering of the earth’s climate—represents a risky and, for many, a frightening proposition. But the concept has attracted increasing interest in recent years because of its potential ability to signifcantly transform the portfolio of options for limiting the magnitude of future climate change. In contrast to most approaches for reducing greenhouse gas emissions, some geoengineering approaches could prove fast acting and inexpensive and could be deployed by one or a small number of nations without global cooperation. Tese characteristics present signifcant challenges for risk management, national security, and international governance that have only just begun to be seriously considered.
