目前的缓解努力和现有的未来承诺不足以实现《巴黎协定》的温度目标。有鉴于此，关于另外采用拟议的气候地球工程技术的可能性的研究和辩论正在加剧，这些技术要么是通过消除大气二氧化碳，要么是通过更深远的干预措施改变地球的辐射能量预算。尽管研究表明，有几种技术最终可能具有促进限制气候变化的实际潜力，但它们都处于开发的早期阶段，涉及大量的不确定性和风险，并引发伦理和治理困境。根据目前的知识，不能依靠气候地球工程技术为实现《巴黎协定》的温度目标作出重大贡献。关于用假想的气候地球工程技术补充二氧化碳减排的研究和辩论正在加紧进行。在这里，作者评估了它们的潜力、不确定性和风险，并表明还不能依赖它们为实现《巴黎协定》的温度目标做出重大贡献。
Current mitigation efforts and existing future commitments are inadequate to accomplish the Paris Agreement temperature goals. In light of this, research and debate are intensifying on the possibilities of additionally employing proposed climate geoengineering technologies, either through atmospheric carbon dioxide removal or farther-reaching interventions altering the Earth’s radiative energy budget. Although research indicates that several techniques may eventually have the physical potential to contribute to limiting climate change, all are in early stages of development, involve substantial uncertainties and risks, and raise ethical and governance dilemmas. Based on present knowledge, climate geoengineering techniques cannot be relied on to significantly contribute to meeting the Paris Agreement temperature goals. Research and debate are intensifying on complementing CO2 emissions reductions with hypothetical climate geoengineering techniques. Here, the authors assess their potentials, uncertainties and risks, and show that they cannot yet be relied on to significantly contribute to meeting the Paris Agreement temperature goals.
