空气质量和气候通常被视为独立的科学和政策领域。空气质量包括污染物排放、大气变化及其对人类和生态系统健康的直接影响。气候变化涉及导致世界变暖的驱动因素及其后果。这两个科学和政策问题通过共同的污染物，如臭氧（甲烷）和炭黑，不可分割地联系在一起。这篇简短的评论着眼于围绕所谓的“短期气候强迫因素”的新科学证据，以及越来越多的人意识到，实现短期气候变化目标的一种方式可能是通过控制“空气质量”污染物。这里讨论的任何选择都不能取代减少长期存在的温室气体，如二氧化碳，这是任何长期气候变化减缓战略所必需的。概述了基本的科学，仍然存在的不确定性，以及在科学和政策背景下解决空气质量和气候问题的一些协同作用和权衡。
Air quality and climate are often treated as separate science and policy areas. Air quality encompasses the here-and-now of pollutant emissions, atmospheric transformations and their direct effect on human and ecosystem health. Climate change deals with the drivers leading to a warmer world and the consequences of that. These two science and policy issues are inexorably linked via common pollutants, such as ozone (methane) and black carbon. This short review looks at the new scientific evidence around so-called "short-lived climate forcers" and the growing realisation that a way to meet short-term climate change targets may be through the control of "air quality" pollutants. None of the options discussed here can replace reduction of long-lived greenhouse gases, such as CO2, which is required for any long-term climate change mitigation strategy. An overview is given of the underlying science, remaining uncertainties, and some of the synergies and trade-offs for addressing air quality and climate in the science and policy context.
