世界气象组织：2023年世界气象组织空气质量与气候公报（英文版）

Air quality and climate are interconnected because the chemical species that affect both are linked, and because changes in one inevitably cause changes in the other. Human activities that release long-lived greenhouse gases into the atmosphere also lead to the enhancement of concentrations of shorter-lived ozone and PM in the atmosphere. For example, the combustion of fossil fuels (a major source of carbon dioxide (CO2)) also emits nitrogen oxide (NO) into the atmosphere, which can lead to the
