IPCC AR6 Synthesis Report LR Figure 2.1 (d): Humans are responsible

Formal detection and attribution studies synthesise information from climate models and observations and show that the best estimate is that all the warming observed between 1850– 1900 and 2010–2019 is caused by humans. The panel shows temperature change attributed to: total human influence; its decomposition into changes in GHG concentrations and other human drivers (aerosols, ozone and land-use change (land-use reflectance)); solar and volcanic drivers; and internal climate variability. Whiskers show likely ranges

正式的检测与归因研究综合了气候模型与观测数据，其最佳估计显示：1850-1900年至2010-2019年间观测到的所有变暖均由人类活动导致。该面板展示了以下因素归因的温度变化：人类活动的总影响；其分解为温室气体（GHG）浓度变化与其他人类驱动因素（气溶胶、臭氧及土地利用变化（土地利用反射率））；太阳与火山驱动因素；以及气候系统内部变率。须状线表示可能的范围。
