英文摘要: In an influential and interesting study, Stevens (2015) suggested that the global and also Northern Hemispheric warming during the early industrial period implies that the effective radiative forcing (Faer) by anthropogenic aerosols in the year 2000 compared to 1850 cannot be more negative than -1.0Wm-2. Here results from phase 5 of the Coupled Model Intercomparison Project are analyzed and it is shown that there is little relationship between Faer and the warming trend in the early industrial period in comprehensive climate models. In particular, some models simulate a warming in the early industrial period despite a strong (very negative) Faer. The reason for this difference in results is that the global-mean log-linear scaling of Faer with anthropogenic sulfur dioxide emissions introduced and used by Stevens tends to produce a substantially larger aerosol forcing compared to climate models in the first half of the twentieth century, when SO2 emissions were concentrated over smaller regions. In turn, it shows smaller (less negative) Faer in the recent period with comparatively more widespread SO2 emissions. © 2017 American Meteorological Society. Citation statistics:
