Solar dimming and cloud cover deceasing were observed simultaneously in many places, and this paradox was also found over the Tibetan Plateau, one of the cleanest regions in the world. Aerosol loading is usually used to explain this phenomenon, but we show this is not the case over the Tibetan Plateau. By contrast, due to the air warming and moistening in this region, CAPE enhanced while CIN weakened over last 30 years; accordingly, deep cloud cover increased, which led to the solar dimming. In fact, no robust evidence supports the increase in aerosols over this region during this period.
