The answer is yes. For another example, it belongs to the category of aerosol. The direct radiation effect of aerosol affects the solar radiation balance of the earth through scattering ... but it belongs to the category of cooling, that is to say, the more it is, the more obvious the cooling effect is. 20 1 1 just started to discuss the polluted climate, joking that the Kyoto protocol is unfair to our country, and we have contributed so much, which should offset the warming effect brought by a large amount of carbon dioxide. Of course, this is just a joke. The atmosphere is too complex and the degree of freedom is too high. It will take several years for IPCC's climate change report to be published. However, from the perspective of direct radiation effect and indirect radiation effect of aerosol, it is cooling (the conclusion of AR4 report). Of course, black carbon or brown carbon aerosol does have a warming effect, and the research continues.
Ok, digression, let's go back to the topic of whether air pollution can affect climate change. As mentioned above, it has the function of cooling the atmosphere, but in our research, we mostly use mathematical modeling to simulate and evaluate its impact on climate change. In previous studies, we only assumed various conditions under the background of "human activities affecting climate change", and the specific mechanism research was limited by the lack of relevant knowledge and the complexity of the whole system.
