Climate change is of great importance in modern times and global warming is
considered as a significant part of climate change. It is proved that human’s
emissions such as greenhouse gases are one of the main sources of global warming
(IPCC, 2018). Apart from greenhouse gases, there is another kind of matter being
released in quantity via emissions from industries and transportations and playing
an important role in global warming, which is aerosol. However, atmospheric
aerosols have the net effect of cooling towards global warming. In this paper,
climate change with respect to global warming is briefly introduced and the role of
aerosols in the atmosphere is emphasized. Besides, properties of aerosols including
dynamics and thermodynamics of aerosols as well as interactions with solar
radiation are concluded. In the end, environmental policies and solutions are
discussed.
