Which of the following is a problem that is associated with a thermal inversion?
An increase in pollutants trapped at Earth’s surface, which increases the number of cases of human respiratory problems
An increase in UV
radiation reaching Earth’s surface, which can damage plant tissue and decrease crop yield
A decrease in the release of carbon dioxide from warmer air temperatures at the Earth’s surface, which accelerates global climate change
A decrease in evaporation rates over the ocean, which increases potential for more severe thunderstorms and hurricanes
