Question

Which of the following best explains why air pollution that was once blamed for global cooling is now considered responsible for global warming? a. Pollution began reflecting sunlight and heat rather than absorbing it. b. Evidence of global warming became overwhelming. c. Scientists mistakenly thought pollution reflected sunlight and heat rather than absorbed it. d. Congress required scientists to assign a cause to global climate change.

Answer 1

Answer: c. Scientists mistakenly thought pollution reflected sunlight and heat rather than absorbed it.

Scientist mistakenly thought pollution reflected sunlight and heat rather than absorbed it. This best explains that air pollution that was once blamed for global cooling is now considered responsible for global warming because the carbon dioxide from greenhouse effect will reflect the sunlight and will split the UV rays and prevent them to enter inside the earth. But carbon dioxide is responsible for increasing the global temperatures.

Answer 2
