Answer
According to An Inconvenient Truth, what is the role of infrared radiation in global warming?
(1 point)
Responses
All of the sun’s energy is converted to infrared radiation and then remains in the atmosphere. This warms the atmosphere.
Over time, infrared radiation makes the atmosphere thinner. This warms the atmosphere.
Greenhouse gases trap some infrared radiation in the atmosphere. This warms the atmosphere.
