Atmosphere In eight steps, this animation depicts the path of
sunlight that enters the planet’s atmosphere, illustrating how
that radiation is reflected, absorbed, and emitted as heat
energy. In less than 90 seconds, an animated, graphic
description of how and why global warming occurs. You didn’t get
it in 90 seconds? Watch it again. This video was made to
accompany a GAO report on climate engineering. (Emphasis added,

Directions, and Potential Responses GAO-11-71, Aug 25, 2011
Summary: Reports of rising global temperatures have raised
questions about responses to climate change, including efforts
to (1) reduce carbon dioxide (CO2) emissions, (2) adapt to
climate change, and (3) design and develop climate engineering
technologies for deliberate, large-scale intervention in E
