What is the primary role of greenhouse gases in Earth's atmosphere?
They absorb solar radiation and release it as light.
They trap infrared energy from the sun and reemit it as heat.
They reflect solar energy back into space.

What happens if there are too few greenhouse gases in the atmosphere?
Earth becomes too warm for life.
Earth becomes too cold for life.
Earth remains unaffected.
Earth becomes more humid.
What can a small change in global temperature cause?
