Energy in the Atmosphere

How does the amount of greenhouse gases in the atmosphere affect the atmosphere's temperature?

• If greenhouse gases in the atmosphere increase, they trap more heat and warm the atmosphere.
• If greenhouse gases in the atmosphere increase, they trap less heat and the atmosphere cools.
• If greenhouse gases in the atmosphere decrease, they trap more heat and warm the atmosphere.
