It is the name of the process in which infrared radiation from the Sun is trapped close to Earth's surface by polluting gases that thicken the atmosphere.

• The milhouse effect
• The sunhouse effect
• The solarflare effect
• The greenhouse effect

It is the way in which greenhouse gases contribute to global warming.

• They let sunlight pass through the atmosphere, but they prevent that heat from leaving the atmosphere.
• They don't let any sunlight pass through the atmosphere.
• They let more sunlight pass through the atmosphere and then they let that heat escape.
• They let more heat escape through the atmosphere.
