What is the greenhouse effect and how does it impact the Earth's climate?

• The greenhouse effect cools the Earth's surface by releasing heat into the atmosphere.

• The greenhouse effect only affects the climate in urban areas.

• The greenhouse effect has no impact on the Earth's climate.

• The greenhouse effect warms the Earth's surface by trapping heat in the atmosphere.

How does the greenhouse effect contribute to global warming?

• The greenhouse effect traps heat in the Earth's atmosphere, leading to an increase in global temperatures.

• The greenhouse effect only affects local temperatures, not global ones.
