Imagine a city surrounded by a large glass dome that traps heat. How does this scenario resemble the impact of greenhouse gases on the climate?

• They cool the Earth's surface

• They trap heat in the atmosphere

• They increase the albedo of the Earth

• They decrease the amount of solar radiation reaching the Earth
