Question

Alguém pode me ajudar com esses exercícios,por favor ? THE GREENHOUSE EFFECT

Burning of fossil fuels and elimination of trees increase carbon dioxide (CO2) in the atmosphere.
The Earth's surface radiates heat. Some escapes, but the CO2 traps the rest, increasing the temperature.
The warming increases water vapor in the air, which in turn absorbs more of the earth's heat.
Rising surface temperatures melt snow and ice. A poor reflector, the exposed ground absorbs more sunlight, and in turn melts more snow.

1) How does carbon dioxide affect the earth's temperature?
