Global warming

Without the natural greenhouse effect, the Earth, on average, would be:

• much warmer.

• much colder.

• about the same temperature.

• We don’t know.

Earth’s atmosphere is made up of:

• primarily nitrogen and less than 1% carbon dioxide.

• only heat-trapping (or greenhouse) gases.

• primarily oxygen and less than 1% methane.

• carbon dioxide and methane, with less than 10% of it being nitrogen and oxygen

The Earth’s temperature remains stable when:

• the Earth reflects the same amount of energy as it absorbs.

• the amount of solar energy absorbed by Earth is doubled.

• the amount of radiation increases and albedo decreases.

• the amount of radiation decreases and the albedo increases.
