Why does cutting down trees increase global warming?

• trees soak up carbon dioxide and removing them causes more carbon to stay in the atmosphere

• trees provide shade which counteracts global warming

• trees absorbs the sun's energy without radiating back into the atmosphere

• trees drain greenhouse gases like methane from soil

The gas molecules that cause the Earth's greenhouse effect are all of the following except

• carbon dioxide

• water vapor

• methane

• nitrous oxide

• oxygen

This greenhouse gas is not created in nature. It damages the protective ozone layer and is very powerful. It can be released by aerosol sprays.

• Methane (CH4)

• CFCs

• Ozone (O3)
