3. What is Global Warming?
 Global warming is when the earth heats up (the
temperature rises). It happens when greenhouse gases
(carbon dioxide, water vapor, nitrous oxide, and
methane) trap heat and light from the sun in the
earth’s atmosphere, which increases the
temperature. This hurts many people, animals, and
plants. Many cannot take the change, so they die..
