Q: What greenhouse gases have the biggest impact on Earth's temperature?

Flexi Says: Gases that absorb heat in the atmosphere are called greenhouse gases. Greenhouse gases include carbon dioxide (CO₂), water vapor (H₂O), methane (CH₄), ozone (O₃), nitrous oxides (NO and NO₂), and chlorofluorocarbons (CFCs). All are a normal part of the atmosphere except CFCs. Different greenhouse gases have different abilities to trap heat. For example, one CH₄ molecule traps 23 times as much heat as one CO₂ molecule. One CFC-12 molecule (a type of CFC) traps 10,600 times as much heat as one CO₂. Human actions such as burning fossil fuels have increased the levels of greenhouse gases in the atmosphere. The added gases have caused a greater greenhouse effect. The result is increased global warming.
