12.1.2. Natural and Human-Generated Greenhouse Gases

Try these first

1. 1.

   What is the greenhouse effect?

   Hint

   Think about gases and their role in temperature regulation.

2. 2.

   Name one greenhouse gas.

   Hint

   These gases are involved in trapping heat.

3. 3.

   What is the primary greenhouse gas responsible for climate change?

   • Ozone
   • Nitrous oxide
   • Carbon dioxide
   • Methane

   Hint

   Think about the gas associated with fossil fuel burning.

4. 4.

   True or False: Methane is less effective at trapping heat compared to carbon dioxide.

   • True
   • False

   Hint

   Reflect on the properties of both gases.

5. 5.

   Calculate the increase in temperature if carbon dioxide levels were hypothetically doubled, given that each doubling has been estimated to raise temperatures by about 1.5 to 4.5 °C.

   Hint

   Consider the range given and think about average vs. extreme scenarios.

6. 6.

   Explore the potential impact of reducing methane emissions by 50% on global warming. What could be the immediate benefits?

   Hint

   Focus on methane's short-term effects compared to long-term CO2 impacts.
