Day 2: Basic concepts of climate change

What is the primary greenhouse gas responsible for global warming?

• Methane
• Carbon dioxide (CO2)
• Nitrous oxide
• Ozone

How does the greenhouse effect work to trap heat in the Earth's atmosphere?

• By reflecting sunlight away from Earth
• By absorbing heat in the atmosphere
• By releasing heat into space
• By cooling the Earth's surface

What is the major source of carbon dioxide emissions resulting from human activities?

• Deforestation
• Burning fossil fuels
• Volcanic eruptions
• Solar energy

Can you explain the difference between climate change and global warming?

• Climate change is the long-term change in weather patterns; global warming is a specific type of climate change.
• Global warming is the long-term change in weather patterns; climate change is a specific type of global warming.
• They are the same thing, and the terms can be used interchangeably.
• Climate change refers to natural weather fluctuations; global warming is a human-induced process.

Which of the following is NOT a consequence of a warming planet?

• Decreased sea levels
• More frequent and severe hurricanes
• Rapid growth of polar ice caps
• Expansion of desert areas

How do greenhouse gases like carbon dioxide contribute to global warming?

• They reflect sunlight away from the Earth's surface.
• They trap heat in the atmosphere, leading to rising temperatures.
• They cool the planet by releasing excess heat into space
• They have no impact on global temperatures

What role does the natural greenhouse effect play in regulating Earth's temperature?

• It has no effect on Earth's temperature
• It cools the planet by reflecting sunlight away
• It traps just the right amount of heat to maintain a habitable climate
• It contributes to extreme temperature fluctuations
