What is the basic mechanism of the greenhouse effect described by the speaker?

A) The sun’s rays bounce off the ice caps and freeze the atmosphere. B) The Earth produces its own heat which is cooled down by the atmosphere. C) Gases in the atmosphere trap the sun’s heat, keeping the Earth warm enough to sustain life.

2. What is the primary human activity that has drastically increased greenhouse gases?

A) Breathing too heavily during exercise. B) The burning of fossil fuels like coal, oil, and natural gas for energy. C) Planting too many trees in urban areas.

3. Which specific gas is mentioned as the largest contributor to human-caused global warming?

A) Carbon Dioxide (CO2) B) Nitrous Oxide (N2O) C) Oxygen (O2)

4. According to the speaker, how do scientists know what historical CO2 levels were like?

A) They analyze air bubbles trapped deep within ancient ice cores from Antarctica and Greenland. B) They guess based on ancient historical texts. C) They use time machines to go back and measure it.

5. What is one of the most visible consequences of rising global temperatures mentioned?

A) The oceans completely drying up. B) Animals learning to adapt instantly to heat. C) The rapid melting of glaciers and polar ice caps, leading to rising sea levels.

6. How does ocean acidification occur?

A) When the ocean absorbs large amounts of excess CO2 from the atmosphere, changing its chemistry. B) When fish produce too much acid. C) When toxic waste is dumped directly into the sea.

7. Why is ocean acidification a major problem?

A) It turns the water a bright green color. B) It makes the water too hot to swim in. C) It severely damages coral reefs and marine life that rely on calcium carbonate shells.

9. What is a ’tipping point’ in the context of climate change?

A) The point where all politicians agree on a solution. B) The highest temperature recorded in a year. C) A critical threshold that, when crossed, leads to irreversible and drastic changes in the climate system.

10. What is the ultimate message regarding solving the climate crisis?

A) Only planting trees can solve the entire problem. B) We must rapidly transition to renewable energy sources and drastically cut emissions worldwide. C) It is too late to do anything, so we should give up.
