Understanding Climate Change

The video explains Earth's warming by comparing it to a greenhouse. Energy from the sun enters the atmosphere, heating the planet. Previously, heat escaped back into space, maintaining a stable temperature. However, increased carbon dioxide emissions have thickened the 'glass' of the greenhouse, trapping more heat and causing temperatures to rise. This results in a planet that is becoming too hot for comfort and survival. The video concludes with a call to take action against climate change.

How does the Earth's atmosphere function in relation to solar energy?

• It allows some energy to pass through while reflecting some.

• It absorbs all solar energy completely.

• It reflects all solar energy back into space.

• It blocks all solar energy from entering.

What change did human activities bring to the Earth's greenhouse effect?

• They made the atmosphere thinner.

• They reduced the amount of carbon dioxide.

• They increased the thickness of the greenhouse 'glass'.

• They stopped solar energy from entering.

What is the primary consequence of thicker greenhouse 'glass'?

• The Earth receives less solar energy.

• The Earth cools down rapidly.

• Heat escapes into space more slowly.

• Heat escapes into space more quickly.

What continues to happen despite the thickening of the greenhouse 'glass'?

• The Earth receives less solar energy.

• The Earth stops receiving solar energy.

• Solar energy is completely blocked.

• Solar energy continues to stream in at the same rate.

What is the eventual result of the current trend in global temperatures?

• A planet with no temperature change.

• A planet too hot for comfortable living.

• A planet with stable temperatures.

• A more habitable planet.
