Understanding Climate Change

The video discusses the rapid changes in climate patterns due to human activities, highlighting the increase in global temperatures and the absorption of heat by oceans. It explains how burning fossil fuels contributes to greenhouse gas emissions, leading to global warming. The video also outlines the severe consequences of climate change, such as extreme weather events and rising sea levels. Finally, it suggests practical steps for sustainable living to mitigate climate change effects.

What has been observed about winter and summer weather patterns in recent years?

• There is no change in winter and summer patterns.

• Both winters and summers are becoming milder.

• Winters are milder and summers are extremely hot.

• Winters are getting colder and summers milder.

What does the term 'climate' refer to?

• Short-term weather changes in a specific area.

• Daily temperature variations.

• Long-term weather patterns of a specific area.

• Immediate weather conditions.

How do human activities primarily contribute to climate change?

• By using renewable energy sources.

• By increasing the use of non-renewable energy sources.

• By planting more trees.

• By reducing greenhouse gas emissions.

What is the effect of burning fossil fuels on the atmosphere?

• It increases greenhouse gases, trapping heat.

• It has no effect on the atmosphere.

• It cools down the planet.

• It reduces the amount of greenhouse gases.

What analogy is used to describe the effect of trapped heat on Earth?

• A cold winter night.

• A cool breeze on a summer day.

• A refreshing rain shower.

• A permanent fever or being in a hot car.

Which gases are primarily responsible for trapping solar energy?

• Argon and neon.

• Hydrogen and helium.

• Carbon dioxide, methane, and nitrous oxide.

• Oxygen and nitrogen.

What are some consequences of climate change mentioned in the video?

• Decreased sea levels and fewer storms.

• Stable weather patterns and reduced flooding.

• Increased heat waves, droughts, and rising sea levels.

• More snowfall and cooler summers.

What is one way to reduce energy consumption at home or school?

• Leave devices plugged in.

• Unplug and unpower devices.

• Increase the use of air conditioning.

• Use more non-renewable energy.

How can planting trees help combat climate change?

• By reducing oxygen levels.

• By absorbing carbon dioxide.

• By providing shade only.

• By increasing carbon emissions.

What is the '3 Rs' approach to sustainability?

• Reuse, Reduce, Recycle.

• Recycle, Reuse, Replant.

• Rebuild, Replant, Reuse.

• Reduce, Reuse, Rebuild.
