TED-ED: Climate change: Earth's giant game of Tetris - Joss Fong

The video explains the carbon cycle, where carbon enters and exits the atmosphere, and its crucial role in sustaining life on Earth. It highlights how carbon dioxide acts as a greenhouse gas, trapping heat and affecting climate stability. The industrial revolution introduced more carbon into the atmosphere through fossil fuels, intensifying the greenhouse effect and leading to climate change. This results in rising sea levels, disrupted ecosystems, and extreme weather, emphasizing the urgent need for action.

What is the primary role of carbon dioxide in Earth's atmosphere?

• It traps heat from the sun.

• It absorbs harmful UV rays.

• It acts as a coolant.

• It reflects sunlight back into space.

How did human activities begin to alter the carbon cycle approximately 200 years ago?

• By reducing oceanic absorption.

• By burning fossil fuels.

• By planting more trees.

• By increasing volcanic activity.

What is one major consequence of the increased greenhouse effect?

• Decreased global temperatures.

• Stabilization of sea levels.

• Melting of polar ice caps.

• Increased volcanic eruptions.

What happens to the Earth's ability to reflect sunlight as polar ice caps melt?

• It fluctuates randomly.

• It decreases.

• It remains unchanged.

• It increases.

How does climate change affect different regions and populations?

• It has no impact on coastal areas.

• It affects all regions equally.

• It only impacts urban areas.

• It affects different regions in varying ways.
