Climate change and the enhanced greenhouse effect

The video tutorial explains how burning fossil fuels increases carbon dioxide in the atmosphere, leading to climate change. It covers the chemical process of burning fossil fuels, historical CO2 levels, and the greenhouse effect. Misconceptions about the carbon cycle are addressed, and the consequences of climate change, such as extreme weather and rising temperatures, are discussed.

What are fossil fuels primarily composed of?

• Water and carbon dioxide

• Carbon and hydrogen

• Oxygen and nitrogen

• Nitrogen and hydrogen

How much higher are current carbon dioxide levels compared to pre-industrial times?

• 50% higher

• 20% higher

• 70% higher

• 30% higher

What analogy is used to describe the effect of added carbon dioxide on Earth's atmosphere?

• A hat on the planet

• A shield over the Earth

• A sweater around the planet

• A blanket around the Earth

Why doesn't burning wood contribute to the enhanced greenhouse effect?

• Because it is not a fossil fuel

• Because it releases no carbon dioxide

• Because the carbon is part of the natural cycle

• Because it releases only oxygen

What are some consequences of increased energy trapped on Earth?

• Decreased global temperatures

• Melting glaciers and extreme weather

• Increased oxygen levels

• More stable weather patterns
