Understanding Climate Change

The video explores the existence and nature of climate change, distinguishing between climate and weather. It delves into natural causes like sunspots and Milankovitch cycles, and explains the role of greenhouse gases. The human impact on climate change, particularly through industrialization and CO2 emissions, is discussed. Finally, it highlights efforts to combat climate change, including global agreements and the rise of renewable energy.

What is the primary difference between climate and weather?

• Climate refers to short-term atmospheric conditions, while weather is long-term.

• Climate and weather are the same.

• Weather refers to short-term atmospheric conditions, while climate is long-term.

• Weather is a global phenomenon, while climate is local.

Which natural phenomenon is associated with changes in solar activity?

• Milankovitch cycles

• Sunspots

• Volcanic eruptions

• Ocean currents

What are Milankovitch cycles?

• Variations in Earth's orbit and axis over thousands of years

• Changes in solar radiation due to sunspots

• Oceanic temperature fluctuations

• Short-term weather patterns

Which of the following is NOT a greenhouse gas?

• Methane

• Carbon dioxide

• Water vapor

• Oxygen

How do greenhouse gases affect Earth's temperature?

• They have no effect on temperature.

• They cool the Earth's surface.

• They trap heat in the atmosphere.

• They reflect sunlight away from Earth.

What has significantly increased the levels of CO2 and methane in the atmosphere?

• Industrial activities since the Industrial Revolution

• Volcanic eruptions

• Solar flares

• Natural forest fires

What is one visible effect of climate change?

• Increased polar ice caps

• Decreased sea levels

• Expansion of desert areas

• Stabilized global temperatures

Why is the human-induced climate change often not taken seriously?

• Insufficient media coverage

• Lack of scientific evidence

• Natural climate cycles

• Economic interests

What is one global effort to combat climate change?

• Banning renewable energy

• Reducing greenhouse gas emissions

• Promoting deforestation

• Increasing fossil fuel usage

What role do renewable energies play in addressing climate change?

• They are more expensive than fossil fuels.

• They help reduce reliance on fossil fuels.

• They increase greenhouse gas emissions.

• They have no impact on climate change.
