Climate Change and Its Causes

The video discusses the causes of global warming, emphasizing the role of human activities like burning fossil fuels. It explains the greenhouse effect and debunks misconceptions about unrelated correlations. The video examines solar activity and Earth's movements, concluding they are not responsible for current climate changes. It highlights the evidence of human impact through carbon isotopes and stresses the importance of taking action to mitigate climate change, suggesting a transition to renewable energy.

What has been the primary human activity linked to the rise in Earth's temperature over the past 150 years?

• Burning fossil fuels

• Urbanization

• Deforestation

• Agriculture

Why is it important to distinguish between correlation and causation in climate studies?

• To measure the speed of climate change

• To understand if two events are directly related

• To determine the exact amount of carbon dioxide

• To identify the exact temperature of the Earth

Which natural factor is NOT considered a primary cause of the current rapid climate change?

• Solar activity

• Earth's orbital changes

• Volcanic eruptions

• Human industrial activity

What is the primary function of greenhouse gases in Earth's atmosphere?

• To reflect sunlight back into space

• To absorb and trap heat

• To increase the Earth's rotation speed

• To cool down the Earth's surface

How do scientists use carbon isotopes to determine the source of carbon dioxide in the atmosphere?

• By observing the color of the sky

• By counting the number of carbon atoms

• By analyzing the ratio of carbon isotopes

• By measuring the temperature of the air

What is the significance of the absence of carbon-14 in atmospheric carbon dioxide?

• It indicates recent volcanic activity

• It suggests the carbon comes from ancient sources

• It shows the presence of living plants

• It proves the existence of cosmic rays

What is the potential consequence of ignoring our role in climate change?

• Severe impacts on our lifestyle

• An increase in renewable energy sources

• A reduction in fossil fuel consumption

• A decrease in global temperatures

What is one benefit of taking action against climate change?

• More frequent natural disasters

• Increased fossil fuel usage

• Higher global temperatures

• Development of renewable technologies

What is the main argument for transitioning to renewable energy sources?

• Renewables increase pollution

• Fossil fuels will eventually run out

• Fossil fuels are infinite

• Renewables are less efficient

What is the ultimate question posed to the audience regarding climate change action?

• Can technology solve climate change?

• Is climate change a natural process?

• Should we take action or do nothing?

• Should we wait for more evidence?
