Question 1: Define 'greenhouse gases' and give two examples.

Answer: Greenhouse gases are gases like carbon dioxide and methane that trap heat in the Earth's atmosphere, leading to global warming.

Question 2: What is 'fossil fuel combustion'?

Answer: Fossil fuel combustion is the process of burning coal, oil, or natural gas to produce energy, which releases greenhouse gases.

Question 3: Explain 'climate change adaptation' with an example.

Answer: Climate change adaptation involves adjusting practices to reduce vulnerability, such as building flood defenses in coastal areas like Brighton.

Question 4: Define 'carbon footprint' and why it matters.

Answer: A carbon footprint is the total amount of greenhouse gases emitted directly or indirectly by an individual, organization, or country; reducing it helps mitigate climate change.

Question 1: What is the primary greenhouse gas responsible for global warming?

Answer: Carbon dioxide

Question 2: Name two natural processes that contribute to climate change.

Answer: Volcanic eruptions and changes in solar radiation.

Question 3: Identify three human activities that increase greenhouse gas emissions.

Answer: Burning fossil fuels, deforestation, and industrial processes.

Question 4: Which country is the largest emitter of carbon dioxide currently?

Answer: China

Question 1: Based on the case study of the UK, describe two ways Climate Change has affected weather patterns in cities like London.

Answer: Climate Change has led to more frequent heatwaves and increased rainfall, causing flooding in London.

Question 2: In the Maldives, rising sea levels threaten low-lying islands. Explain how this impacts local communities and ecosystems.

Answer: Rising sea levels cause flooding, loss of land, and damage to coral reefs, threatening homes, livelihoods, and biodiversity.

Question 3: Using the case of Australia, explain how wildfires are linked to Climate Change.

Answer: Higher temperatures and prolonged droughts due to Climate Change increase the frequency and severity of wildfires in Australia.

Question 4: Discuss the global impact of melting Arctic ice on sea levels and weather systems.

Answer: Melting Arctic ice contributes to rising sea levels worldwide and disrupts weather patterns, leading to more severe storms and changing climates.

Question 1: Explain why burning fossil fuels increases greenhouse gases and contributes to global warming.

Answer: Burning fossil fuels releases carbon dioxide, a greenhouse gas, into the atmosphere. This traps heat and enhances the greenhouse effect, leading to global warming.

Question 2: Analyse the reasons for the increasing frequency of extreme weather events in recent decades.

Answer: The increase is due to higher global temperatures caused by greenhouse gas emissions, which lead to more intense storms, heatwaves, and flooding.

Question 3: Describe the pattern of global temperature rise over the last century and its relation to industrial development.

Answer: Global temperatures have steadily increased since the early 20th century, correlating with industrial growth and increased fossil fuel use, intensifying the greenhouse effect.

Question 1: To what extent are renewable energy sources effective in reducing greenhouse gas emissions? Consider economic, environmental, and social factors in your answer. (8-12 marks)

Answer: Renewable energy sources like wind, solar, and hydro are highly effective in reducing greenhouse gases because they produce clean energy with minimal emissions. Economically, they can be cost-competitive in the long term, though initial setup costs are high. Environmentally, they reduce reliance on fossil fuels and decrease air pollution. Socially, they create jobs and promote sustainable development. However, challenges include intermittency, storage issues, and the need for infrastructure investment. Overall, while not a complete solution alone, renewables are vital in strategies to combat Climate Change, especially when combined with energy efficiency and policy measures.
