Question 1: Global Warming: The long-term increase in Earth's average surface temperature due to greenhouse gas emissions.

Answer: The sustained rise in Earth's surface temperature caused by greenhouse gases.

Question 2: Greenhouse Effect: The process by which greenhouse gases trap heat in the Earth's atmosphere.

Answer: The natural process where greenhouse gases trap heat, warming the planet.

Question 3: Fossil Fuels: Natural fuels formed from the remains of ancient plants and animals, such as coal, oil, and natural gas.

Answer: Coal, oil, and natural gas used as energy sources, releasing greenhouse gases when burned.

Question 4: Carbon Footprint: The total amount of greenhouse gases emitted directly or indirectly by an individual, organization, or country.

Answer: The total greenhouse gases produced by a person or entity.

Question 5: Mitigation: Strategies aimed at reducing or preventing the emission of greenhouse gases.

Answer: Actions taken to reduce greenhouse gas emissions and limit climate change.

Question 1: What is the main cause of increased global temperatures over the last century?

Answer: Burning fossil fuels

Question 2: Name one major greenhouse gas responsible for Climate Change.

Answer: Carbon dioxide (CO2)

Question 3: Which region is most vulnerable to rising sea levels?

Answer: Bangladesh

Question 4: Explain the greenhouse effect in your own words.

Answer: Greenhouse gases trap heat in the atmosphere, warming the Earth, similar to a blanket keeping you warm.

Question 5: Identify two human activities that contribute to Climate Change.

Answer: Burning fossil fuels and deforestation.

Question 1: Describe how rising sea levels in Bangladesh threaten its coastal communities.

Answer: Rising sea levels cause flooding, erosion, and displacement of communities, threatening livelihoods and infrastructure.

Question 2: What are two strategies Bangladesh is implementing to adapt to these challenges?

Answer: Building sea walls and relocating vulnerable communities.

Question 3: Analyze how these adaptation strategies can reduce the impacts of climate change in Bangladesh.

Answer: These strategies help prevent flooding, protect homes and agriculture, and reduce displacement, but require significant investment and ongoing maintenance.

Question 4: Evaluate the effectiveness of Bangladesh’s adaptation efforts in the context of global climate change mitigation.

Answer: While adaptation measures in Bangladesh are crucial for immediate risk reduction, they are limited without broader global efforts to reduce greenhouse gas emissions. Long-term success depends on international cooperation and sustainable development.

Question 1: Explain why deforestation in the Amazon rainforest contributes to Climate Change.

Answer: Deforestation reduces the number of trees that absorb CO2, increasing greenhouse gases in the atmosphere and contributing to global warming.

Question 2: Analyze the causes of increased frequency and intensity of wildfires in Australia.

Answer: Higher temperatures, prolonged droughts, and dry conditions due to climate change create ideal conditions for wildfires, which are further exacerbated by human activities.

Question 3: Explain the role of melting polar ice caps in global sea level rise.

Answer: Melting ice caps add freshwater to oceans, increasing sea levels and threatening coastal areas worldwide.

Question 1: To what extent are renewable energy sources effective in reducing greenhouse gas emissions and combating Climate Change?

Answer: Renewable energy sources like wind, solar, and hydro significantly reduce greenhouse gas emissions compared to fossil fuels, making them vital for mitigation. However, challenges such as high initial costs, technology limitations, and grid integration can hinder their widespread adoption. Their effectiveness depends on policy support, technological advancements, and global cooperation. Overall, while not a complete solution alone, renewables are essential in reducing the carbon footprint and mitigating Climate Change impacts.

Question 2: Evaluate the success of international agreements, like the Paris Agreement, in addressing Climate Change.

Answer: The Paris Agreement represents a significant global effort to limit temperature rise and reduce emissions through nationally determined contributions. Its success depends on countries’ commitment and implementation. While it has increased awareness and set important targets, actual progress has been mixed, with some nations falling short. Continued international cooperation, transparency, and enforcement are necessary for its long-term effectiveness. Overall, it has been a positive step but requires stronger action and accountability to effectively combat Climate Change.
