Climate Change Quiz

Climate Change

Definition

• Climate change refers to the long-term warming of the planet, which is primarily caused by the increasing levels of greenhouse gases in the Earth's atmosphere.
• These gases, such as carbon dioxide and methane, trap heat from the sun, leading to a rise in global temperatures.

Causes

• Greenhouse gases: The main cause of climate change, primarily due to human activities such as:
  • Burning fossil fuels (coal, oil, and gas)
  • Deforestation and land-use changes
  • Agriculture and livestock production
• Natural factors: Volcanic eruptions, changes in Earth's orbit, and variations in the sun's energy output also contribute to climate change, but to a lesser extent.

Effects

• Rising global temperatures: Average global temperature has risen by about 1°C since the late 1800s.
• Extreme weather events: Increased frequency and severity of heatwaves, droughts, floods, and storms.
• Sea-level rise: Thawing of polar ice caps and glaciers, leading to coastal erosion and flooding.
• Impacts on ecosystems: Changes in species distribution, extinction, and disruption of food chains.
• Human health: Increased risk of heat-related illnesses, respiratory problems, and the spread of disease.

Consequences

• Economic impacts: Damage to infrastructure, loss of productivity, and increased costs for healthcare and emergency response.
• Food and water security: Changes in crop yields, water scarcity, and decreased food quality.
• Social and cultural impacts: Displacement of communities, loss of cultural heritage, and increased migration.

Mitigation and Adaptation Strategies

• Reduce greenhouse gas emissions: Transition to renewable energy sources, increase energy efficiency, and implement carbon capture and storage.
• Adaptation measures: Develop early warning systems, implement climate-resilient infrastructure, and promote sustainable agriculture practices.
• International cooperation: Global agreements, such as the Paris Agreement, aim to limit global warming to well below 2°C and pursue efforts to limit it to 1.5°C.
