Unit 2361: Climate Change – Causes, Impacts, and Responses

1. Introduction to Climate Change

• Definition and key concepts
• Causes of climate change: natural vs. anthropogenic
• Difference between climate change and global warming
• Historical perspective and timeline of climate change awareness

2. Greenhouse Effect and Global Warming

• The greenhouse effect explained
• Major greenhouse gases and their sources
• Human activities contributing to increased emissions (e.g., fossil fuels, deforestation)
• Feedback loops and amplifying factors

3. Climate Change Evidence

• Rising global average temperatures: data and trends
• Melting ice caps, glaciers, and Arctic sea ice decline
• Changes in precipitation patterns and extreme weather events
• Ocean warming and acidification
• Scientific monitoring methods and climate models

4. Impacts of Climate Change

• Effects on ecosystems and biodiversity
• Increased frequency and severity of weather events (storms, droughts, floods)
• Rising sea levels and coastal impacts
• Human health risks (heat stress, vector-borne diseases)
• Socioeconomic consequences and impacts on livelihoods

5. Mitigation Strategies

• Reducing greenhouse gas emissions: renewable energy, energy efficiency
• Carbon capture and storage technologies
• Sustainable land use and reforestation
• Policy instruments: carbon pricing, emissions trading
• Role of individuals, businesses, and governments

6. Adaptation to Climate Change

• Concept and importance of adaptation
• Community-level adaptation measures
• Infrastructure resilience and disaster risk management
• Agricultural adaptation strategies
• Role of governments and international support

7. International Agreements and Policies

• Overview of major climate agreements: Kyoto Protocol, Paris Agreement
• Mechanisms for international cooperation and commitments
• Nationally Determined Contributions (NDCs)
• Challenges in global climate governance

8. Climate Change Communication

• Importance of effective communication in climate action
• Role of media, education, and advocacy
• Addressing misinformation and climate skepticism
• Strategies for engaging diverse audiences

9. Climate Change and Social Justice

• Unequal impacts on vulnerable and marginalized populations
• Intersection of climate change with poverty, race, and gender
• Environmental justice and equity considerations
• Case studies of climate justice movements

10. Future Scenarios and Projections

• Climate models and emission scenarios (e.g., RCPs)
• Potential future impacts based on current trends
• Tipping points and irreversible changes
• Pathways to sustainable futures
• Role of innovation and global cooperation
