Sea Level Rise: Causes, Impacts, and Mitigation Strategies for AP Exam

📚 Quick Study Guide

• 🌍 Causes of Sea Level Rise: Thermal expansion of water, melting glaciers and ice sheets.
• 🌡️ Thermal Expansion: Water expands as it warms. This is a direct result of increased global temperatures due to greenhouse gas emissions.
• 🧊 Melting Ice: Melting land ice (glaciers, ice sheets) adds water to the ocean. Melting sea ice does *not* directly contribute to sea level rise (think Archimedes' principle!), but it does reduce albedo, leading to further warming.
• 📉 Impacts: Coastal flooding, erosion, saltwater intrusion into freshwater sources, habitat loss.
• 🏘️ Vulnerable Areas: Low-lying coastal areas, island nations.
• 🛡️ Mitigation Strategies: Reducing greenhouse gas emissions (renewable energy, energy efficiency), building coastal defenses (sea walls, levees), restoring coastal habitats (mangroves, salt marshes).
• 📊 Important Formulas/Concepts: Understanding the relationship between temperature and volume (thermal expansion), albedo, greenhouse effect, and the impacts on coastal ecosystems.
• 🗓️ IPCC Reports: The Intergovernmental Panel on Climate Change (IPCC) provides comprehensive assessments of climate change, including sea level rise projections. Familiarize yourself with their key findings.
