Which is more dangerous melting of a glacier in Alaska or melting of an iceberg in Antarctica? Why? 40. List as many effects of sea level change as you can. 41. What 2 different things can cause sea level to increase? End

3. CLIMATE CHANGE EFFECTS… SEA TEMPERATURE Why do they change? Past 100 years… Physical impact Thermal expansion Stronger storms Ecosystem damage Coral Bleaching Disease Reef die-off Krill Base of food chain Invasive species and disease Increased competition Drive native species to extinction

4. …OCEAN ACIDIFICATION Caused by CO 2 not climate change Ocean is largest CO 2 sink CO 2 + water = carbonic acid Also decreases calcium carbonate What has happened? Prediction Consequences Less calcium carbonate to build shells Reef system collapse

5. …ECOSYSTEM DAMAGE Shift/change growing seasons Increase allergies Change migration patterns Stress native species Increased disease Invasive species
