Climate Change: Effects and Impact

(Video) watch the "Eyes of Nye Climate Change" video and answer the following: 1. Why are ice cores used to study ancient climate? 2. How do CO2 and Temperature graphs compare? (sketch) 3. Why is a rapid rise in temperature dangerous? 4. What can you do to help?

Video Discussion 1. Why are ice cores used to study ancient climate? 2. How do CO2 and Temperature graphs compare? (sketch)

Video Discussion 3. Why is a rapid rise in temperature dangerous? 4. What can you do to help?

Aquatic Ecosystems (p.204) Use your textbook (p.204) to summarize (maximum of one or two sentences) the effects of: Melting Sea Ice: New Food Chains: Warmer Oceans: Rising Sea Levels: More Violent Storms: 5min We'll watch the video first, it'll help. Then break into 5 groups, you'll be assigned one of those 5 topics, and you'll work with your group members to make a summary of that topic from the textbook. Each group will present and I will randomly choose one student from each group to present their groups summary.

Aquatic Ecosystems Use your textbook (p.204) to summarize the effects of: Melting Sea Ice: loss of sea life threatens existing species (e.g. polar bears) and ways of life (e.g. Inuit) New Food Chains: loss of krill changes where organisms eat which changes old areas and new areas Warmer Oceans: destruction of coral reef (habitat loss) slowing of ocean currents changes weather/climate Rising Sea Levels: flooding of low lying areas (habitat loss) More Violent Storms: warm water gives more energy to storms = more powerful hurricanes

Terrestrial Ecosystems (p.206) Use your textbook (p.206) to summarize the effects of: Changing Organisms: Melting Land Ice: New Deserts: More Flooding Human Health Same groups and we're doing the same thing as before! 6min

Terrestrial Ecosytems (p.206) Changing Organisms: migratory animals may change migration times and patterns. Others can't adapt and may die Melting Land Ice: loss of glaciers (freshwater) and permafrost (changing landscape - collapsing forests) New Deserts: loss of drinking water and farm land (food) More Flooding: heavy rainfall and rising sea levels affect low lying areas (habitat loss) Human Health: migrating species introduce new illnesses (e.g. West Nile) diseases thrive in warm, wet conditions

Positive and Negative Impacts (p.208-209) use figure 3.6 on p.208-209 to answer Learning Check p.209 #1,2,3
