  1. Do Now 4.24 Objectives: 1.Describe the causes, effects, and solutions to global climate change. 2. Define greenhouse effect, and describe how humans are increasing it on Earth. Task: What do you think? What is global climate change (aka global warming) and what is it caused by?

  2. Global Climate Change (GCC): What it is • The Earth is warming, and there are many associated changes occurring in Earth’s systems. • Note: climate = long term weather patterns (15+ years)

  3. Causes of Global Climate Change • Global climate change is caused by an increase in the greenhouse effect.

  4. Greenhouse Effect: Goldilocks Earth • Without any greenhouse effect, Earth would be VERY cold, like Mars. • Too much greenhouse effect can cause temperatures to rise. Earth Mars Venus

  5. So What’s Increasing the Greenhouse Effect? • CO2 Emissions from combustion of fossil fuels are the largest factor

  6. CO2 Molecules Absorb Heat

  7. CO2 Is Produced by Burning Fossil Fuels • Methane and nitrous oxides are also greenhouse gasses produced by industrial processes.

  8. RECAP: Causes of Global Climate Change • Earth’s climate (long-term weather pattern) is changing. Global average temperatures are going up. • Carbon dioxide (CO2) is produced by burning fossil fuels. • CO2 and other greenhouse gasses absorb heat radiated by Earth.

  9. Effects of Global Climate Change (GCC) • As we watch the film, make a list of all of the effects of global climate change that are mentioned.

  10. Effects on Populations and Ecosystems • How will the effects described affect organisms on Earth?

  11. Effects Here In Charm City • You have two minutes to work with a partner sitting next to you. • What effect do you think will hit Baltimore City the hardest? • What can Baltimore do to adapt to that problem?

  12. Solutions: The Future Is Ours • Americans have more ability to reduce emissions than anyone else! We each have an important responsibility.

  13. Solutions: What Can YOU do? • Watch the video and record anything you can do TODAY. • Your homework? Syllabus change: DO SOMETHING that cuts CO2 emissions – anything – then write a brief paragraph: • What you did • How it cut CO2 emissions • If you can keep it up / why.
