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?

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)

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

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

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

CO2 Molecules Absorb Heat

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

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.

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.

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

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?

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

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.
