1 What is happening? What can we do about it?
GLOBAL WARMING What is happening? What can we do about it?

2 Entrance Questions (Done in notebook)
a. What does global warming mean? b. What causes global warming? How does carbon dioxide emission affect global warming? Do Now: Write at least two questions about the diagram/picture.

3

4 What exactly is the atmosphere?

5 What is Global Warming? A gradual increase in the overall temperature of the earth's atmosphere because of the greenhouse effect. The greenhouse effect is caused by increased levels of carbon dioxide, and other pollutants. What does that mean?????

6 How Global Warming Works
Carbon Dioxide (CO2) Fossil fuels (coal, oil, natural gas)

7 Example of the Greenhouse Effect
The Sun’s energy passes through the car’s windshield. This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.

8 What’s the difference between “global warming” and “climate change”?

9 Global Warming vs. Climate Change
is the increase of the Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere. CLIMATE CHANGE is a broader term that refers to long-term changes in climate, including average temperature and precipitation.

10 Effects of Global Warming
Rising Sea Level Increased Temperature Habitat Damage and Species Affected Changes in Water Supply

11 What’s the proof that global warming is taking place?

14 What makes Global Warming Happen? Burning of Fossil Fuels
Pollution from coal, natural gas, and oil Pollution from coal, natural gas, and oil Pollution from coal, natural gas, and oil

15 When did global warming start?
What do you notice about the data on this chart?

16 Global Atmospheric Concentration of CO2

17 How is global warming measured?

18 CO2 Measurements Before 1958 - Antarctica
Ice Core Data CO2 Measurements Before Antarctica

19 CO2 Atmospheric Measurements
CO2 Measurements Since 1958 – Mauna Loa, Hawaii

20 1000 Years of CO2 and Global Warming
Temperature (Northern Hemisphere) CO2 Concentrations Degree Celsius Increase Parts Per Million 1000 1200 1400 1600 1800 2000 1000 1200 1400 1600 1800 2000 Year Year

21 Global Warming: Shifting Gears
Can it be stopped?

22 Billions of Metric Tons Carbon
Goal: Reductions in CO2 Per Year 2007

23 Billions of Metric Tons Carbon
Our Goal Billions of Metric Tons Carbon Produce electricity efficiently Use electricity efficiently Vehicle efficiency Solar and Wind Power Biofuels Carbon capture and storage Gigaton Carbon Reductions in CO2 Per Year 2007

24 What’s being done now to reduce our emissions?
Wind Power Solar Power Fuel-Efficiency

25 We can stop global warming!
Scientists agree that the burning of fossil fuels is causing global warming. Since these fuels are burned for energy, and everyone uses energy, everyone can help stop global warming just by using less energy or energy from renewable sources!

26 What can you do to help solve the problem?

27 Simple Things To Do Turn off your computer or the TV
when you’re not using it. Take shorter showers. Heating water uses energy. Keep rooms cool by closing the blinds, shades, or curtains. Turn off the lights when you leave a room. Use compact fluorescent bulbs.

28 Be Bulb Smart—Use CFLs What’s the difference? Compact Fluorescent
Incandescent 500 lbs. of coal 1,430 lbs. CO2 pollution avoided $30 saved

29 Simple Things To Do Dress lightly when it’s hot instead of turning up
the air conditioning. Or use a fan. Dress warmly when it’s cold instead of turning up the heat. Offer to help your parents keep the air filters on your AC and furnace clean. Walk short distances instead of asking for a ride in the car. Plant a tree. Recycle.
