PowerPoint Presentation: Why Global warming ? What is global warming?: What is global warming? The changes in the surface air temperature, referred to as the global temperature, brought about by the enhanced greenhouse effect, which is induced by emissions of greenhouse gases into the air. How Global Warming Works: How Global Warming Works Fossil fuels (coal, oil, natural gas) Carbon Dioxide (CO 2 ) PowerPoint Presentation: 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. Example of the Greenhouse Effect PowerPoint Presentation: What’s the difference between “global warming” and “climate change”? Difference: Difference GLOBAL WARMING 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. Effects of Global Warming: Effects of Global Warming Increased Temperature Habitat Damage and Species Affected Changes in Water Supply Rising Sea Level What’s the proof that global warming is taking place?: What’s the proof that global warming is taking place? Portage Glacier: Portage Glacier 1914 2004 Alaska Colorado River: Colorado River Arizona June 2002 Dec 2003 Why is global warming happening? : Why is global warming happening? Burning of Fossil Fuels: 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 When did global warming start?: When did global warming start? PowerPoint Presentation: Global Warming graph How is global warming measured?: How is global warming measured? PowerPoint Presentation: Ice Core Data CO 2 Measurements Before 1958 - Antarctica CO2 Atmospheric Measurements: CO 2 Atmospheric Measurements CO 2 Measurements Since 1958 – Mauna Loa, Hawaii 1000 Years of CO2 and Global Warming : Temperature (Northern Hemisphere) CO 2 Concentrations 1000 Years of CO 2 and Global Warming Degree Celsius Increase Parts Per Million Year Year Global Warming: Shifting Gears: Global Warming: Shifting Gears PowerPoint Presentation: U.S. emission PowerPoint Presentation: 2007 Reductions in CO 2 Per Year Gigaton Carbon Billions of Metric Tons Carbon Our Goal What’s being done now to reduce our emissions?: What’s being done now to reduce our emissions? Solar Power Wind Power Fuel-Efficiency We can stop global warming!: We can stop global warming! PowerPoint Presentation: What can you do to help solve the problem? Simple Things To Do: 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. Be Bulb Smart—Use CFLs: Be Bulb Smart—Use CFLs Incandescent Compact Fluorescent 500 lbs. of coal What’s the difference? 1,430 lbs. CO 2 pollution avoided $30 saved Simple Things To Do: 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. PowerPoint Presentation: Thank you
