    2 : What is global warming?
    3 : How Global Warming Works
    4 : 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
    5 : What’s the difference between “global warming” and “climate change”?
    6 : 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.
    7 : Effects of Global Warming Increased Temperature Habitat Damage and Species Affected Changes in Water Supply Rising Sea Level
    8 : What’s the proof that global warming is taking place?
    9 : Portage Glacier 1914 2004 Alaska Photos: NOAA Photo Collection and Gary Braasch –
    10 : Colorado River Arizona June 2002 Dec 2003
    11 : Why is global warming happening?
    12 : 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
    13 : When did global warming start?
    14 : Global Atmospheric Concentration of CO2
    15 : How is global warming measured?
    16 : Ice Core Data CO2 Measurements Before 1958 - Antarctica
    17 : CO2 Atmospheric Measurements CO2 Measurements Since 1958 – Mauna Loa, Hawaii
    18 : 1000 Years of CO2 and Global Warming Degree Celsius Increase Parts Per Million Year Year 1000 1200 1400 1600 1800 2000 1000 1200 1400 1600 1800 2000
    19 : Global Warming: Shifting Gears
    20 : 2007 Goal: Reductions in CO2 Per Year Billions of Metric Tons Carbon
    21 : 2007 Reductions in CO2 Per Year Gigaton Carbon Produce electricity efficiently Use electricity efficiently Vehicle efficiency Solar and Wind Power Biofuels Carbon capture and storage Billions of Metric Tons Carbon Our Goal
    22 : What’s being done now to reduce our emissions? Solar Power Wind Power Fuel-Efficiency
    23 : We can stop global warming!
    24 : What can you do to help solve the problem?
    25 : 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.
    26 : Be Bulb Smart—Use CFLs Incandescent Compact Fluorescent What’s the difference? 1,430 lbs. CO2 pollution avoided $30 saved
    27 : 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.
