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 Slide 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 Slide 5: 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 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 When did global warming start? : When did global warming start? Slide 14: Global Warming graph How is global warming measured? : How is global warming measured? Slide 16: Ice Core Data CO2 Measurements Before 1958 - Antarctica CO2 Atmospheric Measurements : CO2 Atmospheric Measurements CO2 Measurements Since 1958 – Mauna Loa, Hawaii 1000 Years of CO2 and Global Warming : Temperature (Northern Hemisphere) CO2 Concentrations 1000 Years of CO2 and Global Warming Degree Celsius Increase Parts Per Million Year Year Global Warming: Shifting Gears : Global Warming: Shifting Gears Slide 20: U.S. emission Slide 21: 2007 Reductions in CO2 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! Slide 24: 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. CO2 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. Slide 28: Thank you You do not have the permission to view this presentation. In order to view it, please contact the author of the presentation.
