Slide 1 : Why Global warming ?
Slide 2 : 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.
Slide 3 : 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”?
Slide 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.
Slide 7 : Effects of Global Warming Increased Temperature Habitat Damage and Species Affected Changes in Water Supply Rising Sea Level
Slide 8 : What’s the proof that global warming is taking place?
Slide 9 : Portage Glacier 1914 2004 Alaska
Slide 10 : Colorado River Arizona June 2002 Dec 2003
Slide 11 : Why is global warming happening?
Slide :
Slide 13 : When did global warming start?
Slide 14 : Global Warming graph
Slide 15 : How is global warming measured?
Slide 16 : Ice Core Data CO2 Measurements Before 1958 - Antarctica
Slide 17 : CO2 Atmospheric Measurements CO2 Measurements Since 1958 – Mauna Loa, Hawaii
Slide 18 : Temperature (Northern Hemisphere) CO2 Concentrations 1000 Years of CO2 and Global Warming Degree Celsius Increase Parts Per Million Year Year
Slide 19 : 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
Slide 22 : What’s being done now to reduce our emissions? Solar Power Wind Power Fuel-Efficiency
Slide 23 : We can stop global warming!
Slide 24 : What can you do to help solve the problem?
Slide 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.
Slide 26 : Be Bulb Smart—Use CFLs Incandescent Compact Fluorescent 500 lbs. of coal What’s the difference? 1,430 lbs. CO2 pollution avoided $30 saved
Slide 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.
Slide 28 : Thank you
