  1. 1. Vivek Srivastava
  2. 2. What is global warming?
  3. 3. How Global Warming Works Carbon Dioxide (CO2) Fossil fuels (coal, oil, natural gas)
  4. 4. 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.
  5. 5. What’s the difference between “global warming” and “climate change”?
  6. 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. 7. Effects of Global Warming Rising Sea Level Habitat Damage and Increased Temperature Changes in Water Supply
  8. 8. What’s the proof that global warming is taking place?

  22. 22. What’s being done now to reduce our emissions? Wind Power Solar Power Fuel-Efficiency
  23. 23. What can you do to help solve the problem?
  24. 24. 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.
  25. 25. Be Bulb Smart—Use CFLs Incandescent What’s the difference? Compact Fluorescent 500 lbs. of coal •1,430 lbs. CO2 pollution avoided •$30 saved
  26. 26. 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.
