2. What is global warming? 3. How Global Warming WorksCarbon Dioxide (CO2)Fossil fuels (coal, oil, natural gas) 4. Example of the Greenhouse Effect The Suns energy passes through the cars 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. Whats the difference between global warming and climate change? 6. Difference GLOBAL WARMING is the increase of the Earths 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.

Simple Things To Do Turn off your computer or the TV when youre 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. Be Bulb SmartUse CFLs IncandescentWhats the difference?Compact Fluorescent500 lbs. of coal 1,430 lbs.

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.
