3. How Global Warming Works Fossil fuels (coal, oil, natural gas) Carbon Dioxide (CO 2 )
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

Scientists agree that the burning of fossil fuels is causing global warming. Since these fuels are burned for energy, and everyone uses energy, everyone can help stop global warming just by using less energy or energy from renewable sources!
