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.

Effects of Global Warming
Polar ice caps melting
• Raise sea levels.
• Raise temperatures
• Affects Wildlife
As the temperature of oceans rise, so will the probability of more frequent and stronger hurricanes.
Warmer waters and more hurricanes
Spread of disease
As northern countries warm, disease carrying insects migrate north, bringing plague and disease with them.
LETS SEE SOME MORE EFFECTS
Why is global warming
happening?
Rapid CO2 IncreasesRapid CO2 Increases
Burning of Fossil Fuels in plants, factories, cars and houses
Methane from rice paddies both ends of animals, garbage in landfills and mining operations
Nitrous oxide from fertilizers and other chemicals
Possible Solutions to Global Warming
• Conservation– Reduce energy needs– Recycling
• Alternate energy sources– Nuclear– Wind– Geothermal– Hydroelectric– Solar– Fusion
• Keep rooms cool by closing the blinds, shades, or curtains.
