GLOBAL WARMING is the increase of the

Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere.

How Global Warming Works

Fossil fuels (coal, oil, natural gas)

Carbon Dioxide (CO2)

Greenhouse gases

CAUSES OF GLOBAL

WARMING

Pollution from coal, natural gas, and oil

CO2 from

airplanes & vehicles

POPULATION POPULATION INCREASE INCREASE

DEFORESTATIODEFORESTATIONN

Increased CO2

results in

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

Melting of glaciers

Polar Bear Extinction

Warmer waters and more hurricanes

Increased probability and intensity of droughts and heat waves

Increased Temperature

Major CONSEQUENCE of
