How Global Warming Works

Fossil fuels (coal, oil, natural gas)

Carbon Dioxide (CO2)

Greenhouse gases

Why Global Warming?

Effects of Global Warming Increased sea level Changes in water supply Rising temperature Damage to habitats

Warmer waters and more hurricanes

Increased probability and intensity of droughts and heat waves
