The Greenhouse Gas Effect

• Natural process

• Radiant heat from the Sun is captured into lower atmosphere

• Helps maintain Earth’s surface

• Some gases are emitted naturally

• Some gases emitted through man kind

Global Warming WILL Impact Earth

1. Spread of disease

2. Warmer waters and more hurricanes

3. Increased probability of droughts and heat waves

4. Economic consequences

5. Polar ice caps melting

6. More floods

7. Fires and wildfires

8. Destructive storms

o Yes, temperatures are rising

o Animals are going extinct

o Glaciers are melting

o Adaptation will soon become unbearable

o Will the world end?

o Will this be the death of our race?
