Climate Changes
- Greenhouse effect
- A fraction of the
heat goes directly
back into the space
- The rest is trapped in lower layers
- Caused by: Gases
and water vapor
- Increase heating
- More water
evaporation
- We produce
other greenhouse
gases
- Burning
Fossil fuels
- Causes
- 60% of warming
- Methane
- Causes
- 15% of warming
- Generated by
- Decomposing
Garbage
- Average of temperature
- Rise by 1 to 3.5 degrees
in the next hundred years
- Missing Carbon
- Oceans serve as a vast
"Sink" for Carbon Dioxide
- Human activity
release 7 billon metric
tones of carbon
- 3 Billon tons remain in
Air
