What is the natural greenhouse gas effect?
The heating of the atmosphere due to the presence of greenhouse gasses.
What is the enhanced greenhouse gas effect?
The increased warming of the atmosphere due to an increased amount of greenhouse gasses released by human activity.

(water)
CO2
Methane
Nitrous oxide
What is Earth’s average surface temperature?
15*C
What are some global impacts of the enhanced greenhouse effect?
- Increased sea level
- Global average temperature increase
- ocean acidification
- Impact on human health (prolonged heat waves)
Regional impacts of enhanced greenhouse effect?
