The greenhouse effect
Changes in atmospheric composition
13
How does a temperature inversion affect air pollution?
It disperses pollutants, improving air quality
It traps pollutants close to the ground, increasing air pollution levels
It has no effect on air pollution
It only occurs over the ocean
14

16
Why is confusing weather with climate problematic?
All of the above
It affects short-term economic policies
