Question
CFC’s play important role in greenhouse effect by_________.
- Thinning of ozone layer
- Absorption of solar radiation
- Blocking UV-B radiation
- None of these
Hint:
CFC cause ozone destruction
The correct answer is: Thinning of ozone layer
- CFCs provide a negative feedback to greenhouse warming through stratospheric ozone destruction, and as such, their net radiative forcing (global warming potential) is reduced
- So Thinning of ozone layer is correct
