Ocean levels would increase. Human population would increase. Vegetation in water would decrease. Global precipitation would decrease.
I gave my students this multiple choice question: Many scientists theorize that global warming will melt the polar ice caps. What would most likely happen if the polar ice caps melted?

Only one answer is correct among these 4 choices:
- Ocean levels would increase.
- Human population would increase.
- Vegetation in water would decrease.
- Global precipitation would decrease.

Could you tell me which one is correct?

Ocean levels would increase.
