Glaciers will advance. The sea level will rise. Earthquake activity will increase. The overall temperature will decrease.
I gave my students this multiple choice question: The news often talks about how global warming could change environmental conditions on Earth. Which best explains why global warming is such a concern?

Only one answer is correct among these 4 choices:
- Glaciers will advance.
- The sea level will rise.
- Earthquake activity will increase.
- The overall temperature will decrease.

Could you tell me which one is correct?

The sea level will rise.
