The global warming has resulted in

Options

A. the increase in yield of crops
B. the decrease in sea levels
C. the decrease in human deaths
D. the increase in sea levels

Answer

**Step-by-Step Solution:**

1. **Understanding Global Warming:**
- Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases.

2. **Impact of Greenhouse Gases:**
- Greenhouse gases trap heat in the atmosphere, leading to an increase in temperature. This warming affects various natural processes.

3. **Melting of Glaciers:**
- As temperatures rise, glaciers and ice caps, particularly in polar regions, begin to melt. This melting contributes to the overall volume of water in the oceans.

4. **Thermal Expansion of Water:**
- In addition to the melting ice, warmer temperatures cause ocean water to expand. This phenomenon is known as thermal expansion, which also contributes to rising sea levels.

5. **Increase in Sea Levels:**
- The combination of melting glaciers and thermal expansion of seawater results in an increase in sea levels. This poses a threat to coastal regions and ecosystems.

6. **Conclusion:**
- Therefore, the result of global warming is an increase in sea levels, which is a significant environmental concern.

**Final Answer:**
The global warming has resulted in an increase in sea levels.
