(iii) Increased frequency of extreme events like floods , drought , etc.
(iv) Altered range of disease , vectors, pathogens , etc.

Options

A. (i) only
B. (ii) and (iv)
C. (i) and (ii)
D. (i) , (ii), (iii) and (iv)

Answer

To determine the effects of global warming based on the provided statements, let's analyze each one step by step.

### Step-by-Step Solution:

1. **Increased capacity of air to accommodate moisture**:
- Global warming leads to an increase in temperature. Warmer air can hold more moisture, which means that as temperatures rise, the capacity of the atmosphere to retain water vapor also increases. This is a well-documented phenomenon in climate science.
- **Conclusion**: This statement is **correct**.

2. **Altered wind movement pattern**:
- Changes in temperature gradients due to global warming can affect wind patterns. As the Earth warms, the distribution of heat changes, which can lead to alterations in wind currents and patterns. This can affect weather systems globally.
- **Conclusion**: This statement is **correct**.

3. **Increased frequency of extreme events like floods, droughts, etc.**:
- Global warming contributes to the melting of glaciers and ice caps, leading to rising sea levels and increased flooding. Additionally, changes in precipitation patterns can lead to more frequent droughts in certain areas. The overall increase in temperature can intensify weather events, making them more extreme.
- **Conclusion**: This statement is **correct**.

4. **Altered range of disease vectors, pathogens, etc.**:
- Climate change can affect the habitats and ranges of various disease vectors (like mosquitoes) and pathogens. Warmer temperatures can expand the range of these organisms, potentially leading to the spread of diseases into new areas.
- **Conclusion**: This statement is **correct**.

### Final Conclusion:
All four statements regarding the effects of global warming are correct. Therefore, the answer to the question is that all the listed effects are indeed consequences of global warming.
