Which of the following is not likely to happen as a result of the rising levels of `CO_(2)` in our atmosphere ?

Options

A. increased incidence of skin cancers
B. rise in sea levels
C. change in climatic patterns
D. shift in locations of deserts and forests

Answer

To determine which of the following is not likely to happen as a result of rising levels of CO2 in our atmosphere, we can analyze each option based on the effects of increased CO2 levels.

### Step-by-Step Solution:

1. **Understanding CO2 as a Greenhouse Gas**:
- CO2 is a greenhouse gas that contributes to global warming. As CO2 levels rise, they trap more heat in the atmosphere, leading to an increase in Earth's average temperature.

2. **Analyzing the Effects of Global Warming**:
- **Increased Incidence of Skin Cancers**: This is related to the destruction of the ozone layer, which is affected by greenhouse gases. However, CO2 itself does not directly cause skin cancer; it is UV radiation that does. Thus, while rising CO2 levels can contribute to ozone depletion, the direct link to skin cancer is not strong.
- **Rise in Sea Levels**: As global temperatures increase, polar ice melts, leading to rising sea levels. This is a likely consequence of increased CO2 levels.
- **Change in Climatic Patterns**: Global warming affects weather patterns, leading to changes in seasons and precipitation. This is a direct consequence of rising CO2 levels.
- **Shift in the Location of Deserts and Forests**: While climate change can influence ecosystems, the direct shift in desert and forest locations is more closely related to deforestation and land use changes rather than CO2 levels alone.

3. **Identifying the Correct Answer**:
- The option that is least likely to happen as a direct result of rising CO2 levels is the **shift in the location of deserts and forests**. This phenomenon is more closely associated with human activities like deforestation rather than the increase in CO2 levels.

### Conclusion:
The answer to the question is that the **shift in the location of deserts and forests** is not likely to happen as a direct result of rising levels of CO2 in our atmosphere.
