Fossil fuels are at the verge of getting exhausted. It is because of their non-replenishment, increasing demand, increasing population and more energy dependent technologies. Therefore, one has to look up to the sources which can be regenerated and cause the minimum possible environmental damage.
Which of the following are the major effects of global warming caused due to burning of fossil fuels?
A. Changes in weather.
B. Melting of all the glaciers into water
C. Deforestation

Options

A. A and C
B. A, B and C
C. A and B only
D. B and C only

Answer

To answer the question regarding the major effects of global warming caused by the burning of fossil fuels, let's analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Global Warming**:
- Global warming refers to the increase in Earth's average surface temperature due to rising levels of greenhouse gases, primarily carbon dioxide (CO2), which is released from burning fossil fuels.

2. **Analyzing Option A: Changes in Weather**:
- The burning of fossil fuels contributes to global warming, which alters weather patterns. This can lead to extreme weather events, changes in precipitation, and shifts in climate zones.
- **Conclusion**: This option is a major effect of global warming.

3. **Analyzing Option B: Melting of All Glaciers into Water**:
- As global temperatures rise, glaciers and polar ice caps are melting, contributing to rising sea levels. While it is not accurate to say "all" glaciers will melt, significant melting is indeed occurring and is a direct consequence of global warming.
- **Conclusion**: This option is also a major effect of global warming.

4. **Analyzing Option C: Deforestation**:
- Deforestation itself is a contributing factor to global warming rather than an effect. Trees absorb CO2, and when they are cut down, this carbon is released back into the atmosphere, exacerbating global warming.
- **Conclusion**: This option is not a major effect of global warming.

### Final Answer:
- The major effects of global warming caused due to burning of fossil fuels are:
- A. Changes in weather
- B. Melting of glaciers into water
