Increase in the carbon dioxide levels in the atmosphere has gradually led toa phenomenon known as _______

Options

A. Eutrophication
B. Global warming
C. Green house effect
D. Oil spill

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the phenomenon caused by the increase in carbon dioxide levels in the atmosphere.

2. **Identifying the Cause**: Carbon dioxide (CO2) is a greenhouse gas. When its levels rise in the atmosphere, it leads to an enhanced greenhouse effect.

3. **Explaining the Greenhouse Effect**: The greenhouse effect occurs when certain gases in the Earth's atmosphere trap heat from the Sun. This process is essential for keeping our planet warm enough to support life.

4. **Consequences of Increased CO2**: As CO2 levels increase, more heat is trapped, leading to a rise in the Earth's average temperature.

5. **Defining the Phenomenon**: The increase in the Earth's temperature due to the accumulation of greenhouse gases, particularly CO2, is referred to as "Global Warming."

6. **Final Answer**: Therefore, the phenomenon caused by the increase in carbon dioxide levels in the atmosphere is known as **Global Warming**.
