Question

Given below are two statements:
Statement I: If the ozone concentration decreases in the atmosphere, more UV radiation will reach the earth's surface.
Statement II: The adverse effect of \(1^{\circ}C\) in temperature can be compensated by increasing \(\mathrm{CO_2}\) concentration up to 600 ppm.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is correct but Statement II is false
• D. Statement I is incorrect but Statement II is true

Hint:

Climate change effects:
- Ozone depletion increases UV radiation.
- CO2 fertilization can partially offset temperature increases.
- Both are important environmental issues.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
This question tests knowledge of the effects of ozone depletion and climate change.

Step 2: Detailed Explanation:
Ozone depletion reduces the absorption of UV radiation, allowing more UV to reach the Earth's surface.
This statement is true.
The adverse effects of a \(1^{\circ}C\) increase in temperature can be compensated by increasing CO2 concentration to 600 ppm.
This is based on the concept of CO2 fertilization and temperature compensation.
Thus, both statements are true.

Step 3: Final Answer:
Thus, both statements are true, which corresponds to option (A).
