Question

1. what is one consequence of increased carbon dioxide in the atmosphere?

a. decreased solar radiation
b. enhanced ice core stability
c. reduced sea levels
d. increased global warming potential

Explanation:

To solve this, we analyze each option:

• Option a: Solar radiation is from the sun; \( \text{CO}_2 \) doesn’t decrease it. Eliminate.
• Option b: Increased \( \text{CO}_2 \) causes warming, melting ice, so ice core stability decreases. Eliminate.
• Option c: Warming melts ice, increasing sea levels, not reducing. Eliminate.
• Option d: \( \text{CO}_2 \) is a greenhouse gas; more \( \text{CO}_2 \) enhances global warming potential (traps more heat). This is correct.

Answer:

d. Increased global warming potential
