Answer 1

Increase in carbon dioxide in atmosphere is harmful because it traps heat.

Explanation:

Carbon dioxide is a major greenhouse gas that traps heat in the Earth’s atmosphere by absorbing infrared radiation emitted from the Earth’s surface and re-radiating it back, causing the greenhouse effect. This leads to global warming, which can result in melting polar ice caps, rising sea levels, and changes in climate patterns worldwide. Hence, elevated CO₂ levels warm the lower atmosphere and disrupt natural climate balance.
