Question

Increase in the amount of $C{O}_2$ in air results in:

• A. Grey House Effect
• B. Global freezing
• C. Green House Effect
• D. Rain

Answer 1

The correct option is C

Green House Effect

Increase in amount of $C{O}_2$ in air results in global warming and enhanced greenhouse effect.

Earth is heated by a part of reflected radiation (from the surface) and this heat is trapped by the atmosphere. Certain gases like $C{O}_2$ increase the amount of heat energy trapped leading to what is termed as enhanced greenhouse effect. This phenomenon has led to global warming which is climate change driven by a steady increase in average temperature of earth's atmosphere in the last many decades.
