Chemistry - Environmental Chemistry Question with Solution | TestHub

Question Explanation :

Consequence of rising ${\mathrm{CO}}_2$ levels.

Concept: Greenhouse effect and thermal radiation.

Solution : An increase in CO₂ concentration leads to Global Warming.

CO₂ acts as a "greenhouse gas" by allowing short-wavelength solar radiation to pass through the atmosphere while absorbing and re-emitting long-wavelength infrared radiation (heat) reflected from the Earth's surface.

This trapped heat prevents the planet's surface from cooling, causing a gradual increase in the average global temperature.

While CO₂ is essential for photosynthesis (natural vegetation), excessive levels disrupt the climate balance, leading to melting ice caps and rising sea levels rather than direct genetic disorders.

Final Answer: Option (B)
