What is mainly responsible for the increase in the greenhouse effect?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. Increasing CO2 concentration.

  • The increase in the greenhouse effect is primarily attributed to the rise in carbon dioxide concentrations in the atmosphere.
  • This rise is largely due to human activities such as the burning of fossil fuels—coal, oil, and natural gas—for energy and transportation. Additionally, deforestation contributes by reducing the number of trees that can absorb carbon dioxide.
  • Industrial processes also release significant amounts of carbon dioxide. The elevated carbon dioxide levels trap more heat in the atmosphere, enhancing the greenhouse effect and contributing to global warming and climate change.
