Question

What is 'Green House Effect'?
1. Increase in global temperature
2. Decrease in global temperature
3. Increase in sea water temperature
4. Increase in temperature of rivers and lakes

Answer 1

Correct Answer - Option 1 : Increase in global temperature

The correct answer is Increase in global temperature .

• In simpler term, the greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. 
• When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
• Greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs).
• The absorbed energy warms the atmosphere and the surface of the Earth.
• The human activities such as burning fossil fuels (coal, oil and natural gas), agriculture and land clearing - are increasing the concentrations of greenhouse gases.
• This is the enhanced greenhouse effect, which is contributed to the global warming of the Earth .
• Methane is much more potent in terms of the greenhouse effect. Its global warming impact is 25 times greater than that of carbon dioxide over a 100-year period.
• The Paris Agreement speaks of the vision of fully realizing technology development and transfer for both improving resilience to climate change and reducing GHG (Green House Gas) emissions.
