UPSC Geoscientist – 2021

Naturally occurring greenhouse gases (like water vapour, carbon dioxide, methane, etc.) trap heat in the Earth’s atmosphere through the greenhouse effect. This process warms the planet’s surface significantly.

Without the natural greenhouse effect, Earth’s average surface temperature would be about -18°C. With it, the average temperature is around +15°C.

The difference between these two temperatures (-18°C and +15°C) is approximately 33°C. This is the warming effect provided by naturally occurring greenhouse gases. Human activities emitting additional greenhouse gases enhance this natural effect, leading to global warming.
