What is Greenhouse Effect?

The greenhouse effect is the process by which greenhouse gases in Earth's atmosphere absorb and re-emit infrared radiation, warming the planet's surface. Without any greenhouse effect, Earth's average temperature would be about −18°C instead of the current +15°C. The enhanced greenhouse effect, caused by increased concentrations of CO₂, CH₄, N₂O, and other gases from human activities, is driving global climate change.

Properties & Characteristics

Greenhouse gases: CO₂, CH₄, N₂O, H₂O vapor, O₃, fluorinated gases. Global Warming Potential (GWP) measured relative to CO₂ (=1). CH₄ GWP = 86 (20-yr) or 34 (100-yr). N₂O GWP = 268 (20-yr) or 298 (100-yr). Natural greenhouse effect: +33°C warming. Enhanced effect: atmospheric CO₂ now >420 ppm (pre-industrial: 280 ppm).

Uses & Applications

Understanding climate change and global warming. Environmental policy and carbon trading. Carbon capture and storage technology. Renewable energy transition rationale. Agriculture adaptation planning. International climate agreements (Paris Agreement, Kyoto Protocol).

Safety Information

The greenhouse effect itself is a natural and necessary phenomenon. The enhanced greenhouse effect from fossil fuel combustion causes: sea level rise, extreme weather events, species extinction, food security risks, and public health impacts. International scientific consensus (IPCC) classifies it as an existential risk.
