Weaker IR radiation, however, has difficulty passing through the glass walls and is trapped inside, thus warming the greenhouse. This effect lets tropical plants thrive inside a greenhouse, even during a cold winter.
Water vapor is the biggest contributor to the greenhouse effect; However CO2 & other greenhouse gases are increasing the amount of water vapors in the air by boosting the rate of evaporation

Green House Effect Contributors
Water vapor is the biggest contributor to the greenhouse effect; However CO2 & other greenhouse gases are increasing the amount of water vapors in the air by boosting the rate of evaporation- Major Contributors: CO2 (Fossil fuels) > CO2 (Deforestation) > CH4 > N2O
- Major Sources: Electricity >Transportation > Industry > Commercial & Residential
- Rate of evaporation rises with temperature, the amount of water vapour at any time is strongly related to the amount of other greenhouse gases in the air.
- Wetlands – largest source of CH4 due to bacteria that decomposes organic material in absence of air
- Globally, Agriculture sector is primary source of CH4 emission via animal manure biogas
- Methane is also the primary constituent of Natural gas
- Black carbon commonly known as soot is a form of particulate air pollutant, produced from incomplete combustion (Consist of pure carbon & strongest absorber of sunlight)
Global Warming Potential
- a relative measure of how much heat a greenhouse gas traps in the atmosphere
- compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide
- GWP of Primary CHGs – SF6 > PFCs > HFCs > N2O > CH4 > CO2
