Frequently Asked Questions
How do greenhouse gases trap heat?
Greenhouse gases (CO2, methane, N2O, fluorinated gases) absorb and re-emit infrared radiation, warming the atmosphere. Global Warming Potential (GWP) compares gases to CO2 over 100 years: methane has a GWP of 28, N2O is 265. Total forcing is measured in watts per square meter and currently exceeds 3 W/m^2.
