Lesson 2: Greenhouse effect

Greenhouse effect

AP.ENVSCI: STB‑4 (EU), STB‑4.C (LO), STB‑4.C.1 (EK), STB‑4.C.2 (EK), STB‑4.C.3 (EK), STB‑4.D (LO), STB‑4.D.1 (EK), STB‑4.E (LO), STB‑4.E.1 (EK)

Several factors influence how much a given greenhouse gas contributes to global warming, as shown in the table below.

	Global warming potential (100 years)	Residence time (years)	Concentration (ppmv)
Carbon dioxide $\ce{(CO2)}$	1	5, minus, 200	449
Methane $\ce{(CH4)}$	28	12, point, 4	1, point, 7, minus, 1, point, 8
Nitrous oxide $\ce{(N2O)}$	265	121	1, point, 869
Trichlorofluoromethane $\ce{(CFCl3)}$	4, comma, 750	45	0, point, 00022
