'''Metanoa''' [[hidrokarburo]] sinpleena da. Bere formula CH<sub>4</sub> da, beraz [[karbono]] molekula bat eta [[hidrogeno]] lau molekulaz osatua dago.

Gaur egun aldaketa klimatikoaren eragile nagusia CO2–a dela uste den arren badaude beste gas batzuk bera baino potentzial handiagoa dutenak eta [[berotegi efektu]]an parte hartzen dutenak. Adibidez metanoak CO2–ak baino hogei bat aldiz bero gehiago hartzen du, baina esan beharra dago metanoaren igorpenak azken urte hauetan mantendu egin direla eta CO2–arenak ostera era nabarmenean hasi direla.
