Ancak bu etki seralar\u0131n i\u00e7ine hakim olan s\u0131cakl\u0131\u011f\u0131n tek sorumlusu de\u011fildir.

Bunlar, karbondioksit, su buhar\u0131, metan gaz\u0131, azot protoksit, ozon ve sentetik end\u00fcstri molek\u00fclleridir.

Ek sera etkisi de k\u00fcresel \u0131s\u0131nmay\u0131 tetikliyor.
