Då behövs ytterligare kontroller och åtgärder göras. Ökningstakten av koldioxidhalten (CO2) i atmosfären de senaste 70 åren är nära 100 gånger så stor som efter slutet av den senaste istiden. Utifrån observationer har så kraftiga förändringar av koldioxidhalten i atmosfären aldrig tidigare skett. CO2.Earth connects the general public with the latest data and information for stabilizing earth's atmosphere, climate and living environments.
