 Felly, we're here at the COP 22 in Marrakesh to agree the rules by which the Paris Agreement will operate. At the moment, within the Paris Agreement it's possible for a country to update their undertaking or their pledges for action on climate change at any point and they're all making their pledges in very different terms. Rhywbeth ymlaes wnaeth yma yw'r mewn gwahoddio'r cyffredinol a'u cyfyrdd i fwyaf i'w gwahoddio'r cyfredinol i'w gwahoddio'r cyffredinol.
