Cynhaliwyd cynhadledd i'r wasg yn Ewrop yr wythnos hon, lle rhoddodd yr Athro Guus Berkhout o'r Sefydliad Deallusrwydd Hinsawdd wybodaeth am y 700 o lofnodion a gasglodd oddi wrth wyddonwyr a gweithwyr proffesiynol blaenllaw, gan gynnwys enillydd gwobr Nobel. Maent yn datgan nad oes argyfwng hinsawdd, a hefyd bod pedwar o fynegeion gwyddonol newydd wedi cofnodi bod tymheredd y ddaear wedi gostwng 0.47 y cant yn ystod y degawd diwethaf, er gwaethaf y cynnydd o 2 y cant mewn carbon deuocsid, ac mae datgeliadau newydd yn dangos bod gan y byd y lefelau uchaf erioed o orchudd eira, sy'n cynnwys y ffaith mai'r eira sy'n gorchuddio hemisffer y Gogledd yw'r pumed uchaf yn y 52 mlynedd diwethaf. A wnaiff y Llywodraeth ddatganiad ynghylch a fydd yn parhau i dderbyn yr honiad hollol wallus hwn bod yna argyfwng newid hinsawdd a chynhesu byd-eang, oherwydd mae eich ymgais i fynd ar drywydd polisïau sy'n derbyn y ffaith hon yw gwthio niferoedd cynyddol o bobl yng Nghymru i dlodi tanwydd?

Given that a press conference was held in Europe this week, at which Professor Guus Berkhout of the Climate Intelligence Foundation gave information on the 700 signatures he has collected from prominent scientists and professionals, including a Nobel Prize winner, where they declare there is no climate emergency, and also that four new scientific indices have recorded that the earth's temperature has actually fallen by 0.47 per cent over the last decade, despite the 2 per cent rise in carbon dioxide, and new revelations that show the world is actually experiencing record levels of snow cover, which includes the fact that snow covering the northern hemisphere is the fifth highest for the last 52 years, would the Government make a statement on whether it will continue to accept this totally erroneous assertion that there is a climate change and global warming crisis, because your pursuit of policies that are accepting of this fact is pushing increasing numbers of people in Wales into fuel poverty?

Mae anghydfodau, yn gyffredinol, wedi eu canolbwyntio ar arian a grym. Prif Weinidog, ystyrir yn gyffredinol eich bod chi wedi cael hanes cymharol lwyddiannus o ran cytuno ar y fframwaith cyllidol gyda Llywodraeth y DU i ddatrys y cyllid sy'n dod i Gymru. Fe wnaeth eich rhagflaenydd, yn fy marn i, waith da wrth negodi â Llywodraeth y DU ynglŷn â phwerau'r Cynulliad hwn a'r setliad datganoli yng nghyd-destun Brexit. Onid yw hynny'n dangos mai negodi fydd y dull hanfodol ar gyfer datrys anghydfod yn gyffredinol?

Disputes, generally, centre on money and power. First Minister, you're generally thought to have had a fairly successful record at negotiating the fiscal framework with the UK Government to resolve the funding coming to Wales. Your predecessor, I would say, did a good job negotiating with the UK Government about the powers of this Assembly and the devolution settlement in the Brexit context. Doesn't that show that the essential mechanism for resolving disputes will generally be that of negotiation?

Fe wnes i wrando ar yr hyn y gwnaethoch chi ei ddweud; rydych chi'n dweud ein bod ni wedi cael cyfle i gynllunio cyfundrefn benodol ar gyfer rheoli cymhorthdal ledled y DU yn yr achos hwn. Ydych chi, felly, yn gresynu bod Llywodraeth y DU wedi anwybyddu'r holl sylwadau a wnaed gan Lywodraeth Cymru a'r Senedd hon?

I listened to what you said; you say that we've had an opportunity to design a specific UK-wide subsidy control regime in this instance. Do you, therefore, regret that the UK Government has ignored all the representations made by both the Welsh Government and this Senedd?
