Mewn perthynas â’r eitem ar COP26, yng nghyd-destun hinsawdd sy'n newid, galwais ar Lywodraeth y DU, drwy ei Hadolygiad Cynhwysfawr o Wariant a gyhoeddir yn fuan, i ddarparu cyllid ychwanegol i fynd i’r afael â gwaddol y tomenni glo o’r cyfnod cyn datganoli. Gofynnais iddynt sicrhau bod y tomenni hynny yn ddiogel wrth inni wynebu tywydd gynyddol eithafol o ganlyniad i newid hinsawdd. Mae hwn bellach yn fater tyngedfennol. Mae gan y tomenni glo hanes trasig ac mae’r bygythiad – sy’n cynyddu yn sgil newid hinsawdd – yn un gwirioneddol i bobl a chymunedau ar draws Cymru. Diolch i ymdrechion y cymunedau hyn, crëwyd cyfoeth a daethpwyd â budd economaidd anhygoel i'r DU dros y canrifoedd a aeth heibio – mae hawl ganddynt ddisgwyl cyllid hirdymor gan y DU i fynd i’r afael â'r safleoedd hyn.
In relation to the item on COP26, in the context of a changing climate, I called on the UK Government through its forthcoming Comprehensive Spending Review to provide additional funding to deal with the pre-devolution legacy of coal tips and to ensure they are safe as we face increasing extreme weather as a result of climate change. It is now a critical issue with a tragic history which poses real risks – which climate change is exacerbating – for people and communities across Wales. Those communities whose efforts created huge wealth and economic benefit to the UK in centuries past have a right to look to the UK for long-term funding to deal with these sites.
