er enghraifft , mae pob safle yn cynhyrchu methan ac yn cyfrannu at gynhesu byd-eang
for example , all sites produce methane and contribute to the greenhouse effect

mae plu lliw tywyll o arwyneb cefn pengwin yn amsugno gwres o'r haul, a'u helpu felly i gynhesu.
the dark coloured feathers of a penguin's back surface absorb heat from the sun, so helping them to warm up too.

nododd fod oddeutu 80 y cant o gynhesu byd-eang o ganlyniad i weithgarwch dynol ryw , yn arbennig gweithgarwch diwydiannol
it stated that around 80 per cent of global warming is the result of humankind's activities , particularly industrial activities

disgwylir i'r tueddiad hwn barhau , ac mae'n awgrymu y gall y boblogaeth gyfan o bysgod fynd yn llai hyfyw o ganlyniad i gynhesu byd-eang
this trend is expected to continue , and points to an entire population of fish becoming less viable in response to global warming

mae'n amlwg , os ydym am ddylanwadu ar gynhesu byd-eang , bod yn rhaid inni ddod o hyd i ffynonellau ynni glanach
it is clear that , if we are to have an impact on global warming , we must find cleaner sources of energy

ar ôl i hynny gael ei gydnabod -- [ torri ar draws . ] yr wyf yn siarad am gynhesu byd-ean ; mae'n digwydd
once that was recognised -- [ interruption . ] i am talking about global warmin ; it is taking place

bydd y cynllun newydd yn darparu amrywiaeth o fesurau a dargedir at sector y perchnogion tai a'r sector preifat ar rent er mwyn gwella cysur a iechyd y rhai na allant gynhesu eu tai yn ddigonol
the new scheme will provide a broad range of measures targeted at the home owner and private rented sectors with the aim of improving the comfort and health of those who cannot heat their homes adequately

gan hynny , rhaid i'r llywodraeth archwilio ei holl bolisïau a phenderfyniadau i asesu eu heffaith ar gynhesu byd-eang ac i anghefnogi'r defnydd o ynni sy'n seiliedig ar garbon
the government , therefore , needs to audit all of its policies and decisions to assess their impact on global warming and actively discourage energy use that is carbon based

cynhyrchydd trydan pwysig arall yw ynni niwclear ac , ar rai agweddau , mae'n opsiwn atyniadol gan nad yw'n cyfrannu at gynhesu byd-eang
nuclear power is another major electricity generator and is , in some ways , a tempting option as it does not contribute to global warming

a ydych yn ymwybodol o ymchwil ddiweddar sy'n dangos mai cylchredau planedol naturiol sy'n achosi'r rhan fwyaf o'r cynhesu byd-eang presennol ac nad yw'n ganlyniad i lygryddion o waith dyn ? fel yr awgrymodd phil , mae'r rhan fwyaf o gynhesu byd-eang yn deillio o garbon deuocsid , ac nid methan
are you aware of recent research that shows that most of the current global warming is due to natural planetary cycles , and that it is not the result of man-made pollutants ? as phil suggested , the majority of global warming results from carbon dioxide , not methane
