Cymraeg: Effaith yr haul ar newid hinsawdd? Dim llawer!
Dyn sy'n gyfrifol am newid hinsawdd a chynhesu byd eang. Mae'r fideo bychan yma'n gofyn y cwestiwn pam. Fideo: Terra X; llais a chyfarwyddo: Robin Llwyd ab Owain. Testun: Profwyd yn bendant fod newid hinsawdd yn cael ei achosi gan ddyn. Ceir hefyd newid naturiol yn nhymheredd y blaned, a achosir gan yr haul. Mae'r Ddaear yn cylchdroi mewn symudiad eliptig o gwmpas yr haul; ac mae'r gwahaniaeth yn y pellter yma'n newid yr hinsawdd. cafwyd cyfnodau cynnes a chyfnodau oer bob yn hyn a hyn yn ystod y miliwn neu ddwy o flynyddoedd diwethaf. Mae tymheredd yr haul hefyd yn newid, dros gyfnod hir o amser. Ar ben hyn, mae gogwydd y Ddaear ar ei echel yn achosi i'r haul dywynnu mewn ffyrdd gwahanol ar ein planed fechan. Ond a oes gan y nodweddion naturiol hyn unrhyw beth o gwbwl i'w wneud a'n newid hinsawdd cyfoes ni? Mae ymbelydredd yr haul sy'n treiddio i'n daear ni wedi gwanhau dros y blynyddoedd diwethaf. Os mai'r haul sy'n gyfrifol am y newid hinsawdd yna byddai wedi oeri, nid cynesu! Nid yr haul ydy'r broblem, felly. Cytnhesu mae'r Ddaer, nid oeri. Mewn geiriau eraill, nid yr haul yw achos y newid hinsawdd presennol. |
