Uchafbwyntiau Gyrfa
Ymchwil
Prif Wobrau
Dynameg Amgylcheddol
Mae ein hymchwil yn canolbwyntio ar amrywioldeb amgylcheddol yn ystod y cyfnod Cwaternaidd ac effeithiau newidiadau yn yr hinsawdd yn y dyfodol. Ffocws ein hymchwil yw’r rhanbarthau hynny sy’n arbennig o sensitif i newidiadau yn yr hinsawdd (gan gynnwys hinsoddau trofannol ac oer a’r rheiny sy’n dioddef o danau gwyllt). Mae hefyd yn ystyried y rhyngweithio rhwng newidiadau yn yr hinsawdd, ymyrraeth ddynol a digwyddiadau trychinebus.

GEG133 Natural Hazards and Society
This module investigates hazardous aspects of Earth¿s natural environment and how society relates to them. Introductory principles include the definition of natural hazard, disaster, risk and loss, and approaches to reducing risk and managing disasters. Major types of natural hazard are studied in order to understand how they operate, where, and how frequently they are likely to occur. Hazardous consequences are explored, as well as how society can respond to hazardous events. Key aspects include discussion of primary and secondary hazards, prediction, forecasting and monitoring of hazards, and understanding how their harmful effects can be minimized. Natural hazards considered during this module include volcanic eruptions, earthquakes, tsunamis, wildfires, landslides, extreme weather events, flooding, avalanches and Mega Hazards. Lecture material considers general principles as well as case studies.

GEG133C Peryglon Naturiol a Chymdeithas
Mae'r modiwl hwn yn archwilio agweddau peryglus ar amgylchedd naturiol y Ddaear a pherthynas cymdeithas â nhw. Bydd egwyddorion cychwynnol yn cynnwys diffiniad o berygl naturiol, trychineb, risg a cholled ac ymagweddau at leihau risg a rheoli trychinebau. Mae¿r prif fathau o berygl naturiol yn cael eu hastudio er mwyn deall sut maent yn gweithredu, ble, a pha mor aml maent yn debygol o ddigwydd. Caiff canlyniadau peryglus eu hystyried, yn ogystal â sut gall cymdeithas ymateb i ddigwyddiadau peryglus. Mae agweddau allweddol yn cynnwys trafod peryglon cynradd ac eilradd, rhagweld a monitro peryglon, a deall sut y gellir lleihau eu heffeithiau niweidiol. Bydd y peryglon naturiol a fydd yn cael eu hystyried yn y modiwl hwn yn cynnwys ffrwydradau llosgfynyddoedd, daeargrynfeydd, tswnamïau, tanau gwyllt, tirlithriadau, digwyddiadau tywydd eithafol, llifogydd, cwympfeydd eira a Pheryglon Mawr. Mae deunydd darlithoedd yn ystyried egwyddorion cyffredinol yn ogystal ag astudiaethau achos.

GEG135 Sustainability and the Climate Emergency
This module explores the urgent challenges posed by climate change and the broader sustainability crisis through a dynamic, interdisciplinary lens. In this interactive module, you¿ll examine the science, politics, and lived realities of the climate crisis. You¿ll learn how societies have shaped the planet, how climate change affects people and ecosystems, and how we can imagine and build more sustainable futures. Through lectures, debates, case studies, and a hands-on climate negotiation simulation, you¿ll develop critical thinking skills and explore real-world challenges. You¿ll also gain experience with systems thinking and futures mapping¿skills that are increasingly valued in sustainability-related careers. Whether you're passionate about climate action, curious about global environmental politics, or looking to understand how societies can transition toward sustainability, GEG135 offers a rich and engaging foundation. Cymraeg Mae'r modiwl yma yn archwilio¿r heriau brys sy¿n deillio o newid hinsawdd a¿r argyfwng cynaliadwyedd ehangach o safbwynt ryngddisgyblaethol a deinamig. Yn yr modiwl rhyngweithiol yma, byddwch yn archwilio gwyddoniaeth, gwleidyddiaeth a realiti byw¿r argyfwng hinsawdd. Byddwch yn dysgu sut mae cymdeithasau wedi siapio¿r blaned, sut mae newid hinsawdd yn effeithio ar bobl ac ecosystemau, a sut y gallwn ddychmygu a chreu dyfodol mwy cynaliadwy. Drwy ddarlithoedd, dadleuon, astudiaethau achos ac efelychiad trafodaeth hinsawdd ymarferol, byddwch yn datblygu sgiliau meddwl beirniadol ac yn archwilio heriau¿r byd go iawn. Byddwch hefyd yn meithrin profiad o feddwl systemig a mapio¿r dyfodol¿sgiliau sy¿n gynyddol werthfawr mewn gyrfaoedd sy¿n ymwneud â chynaliadwyedd. P¿un a ydych yn angerddol am weithredu ar newid hinsawdd, yn chwilfrydig am wleidyddiaeth amgylcheddol fyd-eang, neu¿n awyddus i ddeall sut y gall cymdeithasau bontio tuag at gynaliadwyedd, mae GEG135 yn cynnig sylfaen gyfoethog a chyffrous.
