이번 학기 콜로퀴움은 학교의 권고를 따라, 사회적 거리두기 단계와 연계하여 온라인 혹은 오프라인(온라인 방송 병행)으로 운영될 예정입니다.
여섯번째 강연에는 부산대학교 IBS Center for Climate Physics, Axel Timmermann 교수님을 모시고 콜로퀴움을 개최하오니, 학과 구성원 여러분의 많은 참여를 부탁 드립니다.
코로나19 확산방지를 위해 다과는 제공하지 않습니다.
1. Title: Physics of Global Warming
2. Speaker: Prof. Axel Timmermann (부산대학교, IBS Center for Climate Physics)
3. Date & Time: Oct. 28. (Wed.) 2020. 4:30 PM
4. Place: Natural Science 1, Room No. 31214
5. Abstract: Global Warming is real. Over the past 100 years our planet has warmed by ~1 degree Celsius. The majority of the warming since the 1950s can be attributed to human activities, namely fossil fuel burning. Climate model simulations show that this warming will continue, unless severe reductions of greenhouse gas emissions are imposed worldwide. Climate scientists are confident about these conclusions, because their understanding of the climate system is rooted in the equations of physics.
This presentation will give a brief overview into the physics of our climate system and its response to past, present and future radiative perturbations. We will discuss the key differences between weather and climate, the concepts of initial value and boundary value problems, the notion of internal versus forced climate variability and the fundamental thermodynamic, hydrodynamic, chemical and radiation equations that describe the coupled atmosphere-ocean-ice-land-carbon cycle system. Towards the end of my presentation I will show some new computer model simulations that capture the effects of increased greenhouse gas emissions on our planet with an unprecedented spatial resolution.
