Nicolas is a local fresh graduate in Earth System Science at the Chinese University of Hong Kong. He is intrigued by the complex air-sea-ice interaction in the planet Earth. He has been an exchange student at the University Centre in Svalbard far up in the Arctic and involved in organising global climate strikes there. He is enthusiastic about raising public awareness towards climate change and taking climate actions. He is joining HKCES since he thinks this is an invaluable event for youths to voice out our determination towards achieving the sustainable development goals.
