Professor Tannecia Stephenson is a Physics Professor and Senior Lecturer who currently holds the post of Deputy Dean in the Faculty of Science and Technology, Mona. She was the first female Head of the Physics Department. Professor Stephenson's B.Sc. was in physics and she was awarded her Ph.D. in physics from The UWI in 2005 for her thesis which examined the Caribbean Dry Season: its modes, circulation features and statistical models. Professor Stephenson is the Co-Director of the UWI Climate Studies Group Mona (CSGM) which has produced a series of key studies and reports being used to guide climate change mitigation and resilience in Jamaica and the Caribbean. Professor Stephenson served on the Intergovernmental Panel on Climate Change (IPCC) which produced several assessment reports which are foundational in understanding the scientific basis of climate change, its impacts, risks, and strategies for adaptation and mitigation and have shaped global climate policies and actions. Her most recent international role was as a member of the team of current and former scientists from the IPCC who met with judges from the International Court of Justice (ICJ) in The Hague to share critical insights from the IPCC's assessment reports to assist the ICJ in its preparation of an advisory opinion on state obligations regarding climate change. This advisory opinion was requested by the United Nations General Assembly and underscores the importance of clarifying the legal responsibilities of states in addressing the global climate crisis.
