Horizon Talk: Limiting warming to 1.5°C – a matter of societal will, not science

Wednesday 15th April 5.00pm

Climate impacts are hitting home, with weather and climate extremes breaking records every consecutive year. If we continue to pollute the atmosphere with greenhouse gases, these impacts are projected to only increase with detrimental effects for people and nature. The urgency to act is clear. In this talk we take a look at the UN Intergovernmental Panel on Climate Change’s (IPCC) Special Report on Global Warming of 1.5°C to understand what science tells us about where we are, what climate impacts we expect, and what we can do to respond to the global climate change challenge.

Dr Joeri Rogelj is a Climate Change Lecturer at the Grantham Institute at Imperial College London. He researches the linkages between climate physics and international climate policy, and has published widely on the effectiveness of international climate agreements including the Copenhagen Accord and the Paris Agreement, carbon budgets, implications of delaying climate mitigation action, global zero emission targets, the interaction between climate and sustainable development, and pathways in line with limiting global warming to 1.5°C and 2°C.
Over the past decade, Joeri Rogelj has contributed to and led several major scientific climate change assessments. He is a long-serving lead author on the Emissions Gap Reports; these are annual policy synthesis reports by the United Nations Environment Programme (UNEP). He contributed to the physical science and climate change mitigation assessment of Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), was one of the Coordinating Lead Authors for the IPCC Special Report on 1.5°C of Global Warming, and is a Lead Author on carbon budgets for the IPCC’s Sixth Assessment. He continues to follow the UN climate negotiations as a scientific advisor and is currently the youngest member serving on the UN Secretary-General’s Climate Science Advisory Group.
