Joint GSI & Tipping Points seminar: Jonathan Rosser - Physical Uncertainties and Economic Impacts of Climate Tipping Points


Event details

Climate tipping points such as the collapse of the Atlantic Meridional Overturning Circulation (AMOC) and the polar ice sheets are currently assessed to have a significant chance of tipping this century. This could potentially lead to large impacts on the global economy and human society. However, there are huge uncertainties in both the physical behaviour and economic impacts of these tipping points. In this talk I will describe recent published work on interacting uncertainties between tipping points in the climate system alongside ongoing work to understand the economic impacts of tipping point uncertainties.

Jonathan is a Research Officer at LSE working at the intersection of climate science and economics. As part of the ClimTip Horizon project, he researches the economics impacts on climate tipping points as well as the use and design of climate model ensembles for decision-making. Jonathan completed a PhD focusing on global climate model representation of the Southern Ocean, based at the University of Cambridge and the British Antarctic Survey. The focus of this research was on the analysis and intercomparison of global climate models in the CMIP6 ensemble under  control and forced scenarios. During this time he also worked on uncertainties in climate tipping points at the Existential Risk Alliance, and international climate diplomacy and UK heat supply at the UK Climate Change Committee.  He holds an MMath (Masters in Mathematics) and an MA (Masters of Arts in Natural Sciences) from the University of Cambridge.
