Climate Change: Tipping Elements

This lecture delves into the Shared Socio-economic Pathways (SSPs) and the implications of different emission scenarios on global warming. It covers the concept of tipping elements in the climate system, the importance of limiting warming to 1.5°C, and the socio-economic challenges for mitigation and adaptation. The instructor discusses the IPCC priority scenarios, the contribution of different emissions to global warming, and the expected warming under various scenarios. The lecture also explores the potential collapse of the Labrador Sea current and its impact on climate. Additionally, it addresses the urgency of reducing emissions to meet the 1.5°C goal and the historical trends in global fossil CO2 emissions.
