Fakultätskolloquium - 1.5°C versus 2°C: Integrated Assessment Modelling and Cost-Effective Climate Protection Strategies on a Global Scale
Abstract: The Paris Agreement’s central aim is to strengthen the global response to the threat of climate change by keeping the global mean temperature rise well below 2 degrees Celsius (relative to the pre-industrial level) and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius. In order to determine cost-effective climate protections strategies subject to climate constraints (such as 1.5°C or 2°C), Integrated-Assessment Models (IAM) are frequently applied. The presentation will provide an insight into the state of art of integrated assessment modelling as presented in the 5th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5). In addition, Professor Bruckner – who has been coordinating lead author for the chapter on “Energy Systems” in the IPCC AR5 – will describe the challenge that is associated with moving from 2°C to 1.5°C in terms of feasibility and costs.
