In the context of the Intergovernmental Panel on Climate Change (IPCC) Special Report on 1.5°C, the JPI Climate Action Group "GHG emissions, removals and management systems" organised a workshop on 27-28 March 2019, in Brussels, with the aim to explore the state of play of key models (central to the provision of analysis of the drivers of climate change and response options to achieve policy goals as established in the Paris Agreement), including how models are linked and gaps that may exist between them.
The first day of the workshop focused on high-level presentations followed by panel discussion and open floor consideration of the issues identified, with the objective of identifying options and steps to address these.
Day 2 focused on practical issues and options to address the outcomes from day 1. It has also explored the development of key European research capacity, including the further development of JPI Climate Action Groups and Knowledge Hubs.
The following topics were identified by the workshop participants as needing further development:
o The definition of global temperature
o The consistency between models and countries’ estimates of CO2 fluxes
o The role and performance of reduced climate models
o Carbon cycle and Earth System feedbacks
o Climate sensitivity
o Reducing global temperatures after 2050 through the large scale use of BioEnergy with Carbon Capture and Storage (BECCS)
The proposal for JPI Climate Knowledge Hub on Carbon Neutrality and GHG Balance was welcomed by the workshop participants, who recognised this need and encouraged JPI Climate to set it up.
