- **Transient behaviour of AMOC**. This group had two possible foci, the last millennium simulations or other Holocene transient runs. There is so far no multi-model paper focused on AMOC behaviour in all the past1000 runs. Elements of this research have been published elsewhere though (say in single model papers) and there are data availability issues. A paper comparing transient runs performed outside of PMIP to proxy data shall be worked on (led by UCL with MPI and IPSL involved). | - **Transient behaviour of AMOC**.
