D6.4 Synthesis report on ESM projections with and without mitigation pathways

1. Idealized pathways to net-zero and net-negative emissions (Jörg)

Idealized ZECMIP and overshoot experiments with NorESM2-LM, short summary of results of the 2 published papers with a focus on reversibility and impact during the overshoots.

2. CMIP6 Scenario simulations with overshoot

Short summary of Tilla’s work (Tilla, Laurent)

3. Ocean alkalinization3.1 Representation of alkalinity in ESMs ? (Albans paper, Alban)�3.2 COMFORT ESM simulations of SSP5-3.4 (emission driven) with and without OA as used for EMICs in WP5. Aim to include ensemble mean EMIC results. (Timothée, Jörg, Laurent)

4. Other ocean mitigation options : Ocean Afforestation

Short summary of Manon’s paper (Manon, Laurent)
