Spatio-temporal scales of the processes discussed in the present review. Short-term processes occurring at local to regional scales are the ones potentially triggering MISI. Heat transport from open ocean to the continental shelf also depends on the long-term meridional overturning circulation (dashed orange line). Similarly, short-term ice sheet dynamics, and their response to local forcing, depend partly on its long-term evolution. The difficulty for the modeling community resides in capturing the long-term essence of those processes, occurring at continental to global scale and short-term response occurring at local to regional scales within the same simulation. A trade-off between numerical model horizontal resolution and integration time is so far still necessary. Note that vertical resolution of numerical models is not mentioned but is essential to capture the continental slope and shelf oceanic processes (heat, salt and nutrient transport). No atmospheric processes are reported here but they are implicitly contained in the AABW formation, CDW intrusions, ACC position and meandering (winds effect, polynya opening, etc.) and in ice-sheet short and fast dynamics (surface mass balance processes) as described in the previous sections. Note that glacio-isostatic adjustment (GIA) and sub-shelf melting are to be discussed in upcoming reviews by Smith et al. (in preparation) and Whitehouse et al. (in preparation). Tectonism refers to volcanism and crustal deformation of timescales that are beyond the ones discussed in this review
