Deep water warming is a secondary issue to where the already relatively warm water goes. The main concern regarding changes in the deep part of the Southern Ocean is the decline in bottom water production.

All of that is detail. If the planet was 10 degrees colder or 10 degrees warmer, all of that detail is secondary. Getting the basic level of planetary heat wrong on a global scale will lead to disastrously incorrect melt rate projections.

Any melt rate calculation based on a simple function or parameterisation of climate sensitivity will almost certainly be wrong, because this would ignore the complexity of the Earth system and the physics of the processes involved.

Fully agreed.
