Romero et al present an ice-free and paleo sea level chronology for James Ross Island in the northeastern Antarctic Peninsula area. They found that the advance of the local ice cap happened sometime after 40,000 years ago, and this implies a period of retreated ice in MIS 3.

A robot swarm is on a mission to map #Greenland’s perilous #icesheets
The fleet of drones, subs and sensors will map ice melt to forecast #climate #tippingpoints
Data from expedition funded by #UK’s secretive new inventions agency, will feed into climate models. Idea is to forecast when #ice melt will tip climate-regulating ocean currents into shutdown, and try to develop early warning system that would let humanity know when #glaciers are changing

Sea level doesn’t rise at the same rate everywhere – we mapped where Antarctica’s ice melt would have the biggest impact
When polar ice sheets melt, the effects ripple across the world. The melting ice raises average global sea…

Isostatic depression (Glaciology 🗻)
Isostatic depression is the sinking of large parts of the Earth's crust into the asthenosphere caused by a heavy weight placed on the Earth's surface, often glacial ice during continental glaciation. Isostatic depression and isostatic rebound occur at rates of centimeters per year. Greenland is an example of an isostatically depressed ...

There is always debate of the archeological sites in the Americas that are older than 13 ka, but years ago they found evidence of people in Yukon from before the LGM. Why is this not talked about? The age here (41 ka) provides plenty of time to traverse the ice free corridor.

McCormack et al make an assessment of predictions of ice loss from Antarctica, and state that the current models are likely provide accurate projections for the next 30 years, before completely diverging by 2080.
They hope for more model improvements, but from my experience it is incredibly difficult since collecting the data that would help with this (for instance, gathering high resolution subglacial topography and basal conditions data) is extremely expensive. Most governments are cutting funding now.
This doesn't even get into the computational challenges of properly modelling the ice physics. The approximations that we often use do not properly capture the subtleties of ice flow and calving, but the full equations are difficult to solve and are computationally intensive. It is a big challenge.

How is this for a feedback loop?
Ice sheets build up during a glaciation lowering global sea level → reduced water load leads to increased mid ocean ridge volcanism after a 10-20 kyr lag → volcanism releases iron in the ocean → iron causes plankton blooms → atmospheric CO₂ goes down → ice sheets build up
