So, the positive feedback between melt and velocities implies that more melt leads to higher velocities, which bring in more ice from cold regions to
warm regions which increases the melt and hence the velocity etc, with as a final result a rapid loss of ice and hence an enhanced increased sea level.

In theory,
warmer temperatures across the
region should be decreasing the snow pack —

A possible cause for the accelerated Arctic

The silicate + CO2 - > different silicate + carbonate chemical weathering rate tends to increase with temperature globally, and so is a negative feedback (but is too slow to damp out short term changes)-- but chemical weathering is also affected by vegetation, land area, and terrain (and minerology, though I'm not sure how much that varies among entire mountain ranges or climate zones)-- ie mountanous
regions which are in the vicinity of a
warm rainy climate are ideal for enhancing chemical weathering (see Appalachians in the Paleozoic, more recently the Himalayas).

Furthermore, even if the net meridional overturning circulation,

This chemical weathering process is too slow to damp out shorter - term fluctuations, and there are some complexities — glaciation can enhance the mechanical erosion that provides surface area for chemical weathering (some of
which may be realized after a time delay — ie when the subsequent
warming occurs — dramatically snow in a Snowball Earth scenario, where the frigid conditions essentially shut down all chemical weathering, allowing CO2 to build up to the point where it thaws the equatorial
