During the last deglaciation, and likely also the three previous ones, the onset of warming at both high southern and northern latitudes preceded by several thousand years the first signals of significant sea level increase resulting from the melting of the northern ice sheets linked with the rapid warming at high northern latitudes (Petit et al., 1999; Shackleton, 2000; Pépin et al., 2001).

If we start out with a balanced system which contains frozen water at the poles, the mid to high latitudes begin to thaw, triggering soil greenhouse gas feedbacks (permafrost thaw and following oxic and anoxic sources add to the greenhouse gas budget), a chronic linear process (which helps to accelerate changes of the equilibrium state, reduces the ability of the atmosphere to break down greenhouse gases — less hydroxide radicals).

In that case (along with greater precipitation, and the precipitation belt moving to higher latitudes), there could be more snow in the winter & greater melting in the summer (in higher latitudes), while I'd think the lower latitudes (with less precip) and the local mean temp being higher, would melt the glaciers faster, without adequate snowfall & low winter temps to slow this glacial decrease.
