Indeed. The relationship is probably indirect. Warming causing receding of glaciers and also lowering water levels (stronger than than positive impact on it by melting glaciers). I thought though that maybe melting of glaciers might reduce the sealing of water basins (lakes) serving as a source for the Rhine. Causing the water to seep into the lake bed.
