Rock has about a quarter the specific heat of water (there are lots of kinds of rock, and it varies with temperature quite a bit.)
That's a quarter of the 4.18 J/g.K, not a quarter of the enthalpy of fusion.

Rock has very low thermal conductivity. That's one reason why land heats up at 2 to 3 times the rate of the surface of the oceans, so you go to the beach in summer.
Finally, experts in the field consider this (permanent ice melt) to be important. When you think they're wrong, surely the appropriate response is "what am I missing? What don't I understand?".
