Abstract

Korenaga takes issue with our proposal that intermittent plate tectonics provides a solution to the thermal catastrophe paradox, arguing that the heat flux in the absence of plate tectonics is too high. We show that this flux is small enough and changes rapidly enough in response to variations in slab flux to produce a reasonable thermal history back to at least 3 billion years ago.
