remember that the Milankovitch-cycles-trigger-ice-ages hypothesis is basically just like that. A proposal to explain the glaciation cycles. The Imbrie's thought that they had it proven it, given the limited evidence available. However, Lorraine Lisiecky and Maureen Raymo clearly show the struggle to find the right wrench to hammer in the right screw. And they were certainly not the first. Things get worse if you compare the *soil samples* of the Hubberten paper with the glaciation isotope calendar. In other words if the evidence does not fit, the idea might be wrong.
