Sorry cjameshuff, what you said makes perfect sense, but I worded my question badly. My fault.

I should have asked: how do we account for the faster than expected rate of surface cooling? How did the initial insulation of rock appear so fast?

As I understand it (and this is where I may be going wrong):

1. We used to think the surface of Hadean Earth was hot.
2. We now have reasonable evidence to think that it might have been cooler.

Do you know what we've changed in our models to accommodate (2), instead of (1)?

Or is this still a matter of dispute? I haven't gone and blundered into ATM have I?
