This is neat, but studies with the thousands of floater monitors have show that ocean surface temperature cannot exceed 30c, before wild convection cools it.

@hasmis not "cannot." Sea surface temps can, and have exceeded 30c. Simply put, it's a matter of how hot the troposphere gets:

The link explains better than I can. The sensors have only been in the ocean for the past 30-some-odd years, not all of planetary history. Yes, for this brief window of human monitoring, the temperature has not exceeded 30C, bit there is no scientific or physical law that requires that; it's the result of a complex set of other factors, all of which are changing.
