The models are plenty good enough now to tell us that CO2 and other

Even the canonical deniers for hire admit that - at least when they are
being scientific. You cannot balance the Earth's global energy budget
without including greenhouse gas forcing after the 1970's.

Back in the mid-noughties the Met Office published a document about
global warming (as it was called then), and in its many pages there was
a diagram illustrating 12 forcing mechanisms and the then current state
of scientific knowledge of each one. Only one of these was shown as
being understood to a 'good' level. That was CO2, of course. Eight, yes
*eight*, of the other levels were shown as having *very low* levels of
understanding. In scientific terms, if one wants to construct a model of
climate and its forcings, the above essentially means that the inputs to
the models are little more than a guessing game, and it is small wonder
that they have predicted nothing - not even the current thermopause.
