You're making the mistake of thinking of it as one model. There are multiple different models involved in a climate simulation. Here we have the situation that when a bunch of mostly correct models run end-to-end, the final radiated heat is less than expected due to a cloud component of the simulation not working correctly - doesn't mean the whole set of models is wrong.
The ocean models that you then comment about seem to be accurate and we do have some evidence that the circulation in the Atlantic is weakening.
+4 in Britain would not be nice - large parts of the country would struggle. It would mean a significant increase in CO2 output as the amount of installed AC rapidly increased - typically we don't need it.
