I know it is not required by AGW. Stratospheric cooling IS, it cannot be produced by any other atmospheric process and is present globally, Show us different if you think that to be the case.
The GCMs produce a distinct hotspot in their forecasts. This is highly suggestive that they are not modelling atmospheric physics correctly, especially the water vapour feedback. Without the strong feedbacks assumed there is no large temperature increase. No catastrophe, no tipping point.
