\begin{abstract}
The Historical Experiment (HE) data in the Intergovernmental Panel on
Climate Change (IPCC) Climate Model Intercomparison Project six (CMIP6)
should demonstrate that all submitted models accurately simulate the
climate of the recent past. I show: none of nine models analysed
accurately creates the known occurrence of ENSO events; no model agrees
with any other; and average aerosol levels of the South East Asian Plume
(SEAP), the South AMerican Plume (SAMP) and the West African Plume (WAP)
are too low. Additionally, the SEAP and the SAMP cause the global
temperature to rise in all nine models and the WAP in six models. Hence
these models and all others which cannot accurately portray the known
occurrence of ENSO events should be withdrawn from CMIP6 until they can
and use of the IPCC Assessment Report six (AR6) should be paused until
the effects of these aerosol plumes on the global temperature is
re-evaluated.%
