      This is a 90% (very likely) range for the TCR according to AR6 Technical
      Summary: Based on  process understanding, warming over the instrumental
      record, and emergent constraints, the best estimate of TCR is 1.8 degC,
      the likely range is 1.4 to 2.2 degC and the very likely range is 1.2 to
      2.4 DegC. There is a high level of agreement among the different lines of
      evidence (Figure TS.16c) (high confidence). {7.5.5}

      Evaluation of the model using global criteria performance criteria (past
      trends + spatial pattern) Model with performance scores below 0.006 are
      considered as irrealistic.  This study is based on multi-member for each
      model, not on only one member. Wrt to the original article, we consider
      here only the performance criteria and not the combined criteria that
      takes also into account the independence.

      models lying outside the observationally-constrained 90% interval obtained
      by the method are considered as implausible. The 90% interval is [1.5 ;
      2.1]degC for the period 2041-2060 vs 1850-1900, SSP245. Multi-member
      ensemble mean is used in this study for every model. Note that this
      criteria is very strict and can potentially eliminate a large number of
      GCMs.

      CMIP6 models and clustering of errors into categories are provided by the
      author for Europe.  Based on the method of qualitative scoring in
      McSweeney et al. (2015) and adapted for CMIP6. The scoring has been

    comment:
      Domain is CORDEX-EUR. Data z500 is converted to daily anomalies and
      normalized by daily standard deviation. Data are then attributed to
      previously obtained Synoptic Circulation (SP) classes. Number of Synoptic
      Circulation classes is 43 (derived on daily ERA-Interim data, 1979-2018).
      For each model, 7 variables are computed from the attributed daily data.
      1) HIST - frequency of each SP-class (year through) 2) HIST_JFD -
      frequency of each SP-class (winter) 3) HIST_MAM - frequency of each SP-
      class (spring) 4) HIST_JJA - frequency of each SP-class (summer) 5)
      HIST_SON - frequency of each SP-class (autumn) 6) SEQUENCE - matrix of
      frequencies for the subsequent occurrence               of the pair of two
      synoptic patterns SPi?SPj. 7) PERSISTENCE - matrix of frequency for
      persistence of each                  SP-class for 1,2,3,.. N days in a

      For the performance criteria, we compute the spatial RMSE on the 12-month
      bias maps over the period 1985-2014. It means that we first compute the
      temporal average to obtain a mean seasonal cycle - 12maps- of the bias
      maps and then we compute the spatio-temporal RMSE. All the models are
      interpolated on the grid of the refererence dataset, and then a mask of
      the Mediterranean Sea is applied (no Black Sea). The reference dataset is
      a specific CMEMS product developed for the Mediterranean Sea,

      Warming classes are determined wrt an observationally-constrained range

      (in rev). The observational constraint is a global constraint on the GMST
      but it allows to constraint the regional climate warming. The 90% interval
      of future warming plausible range is [2.3 ; 3.3]degC The 50% interval of
      future warming plausible range is [2.5 ; 3.0]degC The best estimate is a
      warming of 2.8 degC Category definition (new since 5 jan 2022): Categories
      1 and 5 are considered as implausible by S. Qasmi. Category 2, 3, 4 are
      plausible. Class 1 is below the Q5 of the constrained range. Class 2 is

      For the Future spread, we simply compute the basin-averaged and temporal-
      averaged climate change response (annual mean) over the Mediterranean Sea
      (no Black Sea) for the period 2070-2099 wrt the present-climate 1985-2014
      period for the SSP585 scenario.

      The limits of the warming level categories (weak, medium, strong) are

    comment:
      From Figure 5. Model family tree for all 33 CMIP6 models, similar to
      Knutti et al. (2013). Models branching further to the left are more
      dependent, and models branching further to the right are more independent.
      The analysis is based on global, horizontally resolved tasCLIM and pslCLIM
      in the period from 1980 to 2014. Labels with the same color indicate
      models with obvious dependencies, such as shared components or the same
      origin, whereas models with no clear dependencies are labeled in black.
      Using this figure 5, we have put in the same family, the GCM lines that
      merge before the dashed line, that correponds to the independence shape
      parameter. We have given family names only to families with at least 2
      members. Note that we are not using the Figure 5 color code to determine
      the family. This leads to some surprise such as  Strangely, ACCESS-CM2 is
      in the same family as UKESM and HadGEM3, but not ACCESS-ESM1-5. This was
      confirmed as ok by the Australian group. Also the two FGOALS model are not
      belonging to the same family with this criteria.
