Hmm...I can't seem to reproduce the issue. Are you sure you are using the latest release of xarray? ``` In [1]: import gcsfs; import xarray as xr

In [2]: gcs = gcsfs.GCSFileSystem(token='anon')

In [3]: mapper = gcs.get_mapper('gs://cmip6/CMIP/NCAR/CESM2/historical/r1i1p1f1/ ...: Amon/tas/gn/')

In [4]: ds = xr.open_zarr(mapper, consolidated=True)
