Here is the original example where I added : data_vars='minimal'.
```python
#!/usr/bin/env python3
import xarray
ds = xarray.open_mfdataset('example_jan.nc', concat_dim='Time', data_vars='minimal')
print(ds)
```
```
Dimensions: (Time: 1, nOceanRegions: 7, nOceanRegionsTmp: 7, nVertLevels: 100)
Dimensions without coordinates: Time, nOceanRegions, nOceanRegionsTmp, nVertLevels
Data variables:
refBottomDepth (nVertLevels) float64 dask.array
time_avg_avgValueWithinOceanLayerRegion_avgLayerTemperature (Time, nOceanRegionsTmp, nVertLevels) float64 dask.array

Here is how to reproduce the error : (the testfile is attached here [1.zip](https://github.com/pydata/xarray/files/1770670/1.zip) )
```
import netCDF4
import xarray as xr
print(netCDF4.__version__)
print(xr.__version__)
ds = xr.open_dataset('testfile')
ds.to_netcdf('outfile.ok')
ds.to_netcdf('outfile.not.ok', unlimited_dims=['datetime'])
```
And the ouput I get :

```
1256 try:
1257 # First try to use the new axis= parameter
1258 return squeeze(axis=axis)
1259 except TypeError:
1260 # For backwards compatibility
1261 return squeeze()
```
I added the `axis` parameter in xarray and this fixed the problem.
```
PYTHONPATH=$HOME/sandbox/dev/xarray python -c 'import numpy as np ; import xarray as xr ; test = np.random.random((1,10,1)) ; print(np.squeeze(test, axis=0).shape); print(np.squeeze(xr.DataArray(test), axis=0).shape, np.__version__, xr.__version__) '
