Here's a public versions of their nature comment written by the same authors. I should have linked to that instead of the original paywalled version but all these versions are making the same argument, presumably with sightly different wording for copyright reasons:

If you're claiming this material is "climate change isn't real" then look into who the authors are.

The topic at hand is climatologists changing their minds about basic variables despite decades of making predictions with 100% confidence. The fact that their latest models are totally unrealistic, by their own assessment, is further evidence that the science here is seriously flawed and subject to major revision, still.

Alright so the ipcc makes multiple projections, with some being "hot", in the sense that they are worse than their other predictions. I think they made like 6 predictions last report.

This papers is just arguing that the "hot" predictions should be less intense, because they are not very good at reproducing some specific past dataset.

That has nothing to do with a problem with hot models - it's a slight modification to them.

You seem to be arguing in bad faith. Your article even seems to imply that the hot models are fine with predicting present data, just jot the data of the last ice age. Who cares? What has that got to do with anything? No one is only looking at the hot model!

The article says this: many of the models are getting hotter with time in ways that are clearly wrong, but climatologists routinely use them anyway out of some misguided belief in "model democracy" i.e. that all models are equally valuable and correct even when they disagree strongly with each other so should just be averaged together. It's pointed out that this undermines vast amounts of the supposedly settled science.
