> You can argue with the author of the study saying that but I can't see an issue with an article reporting that they did, if that's what actually happened.

I think that's kind of the point: nobody knows if that's what actually happened and the study doesn't show any information to support any specific theory. I could be that (though I think it would be unlikely as we'd have probably seen a real steady decline in the ice sheet and not an up and down up), something else that is still concerning but not as severe, or maybe something that we didn't now before and is not as concerning.
