Probably not. The Larsen B collapse was preceded by widespread surface melting across the shelf, which caused lots of crevasses to fill with water, driving them open, and the whole shelf pretty much shattered under the stress. We don't see that sort of melt on Larsen C - even though it's quite nearby, the climate is a couple of degrees colder.

A more probable (but still fairly unlikely) scenario is that this could destabilise the ice shelf over a longer timescale (maybe decades). Removing ice from the front would let the ice behind accelerate, stretch and thin, which makes it more vulnerable to calving again, and so forth.

The most likely outcome though is that there's no significant change to the ice shelf, except maybe the flow of the ice speeds up a bit, which is interesting glaciologically, but probably not something the rest of the world will get excited about.

Obviously, any and all of this could change as the climate continues to warm. If we start to see significant levels of surface melt ponding across the shelf, then we can worry.

Thanks for these facts! The article has somewhat of a different spin on it.

Well, there's not a whole lot of factual difference between "Big Thing Could Happen" and "Big Thing Probably Won't Happen", and I know which one I'd lead with if I was an editor. I don't think there's anything in the article which I'd disagree with on a scientific level.

And what if you are wrong about that prediction?
