It’s the usual precautionary ‘wait until you know the consequences before you go warming up the planet’ parable which you probably don’t need to hear again.  According to the Independent:

An army of shell-crushing crabs is poised to invade parts of the Antarctic Ocean that were off limits to the crustaceans for millions of years because of the intensely cold water.

And it seems all the slower animals who currently live in those crab free Antarctic waters are going to be eaten as a result.

Sea-surface temperatures off the western Antarctic Peninsula have risen by 1C over the past 50 years, more than double the global average.

And then, once the crabs have moved in and start to eat all the other shelled critters that had previously been safe, the whole balance of the ecosystem changes.
