Just based on a cursory examination, you seem to be cherry-picking from your citation and omitting words that appear in that study, like “slightly”, to make it sound as if there was some sort of significant growth of the Antarctic ice sheet since 1979 that is now reverting to some stable state, which is not the case.
Looking at the data itself, Antarctic sea ice extent was pretty stable until the past two years, where it has fallen quite dramatically.[0] I think it is reasonable to express some alarm when you’ve gone from a trend of -0.12% per decade, to 16% below the 30-year average, in two years.

Decades of stability followed by sudden change is strong evidence against CO2 being the cause, because growth of that in the atmosphere is a very stable process. It suggests a different cause, which means it's natural, most likely related to undersea volcanism. In which case it's unlikely to be dangerous, unless you think this is some sort of freak event like an asteroid strike. But then you're not talking about climate change.
