Why is Antarctica melting more now than when the ozone hole was a major issue in 90s? That was centered on Antarctica and has been largely fixed I think. Why is this happening now and not then? Or is now because of then? Can anyone provide a clear answer? (edit: wtf? why would anyone downvote this? it's a legit and perfectly fair question.)

The ozone layer is AFAIK not correlated with heating. It blocks UV radiation which is harmful to humans and other living things but plays no significant role in temperature changes.

Your first link is broken.

Because conflating the ozone hole with global warming (two different and unrelated phenomenon) can be a legitimate product of confusion, but it's more commonly a denialist tactic on a par with "if evolution is real, why are there still monkeys?" See enough of it, you get uncharitable.

This is a very click-bait-ey title. Maybe it could be changed to something more appropriate for HN?

edit: This post used to read as "The melting of Antarctica was already really bad. It just got worse." It has since been changed.

That is ice area, most of it over water. The paper the article is referencing is about the thickness of grounded ice sheets and their stability, not the extent of sea ice.

You should really watch the special Vice HBO did on the current situation.

You're citing the levels of sea ice, which are at an all time high right now. But the sea ice is only around a meter thick max! Land ice on the other hand is far deeper, therefore containing more water. Sea ice form quickly, like on a lake during winter. Land ice is a lot thicker and harder to form, and we are losing that in Germany size chunks.

There is no link between ozone and global warming. No scientist has ever claimed there is. The problem with reduced ozone was increased ultraviolet radiation and health problems associated with that.

why would anyone downvote this?

Because the mechanism behind the melting is already explained in The Fine Article.
