Simply saying there’s more ice doesn’t attempt to get to the bottom of it.
“At the end of the last Ice Age, the air became warmer and carried more moisture across the continent, doubling the amount of snow dropped on the ice sheet,” Zwally said

Phew, nothing to worry about then.

(That second link defaults to showing Arctic sea ice, which is declining much more rapidly than the Antarctic sea ice is increasing.)

Subsea volcanoes. Nothing to do with the term I am not allowed to use. What a relief.

Unless the average geothermal heat flux is changing (and nothing about your link suggests this), this has been constant over the time spans in question and changes would be localized and temporary. Mt Erebus and its lava lake have been known to modern science for almost 200 years. The link you sent is talking about glacial motion and to what extent they've been under modeling contributions from meltwater from that existing geothermal effect that is reducing friction with the ground.
Even if that weren't the case, this is simply an article about air temperature. It broke the known record by a full degree celsius in the backdrop of massive, global record heat record setting as part of a long term trend.
Leaving that aside, what point are you trying to do with your comment? Do you think the southern polar ice sheet is melting from volcanoes, or getting larger?

Further, the submitted article here directly addresses it
"Schaefer said the temperature of the peninsula, the South Shetland Islands and the James Ross archipelago, which Seymour is part of, has been erratic over the past 20 years. After cooling in the first decade of this century, it has warmed rapidly.:

#9As a lay person I find it really hard to understand the significance of this single days temperature reading. It sounds alarming but I have no idea how to view that single data point. I wish they'd go into more detail in explaining that in these sorts of articles.

The point I'm trying to make is the Antarctic isn't melting, and it's in fact, growing in ice extent.
However, you can make a headline out of tiny regional fluctuations and puff it up to be more than it is. I'm not impressed that a record from Antarctica was broken (1 degree warmer than 1982? Yawn). How long have we had stations in this particular location? 40 years? 50 years?
Meanwhile you've got sensationalist headlines like in the Daily Sun: "Antarctica is hotter than SPAIN this week as mercury hits 69F for first time"
Which is blatantly false. It's a single data point on a massive continent that is obviously not 69F across the whole island, nor is it a sustained 69F. I have a big problem with people blowing out of proportion every individual data point in the massively complex climate system of the planet earth. How many points on the earth experienced record cold on the same day? Quite a few!
