I'd like you to show some support for either statement.

Here are some photos showing a buttload of ice lost from Antarctica
in 2002:

If there has been a gain since, it is doubtful that it has made up f
or what was lost.

Ok, you provided that support with your link.

And I pointed out that wasn't so, concluding:


Since the article does not quantify any gains at all in any part of
Antarctica, it certainly does not support your claim of a net gain.

No honest person reading and understanding the article would claim
that it does.


However, if I am reading the abstract of this paper correctly,
(Note it is in .pdf format)

http://www.igsoc.org/news/pressreleases/Zwally509.pdf

There was a net gain of ice in both Antarctica and Greenland
over the period of the study, 1992 - 2002. Averaged over that
ten year period the gain was 27 billion tons per year (Gt/a).

The net gain in Greenland was due to a gain in the interior
despite a loss at the margins. In Antarctica there was a net
loss on land net gain in sea ice.

I don't know if that data includes the March, 2002 collapse of
the Larsen B ice shelf, which was a loss of about 500 Gt.

I'll check with one of the authors to see.

I've also found a lot of information indicating net losses of ice
in the Arctic, and a net loss in the world's glaciers, but
information
on the former is not easily converted to net mass so I'm still not
clear on the recent net change, if any, in the global ice inventory.
