For some context (which media rarely provide), Antarctica has about 12.3 million cubic km of ice sheet. The latest measurements I've seen show that between 2011 and 2014, the Antarctic ice sheet lost 125 cubic km per year.

Additionally, people have been noticing a loss of ice since at least 1932: http://trove.nla.gov.au/ndp/del/article/23150667

That didn't provide me any context at all. What are those numbers supposed to imply?

First, Antarctica is not "melting," and second it seems to have been happening for a long time.

Additionally, there has been no acceleration in sea level increases:
