Dude, somebody's been lying to you.
Look at this as
evidence that the ice cap is melting. And this from
RT:
The ice sheet of West Antarctica is diminishing faster than in
any other part of the continent. Some glaciers are shrinking by more than one
meter per year. At the same time, it accounts for some 10 per cent of the global
rise in the sea level. Understanding these processes is crucial for our ability
to predict future behavior of the ice flow, as well as the global rise in sea
levels as the climate continues to warm.
Over the past two decades,
satellite observations revealed consistent and substantial ice losses from
around much of Antarctica’s coastline.
“What’s particularly important is
that this spectacular valley aligns perfectly with the recordings of ice-surface
lowering and ice loss that we have witnessed with satellite observations over
this area for the last 20 years,” Bingham explained. [ Reply to This | Parent | # ]

Two problems - firstly it's not how fast it's melting that's the concern, it's
how that rate is changing. It's getting faster.
And secondly, the rate of melting is irrelevant if the rate of glacial flow is
increasing due to warmth. If icebergs are calving, who cares about a little bit
of melting. And the increasing warmth will both make the ice flow faster and
slow down the rate at which it is replaced. (If the rate of flow were increasing
due to more ice, we wouldn't be worried about global warming, though we might be
worried about global freezing...)
