During 2003 to 2008, the mass gain of the Antarctic ice sheet from snow accumulation exceeded the mass loss from ice discharge by 49 Gt/yr (2.5% of input), as derived from ICESat [email protected] measurements of elevation change.
The net gain (86 Gt/yr) over the West Antarctic (WA) and East Antarctic ice sheets (WA and EA) is essentially unchanged from revised results for 1992 to 2001 from ERS radar altimetry.

Zwally goes on to say that “a slow increase in snowfall with climate warming, consistent with model predictions, may be offsetting increased dynamic losses.” But, of course, we don’t know how these rates of accumulation and melting compare to previous decades, so this is pure speculation on Zwally’s part.

There is nothing to suggest that this is not a normal, natural process seen many times in the past.

So, in Antarctica, we have:-

Increasing ice sheet mass
Advancing glaciers
Increasing sea ice
Global warming anyone?
Essentially, global temperatures have temporarily peaked, due to El Niño and the Decadel Oscillation and the planet is now entering a cooling phase. I suggest you sort out your central heating and buy a few more long woolly jumpers.
