Global warming update: hot with a lot of ice

B09B originally calved from the Ross Ice Shelf in 1987 and drifted round to the east of Mertz Glacier by 1992. It was grounded for many years and started moving in late 2009. - In mid-February 2010 B09B collided with the Mertz Glacier tongue – a section of the glacier that protruded about 100 km from the Antarctic coastline at about 145ºE. The collision precipitated the calving of another massive iceberg, C28, from the tongue, measuring 78 km long and between 33 and 39 km wide. This calving event removed about 80% of the tongue, leaving only a 20 km-long stub. The calving had been anticipated, as rifts cutting across the tongue had been developing over many years, but the timing and collision was not.

So the ice Turney says was from AGW in fact came from a calving event which occurred 26 years ago. This event had been well documented but there was no ice from this event in the area where Turney's expedition became entrapped in ice. Unfazed Turney continues:

I believe you are probably aware of a number of papers this year that show land ice on Antarctica is in decline and that only seasonal sea ice has been expanding, likely due to the increase in westerly winds and potentially because of the decrease in salinity.

This too is problematic. A 2012 NASA study by Zwally et al concluded that:

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 laser measurements of elevation change.

This mass gain was notably in East Antarctic where Turney's expedition was heading.

In addition air temperature over the Antarctic has not increased since 1979:

Sea surface temperature [SST] has actually decreased during this period:

So we have sheet ice increasing, air temperature constant and SST declining; all ingredients likely to lead to an increase in sea ice which has been occurring for many years without any contribution from AGW.
