All Scientists are Sceptics ~Professor Bob Carter

Whenever someone asserts that a scientific question is “settled,” they tell me immediately that they don’t understand the first thing about science. Science is never settled. Dr David Deming

Perhaps the most frustrating aspect of the science of climate change is the lack of any real substance in attempts to justify the hypothesis ~Professor Stewart Franks

Antarctic Temperatures inconsistent with the hoax of AGW

P1: Cold Enough for you?
P2: I think it's getting colder!
In a world that is warming,  at least according to the AGW Alarmists, the cooling of temperatures in Antarctica contradicts their hypothesis.

The American Meteorological Society publishes the Journal of Climate and in volume 25 (link) in a paper by Sinclair et at found that "Reconstructed mean annual temperatures show no significant change between 1882 and 2006..." and that "a cooling trend" is observed since 1979.

From CO2 Science: (link)

Sinclair, K.E., Bertler, N.A.N. and van Ommen, T.D. 2012. Twentieth-century surface temperature trends in the Western Ross Sea, Antarctica: Evidence from a high-resolution ice core. Journal of Climate 25: 3629-3636.

What was learned
Over the full length of their record, the three researchers say, with respect to temperatures, that they could find "no significant trends between 1882 and 2006." Neither were there any significant trends in either summer or cold season temperatures since 1958. However, they say there was "a decrease in cold season temperatures of -1.59°C ± 0.84°C/decade at 90% confidence (p = 0.07) since 1979," which cooling, in their words, was "coincident with a positive trend in the southern annular mode, which is linked to stronger southerly winds and increased sea ice extent and duration in the western Ross Sea," which they say "is one of the few regions experiencing a significant positive trend in sea ice and a negative trend in sea surface temperatures," citing Comiso et al. (2011).

What it means
Sinclair et al. conclude that "positive sea ice extent anomalies in the region adjacent to the Whitehall Glacier site, and cooler more vigorous meridional circulation in cooler months, may also be linked to lowered continental surface temperatures," but they indicate that additional data are required to determine the full extent of the recent cooling.
