Antarctic ice most resilient in recorded history.

In Geophysical Research Letters, Tedesco and Monaghan published an article observing that the amount of melting ice in Antarctica between October 2008 and January 2009 (the most recent local summer) was the lowest figure in the recorded history - i.e. from 1980:
An updated Antarctic melt record through 2009 and its linkages to high-latitude and tropical climate variability
World Climate Report notices the deafening silence about this record, so different from the loud claims about a melting Greenland.

Right now, the Antarctic sea ice area remains slightly above the normal: the anomaly is positive. The corresponding anomaly is strongly negative in the Arctic region, although the anomaly was even further from zero one year ago.

Meanwhile, El Nino is underway and its positive impact on the global mean temperature may be seen. RSS shows the September 2009 anomaly at 0.476 °C which is a whopping 0.206 °C warmer than August 2009 and the highest reading since January 2007 when the figure was 0.592 °C.
