One of the thorns in the side of the theory of Anthropogenic Global Warming has been Antarctica, which has given conflicting signals over the past few decades. In fact, one previous study:
...even suggested that parts of Antarctica were cooling in recent decades while the rest of the globe was warming.
However, the results of the most recent surveys are unequivocal:
Warm temperatures melted an area of western Antarctica that adds up to the size of California in January 2005, scientists report [see yellow and orange area in above figure].
Satellite data collected by the scientists between July 1999 and July 2005 showed clear signs that melting had occurred in multiple distinct regions, including far inland and at high latitudes and elevations, where melt had been considered unlikely.
One by one the deniers counter-arguments are being answered.
