Climate Dynamics 38: 57-73 reported by CO2 Science.
The authors say that in the Southern Hemisphere there has been a modest increasing trend in sea ice extent (SIE) around Antarctica over the era of satellite coverage, citing the studies of Watkins and Simmonds (2000), Zwally et al. (2002), Parkinson (2004), Turner et al. (2007) and Comiso and Nishio (2008).
What it means
Noting that "southern sea ice has shown modest increases and established
new record ice coverage in the summer of 2008 by a wide margin," Pezza et al.
conclude their study by rhetorically wondering how this "peculiar
behavior" meshes with the theory of currently-unprecedented
anthropogenic-CO2-induced global warming.
