There is a difference between global mean and local trends
What is often forgotten by many posters of all climate persuasions is that though the trend in global mean for temperature can go in one direction because a changing climate produces local variations that can in turn change currents and winds such that local a regional climates might trend in the opposite direction. Given that the bulk of landmass is in the Northern hemisphere and ocean and land have very different specific heats it is absolutely to be expected that there will be differences between Arctic and Antarctic trends in mean temperatures over certain periods.
