One reason for this is that «global temperature» varies significantly over the months of the year due to seasonally varying Earth / sun geometry and the greater land mass in the Northern Hemisphere, so that any global average of absolute temperature, not anomalies, will be considerably higher in NH summer than SH summer, and this will be true even in an unchanging climate.

I'm very convinced that the physical process of global warming is continuing, which appears as a statistically significant increase of the global surface and tropospheric temperature anomaly over a time scale of about 20 years and longer and also as trends in other climate variables (e.g., global ocean heat content increase, Arctic and Antarctic ice decrease, mountain glacier decrease on average and others), and I don't see any scientific evidence according to which this trend has been broken, recently.
