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.
