Northern Climate vs Southern Climate

The South and the North have different climates. The North is much warmer during the summer months than the South during the winter months. During the summer months, the Arctic is suffused with sunshine and is relatively warm. The  North is known to be rich in vegetation and wildlife up to latitude 65°N, and temperatures above 30°C   north  of  latitude 60° are not uncommon in the summer months. None of this can  be said about the South. Temperatures below the freezing point throughout the entire year ensure that the Antarctic remains covered in perpetual ice. The South has reportedly no significant vegetation nor wildlife beyond latitude 60°. During the winter solstice, the temperatures at latitudes around  60°S may climb only  a few degrees above the freezing point - tropical conditions for penguins and seals, too cold for humans. Comparable latitudes in the North bathe in sunshine and warmth during the summer solstice. So what causes the climatic differences? 

Picture above shows the Sun and its light body on December 21, winter solstice; and the Sun on June 21, summer solstice.  During the summer solstice, the Sun rises in the sixth, the highest portal. During that period, the Sun is at its highest point. Accordingly, the light from the Sun comes in more steeply than in other months and thus the Sun radiates more warmth in the North. The opposite is the case during the winter solstice: The Sun rises in the first and lowest portal, and is at its lowest point on its orbit. Accordingly, the sunlight comes it at a sharper angle, which has the effect that it does not provide the warmth necessary for the ice in the Antarctic to melt and for vegetation to flourish south of  latitude 60°.
