during the southern winter (march–september), the south pole receives no sunlight at all, and from may 11 to august 1, between extended periods of twilight, it is completely dark (apart from moonlight). in the summer (september–march), the sun is continuously above the horizon and appears to move in a counter-clockwise circle. however, it is always low in the sky, reaching a maximum of 23.5° in december. much of the sunlight that does reach the surface is reflected by the white snow. this lack of warmth from the sun, combined with the high altitude (about ), means that the south pole has one of the coldest climates on earth (though it is not quite the coldest; that record goes to the region in the vicinity of the vostok station, also in antarctica, which lies at a higher elevation). temperatures at the south pole are much lower than at the north pole, primarily because the south pole is located at altitude in the middle of a continental land mass, while the north pole is at sea level in the middle of an ocean, which acts as a reservoir of heat.

surprisingly, if you run through the path twice, i.e., run from north pole down to south pole, jump back to the north pole (using the fact that north and south poles are identified), and then again run from north pole down to south pole, so that "φ" runs from 0 to 4, you get a closed loop which "can" be shrunk to a single point: first move the paths continuously to the ball's surface, still connecting north pole to south pole twice. the second half of the path can then be mirrored over to the antipodal side without changing the path at all. now we have an ordinary closed loop on the surface of the ball, connecting the north pole to itself along a great circle. this circle can be shrunk to the north pole without problems. the plate trick and similar tricks demonstrate this practically.
