Global snow cover and sea ice waxes and wanes with the seasons, as the axial tilt of the Earth with respect to the Sun oscillates throughout the year. As can be seen in this visualization, the cycles of ice and snow are about six months out of phase between the Northern and Southern Hemispheres, since the north is tilted towards the Sun when the nouth is tilted away, and vice versa.
