WebDec 20, 2015 · Explanation: Perihelion currently occurs around 3 January each year. This is in the northern hemisphere Winter. The seasons are mainly due to the obliquity of the Earth 's axis of rotation, or axial tilt. At perihelion the Earth is about 147,000,000 km from the Sun. At aphelion it is about 152,100,000 km from the Sun. WebThe relationship between equilibrium and nonequilibrium responses and its implications for climatic sensitivity are discussed in the context of an empirical model due to Imbrie and Imbrie.
