Why is the climate of the Earth so important and how is it changing?

Global atmospheric circulation and ocean currents redistribute heat; natural causes explain past climate change over the Quaternary, evidenced by ice cores, tree rings and historical sources.
A focused answer to Edexcel GCSE Geography B Topic 1 (Hazardous Earth) on global atmospheric circulation, ocean currents and the natural causes of climate change, covering how circulation cells locate arid and wet zones and how ice cores, tree rings and historical sources evidence Quaternary climate change.
