Climate: A Very Short Introduction considers all aspects of the global climate system, exploring and explaining the different components that control the climate on Earth. Climate affects everything we do in life, from the clothes we wear to the illnesses we might catch. How does energy reach the Earth? How does the ocean–atmosphere system redistribute energy around the plane? What is the relationship and what are the differences between climate and the weather? Climate affects life on Earth and human settlements in many different ways. Humans have to live their lives aware of the risk of cyclic and quasi-cyclic features of climate such as the Milankovitch cycles and El Nino.
