Climate Change and Its Effects

The video explores how global temperatures are influenced by latitude, sun angle, and ocean currents. It discusses the role of global winds in climate systems and introduces the Köppen-Geiger climate classification. Microclimates and their causes, such as urban heat islands and topography, are explained. The Holdridge life zones are covered, highlighting the importance of vegetation in climate zones. Finally, climate change predictions for US cities are discussed.
