Explore the complexities of global warming and climate change in this 44-minute lecture from Yale University's course "The Atmosphere, the Ocean and Environmental Change." Examine the Holocene epoch as a period of relatively stable climate, and investigate significant temperature and sea level fluctuations, including the Medieval Warm Period and the Little Ice Age. Analyze 20th-century temperature data, focusing on the strong warming trend from 1970 to present day, typically associated with anthropogenic forcing. Learn about the impact of volcanic eruptions on climate, such as the 1991 Pinatubo eruption. Discover how general circulation models simulate 20th-century climate using both natural and anthropogenic forcings, and understand their implications for recent temperature rises. Delve into topics such as the Year Without a Summer, recent climate amelioration, and observed changes during the 20th century.
