THE ANTHROPOCENE: DETECTION AND ATTRIBUTION OF CURRENT CLIMATE CHANGES IN A GLOBAL PERSPECTIVE

This course aims to provide the tools to understand the climate system and the more recent changes through a global perspective. The more recent definition of a novel epoch, named "the Anthropocene", underlines the importance of the anthropogenic influence on the climate. The comprehension of these dynamics will give to the student the ability to better comunicate, promote and participate to the global discussion about climate changes.

At the end of this course, it expected that the student will have a clear comprehension of the meaning of the Anthropocene, defined as a novel epoch. Moreover, it is expected that the stundent will acquire the knowldege of the past climate dynamics and he/she is aware of the future scenarios provided by the climatic models.

This course is a required/elective course offered to students enrolled in the Master Degree in the Environmental Humanities. No prior background in the subject is required.
