Learning objectives

The course aims to provide students with the tools to deal with the classical problems or the most recent developments of paleoclimatology through the knowledge and understanding of the basic elements that allow the reconstruction of evolution of the environments and the climate of the past in a chronological framework.

Prerequisites

none

Course unit content

The course deals with: 1) Earth’s modern climate and processes; 2) the broad details of Earth’s climate history and in particular for the
past 250 Ma; 3) the main proxies used to reconstruct past climates; 4) the Greenhouse effect and role of the carbon cycle in Earth’s climate; 5) the role of ice sheets, ocean circulation, and orbital parameters and insolation on Earth’s climate; 6) changes in sea level related to climate change; 7) main climate characteristics of the last 2 ka
