In this Climate Change lecture Prof. Stefan Rahmstorf deals with the impacts (with a focus on extreme events and Sea-Level Rise) and the possibilities for holding Global Warming below 2°C.
These lectures form part of a broader lecture course called World in Transition. It includes 11 themes, presented by the members of the German Advisory Council on Global Change (WBGU). This is a body of experts appointed by the German government and advising it on global change issues. http://www.wbgu.de/
