Earth is warming! But what does this mean for the nature around us? How are we as humans affected and why is it so hard to adapt or even stop it? In this course we will step in the shoes of scientists, businesspeople and policymakers to get to know more about climate change and how it interconnects all sorts of disciplines. We will understand why our climate system changes, dive down to coral reefs and feel the warming in the Arctic. We will use game theory to understand why we tend to overuse resources; and finally, we will become part of the United Nations Climate Change committee to discuss political actions. Accompany us on our journey and learn that changing the world is difficult but possible. Perhaps that change starts with you?
