Climate change has become an issue fundamentally shaping our societies, politics, economics and, most of all, our future. The course will provide insights into the science of climate change, its impacts and mitigation opportunities. it will explore the role of humans in present climatic changes, compare present climate change to past ones, and examine the possibilities for future climates. Impacts of climate change will be reviewed in an IPCC based risk framing, but impacts on our economies and societies will also be discussed. The course will place a strong focus on climate action and opportunities: the Paris Agreement, climate neutrality, and key mitigation strategies towards deep decabonisation. The course will pay particular attention to climate related issues that are presently contentious in our societies, including climate skepticism, migration, negative emission technologies, and necessary lifestyle changes. The course will involve theories and principles from a wide spectrum of disciplines, including physics, meteorology, engineering, architecture, environmental science, economics, physical, social and political geography, and policy studies.
