The climate emergency is an existential issue that we need to engage with at many levels. As a beginning we need to start educating ourselves about the climate. But how does one think about such a vast and complex system? In this course, we start from scratch and first grasp the various foundational physical concepts that are needed for a grounded understanding of climate change. We’ll then consider the earth’s climate as a complex, interconnected system and understand how climate scientists view it, using a framework of feedback loops and tipping points.
