In this course, we will explore Earth's climate in the past, present and future. We will cover what climate is, how it changes on timescales of seasons to millions of years, and how it's expected to change in the future. Various components of the climate system including the oceans, atmosphere, and ice sheets will be discussed here. We will also explore how records of past climate, such as ice cores, tree rings, and corals, can tell us about Earth's climate in the past and how they can inform our predictions of the future. This will primarily be a lecture-style course with several interactive components.
