In this lecture, I discuss some things we know on the Earth's climate in the past, in particular ice ages, what we think caused them, and some simple mathematical models that can be used to analyze this further. Global warming is not the main focus of this video, though I will say some words at the end on why it is extremely likely that the currently observed climate change is caused by human activity.
