Today, we’re going to visit Siberia and take a closer look at how temperatures there (and around the globe) impact the way cultures, communities, and landscapes form. Air temperature plays a much bigger role than just helping us decide what we’re going to wear everyday, it dictates the kind of foods we can grow, how we build our cities and roads, and the kinds of industries that can even exist in a location. And in a region like Siberia, where it can get cold, like REALLY COLD, the air temperature has had an incredible impact on life. But before we end this episode we’ll warm up with a visit to Phoenix, Arizona to talk about how they too have to make a lot of decisions due to the extreme heat of a city in the middle of the desert.
