After taking marvelous paleontological courses from the University of Alberta, I thought - this one cannot be bad. And I was right. As it is the case with other courses, this one has high-quality videos, and detailed lecture notes, which feel like as if you're reading an encyclopaedia. This course gives a nice introduction to the Arctic, its geographical and biological features, and then focuses on its climate, ecological niches, and climate change. Can't wait for the other courses in the series!
