It is a great course on the Arctic and its consequences on the earth as it influences the Northern Hemisphere

I am from Canada's Arctic and learned more about sea ice formation because I am from an area of freshwater. It was interesting to learn about ocean salinity, reading weather maps, and learning more about other areas of the Arctic like Russia and Norway.

Really excellent professor that explains concepts clearly and concisely without necessarily needed a lot of previous information in order to understand. Truly one of the better courses I've taken thru Coursera.

I learned a great deal about the Arctic and enjoyed the lectures.

Очень интересный и крутой курс! Большое спасибо!

Excellent overview. Held my attention.

Good overview, well taught but perhaps a wee bit repetitious

lot of improvement needed
