Its a movie about global warming and how it effects the glaciers but it really focuses on pictures and time lapses taken by James Balog and they use those to show the effects of global warming.
Its on netflix and is a little longer than an hour. I strongly recommend taking the time to watch it. Even if you don't care about global warming, still watch it just for all the amazing pictures and an awesome story about a photographer.
