Well, it is the holidays now. And so, because I'm super lazy, to ease you guys into the topic of the North Pole, here's a video for you to watch! It basically shows us how the ice extent has changed from September 4th of '09 to January 30th in the Arctic Circle. The problem with this video is that it doesn't tell us the starts and ends of the winters and summers. But despite its ambiguity, we can still examine this video and hopefully, a few questions will come to mind while you guys watch it.
While watching this video, take note of the ice around Greenland and the islands of Canada. Also, note that while the ice in the Arctic Circle seems to retreat quite a bit at some point, the extent of ice also seems to be regained by January 30th (the end of the video). So what purpose(s) does this video has? Or is it absolutely rubbish and useless?
This video is from NASA. Read the youtube video description. Please do comment and tell me what you think! :)
