Did you watch the entire video? The last minute or so put things into context. It said that the glacier retreated more in the last 10 years than in the 100 years before that. I think that is a reason for concern and it is impressive, any which way you look at it.

How much did the glacier retreat 1000 years ago during the Medieval Warm Period? And how much did it grow back 400-500 years ago during the Little Ice Age?

100 years of data is not enough to understand what's really going on.
