Its amazing to see this at first hand, a natural phenomenon however it has been proven that the retreat is moving faster than what it should. I'm not sure if humans are actually getting the message of Global Warming, that it's already here and its happening now. Soon we will no longer see those things you experienced, everything we take for granted is disappearing before our eyes, just like those glaciers. We can try and pass the blame but it wont work for too long.
