And here's a five-second recap of what's happened at Alaska's Mendenhall Glacier in just eight years:
The below time-lapse video was created by Extreme Ice Survey, a Colorado-based, long-term photography project founded in 2007 by acclaimed photographer James Balog, whose work is showcased in the award-winning documentary "Chasing Ice."
Since installing a camera at Mendenhall in 2007, Extreme Ice Survey says the glacier has retreated more than 1,830 feet -- about one-third of a mile. Its abnormally fast retreat and deflation shows the effects of climate change in action, according to Extreme Ice Survey.
"Once flowing proudly across Mendenhall Lake, the glacier now takes a small piece of lake front real-estate far from where our cameras were originally installed, and even further from the view of the thousands of visitors who travel to see the glacier each summer," reads a post on Balog's Earth Vision Institute.
Mendenhall Glacier, located outside of Juneau, stretches for 12 miles and is home to some otherworldly ice caves.
