This gigapixel shot of Mt. Everest shows global warming effects

Via Redorbit we learn of a very cool super-sized photo of Mt. Everest:
Filmmaker David Breashears has created a spectacular, two-billion pixel zoom image of Mount Everest to show the effects of climate change in the Himalayas.
The interactive photograph reveals stunning details of the world’s highest peak, allowing viewers to ‘navigate’ around base camp and the mountain.
Breashears captured 477 individual images to compose the gigapixel panorama of the Khumbu glacier from the Pumori viewpoint near Mount Everest. The images were obtained this spring from a vantage point above base camp through a 300-millimeter lens.
The photographer says he’s found evidence in the photo of climate change’s effects. From the Guardian:
By comparing his panorama with photographs from the 1950s, Breashears has been able to pinpoint just how much ice is gone from the mountain: “There are 49,000 glaciers in the Himalayas and most are showing a dramatic and accelerated melt rate.”
NPR’s All Things Considered has an interview with the photographer as well.
I’ve taken a series of screen captures below of his photo to show you some base camps for mountain climbers, circled in red, and how you can zoom in and see them in incredible detail.  The circle is very small and to the right in the first photo below.
