I myself asked "What time of year was the lower photograph taken?" Then I realized I was being dumb, because if either photo was taken in winter time, we would see at least some ice in the water, if not a very large ice sheet.
Facebook comments: Well obviously it was taken in the SUMMER 😂🤣😆 Morons global warming is all fear mongering!
Yes Jim. It's very normal that entire glaciers disappear, regularly in fact, every year. You are so smart, much smarter than all of the scientists who are panicking.
A reverse image search revealed to me that there are a hell of a lot of copies of this image around the internet, but I can't seem to find any papers that provide background. I'm going to have to look again later, but if there's any other internet sleuths out there interested in figuring out the origins of these photos with reputable explainers, I would love to know more about this.
I'm always afraid of things like this that seem to confirm my biases without associated information to back it...
