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.
Ummm…. There’s people right here on lemmy saying the same dumb shit about summer. Don’t think for a second that lemmy doesn’t host some of the exact same idiots Facebook does.
Good news is that many instances on Lemmy are less tolerant to alt-right trolls and climate deniers. Best to use that report function so your admins, or even better, their admins, can snipe them.
We are all humans, we are all dumb. A smart human isn't one who knows everything, they're one who knows what they don't know and knows who knows that. And, ya know, defers to the people who know about things when they don't.
The only issue that really matters to me is climate change. Or maybe plastic.
But this is the same as the picture of the statue of liberty that is used to "debunk" sea level rise by showing the level at the same height, despite being taken 100 years apart. Were they taken at the same tide? Same time of year? Is there any other factor at play here?
This is a "shoe is on the other foot" moment, and we should be as skeptical of that which supports our beliefs as we are of that which contradicts it. Maybe especially so because confirmation bias is a hell of a drug.
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...
Climate Impact Documentation in Norway, Svalbard
Greenpeace documentation showing that glacier "Blomstrandbreen" has retreated nearly 2 km since 1928, with an accelerated rate of 35 metres lost per year since 1960 and even higher in the past decade. In the image, view of climate campaigner Truls Gulowsen on a speed boat going to a mine in Longyearbyen.
Greenpeace activists visited the glacier last weekend on the Rainbow Warrior taking pictures from the same locations to highlight the effects of global warming, which the group says is a threat to the future of the planet.
The Blomstrandbreen glacier has retreated by one and a quarter miles since 1928, according to Greenpeace. It was shrinking by 115ft a year in the 1960s, a rate which has risen.
Recent studies carried out by US researchers and reported in Science last month said that 85% of the glaciers they examined had lost vast portions of their mass in the last 40 years.
Keith Echelmayer of the University of Alaska at Fairbanks, who has carried out research into Alaska's ice streams and checked glacier thickness, said: "Most glaciers have thinned several hundred feet at low elevation in the last 40 years and about 60 feet at higher elevations."
There's a couple similar photos from 2022 posted to Reddit by the same photographer (meaning the same person posted these two, not that it's necessarily the same person who posted the one above):
For that to happen the carbon would need to be buried in the ground again, however
And it's possible that humanity has emitted so much and warmed the globe so much that we shift the global climate stability point to something else than was before. It's possible the new equilibrium over millions of year will be a warmer earth
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.
The boat in the old photo (from 1928, apparently) is casting a pretty good wake, and the man aboard is holding a tiller attached to a rudder. It's impossible to tell for certain with the low-res image, but entirely likely that one of those shapes in the boat ahead of him is an inboard engine.
The old boat also has a motor, note how it's still moving in the photo while the only person in it is in the back holding a tiller (and appears to be facing forwards).
Which no-one is using. It's the first thing I noticed. There's a man sitting in the stern with a tiller and rudder, but there's no visible means of propulsion, no other crew. Weird.
Edit: I zoomed in, and it's possible there is someone else in the boat, hard to see.
I mean anyone is free to try their hand at reproducing it better, I'm sure the spot hasn't changed that much since the modern one here was taken, and if it has, well it'll just make the comparison that much more dramatic.
Mountains of ice melt in the summer then the water refalls in the fall and winter as snow and freezing rain in truly apocalyptic amounts. Rebuilding the ice mountains to start the process over.
Given that the sun is up at roughly the same amount, and at the poles the sun remains consistently up or down according to the season, I think we can rightly assume these two photos are taken at least approximately at similar times of the year.
Also, are you trying to insinuate that 100+ foot tall glaciers are somehow "seasonal?" Because they aren't.
Glaciers actually do retreat and advance seasonally or on even longer cycles. Some have terminuses that move back and forth literal miles. One of the key indicators of climate change is the fact that globally, glaciers are retreating more than they're advancing on average.
I'm not your thread's OP but I want to know the same question (what were the seasons) because no, I don't know how fast glaciers reach that height either. Nothing about that implies denial of the validity, it's a question to help quantify the change. Varying 10ft between seasons means this is a massive change regardless of season. Varying 100ft, not so much. No, I don't beleive it'd actually be 100fr of change in 6 months, but I could see it being more than 10ft.
