Can more experienced people describe how to verify this video as non-AI generated? Is there a scientific source in Greenland or Denmark that tracks such incidents? Or could satellite passes before vs after confirm what happened?

It is the work of but a moment to check for trustworthy sources. It's sad that this skill seems to have been lost. https://eu-space.europa.eu/components/earth-observation-cope... https://www.bbc.com/news/videos/cdx7lg950gdo

Earlier quoted context omitted.

Freezing point of water changes with salinity and impurities. By definition a liquid cannot be below its freezing point until it has completed its phase change.

Superheating, too, and that's something that can happen in a microwave, occasionally causing severe burns when superheated water flash boils. AFAIU, it's the same phenomenon--lack of nucleation sites to kick-off the phase transition.

Does that mean every TTT diagram is wrong?

Nevermind I just learned about CCT diagrams. I guess having only one year of materials engineering means I should STFU. :)

I would have thought it would generate enormous wave, but that's clearly not the case. I think some of the biggest waves was generated by a mountain sliding or collapsing in the sea. I expected something similar here. Anyone know why not?

It is not a very energetic event for its size. The iceberg is floating, it can't accumulate a lot of potential energy before flipping, so when it happens, there is not enough to make big waves. The center of gravity of the iceberg barely moves. A mountain sliding into the sea is different, these higher up rocks have a lot of potential energy, that convert into kinetic energy as they fall, which is transferred to the…

Here's an excellent example of the latter, from a short ways up the BC coast from me. Not caught on film, but found later by heli pilots, and on seismic data: https://hakai.org/stories/the-big-slide

Especially the spine. If you had shown me a portion of the video with that thing moving as such, I would have believed it to be some leviathan. Which brings us to the video itself - horrible. Presumably the original sound was recorded, because we hear it under the music. Just let us hear the sound! The people watching this video are people who appreciate nature, not people who need a dramatic soundtrack to be enterta…

Thank you!

Beautiful and scary at the same time. Almost like the iceberg was a planet on its own with mountains, valleys, crevices. Then everything goes haywire. The fall of a majestic titan. The destruction of a world.

There’s also something very organic about it. I had to keep reminding myself that it’s “just ice” and not a living being.

The stuff of legends...

Divest from any kind of S&P500 or cool tech stocks. Invest in renewable energy projects. The US government is failing you, only money talks.

Money and utility are often uncorrelated. Many solar panel companies went out of business in the last few years because solar panels are so cheap.
