It's awful to see dozens of people running and knowing they're all gone. It wasn't even close. They were so small compared to that absolute FORCE .

Is it correct to say that the video looks far worse than it actually is ? As in, the dust/mud particles sprayed & floating in the air do not have the force to do harm beyond vision or breathing impairment, similar to the dust from a collapsing building, or the lead shockwave of a nuclear bomb detonation. Of course, it looks terrible, and certainly somethingbut its not a reason to perish as long as you can stay away f…

It literally completely wiped from existence hundreds of reinforced multistory concrete buildings.

It's much worse than you seem to think based on the videos.

Both figuratively and literally, this experience was the tip of the iceberg. Terrifying. People might think I'm crazy, but I'm choosing my retirement location 100% based on resistance to climate change. Local water, too much humidity for massive fires, too cold for insane heatwaves... you get it.

Which places have you found? I'm in Canada and figured most of the places are going to suffer more rain falling in the next decades.

Cities in the tropics at high altitude far from the sea like Bogotá, Medellín, maybe even Mexico City.

Maybe some moderately increased risk of extreme rainfall causing localised flooding, mudslides etc, but Bogotá in particular has an incredibly mild climate year round, and you're at 2600m so you aren't too worried about sea level risk.

As far as I'm aware basically no risk from hurricanes, tornados or anything like that. Biggest risk is earthquakes which is nothing to do with climate change and can be mitigated.

In fact Bogotá is a bit chilly so might be nice if it was slightly warmer.

For some reason people assume that climate change means you need to move closer to the poles, but moving to higher elevation is much better

Clearly you've never felt the full force of a 6' wave crashing down on you and rolling you in the surf, never mind a 100' wave. What a silly comment.

I haven't yet been able to properly internalize the horror of this scene. Maybe because we're exposed to so many images from disaster and action movies/videogames, I got somewhat desensitized to the "graphics", so to speak. It's like my brain is denial. At the same time, I know this is real and a tragedy in an unimaginable scale. Every "little walking figure" is a full human being with dreams, fears and a rich life s…

About 160,000 people die each day if less dramatically.

Probably not. Most alpine valleys were carved by glaciers and have a characteristic U-shaped profile. When you get a landslide into a glacial valley, it hits the relatively flat floor and breaks itself apart. The valleys themselves are usually wide enough that they don't dam either. The alps also have significantly less relief than the Himalayas. The valley where the floods occurred in Nepal has a V-shape, and the pe…

Didn't realize google earth's performance had gotten that bad, but yeah, you can clearly see the V shape there. You can see the U shape in the hanging valleys on the higher slopes as well as further up where the main waterway originates, but whatever form the lower regions might have had after the last LGM has been reshaped by erosion.

You might want to take an intense media break. I went to 4chan to find more videos of the event, something it's rather good for, and even those guys were largely shocked and flabbergasted at the scale of the carnage and destruction

any link or to way how to find it there? I though it will be in the current events but can't find it and search feature doesnt work edit: seems the only way to search the site is the google, this thread has few videos https://boards.4chan.org/pol/thread/541442303 https://boards.4chan.org/pol/thread/541527487/nepal-images

I was looking on /gif and you can just search the titles for nepal

https://apnews.com/article/climate-change-nepal-tibet-glacie... CCTV footage is there. Horrific scene. When you see it coming at you it’s already too late.

What was the comment of the form "climate change will manifest as a series of phone videos of disasters that get closer and closer until you're the one holding the phone?"

I have been trying to find the original source of this quip for a long time. It stays in my head but I don’t know quite where I saw it.
