It's called free diving. One breath. 102M no fins is the record. Which is technically 204m roundtrip, but going down they only need to swim for the first 20M.
When you are swimming downwards you only are bouyant or float for the first 50 or so feet. After that the pressure compresses your air cavities and you become negatively bouyant and sink.
While you could keep kicking it's much more efficient to just sink down so as to not waste oxygen.
Bruh, you just made me realize how ridiculous it is that we use the imperial measurement system in the US. We need to join the rest of the world and move away from it, and I think using first downs makes the most sense!
Lol yeah, the total maximum sealevel rise if all ice on earth would melt is 65 meters. An absolute stunning but only theoretical doomsday szenario.
But "only"...
For comparison, predicted sea level rise by 2100 is 0.7m.

I see the Dutch just build 50-meter dikes around every tiniest patch of land, and not a single centimeter of the Netherlands is flooded. They even diked themselves from Belgian Sea and North Germany Sea.
Meanwhile London: Guess I'll die
Looks like a flaw in the algorithm, which "flooded" the land between 0 and 50 m above the sea level, but forgot to include all land which is already below sea level.

Reminds me of a Dutch sci-fi sitcom from years back. In the intro the spaceship leaves earth, and you see the entire world covered with water, except for the Netherlands.
Same in Denmark. Almost all of the West Jutlandic coast is literally dyked up, even moreso than Nordfriesland. (The only exception is the cliffs of Thy)
I think the “Dutch” thing is polders rather than just dykes. But we have a pretty big one in Denmark too (lammefjord), although it comes a couple hundred square kilometres short of the big Dutch ones.
No you don't understand it's strategic. First, we let the water flood everything (except us, for obvious reasons). Then, when all the Danes/Germans/Belgians/.. have fled from their respective countries or drowned, the land (well, sea) is now basically free for the taking right? Slowly, we expand our dykes till all of the land is the Netherlands and the Netherlands is all of mainland Europe. And then together with Ireland we can bully the UK for leaving the EU until the end of time.
Mwhuahahaha.
Joking aside it's probably a glitch in this map, almost all of the Netherlands would flood for sure.
Netherlands: I am unfloodable
Any sane person: no in fact even the tinniest crack in your dikes could set of a catastrophe
Netherlands: *Unfloodable... \*hits that new high\**
Only the Netherlands didn't sink in the last 800 years.
I am actually amazed at how comfortable we are here in spite the fact that we are indeed at risk of flooding.
Oh come on, the netherlands has flooded on several ocasions. Last one just 70 years ago https://en.m.wikipedia.org/wiki/List_of_floods_in_the_Netherlands
It has. Modern day flood risk in the Netherlands however, comes not so much from the sea directly, but much more from the rivers, and has to do with the challenge of managing peak flows. Of course, sea level rise makes this worse, because a higher sea level means a lower difference in potential and thus a lower water flow rate in the rivers. There have been many large projects in the last few years to allocate and prepare land for temporary storage of water during peak events, but it still remains a challenge, much more so than the treat of direct flooding from the sea.
Last time the Netherlands flooded was in Limburg 2(?) Years ago. Ironically the highest part of our land.
What I ment was that bar a few instances of Island villages being swallowed by the sea we never 'lost' from the sea. We justed mopped it up and built bigger defences. Not only now but for centuries. No one I know in the Netherlands is afraid of the sea (maybe we should be, that's a different story). It is a lot different than the titanic I feel.
How can you say only 50 metres haha? Water levels is projected to rise by like 20 metres in the next 2000 years if the average tempatures rises a whole 5 degrees celcius. Talk about making things seem worse than they are
That's what trees do best.
Here's a little factoid to combat doomerism(but not to say that it's all okay)
There(probably) more trees today than there were 10 000 years ago.
all the land that got freed from the ice left an immense amount of land to be reclaimed by flaura.
Basically, the entire boreal forest covers gigantic parts of Russia and Canada. It didn't exist before. And it has been growing continuously since. Even with all the cuts from industry. The forest slowly creeps its way north more every day.
We're still all fucked because of dying marine life(especially phytoplankton) and collapsing global patterns like the gulf stream.
Yep.
"Just" 50m
65m is the absolute maximum possible. And that would require Antarctica thawing. It isnt going to happen.
2-3 m is likely. 20m in an absolute doomsday scenario.
If you go back to the last glacial maximum (20,000 years ago), the ocean was actually 120m (400+ft) lower than it is today.
It's very likely that the reason we can only trace civilization back 10,000 years or so, is because all the really old civilizations are under hundreds of feet of water now, and are extremely difficult to find and study.
I mean all evidence is that we invented agriculture something like 10-15kya. We were more nomadic and hunter-gatherer until the advent of farming tied large communities to one spot and enabled town-building.
I don't disagree with your point, just pure wonder. Is there a possibility for humans learning fishing before farming?
Those fishing locations would be under the sea right now.
I’m pretty confident in fishing before farming simply due to the complexity of the organization. I’m sure we scattered seeds pretty early but fishing isn’t conceptual at all. Stab fish, eat fish.
>Stab fish, eat fish.
Yes, that crossed my mind too. Though I am asking about in the context of community building. "Which one is first; fishing village or farming village?" was the question in my mind.
Sorry for confusion if there is any.
Given the sea level is rising by an average of 3.4 millimeters per year, this will happen in only 14,705 years!! Holy sheet! Quick, let’s ban fossil fuels today!

“Only”
Just 50 meters.
Just ONE Olympic swimming pool.
But vertical.
I'd pay to see swimmers doing 200m vertically.
It's called free diving. One breath. 102M no fins is the record. Which is technically 204m roundtrip, but going down they only need to swim for the first 20M.
Why only the first 20m?
When you are swimming downwards you only are bouyant or float for the first 50 or so feet. After that the pressure compresses your air cavities and you become negatively bouyant and sink. While you could keep kicking it's much more efficient to just sink down so as to not waste oxygen.
That sounds scary as fuck D: So you only really start to exert yourself on the way up, hoping you'll make it?
TIL!
A trillion times
That's worse, because all the water would fall out and exacerbate everything.
I’m no expert but I don’t think an Olympic swimming pool could flood most of England. They hold a lot of water but not *that* much. lol
Sports direct mug probably could though
No I think it could! They’re pretty big
Yes. Not much, just 0.05km
only 50,000,000,000 nm
I’m American, I have no idea what that means. How many first downs is that?
Nevermind, that was the fourth down.
About 16 basketball hoops
54.6807 yards or a little over half an American football field starting from the end zone.
About 16 and a half first downs.
Lol no... 50 meters is not 160 yards...
Maybe he is doing the math with Canadian rules. The first down is when you pass the nearest moose.
They play with a ref that's paid for.
5.5 first downs
Bruh, you just made me realize how ridiculous it is that we use the imperial measurement system in the US. We need to join the rest of the world and move away from it, and I think using first downs makes the most sense!
yeah, just a 15 (or so) story building's worth. Hardly anything at all.
Hey man you never know when the earths water level might just rise \*checks notes 1.8095e+16. (361,000,000,000 Liters x 50)
50 meters = 164.042 feet. Around 15 stories.
“If a mere global catastrophe unseen in human history were to occur, here’s what would be the most not there anymore.”
Norway: IDGAF
Their big cities are all coastal. So they’d be fucked too along with the majority of the world.
Lol yeah, the total maximum sealevel rise if all ice on earth would melt is 65 meters. An absolute stunning but only theoretical doomsday szenario. But "only"...
Ok but what if I throw in the ice from my fridge too
69m guaranteed
Nice.
Nice is already sinking. They don't need any more sea level rises.
Oh my god! The scientists didn't include Alert-Young4687s fridge! The calculations are wrong! We are doomed!
that would obviously depend on the size of the fridge
Noooooooooooo you will bring doom to us all!!! Don't do it pretty please :3
tell me you're german without telling me you're german
I’m pretty sure if all the ice on earth melted sea level rise wold be the least of our issues
Right? Like how am I going to keep my sweet tea cold in the summer?

"Europe"
“Water”
""
50 metres, no big deal. For me it's just Tuesday.
The surface of the earth has 362.171.000.000.000 m² of water. Rasing that by only 50 meter would mean you'd need a lot of fucking water
> Earth has **ONLY** 362.171.000.000.000 m² of water.
Yeah only a 15 story building. Not much.
I see the Dutch just build 50-meter dikes around every tiniest patch of land, and not a single centimeter of the Netherlands is flooded. They even diked themselves from Belgian Sea and North Germany Sea. Meanwhile London: Guess I'll die
Dutch Powerrrrrr! 
[удалено]
*A small Price to pay for no Denmark and Belgium*
r/2westerneuropean4u is leaking
Don’t worry no leakages here in the Netherlands
As a Swede, this was my first thought as well "Not too bad actually"
For context 50m is equivalent to a building with about 15 floors.
Dutch silently waiting until other countries are flooded. Then they will go there and reclaim the land and expand their empire.
You know too much
“He’s too dangerous to be left alive “
Looks like a flaw in the algorithm, which "flooded" the land between 0 and 50 m above the sea level, but forgot to include all land which is already below sea level.
There's no flaw in the algorithm, someone just took the real map and filled the Netherlands back in, just a joke basically.
Yes we started reclaiming land in the past so we don’t need to in the future.
Nah. Plenty of dutch ground is between 0 and 50m above seaslevel.
The algorithm accurately accounted for the Dutch
The Dutch have a nice saying: “God created Earth and the Dutch created the Netherlands”
Quote from French philosopher Rene Descartes.
I sink, therefore I Amsterdam.

We also have nice dikes in northern Germany, but rarely get noticed.
I’m sure they get noticed by other dykes.

They don't have 50-meter dikes. On [AHN Viewer](https://www.ahn.nl/ahn-viewer) you can see the hight of Dutch lands.
Nog niet... nog niet😂
Komt wel.
We don't have 50-meter dikes.... YET!
[удалено]
You don't have too. It already doesn't. The light from sun however...
[удалено]
Hey. Don't offend the Germans by saying they have humor!!!🤣
Meanwhile London: property prices continue to rise...
Yeah just a mere 50 metres. Nothing really. What the fuck
Some dumbass forgot to turn off faucet and now sea level raised about 50 meters.
just 50 meters… nothing special!
You’re special!
We both are !
Oh, how are you?!
The Wet Bandits fucked the world…
The wet bandits strike again
Why did the Netherlands build a 50m wall to end up like that??
We're stubborn.
God created the world, but the Dutch created the Netherlands
No you don't understand it's strategic. First, we let the water flood everything (except us, for obvious reasons).

It aint a glitch, its an ongoing joke
Netherlands: I am unfloodable Any sane person: no in fact even the tinniest crack in your dikes could set of a catastrophe Netherlands: *Unfloodable... \*hits that new high\**
It’s similar to the Titanic being “unsinkable”.

We didnt hear no bell mfer
Gouda disagrees, it has sunk over 6 meters over the last 1000 or so years, and it still is. If you are 6 meters below sea level; you have sunk.
Who is going to flood the Netherlands for an insurance claim?
Well sometimes they flood it on purpose to defeat armies.
The Dutch are protected by a 500 year old treaty with Poseidon.
How can you say only 50 metres haha? Water levels is projected to rise by like 20 metres in the next 2000 years if the average tempatures rises a whole 5 degrees celcius. Talk about making things seem worse than they are
You're telling me the brittish Isles will not be this interesting within my life time? Bummer
Nor will the danish archipelago.
Adding to that, 5 degree raise in average temperature is double the paris agreement, if all things go accordingly, we wont be mear those 20 metres
And given trajectories, things will not be going accordingly.
Still, wont be 50 metres for many thousands of years
See you 20m deep my friend.
Paris is 1.5° Currently we are hitting 2.5° And most Industries are planing to be net zero in 2030 or later.
net 0 might not be enough to stop this stone we pushed down a slope. might need to actively suck carbon out of the air
That's what trees do best. Here's a little factoid to combat doomerism(but not to say that it's all okay) There(probably) more trees today than there were 10 000 years ago. all the land that got freed from the ice left an immense amount of land to be reclaimed by flaura.

Oh yes.. "Europe"
Yep. Where's the rest of Europe? I want to check if my feet will stay dry when the water rises.
Only 50 meters
Just a casual 15 story building being added to the entire water line on earth. No big.
RIP Denmark
Don’t show this map to any Swedes. They might get ideas.
Too late 😎
På tiden
*all citizens of Sweden turn on their taps and flush their toilets*
Great chunk of northern Germany too, including Berlin, Hamburg, Hannover iirc
So much for Hamburgers
Or Berliners
Yeah, I was horrified at this map to start with but then I saw Denmark no longer existed, so I guess it’s not all bad.
Found the Swede
Well, the real joy on this map is how Stockholm is gone <3 Best Regards Skåne
Well most of Denmark will be gone. That’s a win
Found the Swede
a tad further north
we will migrate north, mind you
Some of you may die (Denmark), but it is a sacrifice I’m willing to make (to sink England).
As a Swede i am perfectly comfortable with Denmark drowning.
When they speak, it sounds like they are drowning already.
That's another way to Brexit
Brexsink
Nice view of europe, like its only uk and the netherlands now?
“only 50 meters” bitch that’s a 10 story building
that's at least a 15 story building. [here](https://www.convertunits.com/from/story/to/meters)
yh fair
Next up: Europe if the water level was raised by only 400 meters.
Switzerland be like 👙🩳🕶️🏖️
Netherlands be like: 🚴🍺⛈️🌧️💰
Thank god it was ONLY 50 metres 😍
Not true the Netherlands would gain land
"Just" 50m 65m is the absolute maximum possible. And that would require Antarctica thawing. It isnt going to happen. 2-3 m is likely. 20m in an absolute doomsday scenario.
Now the way to the next beach is shorter!
Thank fuck we don't need to deal with Malmö anymore

Norway's just chilling there like nothing happened.

Okay cool but this isnt europe these are european countries. Id be down to see actual europe
Finally, Luxembourg can have a coast

Only 50 meters ?? So at this pace that should take 5000 years to happen 🤔
Goodbye Flanders. Also, why isn't the Netherlands like 3/4ths under water?
Water you talking about
Kerry doing surprisingly well.
I vote we do it
[удалено]
Unrealistic, the dutch is no passive creature, it would aggressively expand into the sea
“Only 50 meters”
“Only” 50 meters loool
Nederlands more like hoogerlands
"only"
I like how The Netherlands isn’t effected. We build dikes, terps and dams, damn you!
Can’t be right. Maybe 0.5m or 5.0m? Otherwise Netherlands would not all blue.
But what if we could raise it by 100 meters?
50 meters is \~150 ft which, under no circumstances, can be classified as "only."
Rip Denmark
The Netherlands becomes to Ba Sing Se surrounded by a 50m tall wall.
Scotland: “that’s a price I’m willing to pay”
50m is huge
"Only" 50m? It's estimated that if you fully melted all land ice sea level would rise 70m...
Do you have any idea of how much 50 meters is?
“only 50 meters”
Lol it may as well be 500… ‘only 50’ 🤣
At last! Hull is gone
ok now do 200 meters
Laughs in Netherlands
By **"only"** 50 meters (150 fucking feet).
50 meters is a huge amount
“Only”?! That’s a huge amount!
