7:13 Unintentionally, you've solved the major issue between Greece and Turkey regarding how much of Aegean sea belongs to each country. Thank you so much!
Well, he assigned it all to Greece since all those islands are Greek, so whatever is in between them is Greek land and it emerges from the coasts of each one. Turkey will extend its coast outward only to the midway point where it meets where the coast of every Greek island extends too. And since practically all the Greek islands are right in front of the Turkish coast, Turkey hardly grows anything into the Aegean sea.
I'm so close yet so far... I live 800m above sea level, my country as a whole is very low, I'm in one of the regions with the highest overall height, tho my city is a bit lower because we are close to sea, I live 50km from the closest beach
This is hard to explain in english, but as a chilean, we have a terrible "problemo": Our coast is 6430 km lenght (4000 miles), and right in front of all of our coast, from north to south, it is located the Peru-Chile Trench, that delineates the boundary between the Nazca Plate and the South American Plate. This trench is the responsible for all the earthquakes that we have in Chile, and is very deep (at 8000 meters under the water, 4.9 miles), and located only at 160km or 100 miles from the coast, under the water. So, if the sea level drops by 1000 meters, all of our coast cities will be located in front of an unbelievable huge fall, very inclined, similar to a cliff. It's like if those cities where built in the middle of a very high mountain. The water will be very far away, and it will be very hard to find some land to build in those places.
hmm you know that a drop of 8000 metres over a distance of 160 km is actually nothing like a cliff at all? It's a ratio of 1 in 20 which is a really gentle slope. I know it's not uniform and there would be steeper bits but those would tend to be near the bottom of the trench, not in the first 1000 metres.

What will China do now with the strait of Malacca completely closed? Import oil from Russia? What will Russia do with literally 0 coastline connecting the Atlantic? Gulf countries will either succumb to Saudi Arabia or Iran or destroy each other. Another question is since all land is now connected, can we call this a supercontinent? If yes, then given that the land massss are already connected under the ocean, does a supercontinent already exist?
The Chinese Government before the Communist Government took Taiwan over as the Chinese Government in Exile, so yup, they would be freaking at a land connection forming.
💀 They have truly rejoined the motherland, literally.Plus, being Singaporean, we would suddenly become landlocked and our ports will become useless and our economy will fall severely lol “0v0
4:08 in order for the sea level to drop, we would be in another ice age. So Russia wouldn't be able to drill for oil, because all that area would be covered with ICE.
In this map, the lake in between the borders between Canada and Greenland would become the deepest and largest lake on Earth. It would get up to 7000 ft deep. Also, many shores would now be way difference, since instead of you being able to walk around the shore and it only gradually getting deep, it would instantly drop thousands of feet
It looks like he just dropped the water level just past the continental slope. Sure, it'd give us more land, but it'd wreck havoc on the environment and ocean currents. Not to mention oceanic trade would be severely impacted. And where'd all that water go?! Did it evaporate? If so then that would drop lake water levels as well. If it got locked up in ice all that land mass in Canada and Russia would be covered in glaciers and would add to the water level of the upper Northern Hemisphere lakes like the Great Lakes, the Hudson Bay, and Caspian Sea (depending on the southern extent of the ice sheet). That gradual deepening of the water you talked about is also where a lot of marine organisms live. And the continental slope is where a lot of sedimentation occurs and upwelling of nutrients in the winter months happen, 1000m (~3281ft) below sea level.
Yes, the new sea level, being below the edges of the continental shelves worldwide, means the end of flat beaches in most areas, the level is part way down the cliffs that already exist, but the lower 80% of the cliffs would remain submerged. An effect on sea trade would be the elimination of large flats and shallows, and the need for constant dredging. Large ships could berth directly at the cliffs with new terminals. But most saltwater marshes would disappear.
Netherlands would already be landlocked if sea levels would only decrease by 50-100m and the baltic sea would already be a lake by then. Denmark/Sweden would only have a very small strip of ocean access near Skagerrak, not even reaching to the Gothenburg area.

I'm wondering what driving through the mountains of Greenland would be like, especially as the low sea levels imply an ice age with a huge ice sheet across North America and a much bigger ice sheet in Greenland as compared to the ice sheet there today.
Most of this new land would end up as scorching dry desert or freezing cold wastelands. Also the regions furthest from the sea would have even greater seasonal variations than they already have.
The Med in this video has become an inland sea/lake and would eventually evaporate. The Sahara would move north and most of southern europe would become desert. This was modeled previously when those insane plans from the early 20th century came up that suggested that they close the Suez canal and dam the Med at Gibraltar.
@@jshsvsjejed6960 Yes. But overall I reckon most land would be useless. Think of a Sahara connecting with both Europe (the Meditarrenean sea now turning into a slowly evaporating lake), the Red Sea (also a now a slowly evaporating lake) and the whole desert region jutting into Iran. The likes of the Maldives and the Azores gaining a bit of land would be nothing compared to the absolute tragedy for the rest of the world.
I have seen that sea levels were only around 120m lower during the last ice age and that resulted in around 1/3 the landmass being glacier. We are looking at around 8x lower sea level here, so that much more water going into glaciers. Would we see the supposedly former "green Sahara" become icy?
Baltic Sea disappeared. So Russia has access to the oceans only from the underdeveloped eastern coast. I am guessing Black sea also becomes a lake which is another access point. So Suez Canal unless somebody digs a longer one. I wonder if Panama also became too fat to make a canal prohibitively expensive. People don’t need a boat to escape from Cuba to Florida. Similarly Europe will be more accessible for African immigrants. Greece and Turkey become really close neighbors 😬
I was going to say that they could dredge the Panama canal and maybe the Suez, but then I realized that your locks would have to raise the ships an additional 1000 m which would seem to make both canals unusable for that reason alone.
A few things: 1 - Some parts of seas would become cut off from the oceans and with no outlets which means that eventually they might become very salty and have higher concentrations of contaminants. 2 - This would cause huge problems for marine life used to today's geography as migratory species would in some cases be cut off by land barriers and obviously a lot of shorelines would move significant distances. 3 - For this to occur the water has to go somewhere and that presumably would be into massive ice sheets covering much of North America, Europe and Asia. Those incredibly heavy ice sheets tend to push down the middle of continents while in places the coastlines just outside the ice sheets might rise the same way that when you sit on a mattress the part you sit on goes down while the mattress around you actually rises up. Apparently in North America the middle of the continent is still slowly rising recovering from being pushed down in the last ice age while some areas around the coasts such as Washington DC which rose during the last ice age are still today sinking in recovery - that's a problem in an era when due to climate change sea levels are rising and heavier storms upriver could mean higher storm surges in the river flowing through Washington. 4 - Such a change in ocean levels would almost certainly play havoc with ocean currents such as the gulf stream which currently keeps Europe far warmer than its latitude would imply ..... though that may not matter much as the much lower sea levels indicates that Europe would already be covered by an ice sheet as the most likely place for all that sea water to go is into ice sheets. 5 - If sea levels are 1,000 metres lower in a sense that means that every place on land is effectively 1,000 metres higher altitude above sea level. If that means that atmospheric pressure becomes lower at every place on land on Earth does that mean that people start finding themselves more out of breath where they live and does that mean that it becomes impossible for anyone to climb to the top of Mount Everest or K2 and survive? Could even a modern mountain climber with full modern equipment have climbed those mountains during the last ice age when sea levels were much lower? 6 - Surely this will play havoc with weather patterns and river flows. 7 - If this magically happened overnight it would really mess up business for ports, costal tourist resorts, fishing communities, etc that would find themselves far from water with all their water related infrastructure far up above sea levels. A lot of ships would suddenly be stranded, aground far from the sea. In terms of sudden changes like that the 1968 Canadian film The Rise and Fall of the Great Lakes with canoeist Bill Mason is amusing, somewhat informative and available online.
3 - North America is still rebounding from the last ice age, so presumably its subsidence would take just as long. 4 - The changes would be catastrophic. 5 - The ice sheets would be thousands of meters deep, displacing the air. This means the air pressure at current sea level would be about the same. At the new sea level it would be higher than it is currently. 6 - Less water evaporating in the tropics would mean continental interiors would be drier than they are now with more extreme annual temperature extremes.
One of the problems with simulations is with interior seas currently connected to world sea level. Programs frequently fail to take into account the depth of the straits that tie them to the ocean. Once sea level falls below the bottom of the strait, that connection dries up, and the interior sea levels off (and becomes a fresh water lake). For the Black Sea to be cut off, world sea level needs to drop 110m. The Strait of Gibraltar is 950m deep, so at 1000m the Mediterranean would be cut off.
Would it become fresh water lake? Where would the salt water left in the new lake go? Also, wouldn't salinity levels, in those lakes and the oceans, increase?
3:32 well… except for the fact that since so much water has been removed, the atmosphere would contract inward making those places higher up into places where you can barely breathe. Basically, Mt Everest but everywhere along the Himalayas
Sea levels were supposedly only 120m lower during last ice age when Canada was pretty much under a glacier. Now we are talking around 7-8x lower sea levels and that much more water going to glacial formation?
The most fascinating thing is that these super unknown, super southern islands like the Sandwich or whatever islands, would now become inhabitable and there would probably be a significant amount of settlements with lucrative mining and fishing opportunities. It would be really cool to have an Antarctic subpolar region like we do in the north - not as cold as the full-blown polar but still pretty cold, yet inhabitable.
For sea level to drop 1,000 meters, we'd need to have an ice age much more extreme than the last few. This means those islands would all be iced over. Alas.
As a non native English speaker I find it fascinating to observe changes that are taking place in the language. One such change is the conjugation of irregular verbs. I notice that the past perfect tense becomes like the past tense. Like when as in this video the narrator consistently say "has became". As far as I can tell there are few verbs for which that is not the case. The verb "to be". I never once heard anyone say "has was". I distinctly hear the narrator still consider "to grow" to be irregular. He still uses the old "has grown" and not "has grew". Interesting.
06:50 Well, as a Faroese, I would definitely also claim those two large islands to the SW of us, which are in this map coloured with the UK colours. It's only fair. ;) 07:20 Oh, there is a serious error here. It looks like whoever made this map completely forgot about Jan Mayen which is a Norwegian and not a Greenlandic island. So most of those islands E of Greenland and N of Iceland would be Norwegian.
It's strange that the world map with the lowered sea level resembles some early historical maps. As if historically the sea level had indeed dropped and the cartographer's sources had recorded it a long time ago.
Does this map also take into account the isostatic adjustment & crustal displacement that may occur? It is likely due to the increased weight of the polar ice caps and causing the distension at the equator and thin ocean crusts. Hence, is it possible other landmasses, [e.g. Mid-Atlantic Ridge and/or larger Zealandia or Hawaii] might rise above the lower sea level? To date, I haven't seen any glacial maximum maps take this into account. Just asking.
The Andaman and Nicobar islands are owned by India, but this map shows them now as part of Myanmar. I think the most devastating part of this map is all those famous beaches of Thailand are mostly gone. Argentina would have a much stronger claim to the Malvinas.
I can imagine New York in this world being similar to how it was in the movie "The Fifth Element" where the Hudson and East Rivers are completely gone and Manhattan becoming a mountain.
I've lived near the ocean my entire life and the water level has never changed. The beach is still there and the water has not eroded the small sea wall that's there.
Obama bought a $11+ million estate house on Martha's Vinyard. Nobody fearing salt water intrusion is going to spend that kind of money on an oceanfront house.
Cool! It would be interesting to see what landmasses there were during the ice age. What landmasses has been lost since then? According to studies the sea level were approximately 130 m lower than today.
Interesting video. What happened to the roughly 260 million km^3 of water? It had to go somewhere and would likely sit on top of all that new land in Russia, Norway, and Canada.
What? No... 2,000 years ago? It was Romans period, the world looked like now. Maybe 2 million years ago it might have been more like this, but there weren't civilizations around to build the things you said. Where did you get that from?
@@RickZanardi In the Western side of India near the coast line of Gujarat the Archaeological Survey of India had found remains of an ancient city under the sea. And recently researchers from Deccan College Pune along with the Archaeological Survey of India have established that human remains discovered at an ancient site of Rakhigarhi in Haryana date back around 8,000 years. So I think we can find more remains of different ancient civilizations
@@RickZanardi I don't think they meant "couple" as literally two. I assume "couple" as in during the last ice age. But even still, sea levels were supposedly only around 120m lower during the last ice age.
@@tezsinha6405 I have no doubt that near today's coastline there are plenty of submerged villages and towns that some day we will discover, the coastline evolves even you don't account for sea level and 8 thousand years is enough for the shoreline to evolve. But the comment above suggests that there are submerged cities on the coastline that you see in the video, so close to 1,000 m underwater, from a couple of thousand years ago. Let's double that, let's go 4-5 thousand. Ancient Egypt time: if the world looked like this the Nile delta would have been in the middle of today's Mediterranean. This is out of any stretch of possibility within the civilization timeframe.
@@MrKanilammit exactly, I fully agree. And the ice age did not fulfill many criteria for which today we can suppose great cities and civilizations were there. It's cavemen period, maybe some advanced groups had huts or rudimental housing, but that's all...
You didn't show the massive ice sheet covering a big part of the northern hemisphere. The one that covered half of North America 20000 years ago contained enough water to lower sea level by more than 120 metres. A 1000 metre drop would in sea level would create enough ice to glaciate most of the world's land
To be honest, what is incredible is how little the world changes with a 1000 metre sea level drop. Really shows just how deep the oceans are and how much effect they have on the planet.
I liked the information given by you very much. Please make a detailed video on Qattara Depression also. And also on a video for Andaman and Nicobar Islands. 😊😊😊

2:11 Indonesia will greatly benefit because the islands are connected to each other, making it easier to distribute development evenly. Indonesia will also control important trade routes through the Timor Sea and several narrow seas around the East Nusa Tenggara islands (and apparently Australia won't like that) and than the military will increase security on the borders of Papua (Indonesia), PNG and Australia. Maybe there will be a little tension there.

People used to walk between Alaska and Russia insofar as the two Diomedes islands are connected by frozen sea for much of the year. Nowadays the locals who still live on the Alaskan (little Diomede) are not allowed to walk to the Russian (Big Diomede), and Big Diomede does not allow civilian settlement anymore. Good video, interesting and well presented.

Europe and Asia.
Those incredibly heavy ice sheets tend to push down the middle of continents
while in places the coastlines just outside the ice sheets might rise
the same way that when you sit on a mattress the part you sit on goes down
while the mattress around you actually rises up.
Apparently in North America the middle of the continent is still slowly
rising recovering from being pushed down in the last ice age
while some areas around the coasts such as Washington DC
which rose during the last ice age are still today sinking in recovery -
that's a problem in an era when due to climate change
sea levels are rising and heavier storms upriver could mean
higher storm surges in the river flowing through Washington.
4 - Such a change in ocean levels would almost certainly play havoc
with ocean currents such as the gulf stream which currently
keeps Europe far warmer than its latitude would imply .....
though that may not matter much as the much lower sea levels
indicates that Europe would already be covered by an ice sheet
as the most likely place for all that sea water to go is into ice sheets.
5 - If sea levels are 1,000 metres lower in a sense that means that every
place on land is effectively 1,000 metres higher altitude above sea level.
If that means that atmospheric pressure becomes lower at
every place on land on Earth does that mean that people
start finding themselves more out of breath where they live
and does that mean that it becomes impossible for anyone
to climb to the top of Mount Everest or K2 and survive?
Could even a modern mountain climber with full modern equipment
have climbed those mountains during the last ice age when
sea levels were much lower?
6 - Surely this will play havoc with weather patterns and river flows.
7 - If this magically happened overnight it would really mess up
business for ports, costal tourist resorts, fishing communities, etc
that would find themselves far from water with all their
water related infrastructure far up above sea levels.
A lot of ships would suddenly be stranded, aground far from the sea.
In terms of sudden changes like that the 1968 Canadian film
The Rise and Fall of the Great Lakes with canoeist Bill Mason
is amusing, somewhat informative and available online.
name of that movie?
u forgot to mention effects on weather pattern
3 - North America is still rebounding from the last ice age, so presumably its subsidence would take just as long.
4 - The changes would be catastrophic.
5 - The ice sheets would be thousands of meters deep, displacing the air. This means the air pressure at current sea level would be about the same. At the new sea level it would be higher than it is currently.
6 - Less water evaporating in the tropics would mean continental interiors would be drier than they are now with more extreme annual temperature extremes.
Would tide changes be more drastic?
One of the problems with simulations is with interior seas currently connected to world sea level. Programs frequently fail to take into account the depth of the straits that tie them to the ocean. Once sea level falls below the bottom of the strait, that connection dries up, and the interior sea levels off (and becomes a fresh water lake). For the Black Sea to be cut off, world sea level needs to drop 110m. The Strait of Gibraltar is 950m deep, so at 1000m the Mediterranean would be cut off.
Would it become fresh water lake? Where would the salt water left in the new lake go? Also, wouldn't salinity levels, in those lakes and the oceans, increase?
@@MrKanilammit Runoff from heavy rains would cause water to exit via the cutoff strait, like a river, taking salt with it.
I find it interesting how the "Ring of Fire" coasts barely changed at all while some others changed dramatically.
3:32 well… except for the fact that since so much water has been removed, the atmosphere would contract inward making those places higher up into places where you can barely breathe. Basically, Mt Everest but everywhere along the Himalayas
The biggest issue would become the glaciers that would cover much of the Northern hemisphere
zealandia would be so much bigger than you've shown so would be the most unrecognisable for sure
Yeah but you would have to drop sea levels like 3km
Zealand is a much larger landmass, sea-level need to drop few more 100 metres to fully expose it's true size
as a canadian, this is quite fascinating
As a Canadian, I enjoy looking for New Zealand on maps (there are a few maps that forget to include it)
Right! And it looks like kids won’t have to struggle to colour in Nunavut anymore 😂
Sea levels were supposedly only 120m lower during last ice age when Canada was pretty much under a glacier. Now we are talking around 7-8x lower sea levels and that much more water going to glacial formation?
@@MrKanilammit I found a layer of seashells in a gravel pit some 300 feet above sea level. There’s been a lot of change over time.
Don't get any ideas😆
The most fascinating thing is that these super unknown, super southern islands like the Sandwich or whatever islands, would now become inhabitable and there would probably be a significant amount of settlements with lucrative mining and fishing opportunities. It would be really cool to have an Antarctic subpolar region like we do in the north - not as cold as the full-blown polar but still pretty cold, yet inhabitable.
For sea level to drop 1,000 meters, we'd need to have an ice age much more extreme than the last few. This means those islands would all be iced over. Alas.
@@mysteriousDSF I think you meant to say habitable
@chadhenry961 inhabitable is the same. Uninhabitable is when you can't live on it
@@mysteriousDSF ok I misread it
As a non native English speaker I find it fascinating to observe changes that are taking place in the language.
One such change is the conjugation of irregular verbs.
I notice that the past perfect tense becomes like the past tense. Like when as in this video the narrator consistently say "has became".
As far as I can tell there are few verbs for which that is not the case. The verb "to be". I never once heard anyone say "has was".
I distinctly hear the narrator still consider "to grow" to be irregular. He still uses the old "has grown" and not "has grew".
Interesting.
As a native English speaker "has became" and "has grew" sound strange to me. I would always use "has become" and "has grown".
"Has became" is not correct English. It's "became" or "has become".
Good video thanks - can you also include Hawaii the next time you make one of these. Would like to see if all the islands would one day?
Tbf, a lot of central land masses will likely become deserts due to being even further from humidity from oceans and lack of water...
“The Falklands has connected to Argentina.”
The British: 👀…🤨…😡
Don’t worry we’d just reclaim the Republic of Ireland instead as they would be obscuring our access to the Atlantic Ocean.
Don’t worry we’d just re-annex the Republic of Ireland instead, as they would be blocking our access to the Atlantic from the west.
Indeed they are already inside Argentinian platform, they always belonged to us.
If sea levels drop 1000m you can have them. World War 3 will have broken out in a global land grab, we'll be too busy at home.

Team Magma be like
Anyone notice at 8:02 the lakes from the US towards Canada are sort of in a diagonal line ?
@@ndirangugichuki6260 yep they are like that in real life. One of them is called great slave lake
Australia: Oi, Indonesia! I’m annexing you, mate.
Indonesia: Uno Reverse.
The missing water would be ice and that means the poles have larger ice caps that would connect more continents.
06:50 Well, as a Faroese, I would definitely also claim those two large islands to the SW of us, which are in this map coloured with the UK colours. It's only fair. ;)
07:20 Oh, there is a serious error here. It looks like whoever made this map completely forgot about Jan Mayen which is a Norwegian and not a Greenlandic island. So most of those islands E of Greenland and N of Iceland would be Norwegian.
Finally someone with Sea level decrease.
I'm sick watching those sea level increases vids .
Really appreciate ❤️🇧🇩
What's so repulsive about if sea levels rised but if they decreased is okay?
Are you overreacting?
Thats whats happen if there is an another ice age but in a massive way with if sea level will drop
@@ta_w_si_f me too, we’ve got plenty of theories about sea levels rising, & not many dropping.
But what about Antarctica and the Hawaiian islands?
2:39 Taiwan: “ohh shit…”
Jakarta be like : Pheeeww😮💨
I found it interesting that in Indonesia the Wallace Line is suddenly a real feature.
Would have been nice to overlay the current country sizes (borders) over the projected sizes.
It's strange that the world map with the lowered sea level resembles some early historical maps. As if historically the sea level had indeed dropped and the cartographer's sources had recorded it a long time ago.
Does this map also take into account the isostatic adjustment & crustal displacement that may occur?
It is likely due to the increased weight of the polar ice caps and causing the distension at the equator and thin ocean crusts.
Hence, is it possible other landmasses, [e.g. Mid-Atlantic Ridge and/or larger Zealandia or Hawaii] might rise above the lower sea level?
To date, I haven't seen any glacial maximum maps take this into account. Just asking.
The Andaman and Nicobar islands are owned by India, but this map shows them now as part of Myanmar. I think the most devastating part of this map is all those famous beaches of Thailand are mostly gone. Argentina would have a much stronger claim to the Malvinas.
"owned" no. You should instead write "part of" or "administered"
@@islandsunset Semantics.
how would the sentinelese react
I can imagine New York in this world being similar to how it was in the movie "The Fifth Element" where the Hudson and East Rivers are completely gone and Manhattan becoming a mountain.
It would be cool to see this in a globe format. The arctic has changed drastically but it’s difficult to visualize on a flat map.
I've lived near the ocean my entire life and the water level has never changed. The beach is still there and the water has not eroded the small sea wall that's there.
Obama bought a $11+ million estate house on Martha's Vinyard. Nobody fearing salt water intrusion is going to spend that kind of money on an oceanfront house.
Cool! It would be interesting to see what landmasses there were during the ice age. What landmasses has been lost since then? According to studies the sea level were approximately 130 m lower than today.
Chile is that kid who can't get fat no matter how much he eats
🤣
Mauritius here, thanks for highlighting us!
dawg you from mauritius? never actually met anybody from any of the little island nations wow
A little bit correction is needed. Andaman Nikobar Islands come under India even though they are next to Burma.
India, Indonesia and Myanmar gonna fight for it.
It's horrifying to think that Tasmanians could become Mainlanders.
Hi, nice video. What about Antartica?
Another problem could be the existing ports would be too shallow or useless, new ones to be built. 👍🇦🇺
All current ports would be 3,000 feet above sea level, so yeah... all new ports.
Peru-Chile coast would be a huge cliff.
Nazca rift subduction zone
Interesting video. What happened to the roughly 260 million km^3 of water? It had to go somewhere and would likely sit on top of all that new land in Russia, Norway, and Canada.
i drank it all
@@siyacer well, you would still have to pee it all out though, so it still has to go somewhere...
Ice.
@@1Albedospace piss
This scenario could only happen from an extreme ice age, so the water would be bound up in enormous ice sheets covering both poles.
This is what the map looked like a couple thousand years ago, you will find many ancient structures and cities on the coastal regions of this map.
What? No... 2,000 years ago? It was Romans period, the world looked like now.
Maybe 2 million years ago it might have been more like this, but there weren't civilizations around to build the things you said. Where did you get that from?
@@RickZanardi In the Western side of India near the coast line of Gujarat the Archaeological Survey of India had found remains of an ancient city under the sea. And recently researchers from Deccan College Pune along with the Archaeological Survey of India have established that human remains discovered at an ancient site of Rakhigarhi in Haryana date back around 8,000 years. So I think we can find more remains of different ancient civilizations
@@RickZanardi I don't think they meant "couple" as literally two. I assume "couple" as in during the last ice age. But even still, sea levels were supposedly only around 120m lower during the last ice age.
@@tezsinha6405 I have no doubt that near today's coastline there are plenty of submerged villages and towns that some day we will discover, the coastline evolves even you don't account for sea level and 8 thousand years is enough for the shoreline to evolve. But the comment above suggests that there are submerged cities on the coastline that you see in the video, so close to 1,000 m underwater, from a couple of thousand years ago. Let's double that, let's go 4-5 thousand. Ancient Egypt time: if the world looked like this the Nile delta would have been in the middle of today's Mediterranean. This is out of any stretch of possibility within the civilization timeframe.
@@MrKanilammit exactly, I fully agree. And the ice age did not fulfill many criteria for which today we can suppose great cities and civilizations were there. It's cavemen period, maybe some advanced groups had huts or rudimental housing, but that's all...
Fantastic job with the geography content! Your videos are both cool and educational. 🌐👍
This is so interesting. Thanks for the content 🙏🏽
You didn't show the massive ice sheet covering a big part of the northern hemisphere. The one that covered half of North America 20000 years ago contained enough water to lower sea level by more than 120 metres. A 1000 metre drop would in sea level would create enough ice to glaciate most of the world's land
The video is only about if ocean levels were lower than they are now, he doesn't need to provide a reason. It's purely speculation on one criterion.
We didn't freeze the water, we took it to terraform Mars.
Someone needs to do a "What-if" scenario and how it would effect the world!
agreed
My immediate thought is what happens to the amount of fresh water and the geopolitics behind that change
Lets just drink all the water so we can have this
😐
“I personally think new zealand changed the most”
Denmark: Bruh
Please do 2,000meters next 😊
As a Brit I would hate to have a border with the French
To be honest, what is incredible is how little the world changes with a 1000 metre sea level drop. Really shows just how deep the oceans are and how much effect they have on the planet.
It also shows how BIG the oceans are: 70% of the Earth's surface x 1000m. Where did it all go???
I think the reason why Africa barely changes is not that it is not affected, it due to lack of accessible data on this topic.
Can you post higher Res versions of your maps?
I liked the information given by you very much.
Please make a detailed video on Qattara Depression also. And also on a video for Andaman and Nicobar Islands. 😊😊😊
1.Sea level decrease
2.Starvation
3.Extincton😢😢
How does this work, it makes zero sense
And the faster it happens, the worse the extinctions.
Netherlands happy sounds
British people sweating now that french land forces are at theyre doorstep
Why is that, are they surrendering
Antarctica be like: I guess this doesn't concern me. 😢
@TheGeographyBible What simulator did you use to view the world at -1000 meters. I would like to see what the world would look like at greater sea level drops.
Why 1000 metres, why not just 100?
No clicks for 100.
Where the h*ll is 1000m globally of water going to go? This is as stupid as an 80m level rise!
Ukraine is perfectly decreasing without changing the sea level))))))
I wish you had added a transparent overlay of how the map looks currently over the new lowered sea level map.
7:17 What's that new land SW of the Faroe Islands and NW of Ireland?
2:11 Indonesia will greatly benefit because the islands are connected to each other, making it easier to distribute development evenly. Indonesia will also control important trade routes through the Timor Sea and several narrow seas around the East Nusa Tenggara islands (and apparently Australia won't like that) and than the military will increase security on the borders of Papua (Indonesia), PNG and Australia. Maybe there will be a little tension there.
I want to see what the pacific islands were like 40,000 years ago when the sea level was 250 feet lower. What program can I use to see this?
I wish you could do a part two exploring the change in Earth’s climate if this happened.
6:53 but Greenland is already connected with hans island irl
Why does this feel satisfying but indescribable at the same time
A really fun video idea, thank you
When will this happen ? Been thinking about retiring to Florida.
couldnt get my head round Singapore going from a tiny island city-state to just being a city 4 or 500 miles inland . they'd have to give up the drydocks , the oil refining and the merlion logo etc
It’s not in NK. When I went to high school in the US, it was also in the middle with Asia cut in half.
I wanna rule out new land invasion routes. With sea level dropped, the places that used to be beaches could now be cliffs hundreds of meters tall
Like your Channel man. Have always been a man who loves Geography, just never knew what to do further in it.
People used to walk between Alaska and Russia insofar as the two Diomedes islands are connected by frozen sea for much of the year. Nowadays the locals who still live on the Alaskan (little Diomede) are not allowed to walk to the Russian (Big Diomede), and Big Diomede does not allow civilian settlement anymore. Good video, interesting and well presented. Consider the Caspian Sea which, although a lake, would probably lose at least one third and perhaps even two thirds, resulting in a number a countries there being joined by land.
What’s the music you used for this?
That's one freaky RISK map! 😳
