What Happens if Sea Levels Drop by 1000 Metres? 

mount Everest is now 9878 meters

"Taiwan is now connected to China" Taiwan: Oh hell naw!

"The Falkland Islands are now connected to Argentina" .... me: oh boy... here we go again

"However Australia has bigger problems, it is connected to Indonesia" DAMN

Can you imagine how many wars this would start?

You Forgot to mention that the arctic ocean is now a salty sea/lake

0:25 i like more this version😂

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.

Team Aquas been real quiet since Magma expanded the land....

Jakarta be like : Pheeeww😮‍💨

North sentinel island Connected to Myanmar, that’s fun

Old Zealand

You can literally drive from Sydney to New York if you felt like it for some reason

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 😬

Now it is clearly seen how Malvinas is already part of Argentinian the platform.

Japan: -Welcome to Japan empire Korea: Ah sh it here we go again!

Team Magma be like

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

2:28 Oh dear

Singapore

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.

It’s funny thinking of Denmark and Netherlands- two countries so associated with the sea- to be landlocked.

Italy: gets connected to Tunisia directly by land. Hannibal barca of carthage: Rolls in his grave like a beyblade

🇧🇦: Here we go again!

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.

Would be so cool to take a drive from Canada to Europe. The only big problem would be the lack of bays and capes for fishing

Schrö Lanka 🤣

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

as a canadian, this is quite fascinating

People acting like a thousand meters isn’t a significant drop. Bro there’s mountains which are a thousand meters 😂

Where did thje water go?

Oh no! Argentina borders on the UK!

I think if you can keep a straight face while saying "Doggerland" you have more self-discipline than I do

“The Falklands has connected to Argentina.” The British: 👀…🤨…😡

Florida: Expansion Pack

Would like to see Antarctica

Mauritius here, thanks for highlighting us!

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.

Will give possibility for a long walk...

Just realized the artic ocean is now a huge lake

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.

Tbf, a lot of central land masses will likely become deserts due to being even further from humidity from oceans and lack of water...

No lemuria?

Do you have a link to the map?

British people sweating now that french land forces are at theyre doorstep

I found it interesting that in Indonesia the Wallace Line is suddenly a real feature.

Μεγαλη φαντασια εχεις.

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.

I find it interesting how the "Ring of Fire" coasts barely changed at all while some others changed dramatically.

TFW The Hague - Newcastle is football derby

3:46 caseoh is still bigger than russia

Another problem could be the existing ports would be too shallow or useless, new ones to be built. 👍🇦🇺

A little bit correction is needed. Andaman Nikobar Islands come under India even though they are next to Burma.

The world in an alternative Dutch world conquest timeline.

0:19 Oh yeah. That's the world map I want to have irl.

The missing water would be ice and that means the poles have larger ice caps that would connect more continents.

Someone needs to do a "What-if" scenario and how it would effect the world!

'Have became' its become!!!

Now I want to check out the Australian/France land border.

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.

Would have been nice to overlay the current country sizes (borders) over the projected sizes.

Canada: ...now... 100,000,000,000,000 square kilometers?!

The neck bone is connected to the head bone, etc....

Finally someone with Sea level decrease. I'm sick watching those sea level increases vids . Really appreciate ❤️🇧🇩

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.

The northern hemisphere would be way colder in winter as the gulf steam would travel in a totally different way. England where i pive would be really cold in winter and not the mild damp weather we currently have.

Dude completely ignored the Caribbean

Lets just drink all the water so we can have this

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

R.I.P trade route R.I.P singapore

BRB live streaming me walking from Scotland to uh, Scotland.

1.Sea level decrease 2.Starvation 3.Extincton😢😢

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.

old zealand got back to its glory days

in this unverse, trains rule the planets. ships are for off-shore oil transport but super tankers are far fewer.

Having Indonesia connected to the Philippines is like dream come true for me. I can finally walk there also the British would be triggered knowing Falkland Islands are now connected to Argentina which in case nobody knows, the 2 countries are fighting for it. With that mind, Argentina has more right to own the once an island now it becomes a peninsula.

Where the h*ll is 1000m globally of water going to go? This is as stupid as an 80m level rise!

Wow!

Very interesting indeed.

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.

Why 1000 metres, why not just 100?

Funny how africa is almost completely the same

0:22 ideal world

Argentina would finally have a legitimate claim to the Falklands.

Ukraine is perfectly decreasing without changing the sea level))))))

Wow ❤❤❤❤ ❤from.🇱🇰

As a Canadian, I never realized how deep the Great Lakes are and how shallow is Hudson’s bay! Fascinating stuff

Sunda shelf and Sahul shelf all over again.

What happens if sea levels drop by 1000m? *War*

Next video -->What if sea level is increased by 1000m

Video about what if it rises?

I noticed that the map of where the Mediterranean Sea is at in this. It is very similar to how the map for The Gandalara Cycle looks in the books.

Mongolia and Luxembourg changed a lot

Taiwan - (looks at china)...I'm in Danger. China - (looks at Japan) ...I'm in Danger. Japan - FREE REAL ESTATE!

Falklands connected to Argentina, Saudi Arabia connected to Iran and Chinas evaporated coast line to use it's Navy would be the big conflict points I see from this.

britain doing some colonizing

Laos watching Singapore & Cambodia doesn't have access to the sea: LUL

This Video is victim of the Mercator projection

The UK

Now imagine this is what the world looked like 6000 years ago
