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.

[@mike954]

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.

[@dtvjho]

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.

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.

[@geofflepper3207]

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.

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.

[@MrKanilammit]

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?

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.

[@shofikulislam9091]

could you please tell me from where you got this map?

[@SuzetteKath]

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.

[@johnk-pc2zx]

Great stuff.

[@toastedroast]

Could you do one on possible geological changes these new land masses would have such as climate, quakes or volcanic etc. Hypothetical of course.

I have a feeling the xkcd version of this video would be VERY different.

[@divijdomah6285]

As a Mauritian, this is a W in my book

It would be interesting to see the current shape of each country superimposed upon the new shapes arising from this hypothetical scenario.

[@kristenmccrea5523]

I love your shows.

[@markpijnappels6796]

Interesting to contemplate the growth of existing landmasses such as continents and islands. But what I would have liked to see too is the birth of new islands. Or aren’t there any to speak of?

[@EDunn21]

This kind of shows how deep the ocean gets very quickly in some places (Africa and the west coast of NA for example). Even 1000m of lower sea levels didn’t change the coast at all. I would’ve thought all coasts would change considerably.

[@giftzwerg7345]

i wanna see a video about all the wars that would break out and how they would go

[@faithlesshound5621]

Most of humanity would be long gone, so there would be few people to wage any wars. Polar bears might be able to take over in the North, and penguins in the South.

[@Josh-bq6rm]

If only there was a before and after comparison because I don't remember the exact shapes of most contries

[@man_at_the_end_of_time]

Think of the amount of polar ice cap in size & depth, it would take to do this.

[@salahuddin975]

I didn't realize before that most part of oceans are more than 1KM deep

[@allenmorgan6847]

I would like a video on If Land and Water Traded Places

[@subman721]

5:48 “Mr. Ambassador you nearly 100 naval vessels operating in the North Atlantic right now. Your aircraft has dropped enough sonar buoys, so that a man could walk from Greenland, to Iceland, to Scotland, without getting his feet wet. Now! Shall we dispense with the bull!”

[@ParaballAyCaramba]

6:53 but Greenland is already connected with hans island irl

[@JimmyAgent007]

I'd love a map where the height map was inverted. As in, take the highest point (Mt Everest) and the lowest point, then take the midpoint between the two. Everything above that is now a negative elevation, and everything below is now a positive elevation. Then, drop the same amount of water back on the planet and see what happens. So, not as simple as simply making land water and water into land, but hopefully you get the idea.

[@maggiewong9280]

i think falkland changed the most, it used to be absolutely tiny and then it became a blob

[@iremovedmyhandle]

Netherlands happy sounds

[@snapperl]

The Landwars this would create would be apocalyptic, as nations went to war to get access to the 3 big oceans.

[@andrewharrispiano]

The Maldives has actually grown in land mass. Since 2000, the Maldives have added 37.50 km2 of land area.

[@lordtraxroy]

I would likely say the nothern part of the globe will be un inhabitable because of the ice age and sea level decrease

[@sagittariusa7662]

At least the UK still has a Navy.

[@sgt_s4und3r54]

The thing to consider are all the shelves that would need crossed. Just because the water went away doesn't mean the obstacles did. Any land war across these gaps would be costly and time-consuming.

[@garethmorton5620]

As a New Zealander, NZ isn't actually as unrecognisable as you'd think. Geographically this actually makes it similar to what the islands supposedly would've looked like during the last glacial maxima, according to our school system anyway.

[@elgienbarera4027]

a lot of important ports gone, like Singapore

[@musicaleuphoria8699]

Singapore's in for rude economic awakening.
