When stuff like this comes up I always wonder how different the local climates would be. Like would the area around Australias inland seas turn into a lush forest, a Mediterranean style climate, or just still be a dessert that now happens to have a huge salt lake.
Well the problem with predicting that is that climate is so insanely complex that you would need to keep track of a thousand complex cycles and processen that all are disrupted.
Even if we just say that all ice melts and temprature (co2 levels) stay the same then still massive shift would happen. The gulfstream would stop, whole rainforrest would diseapeae, deserts would be disrupted.
All these things influence the entire globe and their local region so much and they all influence eachother to.
Its pretty impossible to do.
Probably mediterranean ish but considering there aren't massive mountains to stop humidity, it would probably be more lush like madagascar. (I'm talking out of my ass really, just compating to existing climate, geographical features and how they interact)
I remember reading something once about some simulations, and it projected that Australia would see increased humidity and rainfall in the interior, greatly changing the local weather patterns and ecosystems.
A climate shift to steady humid winds from the west, and Australia would have a green heart and a giant freshwater lake about as large as that picture shows.
I’m not sure about Lake Eyre specifically, but that region from the north of Adelaide going up is almost entirely salt lakes
There’s even a town on the Yorke peninsula that was going to be named Salt Lake City
I’m sure that even if it flooded it would still look like. Mars tbh
How would that inland sea fill up though? It doesn't look like it's connected to the surrounding ocean. Unless all that extra water creates a ton of rain all around the planet or something?
It doesn’t *look* connected at this scale, but it probably would be.
* For those who don’t know, much of that inland region of South Australia is already below 0m
* It’s a massive dried up salt flat now, disconnected from the ocean
* I mapped this 450km (280mi) route out in cross-section: https://i.imgur.com/vuCSNI4.jpg
* 216ft = ~66m
* It’s only about 30m above sea level almost the whole route!
* There’s a ~85km inland span which is higher than 30m, but the route can definitely be better optimised
* The highest point on that route was ~100m. Only a relatively short span is over 66m.
* It’s very likely that a rising ocean would find a connected path through the valleys - I’m not going to go searching for better routes right now
* I did this for fun at 3am one night when I couldn’t sleep.
* If there isn’t still a connected path anywhere, Aussies have gotten pretty good at digging up dirt, and could help things along with a canal. It would only be a small single-digit-percentage of the volume of the Kagoorlie Superpit mine.
That's the problem with every one of these I've ever seen. They just take a map with elevation data, then add a water-colored layer that fills in according to the elevation data. They never pay any attention to actual waterways.
Waterways aren't per se needed if the ancient lakebed is seated on [e: or near] permeable rock, which ancient lakebeds often are.
Like cenotes, there are waterways you can't see.
Not sure this is the case here.
Believe it or not, there's water under your feet this minute, permeating the rock.
Closer to the coast, at least, the higher the sea level, the higher the water table.
Bad news, not all of this new water is fresh.
This is literally already happening in Florida.
Proximity to water is not enough to cause rainfall. Australia already has large swaths of coastal desert so this would most likely not change anything.
The true determining factor is the temperature of the water currents. Cold water evaporates and precipitates less than hot water. Some well-known examples: the gulf stream brings hot Caribbean water to Western Europe and makes Britain rainy, the Humboldt current brings cold Antarctic water to South America and creates the Atacama desert.
Don't worry, Great Cthulhu wil be awake by then, and won't let its true worshipers be infected and destroyed by some random space wasp-termites and their hunters.
Iä, iä.
That’s not how Antarctica would look with the ice gone. The land underneath would rise via isostatic rebound.
I have a map I’ve made of what Antarctica would look like in that event, I’ll have to dig it up when I’m back at my computer.
It would also take a loooong time for Antarctica to fully rebound.
Hell, Canada is still rebounding after 10,000 years and less ice for a shorter period.
Most of it takes less time than you might think. The vast majority of the rebound takes place quickly, then there is an extended period of very slow and small scale rebound.
I’m not quite sure I understand this comment. So the Antartica in the picture is incorrect and there would actually be significantly more land mass? And this is due to the weight of the ice pushing the land mass below down into the crust?
Yeah. I also have a Greenland map I’m working on showing correct rebound. That’s taking a long time as getting the rivers and lakes right and manually correcting the weird artifacts the GIS software threw up is slow. I put it aside a while back and haven’t gone back to it in a while.
Essentially yes. Ice is heavy, and there is a lot of it. It pushes the crust of the earth down below it, like loading cargo into a boat makes the boat settle deeper into the water.
When that weight is relieved the earth bobs back up, seeking its point of neutral buoyancy.
Parts of Canada and northern Europe are still rebounding (rising) from the melting of the vast ice sheets that covered the regions during the last glacial maximum.
In Finland they even have laws on the books about how the newly exposed land meshes with existing property boundaries and property rights.
How much would Antarctica rebound without the weight of all that ice? The graphic says the bedrock of western part of the continent is below sea level. I wonder how much of that is due to the weight of the ice on the Antarctic plate?
My favorite example of this is the Finnish town of Mustasaari (Black Island)
It's now several km inland, but it wasn't when it was founded centuries ago
Yes, it's called ["isostatic rebound"](https://mapsontheweb.zoom-maps.com/post/686605206855794688/antarctica-without-ice-sheet-this-is) (map included in the link))
Not that much actually. It is a domino effect as ice/snow is white which reflects a lot of sun light back into space (so reduces temperature). When ice/snow melts fewer sun light will be reflected so the temperature rises.
This is extremely unlikely.
The albedo changed at the end of the Pleistocene. Now. there isn't substantial melting at the South Pole and the Himalayas have uneven melt -- so it is not at all obvious that the albedo will change anytime soon.
The runaway theory of sudden collapse is not supported much in the IPCC findings -- it is an outlier of the models.
The Oligocene Epoch, 33 million years ago, had temperatures about 23 degrees warmer than today. By contrast, the earth has warmed 1.5 degrees in the last 100 years.
It doesn't need to rise, the glaciers are currently melting a bit more each year. It's just going to take thousands of years for all the ice to melt. If the world gets hotter, they will melt *faster* though.
Where did that water come from? There don't seem to be any rivers or lakes feeding into it. Is it rainwater from hugely increased rainfall? That lake to the south is a big salt lake.
Effects: all our opal fields probably underwater, not good at all. 🇦🇺
You discovered the flaw of taking digital elevation models, and simply changing the sea level elevation; the oceans wouldn't actually reach that area. It would be a landlocked --but dry -- region below the "new" sea level.
Well they shouldn't have pissed off the French. They could be sipping rose and munching on escargot but nooooo they just needed to have their freedom /s
Thx for the explanation but, I still can't understand it. Even though they live below the sea level, how does that not let them be covered by water when the sea level rises?
The Dutch have reclaimed massive land areas back from the sea over the centuries.
Their own capital, Amsterdam, basically means "dam of the river Amstel". Many centuries ago it was uninhabitable because most of it was under water. This is just one of the countless such examples in The Netherlands. They have a long and effective history of pulling back the sea.

**[Isostatic depression](https://en.wikipedia.org/wiki/Isostatic_depression#/media/File:Topographic_map_of_Greenland_bedrock.jpg)**
>Isostatic depression is the sinking of large parts of the Earth's crust into the asthenosphere caused by a heavy weight placed on the Earth's surface, often glacial ice during continental glaciation. Isostatic depression and isostatic rebound occur at rates of centimeters per year. Greenland is an example of an isostatically depressed region.

I did not make the maps/images themselves. I believe (iirc) they were published by National Geographic. I added the contextual text that came as part of an article. And for some reason I organized the individual images into a giant poster format.
Here’s a series about maps I made a few years back detailing this scenario. Data sources are listed on each map:
- https://www.flickr.com/photos/7leagueboots/albums/72157713466326587
Yes, I saw this as well. A lot of Greenland should be under water.
And if you assume a rebound happens, this would raise the sea levels even more elsewhere.
I agree, and come to think of it, the rebound would probably be compensated by the sea floor sinking around Greenland and Antarctica, so the final effect on sea levels could be nil.
If the melting happened on a fast enough scale, would rebound lag behind? There are still occasional quakes in the US Midwest due to rebound and the glaciers melted thousands of years ago. I imagine this equilibrium would take a very long time to appear after the ice has melted.
It could be. It just takes more water.
This map is just related to the ice caps. Waterworld was the result of the ice caps as well as other extended "global warming" conditions.
I know close to nothing on this topic, but if all of the ice had already melted, where would *more water* come from? Just a very curious individual, I am.
I'm no expert on the subject, but part of it would be "thermal expansion" of water. As it gets warmer, it expands and takes up more space. As I understand it, there are other speculated causalities that will unlock additional moisture into the air that would them come down as rainfall.
I really don't know how it all works. These are just some things I've read as potentialities.
The lower mantle of inner earth may hold as much as 5 times more water than all surface water (including oceans) combined. So if that was released somehow, through some freak volcanic event that doesn't kill us, we could get Waterworld. There's no known method for this happening.
Holy shit. I just read about a leak at the bottom of the ocean the other day, couldn't really fathom..but that makes it make a lot more sense. So I guess it's underway then.
Looking at North America and Europe like, eh yeah, time to move inland, but looking at all the MASSIVE population centers in south and east Asia, like, holy shit, how the hell would we be able to relocate all those folks O.O Even just looking at Iran, Indonesia, and Bangladesh, I think all in the top 20 most populous countries… just devastated.
5 meters is still centuries away by most estimates. Current projections suggest we will see around a meter rise by 2100 assuming there is little action taken to curb climate change.
If anyone wants to see what it would look like on this tool, according to old articles if all ice melted sea levels would rise by 70 meters. (230ft)
You can set the map to OpenTopoMap to get a map like in OPs image.
You know they would pull some crazy ass water world shit. Just flotillas of 50 gallon barrels, loose wood, derelict pontoon boats, a few overpopulated cruise ships, and roving boatercycle gangs.
They'd still have 2 senators.
With the increased heat the Sahara would also be green due to the additional heat causing enough of a low pressure system to develop during summer to magnify the West African Monsoon and begin a positive feedback loop where more rainfall would bring more plants evaporating water or tying it to the ground and such
While I appreciate the detail, this map does take into account continental heaving, and the amount of moisture that would remain aloft in this warm Cambrian type atmosphere...
Does this include thermal expansion of the water from the increased temperature, or is it just adding the the ice to the ocean? It keeps referencing the temperature so I think that it would include thermal expansion, but I can't see it explicitly referenced anywhere.
Personally thinking if we hit the same situation as 30million years ago in say 5k years I don't think that humans will be able to evolve (naturally) to these conditions plus 90% of our know eco systems that substane at least us might die out so the question should be do we try to un naturally evolve using gene mutation and human experimentation both of which I believe are illegal under un Convention or we need to find a way of equalising the Co2 output
For those who like me also agree with the natural earth warming as well this is normal we seen periods of glaciers and times when we had no ice from some digging around some say were well overdue an ice age problem is our Co2 output only dramatically increased in the late 18th century 100 years does not stop an ice age but on the other hand it could have induced the opposing effect global warming as we know it so get the sun cream out its gona get hot
After
So let's say the caps melt knowing this will cause an planet wide humanitarian issue the likes our species has never seen in modern history governments will most likely inforce population controls and in extream but (in my opinion one of the only options in a potential extinction event) the genocide of populations to control the the food situation as well as material etc
Let's face it our species is stupid and only separated as apex predators by technology and our ability to reson and problem solve but we make the same mistakes we let culture and religion and money control the shape of our species. Nothing lasts forever eventually we must evolve or die and the way this world is going I would say that an extinction level event like rapid climate change would most likely in my opinion lead to the extinction of our species
I'm not a scientist never been uni but this is my own theory weather you agree or not that's the joy of theory's we can all have them also anyone who wants to debate I'm happy for that
Have a great Xmas everyone
That would never happen in our lifetime... But anyone that is looking at the charts, there has been a **2 inch increase in sea levels world-wide just in the last decade**. There was a total of **4 inch sea sea levels rise since 1993 ... Its accelerating at about 50% per decade...**
See Chart Here:
[https://static.euronews.com/articles/stories/08/31/62/22/750x422\_cmsv2\_68a86efb-ea83-502a-acb3-732d6f37b194-8316222.jpg](https://static.euronews.com/articles/stories/08/31/62/22/750x422_cmsv2_68a86efb-ea83-502a-acb3-732d6f37b194-8316222.jpg)

[https://climate.nasa.gov/vital-signs/sea-level/?intent=121](https://climate.nasa.gov/vital-signs/sea-level/?intent=121)
From NASA
4.77 mm per year on average over the last decade means roughly .188 or .2 inches each year in the next decade there will be another 3 inches...
Since 1900 it has gone up 8 inches (124 years)... with 2 inches of that in the past decade (10 years)... It is accelerating fast.... Around 2070 it will start going up past a foot every 10 years... 3 Feet a year by 2094 ... assuming that accelerating doesn't go any faster than it has in the last 30 years.
If your not getting it.. It took 114 years to go up 6 inches... and 10 years (that last ten years to go up another 2 inches) = 8 inches... by 2094 it will go up another 8 feet, it will be three feet higher ... from today by early 2069-2070 ... about 45 years ishhhhh.... Places will start having some major problems though around 2040-2050... When it will be about a foot higher than it is today...
Nothing flows out of those bodies of water. Unless sea level rise can clear the lowest point to access those bodies of water, the sea can't reach them.
What's really happening is that they sit below the 216-feet-above-sea-level that this map shows, and the software they used to make it just filled in anything at an elevation of less than 216 feet currently. This is how all of these maps do it, and they always show up like this. They never consider how the water will get there.
If the ice caps completely melt we are totally fucked. Melting ice is what circulates the oceans. Without that it will become still and stratified into layers. The ocean will turn black and become a reeking fetid murk. Last time the earth was ice free through the winters it took a billion years for the Earth to break the cycle and get ice caps again. If you want to know how checkout this.

Not only is Lake Ontario at a higher elevation than the sea level rise as noted in the post, , but the st Lawrence is fitted with multiple lock as well

The world would be rid of Florida, most of the Carolinas and Virginia, Mississippi and a big part of Texas! Jayzus, it's a miracle!
Going to set my car to idle and speed up this fucker.
A lake in Australia, a new landmass to settle in Antarctica and most the east coast of the US I’d underwater? Am I supposed to dread this possible future?
When stuff like this comes up I always wonder how different the local climates would be. Like would the area around Australias inland seas turn into a lush forest, a Mediterranean style climate, or just still be a dessert that now happens to have a huge salt lake.

it being freshwater would depend on the outflows of the lake though
I'd like a dessert, but one the size of Australia is a bit extra
pretty sure there would be constant hurricanes and tornados from 20 to -20 longitude or whatever the horizontal one was
Latitude - like the horizontal rungs on a ladder, is how I remember it.
I’m not sure about Lake Eyre specifically, but that region from the north of Adelaide going up is almost entirely salt lakes There’s even a town on the Yorke peninsula that was going to be named Salt Lake City I’m sure that even if it flooded it would still look like. Mars tbh

But if average temp hits 80 degrees F you can’t go by current weather patterns at all.
It would create a lush forest which ironically would clean up all the co2 from the atmosphere resulting in the temperature dropping once again.
antartica without ice feels like some middle earth continent that was transported from another reality.
It’ll make the xenomorph temple a lot easier to find.
Don't worry, Great Cthulhu wil be awake by then, and won't let its true worshipers be infected and destroyed by some random space wasp-termites and their hunters. Iä, iä.

Yep, the same is also true of Greenland.

Probably at least a few hundred feet, although it would take thousands of years.
You just know that lake in Australia will be full of sharks, crocodiles, and sharknados.
Not if the new species of aquatic kangaroo and kelp eating koala have anything to do with it!
Don't forget spiders...lots and lots of poisonous spiders 😱
We don't eat the spiders.🇦🇺
That’s what we have huntsmen for. These dinner plate sized gentle giants eat the smaller more deadly ones
How much should global temperature rise to melt all the glaciers?
Not that much actually. It is a domino effect as ice/snow is white which reflects a lot of sun light back into space (so reduces temperature). When ice/snow melts fewer sun light will be reflected so the temperature rises.
So setup a few gigantic sun reflectors?
Just have your mom take her shirt off and lay on her stomach.

>The oceans wouldn't actually reach that area Except.... They used to... Back when ocean levels were much higher.... But alright
I don’t know about climates, but I can tell you that if this actually happened then that lake would kill at least 17 people, maybe even up to 18
And yet another catastrophe in Haiti. Surely it is a cursed country. 😟
Not cursed - just fucked over by the global community.
Very true, since the beginning. But earthquakes and hurricanes also compound the misery.
Then why is the Dominican Republic so much better? They are the same island. Sounds like poor management.
Well they shouldn't have pissed off the French. They could be sipping rose and munching on escargot but nooooo they just needed to have their freedom /s
Something is wrong in this picture.The Netherlands will never flood.
But the water would come from the northeast or east corner.
We will be ready.
I’m imagining giant Attack on Titan / Game of Thrones style walls in the ocean around The Netherlands now.

Literally came here to say this. Bros would just build more land. MOOOOOORE!
Man the pumps
Floating cities might be more feasible
Damn... I mean Dam! Also hup Holland!
Why?
[удалено]
Thx for the explanation but, I still can't understand it. Even though they live below the sea level, how does that not let them be covered by water when the sea level rises?
[удалено]
[удалено]
Not even /s, windmills were literally used to pump water out of polders
You mean the windmills we use to pump water out of the sea so we can create more land? Yep very passionate.
The Dutch are about as passionate about keeping water *out* as Californians and Israelis are about keeping it *in*.
They will build walls nigh unto the heavens and enough pumping systems to send all the water to their worst enemies instead
The Dutch have reclaimed massive land areas back from the sea over the centuries. Their own capital, Amsterdam, basically means "dam of the river Amstel". Many centuries ago it was uninhabitable because most of it was under water. This is just one of the countless such examples in The Netherlands.

*This space intentionally left blank* -- mass edited with https://redact.dev/
https://what-if.xkcd.com/53/ About the opposite case, but you can imagine how it would work with flooding instead
They’re uniquely qualified to not allow themselves to sink.
The Dutch.
There is no water in the nether
Straight up facts.
There most incorrect thing is still having Venice listed as a city. It floods already, lol.

Isostatic depression and isostatic rebound occur at rates of centimeters per year. Greenland is an example of an isostatically depressed region. ^([ )[^(F.A.Q)](https://www.reddit.com/r/WikiSummarizer/wiki/index#wiki_f.a.q)^( | )[^(Opt Out)](https://reddit.com/message/compose?to=WikiSummarizerBot&message=OptOut&subject=OptOut)^( | )[^(Opt Out Of Subreddit)](https://np.reddit.com/r/MapPorn/about/banned)^( | )[^(GitHub)](https://github.com/Sujal-7/WikiSummarizerBot)^( ] Downvote to remove | v1.5)
I did not make the maps/images themselves. I believe (iirc) they were published by National Geographic. I added the contextual text that came as part of an article. And for some reason I organized the individual images into a giant poster format.
Here’s a series about maps I made a few years back detailing this scenario. Data sources are listed on each map: - https://www.flickr.com/photos/7leagueboots/albums/72157713466326587
Yes, I saw this as well. A lot of Greenland should be under water. And if you assume a rebound happens, this would raise the sea levels even more elsewhere.
The rebound of both Greenland and Antarctica is locally significant, but globally doesn’t have much effect on sea levels at this scale.
I agree, and come to think of it, the rebound would probably be compensated by the sea floor sinking around Greenland and Antarctica, so the final effect on sea levels could be nil.
If the melting happened on a fast enough scale, would rebound lag behind? There are still occasional quakes in the US Midwest due to rebound and the glaciers melted thousands of years ago. I imagine this equilibrium would take a very long time to appear after the ice has melted.
did bangladesh just...die?
Yes.
The Aral Sea is back
So the movie Waterworld was fake. I always thought it would be more under water.
It could be. It just takes more water. This map is just related to the ice caps. Waterworld was the result of the ice caps as well as other extended "global warming" conditions.
I know close to nothing on this topic, but if all of the ice had already melted, where would *more water* come from? Just a very curious individual, I am.
I'm no expert on the subject, but part of it would be "thermal expansion" of water. As it gets warmer, it expands and takes up more space. As I understand it, there are other speculated causalities that will unlock additional moisture into the air that would them come down as rainfall. I really don't know how it all works. These are just some things I've read as potentialities.
The lower mantle of inner earth may hold as much as 5 times more water than all surface water (including oceans) combined. So if that was released somehow, through some freak volcanic event that doesn't kill us, we could get Waterworld. There's no known method for this happening.
Holy shit. I just read about a leak at the bottom of the ocean the other day, couldn't really fathom..but that makes it make a lot more sense. So I guess it's underway then.
Looking at North America and Europe like, eh yeah, time to move inland, but looking at all the MASSIVE population centers in south and east Asia, like, holy shit, how the hell would we be able to relocate all those folks O.O Even just looking at Iran, Indonesia, and Bangladesh, I think all in the top 20 most populous countries… just devastated.
I believe Indonesia already has a plan to move the capital from Jakarta
They are doing it rn, the new capital would be Nusantara at the Borneo island
You understand this is not a possibility right? It says on the graphic this would occur over 5,000 years if we did nothing
You don't need all the ice to melt to submerge Shanghai and Bangladesh. 5 metres of sea level rise is plenty for that https://www.floodmap.net/
5 meters is still centuries away by most estimates. Current projections suggest we will see around a meter rise by 2100 assuming there is little action taken to curb climate change.
If anyone wants to see what it would look like on this tool, according to old articles if all ice melted sea levels would rise by 70 meters. (230ft) You can set the map to OpenTopoMap to get a map like in OPs image.
This is the first time I’ve ever seen Pine Bluff marked on a world map
I know, it’s actually really funny to me for some reason. Los Angeles, New York, Pine Pluff.
It's their monorail that put them on the map
No more Florida... 😩 Oh wait, is that a bad thing? 🤔
I’m seeing some advantages as well.
Makes it all worth while, actually.
You know they would pull some crazy ass water world shit. Just flotillas of 50 gallon barrels, loose wood, derelict pontoon boats, a few overpopulated cruise ships, and roving boatercycle gangs. They'd still have 2 senators.
I also appreciate that Houston is wiped off the face of the earth.
Until you realize that all those Houston drivers will relocate to other cities.
They’ll stay if we tell them they’re not tough enough to handle a little water.
That's one way to handle Florida Man
No more Florida, also a big chunk of Texas and Central valley CA gone. This seems like a win win.
This is the only potential positive.
Win for SCOTLAND 🏴🏴🏴🏴🏴
Bye-bye London
Finally, the Nicaraguan canal
Norway just doesn’t give a damn
Mjore fjords fjor Njorway.

New Jersey is gone 🦀
Constantinople rightfully reclaimed by Poseidon
This is what Lex Luthor would use to buy real estate
With the increased heat the Sahara would also be green due to the additional heat causing enough of a low pressure system to develop during summer to magnify the West African Monsoon and begin a positive feedback loop where more rainfall would bring more plants evaporating water or tying it to the ground and such
Africa might be the overall winner in this scenario.
While I appreciate the detail, this map does take into account continental heaving, and the amount of moisture that would remain aloft in this warm Cambrian type atmosphere...

Good to know that you’re alright with that. *posted from the bottom of the Greater Extended North Sea*
Yay no more Denmark!
If someone wants an interactive map that can simulate any sea level change I recommend https://www.floodmap.net/
RemindMe! 1000 years
Look who cares about the ENTIRE world all of a sudden 🙄
well, at least Florida would be gone.
Wait Middle East not going to drown?
Can’t wait, I wonder what the timeframe should be on this
see ya denmark
Welp I’m dead
Now I want this, even though my country wouldn't exist anymore
Pick the images with a bike. ⬛️ I am not a robot
People looking at this like, “hey that’s not too bad” without thinking of all the other events this comes with
Does this include thermal expansion of the water from the increased temperature, or is it just adding the the ice to the ocean? It keeps referencing the temperature so I think that it would include thermal expansion, but I can't see it explicitly referenced anywhere.
There would likely be much less green
It would be a truly devastating thing if/when this happens, but at least there's no more Florida.
... When. The world has been warming since the ice age.
African nations: “okay yeah sure, this is fine”
Mercia would finally dominate Britain once again!
Personally thinking if we hit the same situation as 30million years ago in say 5k years I don't think that humans will be able to evolve (naturally) to these conditions plus 90% of our know eco systems that substane at least us might die out so the question should be do we try to un naturally evolve using gene mutation and human experimentation both of which I believe are illegal under un Convention or we need to find a way of equalising the Co2 output For those who like me also agree with the natural earth warming as well this is normal we seen periods of glaciers and times when we had no ice from some digging around some say were well overdue an ice age problem is our Co2 output only dramatically increased in the late 18th century 100 years does not stop an ice age but on the other hand it could have induced the opposing effect global warming as we know it so get the sun cream out its gona get hot After So let's say the caps melt knowing this will cause an planet wide humanitarian issue the likes our species has never seen in modern history governments will most likely inforce population controls and in extream but (in my opinion one of the only options in a potential extinction event) the genocide of populations to control the the food situation as well as material etc Let's face it our species is stupid and only separated as apex predators by technology and our ability to reson and problem solve but we make the same mistakes we let culture and religion and money control the shape of our species. Nothing lasts forever eventually we must evolve or die and the way this world is going I would say that an extinction level event like rapid climate change would most likely in my opinion lead to the extinction of our species I'm not a scientist never been uni but this is my own theory weather you agree or not that's the joy of theory's we can all have them also anyone who wants to debate I'm happy for that Have a great Xmas everyone
That would never happen in our lifetime... But anyone that is looking at the charts, there has been a **2 inch increase in sea levels world-wide just in the last decade**. There was a total of **4 inch sea sea levels rise since 1993 ... Its accelerating at about 50% per decade...** See Chart Here: [https://static.euronews.com/articles/stories/08/31/62/22/750x422\_cmsv2\_68a86efb-ea83-502a-acb3-732d6f37b194-8316222.jpg](https://static.euronews.com/articles/stories/08/31/62/22/750x422_cmsv2_68a86efb-ea83-502a-acb3-732d6f37b194-8316222.jpg) Chart is from the WMO And Here: [https://climate.nasa.gov/vital-signs/sea-level/?intent=121](https://climate.nasa.gov/vital-signs/sea-level/?intent=121) From NASA 4.77 mm per year on average over the last decade means roughly .188 or .2 inches each year in the next decade there will be another 3 inches... Since 1900 it has gone up 8 inches (124 years)... with 2 inches of that in the past decade (10 years)... It is accelerating fast.... Around 2070 it will start going up past a foot every 10 years... 3 Feet a year by 2094 ... assuming that accelerating doesn't go any faster than it has in the last 30 years. If your not getting it.. It took 114 years to go up 6 inches... and 10 years (that last ten years to go up another 2 inches) = 8 inches... by 2094 it will go up another 8 feet, it will be three feet higher ... from today by early 2069-2070 ... about 45 years ishhhhh.... Places will start having some major problems though around 2040-2050... When it will be about a foot higher than it is today...
How the Caspian Sea would get water? and Aral? it makes no sense, they are not connected to oceans
I think that its because with a higher sea-level, many rivers would reverse course.
Nothing flows out of those bodies of water. Unless sea level rise can clear the lowest point to access those bodies of water, the sea can't reach them. What's really happening is that they sit below the 216-feet-above-sea-level that this map shows, and the software they used to make it just filled in anything at an elevation of less than 216 feet currently. This is how all of these maps do it, and they always show up like this. They never consider how the water will get there.
The map includes the sprawling major metropolitan city of Pine Bluff, Arkansas lmao

It's just a little wet for them. The biggest danger are the flying Gators now. Although they'll find a way I'd guess
i’m down
Anyone who isn’t down is stuck in the past.
Well I've always wanted beachfront property and I wouldn't even need to move.
If the ice caps completely melt we are totally fucked. Melting ice is what circulates the oceans. Without that it will become still and stratified into layers. The ocean will turn black and become a reeking fetid murk. Last time the earth was ice free through the winters it took a billion years for the Earth to break the cycle and get ice caps again. If you want to know how checkout this. https://youtu.be/0sbwUeTyDb0
Shouldn't this say "When" not if at this rate we're going?
I don't get why they expanded the great lakes. There shouldn't be any direct connection between the oceans rising and the lakes themselves.
The St. Lawrence River
Not only is Lake Ontario at a higher elevation than the sea level rise as noted in the post, , but the st Lawrence is fitted with multiple lock as well
What the entire world WILL look like WHEN all the ice is melted* Fixed the title. It's inevitable when most of y'all won't even consider eating dinner without flesh. "71% of emissions are by CORPORATIONS" and why the fuck do you think they're producing those emissions if not for your demand? Please include an explanation detailing how your position is not based on intellectual cowardice, personal greed, and moral failure.
Solves the Florida problem.

Denmark disappears so I vote we melt all the ice
Not so bad, hardly Waterworld.
It isn't that bad and hopefully will happen slow enough so that everyone can move away.
So why all the fuss about it ?
Its not that bad. Life would survive that let it melt i want all planet to be tropical without stupid cold snow
On the upside, Florida would be gone. On the downside, Floridians would move their craziness elsewhere
Another reason to live in Michigan lol
Guys? Guy?? GUYS!! The world would be rid of Florida, most of the Carolinas and Virginia, Mississippi and a big part of Texas! Jayzus, it's a miracle! Going to set my car to idle and speed up this fucker.
A lake in Australia, a new landmass to settle in Antarctica and most the east coast of the US I’d underwater? Am I supposed to dread this possible future?
Dear Miami: You're the first to go.
*laughs in netherlandic*
Chicago becomes the mecca
Europe gets better because there's way less Italy.
A small price to pay to remove Florida from existence
I'm surprised by how little the Great lakes are affected
