The Geography of the Ice Age
Вставка
- Опубліковано 17 кві 2020
- Only a few thousand years ago, the planet's geography was drastically different than it is today. Massive ice sheets stored atop the poles lowered sea levels and exposed a number of interesting and very real geographical features. Let's explore this fascinating landscape, and see what we can learn from it!
I definitely missed a couple things so find me on twitter @theatlaspro to see the full map for yourself!

We sure did
Aw frick yeah
Your welcome bro

Paolo G new zealand was discovered bij Abel Tasman who was from the Netherlands. In the Netherlands there is a province called Zeeland, this is how it got its name.
I would like to see how nature reacted to these shifts in climate

Subbed for being selfless, sympathetic to the suffering of strangers, and refusing money. Most people would just explain it away, and ask for money anyway. I haven't seen anyone on any other channel do this, no matter how rich they are, or how many subscribers they have. Kudos to you sir. Class act all the way.
I wish I had a geography class like this during my school years. I would certainly love this topic way more than I already like today. That's some phenomenal work right here, loved it!
I would advise consulting properly documented books and articles
I've never heard someone admit that a hardship (i.e. the pandemic) is not affecting him financially, and therefore encourage others to stop supporting him financially if they are struggling. That's amazing! Way to go, Atlas Pro. That's generosity! I'm a big fan now!
Wow
'Selfless"

Jimmy Dore ends his videos saying something like nobody's got any money now so just enjoy the video instead of his old ending about subscribing for premium levels.
Indeed. I was taken by surprise too, but then, in my devious mind, I also thought that this perhaps is one of the smartest strategies you could employ to ensure continued support for your UA-cam endeavors. Nobody else says that, and who would actually withdraw his support from such a nice guy? This said, I found the research convincing, the presentation great and the graphics excellent. Well done, dear Sir!
@@TheZodiacz I was gonna bring up JD.🤣
Heard it from Reddx and Urban Ghost Urban Exploration but yeah that's cool
Asking people to stop supporting if they’re in need of the money makes me wanna give him money
Reverse psychology.
Philippines is on the right side of the Huxley line (revised from earlier Wallace line), therefore is not connected to the Sunda basin except Palawan Islands. For the most part, the Philippines is like another Wallacea and shares elements of Australian flora and fauna.
Well in that case, do not under any circumstances give me about tree fiddy.
you could give to a charity, in his honor, like meals on wheels or something.
Sun S you know so much! But not how to comment?
Sundaland
in the ice age, tropical seasonal snow can fall to an altitude of 3000 meters, at an altitude of 3200m-3600m tropical glaciers appear, so Mount Semeru, Rinjani and Kerinci with their current height can have glaciers
Mount Kinabalu also has glaciers,The Leuser Mountains in Aceh often snow,Mount Rantemario in Sulawesi often snows, and Papua (Sahul mainland) has many ice fields.
Africa even has receding glaciers now
Do you know what's cool? The aboriginals in Australia actually have oral stories that go back to the end of this period (20 000 year ago). They tell stories about giants flooding the coastlands (the bridge between Australia and Papoea-New Guinea disappearing). These are the oldest human stories that we know of.
some would say the Biblical flood is this very story, the end of the Ice Age along with catastrophic ice melt off and oceans rising (meltwater pulse 1A). all that weight coming off the poles caused the previous land bulge to sink. So the oceans rose, and the land sank. A hell of a time to be alive
Mythology can't be relied upon as evidence
@@unm0vedm0ver There's a big difference between 6,000 years and 20,000
Their story is dated to only 1000 years ago for the waters covering Great Barrier Reef according national geographic
@@drinno8900 Place was already under water by then
Dude, saying to people to not give money if they can't and letting them know they shouldn't feel guilty or obligated is an incredibly honorable thing to do. subscribed.
Me: studying is giving me a headache. I need a break.
Atlas Pro: do you want to know the geography of the ice age in 15 minutes?
Me: yeah, sure
Procrastination? Or classes too boring?

if we assume that humans lived near the coasts and river banks as we can see today, just imagine how many totally unknown civilizations could have existed in all those lands that are now at the bottom of the sea.
There's one should fit the bill.
Atlantis
@@zethzune4997 I read as a kid that Atlantis was described as being on a pear shaped island.
Many including pyramids.
None.
You guys do realise that this ice age ended tens of thousand of years ago? The first accounts of humans forming civilizations date from a few thousand years only... I am very doubtful about "ice age civilizations"
I wonder what archeological finds are left to be discovered underwater. Doggerland is just one amazing discovery.
Exactly! Yet the vast majority of archaeologists discount the idea that searching underwater is pointless and there’s nothing there!
Check out Graham Hancock and Randall Carlson on Joe Rogan’s podcast talking about it!
Fascinating dude’s!
Near Kuba is a sunken City, that has 4 pyramids, wich all are bigger then the biggest of Gizeh.
Its located 200 m under sealevel.
Edit: Not 200 m, its 650 m sorry

You might be interested in a book called, "The Archaeology of Beringia".
If there is anything to find it would be buried deep in the mud. Also I imagine nearly all structures would've been wooden so may have rotted but the lack of oxygen on the other hand may have prevented this. I suspect we'll have to wait for the next ice age to be well advanced before any excavations could begin 😔
I find the difference of landmass during and after the last ice age so interesting, and it sure helps a lot to see it illustrated on maps. Thank you for the video!
Did you do a biogeography of the ice age? I’d be interested to know what australia was like then, whether there were still large portions of desert, and what the time periods were…
he did
he did 2 years ago
And what the indigenous peoples were doing at the time. Apparently they've been here for 40-,60,000yrs (they can't decide on the number.
I’d like to see the biology of that time
It was incredible, basically same as today but with so much more biodiversity, and megafauna.
Not much honestly.
On the other hand I wonder what the fauna at the time of Pangea was like? Especially the marine fauna, because most of earth was an endless sea
@@fabiovezzari2895 It depends when we are talking. When Pangea first formed there was incredible bio diversity, with many old organisms like trilobites and ancient types of coral still around, and on land many large amphibians and reptile-like mammal ancestors. However closer to the end of Pangea was in the midst of the greatest mass extinction earth has ever seen, and so bio diversity was at an all time low, with 70% of land species and 96% of marine species being wiped out.
@@ikeartfilms7783 what caused the extinction event?

I usually would watch such a video on the side, but it was too interesting and I was glued to it.
Really good explanations, nice flow and amazing narration!
It's fascinating to think about how history and society would be different if the ice did not retreat
i want to hear about how things were affected by the ice ageee
Seconded when it comes to the biogeograhy here.
It was more icey
@@bojabang2188 thats what i needed to hear😂
Well If Didn't Have Ice Age There Would Be No More Ice Age Baby
Uhh... What do you mean?
I live in an area that was just at the edge of the last ice sheet. When I was learning about this in college I would bore my friends to death by pointing out the areas that the glaciers didn't reach. I never tire of reading about it or watching videos like this because I always learn something new. Thanks!
I live near an area where you can see the scratches on the rocks from ice sheets passing over them, although from the Permian Glaciation (290 million years ago). Even though I think the striations are fascinating, so few people do.
@@TheZodiacz how did the last ice age come about?
Where is this
@@jazzjj7665 Between Central and Southern Indiana, USA.
@Vaylen Schultz Alfred E. Neuman
I live in southwestern Wisconsin, known as the Driftless Area, a great example of what the landscape looked like before the glaciers ground down the high areas and filled in the lower areas.
I am living near San Francisco, California. I read someplace that 20k BC (old school here), ice bergs and broken ice sheets were seen off northern Calif coast… that expanded out 80 miles… and local mountain high enough probably had snow for a good chunk of the year. Also, mike high glaciers carved out many valleys in the Sierra Nevada (Yosemite valley… at only 4500 feet).
I learned about this in geography, it's basically the reason why Scotland has a massive dip in the middle where the majority of people live. I literally live in a bowl made out of rock that looks pretty in the winter.
I think it's a similar story in some parts of NY.
The fact that you don't have annoying advertisements in your videos, is really nice.
The ice sheet over Canada expanded and contracted as seasons changed and in one unique location, they expanded and followed mountain valleys in to today's Washington State like snakes of ice which were miles thick and at a few locations they would expand in to each other and crashed in to one another over and over. This incredible force caused the ice sheets to dig down in to the earth creating today's Lake Chelan at almost 1500 feet deep. Also as the ice sheet over Canada grew and contracted it rounded off some of the lower elevation hills and mountains in the Cascades making them look much older than they really are.
What a great, educational channel. I'm always on the edge of my seat waiting for your next installment. PLEASE, keep going and tell us about the biological/evolutionary effects of the glacial periods.

i really want to know the climate on the land bridge between Australia and New Guinea!
will it be just like the barren australian outback? or will it be full of lush rainforest covering the land bridge?
The interior for the most part is still barren desert, the north however was lush rainforest, for the landbridge, i think it was a grassland
@@yatowbvideo4475 I forgot that a lot of the deserts that we see today are jungles back then. I've read that around 40,000 years ago the monsoon failed resulting the already shrinking rainforest to be permanently lost. Im leaning towards that the landbridge back then were covered in rainforest..
@@AyedUA-cam like with the sahara which at one point was very green. As was Antarctica which was tropical before it moved down south
Well North Australia is also covered with tropical/subtropical forest, and New Guinea is covered with tropical rainforest so it probably was forest/swamp region.
Excellent question.
In general would depend on latitude. Near equator I speculate that it would be tropical rain-forest, with the emphasis on speculate. I don't know if there would be three wind-belts. Modern earth has easterly trades near equator, westerlies in mid latitudes and polar easterlies high latitudes. The boundary between the trades and westerlies is a broad area of descending air which creates the largest deserts. The boundary between the polar easterlies and mid-latitude westerlies creates up-lift, air mass fronts and mid-latitude cyclones, that stuff that's drawn on a weather map.
I presume these wind belts would be narrowed with the least affected regions in areas with lots of ocean and closer to the equator.
Man I love this channel.
It's one of the best geography channels on youtube and I absolutely love it!
Keep up the amazing work and thanks for the interesting and educational videos.
Stay safe and good luck atlas pro!
Did anyone else note the temperature peaks at 330,000 and 130,000 years ago are significantly higher than the current average?
One other point of interest not covered in this presentation is the canyons at the mouth of the Hudson River and Chesapeake Bay.
Great video as always. I'm from Indonesia and your pronunciation for the islands of Indonesia was spot on. Kuddos for you man.
Australia or "Sahul" would've been equal in size to Antarctica back then?

Just Some Guy without a Mustache The only difference now is our deadly species are more condensed! Easier to spot!😈🤣
I would LOVE to see the climate distributions of the ice age
Just as an example, there was a whole ecosystem south of the ice that doesn't exist today, the mammoth steppe or "tundra steppe", which was more productive and favored large grazing animals that can't live there now. Read R. Dale Guthrie's "Frozen Fauna: the story of Blue Babe" for the details.
There are critters (monkeys, porcupines) and trees that found their way from Africa to South America. One theory is there were ice ages so severe that islands appeared across the Atlantic so things could hop across. Would love to see you tackle this story too!
No, I think you must go much, much further back to find a common ancestor when Antarctica connected South America to Africa..the Atlantic between Africa and South America is miles deep for over a thousand miles..a depth which wouldn't have been impacted by the ice age ocean recession for migratory purposes
What a Crystal clear sum up of ice age coastlines. And what integrity in your closing statement on earnings. 👌🏽👌🏽👌🏽
I would love to see how nature had changed ( :

Your research is so good! For example, when you mention the Wallace line at 9:53 you show us the map from the original paper by Alfred Russel Wallace from 1859.
This video was very interesting. Definitely worth to spend my 15 minutes of my life on this video. I think it is fascinating in how it once was and how the world changed so much.

I always wondered why everybody went on about the Ice Ages in the Northern hemisphere while ignoring the Southern - I put it down to Eurocentrism, most scholars being in the Northern hemisphere, which [of course] made it much more important! I'd assumed that the ice would advance and retreat similarly in both hemispheres. Now at last I can see why the Southern Ice Ages weren't much on the agenda.

Greetings from Sweden.
Keep up the great work with this channel!
Of all your videos this is one of the most interesting. A very different geography in a world in which all continents are already in their modern positions but the ice and sea level make it distinctly dissimilar. The giant glacial lakes must have been an amazing scenery. And this is the world where homo sapiens lived most of it's time on earth despite being very alien to us contemporary homo sapiens.
One of the more underrated channels out there.
Amazing content.
So much effort.

I've been looking for something like this. Imagine all the archaeological sites at the edges of those ancient coast lines. So much of our history must be lost down there.
You're in the right!! But I don't think you could find something today. Theses are too old as geologic's mouvements make all traces entirely dissapear.
But is it possible than a civillisation are suffisently advance at theses time to survive by knowlege of develloped technology?? I think it's very possible. They could be them of UFO's seen today. Next to be..

You're Chinese. You're not the native of Taiwan/Formosa Island.
The native of Taiwan are the AUSTRONESIANS. The people of Malaysia, Indonesia, Brunei, Philippines, Pacific Islands, Papua New Guinea, and the native Australians.

We actually have the Saalian glacial to thank for the only notable hills in The Netherlands (with the exception of the very south east). The most notable regions being the Utrecht Hill Ridge and the Veluwe.
They formed as push moraines - aka the glaciers actually pushed dirt, rocks and soil from the north with it and where the glaciers ended the land it took with it formed hills.
Now those two areas are one of my favorite parts in the whole country. Just look up 'Posbank, Veluwe' and you'd understand why. :D
I remember visiting the Posbank one time and I felt like I walked into a fairytale, how could the Netherlands, a sad pancake, have such a beautiful landscape?????

Is that the Australian version of walking 5 miles a day to and from school in the snow, uphill both ways every day?
@@daydreamer8662 I guess if you have to walk to the 'future sea bed' and up again to the 'future mainland' it would be uphill and down dale both ways.
@@johnzuijdveld9585 Quips aside, aboriginal Australians settled about 50,00 years ago, whilst Tasmania separated from Australia about 11,500 years ago.

It's insane to think about, that during the last Ice age, it was possible (landwise) to walk from the North Pole to the South pole, essentially walking half way around the Earth. Another fun thing to think about, is that every continent was reachable by foot, besides Oceania. Just goes to show you, how much the Earth has changed, over such a "relatively" short time.
According to this video the continent of Australia was not reachable by foot from any other continent.
@@edmartin875 Australia is part of Oceania.
@@ourtinytownhome-stead So? Australia (then Sahul) was not connected to Sundaland (the continental part of Asia during the last ice age) because the ocean separating Australia and Asia does not consist of shallow shelfs, but also of way deeper ocean. This is why the Wallace line (and other lines) where discovered by early explorers like.. you guessed it: Wallace. These relatively small but deep parts of ocean between nearby islands prevented much of the Pleistocene fauna from spreading from Australia to Asia and vice versa. This is actually still visible in modern the species distribution.
@@kopflosersalat5457 very interesting information there. But how come the water is deeper along the Wallace line? Is it because of tectonic plate boundaries?
Regarding Rebecca's comment, she was clarifying that australia is in Oceania since the comment before that implied that it was located elsewhere.
How far could one walk in these freezing conditions?
Excellent explanation of the facts over a very long period of time . .
In Wisconsin there is an area called, Kettle Morraine and we are told it is where glaciers advanced and retreated a couple times causing the Moraines to form. That is maybe 40 miles west of Milwaukee sort between it and Madison.

Very interesting indeed. As an Australian, I've often wondered if the southern hemisphere was as affected by ice ages as the north but the earth south of the equator never rated a mention. Thank you for fighting my ignorance.
As a fellow Aussie, I can tell you that, IIRC, it's generally thought that, although Sahul didn't see the sort of ICE build-up that the Northern Hemisphere saw, what it did see was a great increase in RAINFALL. Think of the way that all that extra land affected ocean (inter-island seas) currents and wind patterns. Thus the MONSOONS.
Thus, while the North had its ICE AGE, the South had its PLUVIAL AGE (Age of Rain). South America, with its Andean rain-shadow effect, perhaps less so.
So well presented thank you
You really do a fantastic job with these videos! I know many an archaeologist in your debt.
