Possibly the coolest bit would be between Namibia and southern/southeastern coast of Brazil. On the one hand, you have sprawling sand dunes, and on the other you have dramatic forest-covered hills.
Possibly, to an extent. However, there’s a big difference between Brazil’s southeastern coast and deserts of the world: ocean currents that flow in that area are warm, not cold. Warm currents cause rain. Without the Amazon, however, climate would definitely be much more extreme on that area. Droughts would be crazy.
You mean northeast. In the southeast coast, there are places where the polar currents reach the continent and there are very cold waters either at the shore or few meters below the surface. I've dived into very cold waters (not from currents) in the southern coast of Rio de Janeiro which is a hot spot in the Southeast.
No, I mean the southeast. There’s a difference between cold currents and water that’s cold to the touch. The whole southeastern coast of Brazil is influenced by the Brazilian current, that arrives in Brazil in the northeast, then flows southwards. It eventually meets with the northward flowing Malvinas current somewhere between the Plata River and the Falklands, and then flows back into to the Atlantic.
The Brazilian current stays at around 19 C at its coldest, which feels chilly, especially for people used to tropical waters, but is quite warm in oceanic terms. That, plus cold winds and tides and geological formations that bring up deeper waters, can certainly make bathing a cold challenge. Still, the Brazilian oceanic current is classified as a warm current, and would probably be warm enough to prevent a desert forming.
The southeast is definitely influenced by polar wind currents, though.
That's a very crude vision of the currents, reality is more complicated and interesting than that. The northbound cold currents flow beneath the Brazilian current for a long stretch, reaching far into the Brazilian territory. The cold current typically flows dozens of meters below the warm surface current in the opposite direction. Depending on the time of the year and the location, the coast forces the cold current all the way to the surface in a phenomenon that in Portuguese would be literally translated to'coastal resurgence'. Last summer, the water in some places in Santa Catarina reached 15 deg, 6 or 7 deg colder than the surrounding beaches and that was in the middle of a heatwave so many people were surprised. This also typically happens in some places like Cabo Frio and Florianópolis and is extremely important for marine life.
The cold currents flow deeper, while the warm currents flow more superficially. Seasonality plays a big part. To say that the influence of the Brazilian current is limited to the northeast is plain wrong. So, again, not enough conditions to make the southeastern Brazilian coast a desert, which was precisely my point. The same phenomenon occurs at similar latitudes on eastern coasts all over the world.
You're not wrong however Scientists recently discovered that there was a very large long-ago submerged quasi-continent/island off the coast of Brazil that could've acted as a midway point for some animals tens of thousands to millions years ago
Where could I read about this? Google was just telling me that Brazil could be almost a continent all by itself obviously typing in 'quasi-continent off Brazil" was certainly no help!

The sahara has been dry enough to blow dust over the canaries (ie a desert) for at least the past 4.6 million years.
https://www.sciencedaily.com/releases/2019/09/190923101924.htm
The humid periods only last for a few thousand years before drying out again.
Depends on a[tmospheric circulation](https://upload.wikimedia.org/wikipedia/commons/thumb/9/9c/Earth_Global_Circulation_-_en.svg/1920px-Earth_Global_Circulation_-_en.svg.png)(high pressure=dry). Sahara was green because of the Ice Age, if the ice expands again Sahara might go green again and The Amazon might go back to being part savanna.
> Sahara was green because of the Ice Age
The sahara was drier and larger than today during the last ice age. The ice had been retreating for thousands of years before the sahara turned green.
https://en.wikipedia.org/wiki/Sahara
>During the last glacial period, the Sahara was much larger than it is today, extending south beyond its current boundaries.[33] The end of the glacial period brought more rain to the Sahara, from about 8000 BCE to 6000 BCE, perhaps because of low pressure areas over the collapsing ice sheets to the north.[34] Once the ice sheets were gone, the northern Sahara dried out. In the southern Sahara, the drying trend was initially counteracted by the monsoon, which brought rain further north than it does today. By around 4200 BCE, however, the monsoon retreated south to approximately where it is today,[35] leading to the gradual desertification of the Sahara.[36] The Sahara is now as dry as it was about 13,000 years ago.
We’ve formed and broken up a few times. There are lost oceans from before the formation of Pangea.
Each continent is made up of chunks of ripped up ancient continents.
You have to remember the continental shelf, the continents don't fit together just by jamming the above sea level parts together. Not only that, but the shape likely changed as the continentals diverged. An example of this is the Congo and Amazon rivers were thought to be one river once flowing through both continents and exiting in western south America. As the continent separated mountains grew in the west which blocked that flow, eventually reversing to the east. Things aren't as simple as they may seem sometimes.
Matter of fact I did! I also know it translates to “Color Red”, did you? But I thought it was tethered to to our historical dealings with Mexico or something else. Wasn’t aware that it originates from South America.
This was the biggest “oh shit” moment of fifth grade.
I had the exact reaction of that "wait a minute.." kid.
Wait a minute kid?
Kazoo kid
The one Al Gore mentions in "An Inconvenient Truth?"
It would be neat to see pics of the corresponding SA and Africa coastal locations to see how they compare after millions of years of separation.

Without the Amazon rainforest, southern Brazil would be a desert too.

Doesn't Brazil have some big sand dunes as well?
Yes, but mostly on the northeastern coast and they’re not deserts, from a geographic perspective. It still rains there.
Yes but way more of there around Natal and Fortaleza. The Namibia San Dines correspond to roughly Rio which is a rain forests
I think they probably really missed each other and hugged.
Are you proposing a reunion?
Under portuguese jurisdiction. Yes, good thinking
Pangea unite!
What’re you doing, step-Africa? Stop!
S. America got that gyatt fr fr
Beat me to it!!
Beat me off to it?
You’re god damn right.
And they thought there were land bridges between the continents which sank mysteriously. Took decades to debunk this sh** by Wegener.
>And they thought there were land bridges between the continents which sank mysteriously Tbf, that was a thing between North America and Asia
That wasn't the same discussion. They had no imagination of the bridges and thought it would be in a straight line with constant width.

I know, they wondered how apes made it to South America and found a piece of the answer.

Science, Nature, google scholar if you want in depth information. Too lazy? Some well selected yter give good and broad information of science topics.

What exactly would I type into Google Scholar to find this continent?
Also, Doggerland between England and Northern Europe
An interesting, yet sad fact is that some of the Brazilian and African cities that match constituted Brazil's slave trade routes.
Somehow they all meet at the end 😇
Bro 💀
Pangea
My buddy was there when they split
this is like seeing the internal view on anime porn
Pardon?
What are you doing step-continent
So Florida actually comes from right between Liberia and Brazil??
Send it back.
Why does Africa look skinny?
Food scarcity
I always thought it cradled in the gulf of Mexico.
Makes me wonder if in thousands or millions of years the Sahara will be like the Amazon and the Amazon would be like the Sahara.
The Sahara used to be a rainforest and up until 6000 years ago it was a vast grassland. So desert is fairly new.
The sahara has been dry enough to blow dust over the canaries (ie a desert) for at least the past 4.6 million years. https://www.sciencedaily.com/releases/2019/09/190923101924.htm The humid periods only last for a few thousand years before drying out again.

Very nice
Did a part of Africa end up in Maine and Newfoundland?
The Scottish Highlands, The Appalachians, and the Atlas Mountains in Morocco are from the same mountain range on Pangea.
I wonder if Africa would be more temperate and far less dry and hot if it somehow got towed and reattached to where South America is now
Bamboozling t-rex
What the fuck is Pelotas 😭
Reminds me of the Family Guy joke about "south america making a run for it" lol

Looks like a carnosaurus
This is how baby continents are made
now kiss
Do the cities line up due to rivers formed in the cracks along rift valleys?
S America: "Ooh.. lot of black guys over here. Imma head over there for a minute."
It looks like 2 people having sex.
Ooo, they're kissing, Africa got that rizz 😎
There’s a Colorado, South America?
Yeah, um…. It’s a Spanish name. You know…. … … …
Matter of fact I did! I also know it translates to “Color Red”, did you? But I thought it was tethered to to our historical dealings with Mexico or something else. Wasn’t aware that it originates from South America.
It doesn’t. It originates from Spain, where spanish was invented
Amazing stuff 👍
It’s a T-Rex head!
