Planetocopia Map Thread

@Molotov Jack and @Halogen did this map as a fun exercise involving mirrored America as a spinoff of mutually upcoming mapping projects.

Granted, if we were to add a little more realism, the new Aleutians would probably blunt the mid-Atlantic current, resulting in northern Britain and mainland Europe being cooler or at least more continental than otl, but it does look like a fun TL to live in.
I imagine South America would be settled by Polynesians ITTL, at least the Tropical Savanna region between the two deserts. On another note, I'm interested in seeing what you two have got in store with those mapping projects.

Well Molotov’s was the Retrograde redux already shown. Halogen’s have been a series of experimental maps with altering geography to get interesting results.

I would love to see someone make a timeline base off of Mirrored Americas. I'll lay out a quick thesis I thought up.
15,000 BC: Mesolithic European Hunter-Gatherers cross the Aleutians/Bering Land Bridge to reach Alaska, proliferating throughout The Americans over the next 5,000 or so years. Further waves of migration from Europe and Northeast Asia follow over the next 15 millennia, forming a variety of races and cultures across The New World.
500 BC-500 AD: Several Greek and Roman expeditions to the north reach the Aleutian islands, as rumors of a vast land to the west have become commonplace. They go no further due to the rough seas and increasingly harsh climate.
800 AD - 1200 AD: Polynesian explorers reach South America. While the area they land in is arid, more habitable land is found further north, leading to Polynesian settlement in Northern Brazil. As in Melanesia, they mix with the natives to form new Polynesian-speaking, mixed race ethnic groups.
800 AD -1000 AD: Viking voyages go further than the Greeks and Romans had gone, conquering and settling the previously Celtic-speaking Aleutians and establishing colonies on the mainland. Their presence in Alaska gets less and less the further west you go, but individual expeditions go as far as Haida Gwaii.
1500 AD: The European Age of Exploration begins in earnest as the Spanish, knowing of a land to the west from the Romans and Vikings, send an expedition across the Atlantic to see if they could use it as a stopover point to get to the Far East. The expedition lands around Baja California, and the first Spanish settlements in The New World are established. You know what happens next.

In the last few days I've been thinking about how we could make a world where temperate climates were more abundant, I ended up thinking about a slightly different version of Jaredia, as you can see on this map the North Pole would be more or less in the State of Red Sea in Sudan, while the South Pole would be somewhere in French Polynesia, at the same time I moved the Americas to the South (West in OTL), making California much closer to Hawaii and the Antarctic Circle passing OTL west of Mexico. Also, as you can see, I added some lands from submerged mountain ranges like Zeelandia, Kerguelen, Rio Grande and Walvis Ridge
This means that most of the world would be located in the temperate zones of the globe,
Likewise, as you can see, I didn't consider rising sea levels, as I really don't know how things would be affected, what do you think? Would things be more or less like Jaredia? including Greenland as a peninsula, the much larger Caspian Sea and an existing Bering Bridge? what do you think?
Any idea where the cradle of humanity would end up here?

e.g. Ethiopia? Hmm, if we assume it has to be about the same conditions, Antarctica might be the most similar to our Ethiopia, being a tropical plateau. Though it would be quite isolated!

As for some of the things in your original post, it sort of seems like the icecap would be a bit smaller than Jaredia's since you're trading Arabia for larger parts of southern and western Africa.

The North Pole of this world is somewhere in Northern Ethiopia
 
Dunno if this fits the thread but here is a question i've been meaning to ask:

How would hurricanes (generated from what would've been the Atlantic ocean) work? Without any significant landmasses to stop them would they just swell up in size until they reach Asia?

Trying to work out a climate map for this and figured I might as well ask for advice here, since it started out as a simple Shiveria/Turnovia combination. Right now, this is just a rough sketch trying to work out the basics- grayish-purple is major mountain ranges, brown is deserts, green is tropical/tropical-adjacent forested areas, orangey-yellow is "I thought something climatologically interesting would be happening here when I was first putting the map together but had too bad a headache to work it out, and now I can't remember what my past self thought said interesting climate thing would be." Any feedback/criticism/suggestions/etc. on climate distribution is welcome.
May I use this map for its rivers?
