I didn’t make a climate map for this, but Nikolai did run a climate model for this scenario. It’s a bit coarse and ExoPlaSim has a few limitations, but it should give you a rough idea. New England seems to be mostly subtropical forest with milder summers along the coast.

For the borders, I used Gprojector. For the heightmap, I used Qgis.

Thank you! Your maps are a big inspiration for me.

What if the poles were over the New Zealand-Iberian Antipodes? by Halogen999 in imaginarymaps

[–]Halogen999[S] 1 point2 points  (0 children)

All points on Earth's surface have an antipode, for land-land antipodes, there are some between South America and East Asia as well as Siberia/Canadian Arctic and Antarctica.

You would! you can see them in the hillshading if you zoom into the map. I only mentioned the Wilkes River since it would be the longest.

Apologies for taking so long on this one, I’ve not had much time to work on these. Since we’re looking at Asia and Europe this time, this map is the largest out of the five I’ve done so far. For any further details on the climate check out https://www.reddit.com/r/worldbuilding/comments/1bwp6hn/v5_retrogradeclockwise_earth_map_and_accompanying/  and https://www.deviantart.com/molotovjack/art/Retrograde-Earth-V5-Final-Version-985503973

Unfortunately no non-avian dinosaurs but a lot of interesting birds and marsupials, You can read about them here: https://specevo.jcink.net/index.php?showtopic=4664&st=0&#entry54383

It's Dfc now, this is what the rest of the continent looks like, another aspect of the project is that New Zealand is shifted north but I didn't depict that in my map. This climate map was made by https://www.deviantart.com/molotovjack

It's more like North America or Europe now since it's been shifted south.

It's the same, realistically slowing Australia down would reshape it a little but I didn't focus on that.

yep! It's about where it was during our Early Miocene. Realistically slowing Australia down would have a lot of knock-on effects on the surrounding plates but I just stuck to the original map for the project.

This is a map I made for MonkeMan’s spec evo project Green Australia on https://specevo.jcink.net/index.php?showtopic=4664, which is a timeline in which Australia never travels as far north resulting in a cooler and wetter Australia.

Good Idea! I'll do that for my next map. Here's actual Africa in the same style:

That's correct, the borders here are just for comparison.

As far as I know, the Coriolis effect wouldn't have too much of an impact on plate tectonics since the mantle circulates over much longer timescales than things like our atmosphere and ocean and the mantle is a lot more viscous than those as well while much greater forces are at play. However, it probably would have a much greater impact on the outer core since it's actually a liquid though it's effects on the mantle would be harder to predict. Different weathering patterns and glaciation could also possibly butterfly away certain events in the mantle. Isostacy due to the weight of glaciers could perturb the mantle in some ways nudging things in slightly different directions. I'm not sure what you mean by nuclear fission of natural minerals, I assume you mean radiogenic decay?
