Are my skin and hair colors believable?

Migration happens Great effort, good to see a well-researched question with easily read visuals. Unfortunately, migration patterns tend to throw a spanner in the works, since people typically migrate ...

Are my skin and hair colors believable?

Assuming the planet shown is simply another version of the Earth, Then skin and hair colours would not necessarily be darkest around the equator, but in places with a combination of maximum sunlight ...

How would an extremely long winter affect an area?

If your kingdom has been in continual ice and snow for 153 years, the only life (wild or otherwise) lives close enough to the borders to get its food and water from outside, or is huddled around a ...

Could volcanic or geothermal activity alter the ambient temperature in a cold climate?

Agreeing with the content of JBH's answer, I think your best bet is to have a canyon into which a river of geothermally heated water flows. Hot and humid air would rise and condense on the walls, ...

Could volcanic or geothermal activity alter the ambient temperature in a cold climate?

Why do you want this to be science-based? The science-based answer is "no." Geothermal activity can change the ambient in a very (very) small volume of space, but not generally. This makes ...

Could volcanic or geothermal activity alter the ambient temperature in a cold climate?

Geothermal activity will not significantly warm the local climate, as the other answers have said. They've also pretty much covered the idea that since it's DnD it could just be magic, but since you'...

How would an extremely long winter affect an area?

Quick answer: here's what one year might do. This was 1816 and the winter followed the explosion of Mount Tambora. After earlier ice ages, we find mammoths that have been frozen to death with their ...

Can I have a supercontinent that is wet in its interior?

Please note that 1,200 mm of annual rain is twice the amount of rain received by the notoriously wet England. That's a lot of rain. While opinions are still unsettled about exactly how wet the Carnian ...

How plausible is my continent-wide rainforest?

It's not, you have created a mostly desert continent. You have done nearly everything possible to ensure as much desert as you can. Low axial tilt means smaller Hadley cells, which means mess moisture ...

Polar Desert. See link: https://en.wikipedia.org/wiki/Polar_desert As stated by the first poster the only life inside your kingdom aside from mosses and lichens on exposed (ice free) surfaces and in ...

How would an extremely long winter affect an area?

This depends wildly on the level of technology. If we assume a 21st level of technology, the transition would be hard and probably involve reliance on neighbours or famine, but the situation may ...

What would weather be like on a planet with only polar oceans?

We can make a reasonable guess at what the winds may do. The tropics of Earth are bounded by two rings of Hadley cell convective flow. Hot air rises at the equator and falls off at a latitude of about ...

What's the effect of increasing the Earth's rotation on climate?

If the speed increases slowly, the Coriolis effect will become pronounced and I think that will result in stronger storms and hurricanes. A more severe effect I can think of is that without any limit ...

Can I have a supercontinent that is wet in its interior?

Have a wet interior The main source of wetness for a continent is water. The sea, the oceans, rivers all that. So, to have a wet super continent, have it be wet. Have countless rivers and massive ...

All depends on whether you have a "butterfly effect on demand" magitech where you can very accurately forecast weather and influence it by subtle adjustments. Then you can do anything and ...

Using real examples, how long might it take for the species in a forest/jungle to respond to sudden climate change?

Im gonna assume that climate change is about the temperatures becoming hotter. Cause colder- we had that, we know how it went and it was not wetter, it was drier, cool and glaciers encroaching. So ...

How would an extremely long winter affect an area?

It would be quiet the achievement, but in theory, a small wandering tribe could prepare a "road" of resources in the summer/good years for the winter years. The tribe would then circle back, ...

How plausible is my continent-wide rainforest?

Make the center of the supercontinent a depression below sea level, with the edges of the elevated slightly to form a rain trap, and all the inland aquifers, rivers and streams going towards it. ...

How plausible is my continent-wide rainforest?

Rainforest can generate, at least at some scales, their own weather. See "A rainforest-initiated wet season onset over the southern Amazon" in PNAS. While this may not be able to solve ...

What should be characteristics of orbit of planet with sustainable climate if north is covered by ocean and southern by desert?

Now, I'm no climatologist or orbital mechanic, but I suspect that you don't actually need to reach as far as carefully planning orbital eccentricities and axials tilts and so on to get the effects you ...

Would the rain shadow effect cause this area to be a desert?

Size of the world has nothing to do with it. When winds carrying moisture cross high enough mountain ranges, they have a tendency to either dump their moisture or the moisture is converted to ice ...
