How can I arrange for a planet to have a much greater temperature range between the poles and the equator without it being tidally locked? Edit: By "much greater" I mean the temperature at the pol...
An ancient human like civilization exists on a planet like our own but warmer, with more deserts and smaller oceans. Climate change is forcing the daytime temperature slowly upwards. What measures ...
I am designing a fantasy setting for pen-and-paper role-playing purposes. I have decided that a continent be situated right on a Pole of some imaginary planet with axial tilt comparable to Earth. M...
So, a neat thing, depending on how you look at it, about greenhouse gases is that while it's causing a raise in temperature near the surface it actually makes the upper parts of the atmosphere decr...
Okay so there's a project I've been thinking about for a long time wherein humans colonise a world where the climate appears warm and benign only to discover that the local climate oscillates from ...
I created a fantasy map a while back, but only recently have I realised it may have a major problem. There is next to no land at the equator although some land between 0-30 degrees. The vast majori...
This planet I am proposing is approximately half the size and mass of earth and has two moons. The moons are respectively 1/8th and 1/10th of the size of the planet.The moons orbit the planet at di...
I'm trying to create a world that has a equator-like climate in the north pole and the same arctic south pole. I have done some research already but there are a lot of things I don't know but the h...
I live in Cape Town, South Africa where it is a very real possibility that not a single drop of water will be left in our dams come March 2018. THIS is a news article that suggests that at a gover...
I was trying to make an interesting moon of a gas giant similar to Jupiter with a liquid ocean of water. The moon orbits in the equivalent orbital space of Io and is about twice the size of Mars. T...
I created this climate map based on the Koppen Climate Classification map. In this scenario Australia is moved 10 degrees of latitude further south and the Lake Eyre basin is filled (shown in map...
I need to create a world with some very high plateaus and some very deep depressions. The sides of these structures should be very steep and unclimbable. They need to provide an obstacle sufficient...
Let us take an earthlike planet. Approximately same radius, atmosphere and climate. Now let us create an approximately circular, paleovolcanic mountain approximately 30 kilometers in height and 15...
Assuming we have a world at the same stage in global warming as the Earth, with all other properties similar (population, carbon emissions, general climate, orbit, etc.) How long will it be until t...
Could a world similar to that envisioned in the Mars of Edgar Rice Burroughs / H G exist? And if so would canals be a practical way to make the planet habitable over the long term? For current pu...
A little while back, I went to see Valerian and the City of a Thousand Planets (honestly unsure of what reaction this is going to get), and there was a particular scene that showed a desert planet'...
I have the below snippet describing a planet in a (hard) sci-fi setting. This harsh planet has some human settlers, who can survive the climate in light weight environmental suits. The planet i...
Let's assume we have an otherwise Earth-like planet orbiting a star just like our own. Our planet has an axial tilt of 0 degrees, meaning its axis is perpendicular to its orbital plane. Could this...
On a certain planet, the sole continent of land is a large circumspecting ring about the equatorial regions, with a width averaging 500 miles. Rotational north and south are entirely pelagic. Var...
So it turns out that all of the people claiming global cooling were right. Our earth is heading towards freezing temperatures, and we need to raise our earth's temperature by 1°C as fast as possi...
I've heard that the atmospheric pressure on venus is 90 times that of earth, but I don't know the melting point of $SiO_2$ at 90 atm nor at what temperature its vapor pressure hits 90 atm. Basicall...
I need maps of climates and prevailing winds for my desert-dominant world. It has one continent stretching in a band around the tropics and into the subtropics, making up about half the planet's su...
I want the temperature of the earth's poles to be higher so that they have a temperate European climate with yearly temperatures averaging 15-20 degrees Celsius. What will the climate of the rest ...
This is another question about PommeDeTerra: Thanks to the orientation and position of the planet, PommeDeTerra has a habitable island with a temperate climate at it's south pole that looks a l...
I think of a world of islands floating in the sky. The planet basically is (was) our Earth. For some reason all that is left is a small ball covered nearly completely with water. Pieces of the shat...
For simplicity assume hypothetically we make multiple copies of earth: XS, S, M, L, XL. The only difference between them is their size (radius), everything else is the same. S is half the size of...
Has anybody made any serious calculations of what the climates on Earth would be if our planet had a larger axial tilt? The most interesting are the cases of 45 and 90 degrees.
My question is : Is it possible to have a hot desert planet with no significant vegetation with the surface mainly covered with liquid water? Normally, we should expect to have rain overland beca...
This world takes place in the remains of the Eastern United States, devastated by 3000 years of neglect and climate change. The Mississipi river is pretty much a gulf now, which has caused everythi...
Subangea is a giantic cave that stretches below the surface through endless cavities. From oil oceans to volcanic sinkholes and even upside-down forests, the environment is ever changing from one c...
Epic fantasies typically depict northern areas as cold and southern areas as relatively warm. Is this just to play into reader expectations since that's the way it is on Earth, or is there a scient...
Okay, so imagine a situation where most of earth's atmosphere is lost, the pressure at sea level is somewhere around 0.3 atm. If it matters, let's say that this is the result of the gradual escape ...
So there's a planet that is used as a farming world (food) for its system. This planet has a single, Mediterranean sea-sized ocean on it and lacks any other major surface oceans (he hasn't excluded...
The ozone layer depleted beyond reasonable levels and life on the surface has become impossible and life migrated underground in giant caves connected together by tunnels. Some of those caves have...
In the Chronicles of the Riddick there was planet Crematoria. Temperature during the day there was 372°C and during night −182°C. There is not much information about about this planet avaiable. ...
If an island in a sub-tropical region were to be unreachable because of natural phenomena, what could those phenomena be? The people trying to reach said island have 17th century seafaring technol...
This post: How to increase air density on a planet? explains most of the problems I have been having, and fixes them. My current problem is as follows: On a planet with an air composed of (roughly)...
The area of the earth covered by desert is more than 20%. (Sites range from 20-33%, I don't know why the wide range). With technology close to providing zero cost solar (not free, but declining e...
This is specifically about the climate, and where on the planet it would be mildest. Imagine Earth, rotating at the usual distance from the sun. Except, it is tidally locked to the sun; a so-calle...
It's 2070, global warming is a terrifying reality. Coastal cities such as New York and Shanghai has already fallen to rising sea levels and extreme weather. In an effort to stem and perhaps counter...
Relating to this question: Ensuring an endless war, and an endless stalemate In a planet such as our Earth, what climate conditions and/or atmospheric changes would be required for the formation a...
2017, flying islands just appeared in the sky. Different places in the world, different sizes. The biggest one is about the size of the Corsica french island. They have similar ecosystem than Eart...
In film "The Day After Tomorrow", a giant snowstorm seizes the Earth for days and freezes nearly everything. What I want to know is, that is this possible in current Earth climate and geology? It d...
Would it be possible for a single motorcycle to harm a world so much that it would cause significant change? Conditions: Unlimited Amount Of Time The Planet Is Not Earth (No other cars, factory...
I'm not talking a single-biome sand-world. Of course I want the classic large sand seas, but I also want steppes, mesas and buttes, floodplains, salt pans, hamadas, and canyons, both hot and not so...
Assuming it just spins at the same rate, the other way. Axial tilt is the same, year length is the same. Perhaps winds and ocean currents? What would the effect be on geography? Would deserts or r...
The sun is perfectly fine, but for generations, not a single human has seen sunlight. Earth is completely covered in black fog, reaching high up into the atmosphere, so that not even skyscrapers ca...
Climate is not my priority because I prefer to develop the culture and the languages. However, climate has a strong influence in the culture, so I need to know the basics. So, I have a country loc...
