Ice Age Climate Climates and Geography While there are situations where shifting equator-ward (and colder climates shift downward with altitude too remember) may not be the precisely right answer, that is generally the case so long as you remember a few points colder weather may change currents that would bring different weather fronts which would change ...

Flame cloud deflagrations. The surface of your world is mostly reduced gases: hydrogen, water, maybe some ammonia, methane. On the surface the humidity and fog shields life from most solar radiation. In the higher atmosphere, energetic rays from your sun cause photodissociation of molecules. The main effect of this is to strip oxygen out of water, ...

[Handwavium explanation] Without Oxygen, you will have a hard time burning the hydrogen to create a fire. Since you do not mention the composition of atmosphere, one possible way you can achieve the Firestorm could be via a sudden outburst of oxygen in the atmosphere leading to the right conditions, which are otherwise absent. This could be due to ...

Under the given scenario, we all die. Some people die from swords. Most forms of complex life will be wiped out either by swords or starvation. You've just reduced everything to insects. Why? Because you just buried all the plant life under a whole bunch of swords, wiping out almost all agriculture. (Some trees might survive, but that's about it.) Even if ...

Unguided dumb kinetic projectiles have been used in wars gone past, such as the "Lazy Dog" used in Vietnam. You just shovel loads of them into the sky over the target, and let their kinetic energy take them through any cover (such as light roofing or tree canopy) and through any soft target underneath. To quote from the wiki page on kinetic bombardment, ...

I think the first thing people are going to invest on is better roofs, and then it's up for more portable versions of said roofs. I'd imagine the government putting up emergency shelters where people can hide in whenever these bladestorms happen. This may actually benefit us quite a bit since that's basically free metal raining from the sky. The cost of ...

Depends on the way the light gets "extinguished". The extreme scenarios: absorption - the stuff absorbs the light and "store" the entire energy - think "black body". Gets hotter (the absorbed energy is converted lower frequency spectrum + increased thermal agitation). Cannot get hotter than the source of the radiation (the planet's star) without violating ...

FOG1 Should FOG1 look like Venus, it is because it will in some aspects be similar to it and because this is an image of Venus. :) FOG1 is a predomenetly metallic (read 90%+) super-earth orbiting a long lived, dim K-Type star. Its planetary attributes are: $$M = 7,5 Me$$ $$R = 1,3871 Re$$ $$gravity = 3,898 G (38,228 m/s^2)$$ $$Vescape = 26 km/s$$ Its ...

Frame Challenge As pointed out in the comments, free oxygen or free hydrogen cannot stably exist in an atmosphere dominated by the other gas. Something less reactive, however, has possibilities. Enter methane. The Fire Swamps Due to distance from the solar system's primary star and a thick, water-rich atmosphere, temperatures on Flareworld are ...

Hydrogen will burn at only 4% concentration, but you will need 18-60% concentration for an explosion. However, you will not reach this limit unless your creatures are in an enclosed space. Hydrogen is much lighter than air and will simply float away before you get to this level. With storms raging, the excess hydrogen may increase the flammability of ...

Note that the Sahare wasn't always a desert. It switches climate between lush grasslands and inhospitable desert and did so the last time maybe as recently as 5500 years ago. This is part of the climate veriation due to the Milankovitch cycles, the same mechanism responsible for the ice ages. Some of the lakes actually exited back then due to the higher ...

If I understand you correctly, you are asking if the Sahara region would still be a desert in your proposed scenario. The short answer is probably not. Look at the borthern region of South America. Similar equatorial position, but the presence of abundant water instead creates a dense jungle, which is also true of central and southern Africa (minus the ...
