That crashes the food chain, both on the land and in the sea. Very few can live in perpetual dusk conditions. You'd have immediate attrition of most photosynthesizers. Mushrooms don't need much light at all, so you'd probably see lots more of those - and with less competition, they'd probably grow larger. I live in an area classified as taiga, and since it's the dead of winter right now, there's simply nothing growing at all.Īn alternate take on plants is that you'd see far less in the way of chlorophyll. Or, if you have a little bit more light than that, it'll look like taiga areas - but that's not a great comparison, because life in the tiaga depends on the growing season to function. There would be no trees, because there's no enough energy for them to grow, and most plants would stay pretty small. Also remember that less extreme weather means less erosion, which means larger mountains.Īs far as plants go, look to what grows up in the tundra areas of our world - small shrubs, grasses, mosses, and lichen. I'm assuming here that there's enough light to keep your world above the freezing point. A low amount of weather means that the interiors of continents would be deserts. and you wouldn't have a wet or dry season or anything like that. With no differences in temperature, you'd see much less in the way of tornadoes, hurricanes, etc. The main driver of weather on Earth is the warming and cooling of air and water. It depends on how much light there actually is.Īssuming relatively static position of whatever's giving you the dim light, there would be no way for you to have any seasons, which means that there'd be no annual migration patterns, because there wouldn't really be any year at all. Not tidally locked, just the same amount of solar heat and light all over the world, all the time. Perpetual dusk: everywhere, all the time.For sake of argument let's say no advanced civilization. If I wasn't clear enough with the parameters, please use the following: I don't want to quell discussion, but I urge you to skip this part and speculate on the impact to plants, animals, and the weather. I'm hoping I can get some more direction with your help.ĮDIT: I appreciate all your responses, but I see a lot of people getting caught up on the "how". I'm wondering what kind of impact this would have, if the Earth (or an Earth-like world) suddenly switched from a diurnal (day/night) cycle, to a state of perpetual dusk-like conditions (low light, low solar energy).Īpparently I need to do "more research" before I can go back to the "professionals" at AskScienceDiscussion, but I'm not even sure where to begin. I think they just don't want to think too hard :P That's where you guys come in! Related SubredditsĪskScience didn't like this question.too much speculation they said.
