During the summer of 2022 Europe has had several heat waves. As described in 2022 European heat waves: Climatologists linked the extreme heat to the impact of climate change, and experts predict...
It might be that between year 0 to the industrial revolution (say 18th to common era), the Caspian sea significantly larger than it is today. If so, is there some graphical illustration as part of...
Say humans found a way to exponentially increase the capability of plants to grow. Is it possible for it to cause an environment that can cause oxygen toxicity in humans?
The year is 2100. While climate change has wrought serious damage to the biosphere, humanity has at last managed to become carbon neutral, and has even developed technology that can be used to redu...
An Earth mass terran planet is orbiting a sun-like star at 2AU. I understand the limit for CO2 greenhouse effects is 1.67AU for whatever reason (giving a conventional habitable zone limit), but per...
If it were possible to build a giant geodesic dome tens of miles in diameter, what effect would it have on nearby weather? If built in an arid climate like the Sahara or Australia, would it be li...
I'm attempting to flesh out the history to a sci-fi novel I'm currently writing, which is set in the future. Several hundred years prior to the beginning of the story, lack of resources lead to s...
My story has several key locations that I would like to ground in a real place in North America. It takes place 50-60 years in the future after 97% of humanity has been wiped out. I'm having a hell...
I'm thinking about a device (in a story I'm writing) that could control ocean currents, and I'm wondering how it could be weaponized. For example, if an ocean current was suddenly stopped, what mig...
I was imagining a sort of post-apocalyptic/collapse setting, where a few centuries of climate catastrophes brought on by climate change cause essentially your general end of the world as we know it...
What would happens if due to increased volume and reduced density, the global warming cause consistent loss into space of certain gases of atmosphere? What would we observe?
And if I wanted them to appear about 10 times the size of the sun and moon, would this be possible? Should they lie inside LEO or beyond it? I would like their orbit to be considerably closer than...
I have a story idea that involves a human attempt to halt and reverse global climate change. The idea is a simple one - a satellite that partially blocks out the sun. The satellite is located at th...
During much of the Late Pleistocene stage, the world's most widespread biome was the so-called "mammoth steppe" - a cold, dry grassland which spanned eastward all the way from Spain to Canada. It w...
It is the year 4056 (or probably later). The rocket with the last residents of Earth just took off, because global warming and pollution couldn't be stopped nor reverted and Earth became uninhabita...
Consider such a tidally locked planet: Many issues with tidally locked worlds have been discussed, but I'm not clear on how the water cycle for an otherwise Earth-like tidally locked world, woul...
I'm trying to find a plausible way to reduce global warming in a world past the tipping point. I recently read this article : https://www.sciencedaily.com/releases/2017/11/171127173225.htm. It su...
Trying to develop a fictional scenario with a 'believable' theory as to how a Nuclear War and resulting Nuclear Winter could turn into a millennial scale ice age. By 'believable', I mean that it p...
Supposing climate change continues at its current "worst case" projected rates, would we see a noticeable reduction in insects down the line? I am wondering if it makes sense to have a character wh...
With the rise of global warming and our leaders not seeming to do enough about it, expanding our ranges past the earth's ground seems like something we must do eventually. Everyone always points to...
The running theory is that if the Earth is hit by a sufficiently large meteor, that the impact would create an ice age from all the dust it would put into the atmosphere. While this has been histo...
In a comment to a recent question, it was pointed out that Biosphere II failed in part because too much CO2 was absorbed by the concrete, leaving insufficient oxygen in available CO2 to be released...
A Snowball Earth is a global condition (which may have occurred many times) in which the temperature everywhere on the surface was, for extended periods (up to tens of millions of years), below th...
My world is at the outer edge of the habitable zone. There is enough heat and geological activity to start life, but a snowball earth is looming and threatens to freeze it all. There is some spring...
My story takes place hundreds of years in the future after global warming has made life at the surface uninhabitable for most life forms. What's left of mankind survived because it became popular t...
The world is Earth, probably west coast of the USA, in the throes of severe climate disaster; major storms, earthquakes, droughts, fires and floods are the norm. I am looking for a way to suddenl...
I've studied a little about glacial melting and temperature changes in sea currents and worldwide. I couldn't find any definitive answer and since I'm no expert on this matter I'm a bit confused. ...
Suppose humans of the late 21st century or beyond began constructing a solar shield as a solution to climate change. Suppose for some reason (open to suggestions) they choose to build the shield in...
This is the first of possibly several posts about the following scenario, in which Earth's sea-level rises 2 km overnight, generating a world map looking like this: Question: What would be the c...
The second terrestrial planet orbiting the Sun is shrouded in greenhouse gases, the entire surface of Venus is always scorching hot due to the high concentration of atmospheric carbon dioxide which...
My story is based on a Glacial Climate setting or an Ice Age. However the transition is gradual and humanity was given some time to adapt. The transition began in our real-world technological equiv...
In 1815 Mount Tambora erupted throwing so much dust into the atmosphere that the year became known as "the year without a summer". *There were a few other mitigating factors but Tambora is thought ...
The first portal is placed at bottom-most point of the Mariana trench (the deepest part of any ocean, located in the western Pacific Ocean) and the second is placed in the Sahara desert in Africa a...
Using this handy dandy graph, I estimate that by the time climate change forces a response we will need to reverse 2° Celsius of heating. The method for temperature control is described in here ...
Suppose we have a world that saw a sudden collapse of civilization, not so violent that humans are suddenly struggling to survive but severe enough to cause humans to revert to a mix of city-state,...
Scenario: Say we have a massive release of greenhouse gases into Earth's atmosphere, however much for the ocean around Antarctica to get just warm enough for hurricanes to form during the summer (2...
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 ...
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...
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...
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...
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...
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...
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...
Lets suppose that Antarctica at some point lost most of its ice (due to global warming or some other plausible reason) and now most of its bedrock surface is exposed. Compared to other continents,...
The Idea is to move large amounts of water vapor high into the Troposphere, thereby blocking some of the sun's intensity. Factors that contribute the Earth's solar heat gain include reflectivity/e...
Sea levels are rising due to global warming. The Moon brings tides that also rise the sea level. If we destroyed the moon could this problem be solved? Would it have other consequences?
What would the weather conditions be like if earth was covered in a layer of clouds and pollution for 300+ years? there is still light in the day but it is minimal and the nights are pitch black. ...
Assume there is a giant steel (or any metal with good thermal conductivity coefficient) rod hanging from moon with its other end in atmosphere (say 5KM above sea level). 1.) Being the other end ...
