The good news is that it will never get to that point. Venus is a different planet with a different makeup and history.
The bad news, it doesn’t have to get nearly that bad to be bad for us and the rest of existing life. Not even close. Just a few degrees more, and we’re doing really well in getting there.
I’ve heard of the runaway greenhouse gas effect. Is there a limit to that?
The limit is our distance from the Sun. After a certain point the greenhouse gasses can’t make up for the fact that we just get less radiation than Venus does. The maximum potential I’ve seen is 10°C - almost all life would go extinct and we’d have to live on the tropical Antarctic archipelago, but not Venus.
Everything find equilibrium eventually. I’m sure any limits for a runaway situation depend on a lot of factors, but their ceilings are all far above anything we could tolerate. Runaway doesn’t mean there’s no point to level out, only that at the time it’s not controllable and escalating fast.
The last “runaway” situation the Earth had was called the Paleocene–Eocene Thermal Maximum (PETM) 56 million years ago and globally had a 5-8 degree Celsius rise over thousands of years. That might be a good example of a natural situation and its limits. Keep in mind the differences in rate, we’re increasing the global temperature faster than the PETM (or anything we’ve found in geological history) so we don’t know how that faster rate will act in determining a peak. There’s theories of pushing the Earth into a hothouse world that would have its own equilibrium that is far hotter than we can survive.
Bruh, just realized terraforming starts with terra and that’s why it’s what it’s called
The term translates horribly into Finnish: “maankaltaistaminen”. “To make like Earth/ground/dirt” and “make like” as in “type”, not “form”.
So it could be like “earthlikening” instead of “terraforming”.
Which makes me think of this Wikipedia that’s written in the way they imagine English could’ve evolved if it wasn’t influenced by Latin.
https://anglish.fandom.com/wiki/Main_leaf
for instance their article on maths starts with:
Telcraft (scorelore, rimecraft or reckonlore) (English: Mathematics) is the smeying of scorings, or the recking of begrips such as score, room, shift, and forebuilding. Benjamin Peirce called it “the cunning which draws needful outcomes”.
Through foredeeming and wordlock mulling, scorelore arose from notching, reckoning, deeming, and the learning of sheathes and shapes.
Knowledge and note of fern scorelore have always been a spanning and a needful lifetool, as can be witnessed from orshafts of Egypt, Bearithland, Indland, China and Frodland. Furthermore, the Ishango bone is more than 20 thousand years old.
Titillating, isn’t it?
Same lol
But think of the shareholders!!
Much more likely the whole earth turns into a desert, no?
Earth’s surface is 2/3rds water and that’s not changing.
But intense heat means more storms with stronger winds and heavier rain. Imagine a Cat 5 hitting the coast every year.
No, that would be mercuryforming Earth. Earth will still have an atmosphere and rainfall, though it may no longer be livable for humans.
The acid rain is going be be so slimming.
I, for one, would like to give a shout-out to my dog, magnetosphere!
Holla!
The magnetosphere has been weakening in strength due to the ongoing pole shift over the past 30 years, which will peak in the 2040s when the poles will fully shift. I pray there will be no solar flares in the direction of earth during this event, otherwise most of unshielded electric equipment will get fried, including energy infrastructure.
No way. Is that really happening? The magnetic poles are flipping the 2040s? How often does that happen? Old compasses won’t be correct? Will it affect anything else (Aurora Borealis?, etc?)
I’m plumb flummoxed.
Aurora Borealis will be more visible because of the weakened magnetosphere. I don’t know what implications this will have on the world in practice.

This guy Earth’s
Interesting name for a dog, not gonna lie
Maggy for short, I’m sure of it.
Venusforming earth is a lot like terraforming mars, it’s just hard to reach. If 200 years ago we were able to easily reach mars, we would have fucked up that too
The feminism-oil complex
Musk is desperately trying to make “women come from Venus, men from Mars” reality
Earth has been around for 4.5 million years. Humans have only been around for 300,000 years approximately. With only a few hundred years of the industrial age.
Would a few hundred years really cause an extinction event?
That’s interesting to think about… Perhaps it’ll take a few hundreds/thousand years to fix. If it can be fixed… Or we get hit by an asteroid first…
Between cutting down all of the trees and other pollutants, like these so called environmentalists flying around in their own private jets, it’ll be fun for a while.
Either the humans will die off due to global warming/runaway greenhouse effect before interstellar travel is achieved, or the humans will die off due to the suns transformation into a red giant before interstellar travel is achieved.
IDK. Either way, we won’t be here for long. But the earth will be long after us.
Will technology save the human race beyond the two inevitable events? Probably not.
I assume that the red giant sun engulfing the earth will produce enough drag that earth loses momentum and falls into the sun permanently. We’ll still be gone by then, but noting is forever, even the earth itself.
Yes , you’re right. The red giant will consume the Earth.
We won’t be alive if there’s a mass Exodus from earth, but is that even possible?
Probably not
Venus does have a lot of valuable materials, this could be a good thing.
I can’t wait to see the shareholder value.
I’d rather live somewhere habitable than somewhere with “valuable materials”.
We’re just trying to make it more hospitable to women. They’re from Venus, after all.
The government never built a weather machine. But the oil companies built a carbon machine that’s doing a fantastic job changing the weather, and they knew it 50 years ago.
Not one single government cares so much about it tho.
Higher temperatures will free up soil for agriculture in upper and lower latitudes. With luck, population size will keep increasing then for those countries and also quality of life
Coastal cities can fight it, at least some to some degree.
If we get fusion between our lifetimes, things are going to get even better
Not one single government cares so much about it tho.
Way to generalise, bro. There are some low lying island states that are going to disappear under the rising sea levels. I think they are taking it pretty seriously.
Don’t bullshit please.
If people and government really cared that much about it, we all would be living in a totalitarian planetary government, controlling by the milligram every expense that is not calorically viable to post culling population of billions.
Either or they ALL would be pumping up so much nuclear centrals that we be drowning on the almost free energy
Either that, or they ALL would be pushing for the creation and implementation of a totally viable lunar base to construct a full orbital cache of microwave solar emitters, with the accompanying swarm of orbital mirrors to reduce the sun’s impact on the atmosphere
We see advance in neither of those
So yeah who’s bullshitting who. I know they don’t care and don’t have to pretend like they do
Your pathological need to believe a blatant lie due to your own powerlessness? That’s all on you
Meth. Not even once.
Talking from experience I gather. Don’t worry, we noticed
They say do what you know best.
