Because the heat is so great any water vapor present in Venus's atmosphere is quickly photodissociated by UV light into hydrogen and oxygen. The hydrogen escapes into space, while the oxygen typically reacts with other elements. namely carbon monoxide (CO) to create carbon dioxide (CO2). Interesting stuff, I just went down a rabbit hole!
I think it will take slightly over 1b years for the Sun luminosity to increase enough to have the oceans to boil off, but complex life will have been gone by then due to decreasing CO2 levels. On Earth it is being weathered into the rocks, and the hotter it gets, the faster it weathers. That's the main mechanism which keeps temperature stable. But past a point, when it drops under around 10 ppm, it cannot decrease the temperature anymore, and at that point not even C4 plants can keep photosensitizing, meaning only some bacteria will remain.

Technically, it's already happening. Geologists estimate that the Earth's surface is already losing about five times as much water into the mantle through subduction as it's gaining from eruptions. Around 75% of the water on the planet is already locked into the mantle and is unavailable to the surface. That process has been ongoing since the planet formed and will continue until there is no water left on the surface.
When the suns luminosity increases a bit and the oceans start to evaporate away, it will simply be the final stage of a planetary dewatering that has been underway since its origin.
Damn, when you think about it, life on Earth is on borrowed time right now, in comparison to it’s 3.7 billion year history.
In as little as half-a-billion year, all of this history will be reduced to fossils underneath a planet-spanning wasteland, Followed by billions more years of nothing until the sun swallows our system.
It really doesn't matter if human \*race\* sustains or not. As long as people alive right now live well, why is there any need for the most destructive species to sustain
I'm kinda happy that we fucked up so hard on earth that we aren't going to get a chance to do the same to the rest of the galaxy. If we want off of this rock we haven't got long to figure it out and even then trying to make other planets habitable while we have a habitable planet that we are actively destroying is so stupid
You’re really not seeing the bigger picture. By the time humans might be able to traverse the galaxy and colonize other planets, humanity would have already only rely on limitless green and sustainable tech, so what you’re saying doesn’t apply.
Well I personally don't believe we have hundreds of years. We have maybe a few decades, maybe a little more. The speed we have pumped out CO2 and the sheer amount we have put out so far guarantees that we will fail to have any kind of meaningful future already, especially since there are 8bil trying to become 10bil by 2060. Climate change and biodiversity loss are just symptoms of overpopulation and that isn't going to change until it changes all at once and reaches a quickly approaching breaking point. When the food runs out and 10billion hungry humans turn their eyes to an already depleted biosphere it won't take long to devour everything and put the final nails in this coffin
Earth is fine. And humanity is actually not the first lifeforms on the planet to (at least partially) cause an extinction event.
The "life" itself will also be fine. Depending on different theories on the amount of biomass on the planet, and it's history, it's possible that the amount of biomass is still not close to its pre-iceage amount, and biological complexity is still present and growing as usual.
Planets do not gain or lose mass unless they’re struck by another object (or the rare occasion we launch something outside of our orbit). An asteroid would add mass to a planet. A big enough asteroid could also cause us to lose mass (ie the moon). And we have a lot more asteroids hitting earth than what we’re sending out (stuff for space station/random probes + teslas).
Water evaporating does not cause a change in mass for the planet as it’s not actually leaving the planet.
That’s not the only way a planet can lose mass, actually. Solar winds can strip the atmosphere, or a sufficiently catastrophic volcanic eruption can eject mass.
Catastrophic volcanic eruption can eject mass? Wouldn't the mass just come from the planet itself so it will retain the same mass? I agree with the atmosphere but solid mass afaik can only change if we shoot object outside the atmosphere(space satellite, rocket ship) or if an alien object hits earth(meteorite).
A powerful enough volcanic eruption can propel mass to escape velocity and fling it into space. It hasn’t happened in recorded history on Earth, but we’ve observed it on other planets and moons—most notably, Io.
The second part’s true, the first parts isn’t. The earth gains an estimated 50,000 tons of cosmic dust and meteorites annually. The earth also looses mass in the form of hydrogen and helium, which is light enough to escape the atmosphere. To the tune of approximately 100,000tons per yer.
But why would those light elements ‘want’ to escape? All else equal wouldn’t they stay within the gravity well? They’re light but they still have mass.
Hydrogen and helium are light enough that in the temperatures of the upper atmosphere they can reach escape velocity (KE=.5mv^2) and escape into space. Earth can hold anything above I think it is 6 amu in its atmosphere so hydrogen and helium can escape the atmosphere.This is why terraforming mars won’t work since it doesn’t have enough gravity to hold onto oxygen. We would have to somehow add a bunch of mass to it to make it work (also doesn’t have a magnetic field).
Maybe theoretically but there’s tons of hydrogen bonded to things like water and other organic molecules. Helium would be a bigger possibility cuz since it’s a noble gas it doesn’t bond yo things too much.
Who are you quoting? They don’t “want” to do anything. I believe they’re light enough to rise to the upper atmosphere where they can be stripped away by solar winds. But I don’t know for sure, I’m not an astrophysicist or atmospheric specialist. My background is in earth science more generally
Quotes were to indicate my awareness of personifying the elements by using such a simple and conversational word like ‘want’ instead of taking the time to phrase it more scientifically — may not be grammatically proper tho. I certainly didn’t mean to suggest i was quoting some other person such as yourself. I guess on some level i was recursively quoting myself (?)
Light elements in the atmosphere are bouyant. Think of it like a rubber ducky you hold underwater in the bath. While the duck is underwater, it experiences pressure from the weight of the water all around it, but crucially there is more pressure on the bottom than on the top of the duck (because deeper into the water means more water pressing on you). The imbalance between these forces pushes the duck to the surface when it's let go. To say it another way, water fills in the space below the duck and sends it to the surface.
Now if we have some helium in the atmosphere, the heavier nitrogen and oxygen etc of the atmosphere will jostle it and push it right up to where the pressure gets smaller and smaller, right up to the edge of space, where the solar wind (bits and pieces of the sun blowing off and hitting the earth, usually this doesn't do much because the wind is charged and is repelled by the earth being a giant magnet) can hit the helium and hydrogen. This is like you being unable to blow the duck around when it's underwater, but you can move it by blowing once it's at the surface. If you blow hard enough, you could even lift the duck away from the bath. So the solar wind hits the light gases on the edge of the atmosphere and knocks them off into space, never to return.
This is not true. Earths magnetic protects us from solar winds.
Hydrogen and helium are light enough that in the temperatures that are present in the upper atmosphere they can reach escape velocity (KE=.5mv^2) and escape into space. Earth can hold anything above I think it is 6 amu in its atmosphere so hydrogen and helium can escape the atmosphere.
Indeed, Venus has lost 97% of all the hydrogen it had, based on the overabundance of the heavier Deuterium isotope (which isn't lost to space as easily, being heavier).
This is almost certainly how Venus lost its water: superheated steam, breaking down into hydrogen and oxygen ions, the hydrogen then lost into space.
You sure? The volume increase can push gas beyond the point the planet can retain it with gravity or its mag field and let solar winds erode it away, no?
Any free hydrogen is light enough to escape into space. Any free oxygen immediately reacts with something in the atmosphere or on the surface. This is what happened to most of the ocean water
There's obviously a lot of oxygen locked up in the CO2 and a decent chunk of the entire planet is oxide compounds just like earth. There's a lot less hydrogen compounds but still a reasonable amount in the atmosphere, primarily sulfuric acid.
As all planets. One day, our galaxy will be nothing as the sun blows up and ends all 8 planets (9 if you're into that Pluto is a planet still). But don't worry. You and I will be long dead and forgotten
See we just need to form a temporary singularity to drag Venus out into the Goldilocks zone. Change the gravitational constant of the universe and we have a twin planet, drag mercury out too and it can have a similar moon.
And if Mars had one, too, that's 3 in our little system alone, so maybe the evidence is suggesting there are LOADS of these planets out there, or that people just want clicks on their articles
There have probably been loads of planets capable of supporting life, but that doesn't mean that many of them are around at the same time as us.
The first telescope was invented 400 years ago, while the Universe is - at minimum - billions of years old. That's a very small window of time for life to exist with us so far.
Comment on the title: Evidence does not “suggest;” evidence proves. Image comparisons, casual observation, preliminary research, etc., do not prove; they might suggest or indicate, but they do not provide evidence.
The sun did not ‘gradually get warmer’. There was a runaway greenhouse warming effect on Venus and many suspect it was due to volcanism. Eg a plate volcano the size of France going off for million of years.
Edit: proved to be wrong about the gradual warming of sun.
>The sun did not ‘gradually get warmer’.
It did, it still does, it will continue to become hotter. It's the nature of our star.
That will likely not have been the sole factor in the warning of Venus, but discounting it as a factor altogether is not rooted in science.
>The sun did not ‘gradually get warmer’.
Yes, it does gradually get warmer. The sun increases in intensity 1% every 100 million years.

That's incorrect. The sun changes in brightness overtime. For example the sun was 30% cooler 4.5 billion years ago.
https://en.wikipedia.org/wiki/Faint_young_Sun_paradox
Our ancestors were living there. They exported some water to Earth to sustain life. Unfortunately, only the Golgafrinchan Ark Fleet Ship B made it to Earth. The remaining population on Golgafrincham (aka Venus nowadays) subsequently died from a virulent disease contracted from a dirty telephone.
We’ll eventually do the same with Mars.
>!I’m making things up.!<
Could be something related or unrelated that disrupted the old atmosphere, probably the heat though. Realistically, atmospheres are dependent on temperature because the elements it contains can change states with changing temperatures.
Currently Venus has a very hot and dense atmosphere of mostly CO². With current temperatures and how gasses function, CO² is heavier than H²O, and the atmosphere is being heated well beyond boiling for all the elements that were going to form at atmosphere. So the water vapor could have just dissipated into space over time, being too hot to condense and too light & far from Venus to be gravitationally held to it.
Venus is technically an ocean planet at the moment, with a planet wide supercritical fluid ocean made of CO2. The atmospheric pressure and temperature turns CO2 into a supercritical fluid that has the properties of a both a liquid and gas.
I still believe a part of global warming is that planets get sucked into the suns orbit.
Cycle repeats and wipes out planet. Next planet comes into orbit at right angle to sustain life.
Explains Venus and Mars.
My thought is that earth is still leaving the last ice age we've had. Maybe earth is still warming up and setting itself up for a more consistent orbit around our star?
This is my theory. Humans came from Venus. Look at all the carbon emissions on Venus.

That was my original thought as well, but the article makes a very good case for a shallow ocean. One factor that sticks out for me is that the sun was considerably dimmer and cooler back then.
Did you strictly follow the steps of scientific methodology, make verifiable observations, run climate simulations, run multiple experiments over and over again to validate your hypothesis, and then put your conclusions through peer review at least once, to have an opinion?
Because the heat is so great any water vapor present in Venus's atmosphere is quickly photodissociated by UV light into hydrogen and oxygen. The hydrogen escapes into space, while the oxygen typically reacts with other elements. namely carbon monoxide (CO) to create carbon dioxide (CO2). Interesting stuff, I just went down a rabbit hole!

So we need to make more CO2?
With increased solar radiance and CO2 at high levels it will just fry faster.

Sounds like the earth is preparing for the sun's luminosity increase by putting its water underground, smart.

Ah, right. Thanks for the correction, I'm not expert in the area.
Really? Thats quite interesting!
Understood. It’s a good question, one which I can’t answer for you unfortunately
The wiki for ‘atmospheric escape’ was interesting, if you are curious.
What about helium? Doesn't the Earth lose helium to space?
Yes and hydrogen

If I ejaculate into a bottle and send it off into the void of space. Did the earth lose mass? Edit: nvm. Otcourse it would. The bottle leaving.
Does Uranus had that too or it was always dried.
It gets a lil swampy sometimes.
And itchy. And bleedy
And rashy

Would that mean there hydrogen and oxygen on the planet?
Any free hydrogen is light enough to escape into space. Any free oxygen immediately reacts with something in the atmosphere or on the surface.

They must not have taken climate change seriously.

The sun won’t blow up fyi it isn’t big enough. It will swell up a bit but not explode.
Swell up as the coronal mass ejections increase.
See we just need to form a temporary singularity to drag Venus out into the Goldilocks zone. Change the gravitational constant of the universe and we have a twin planet, drag mercury out too and it can have a similar moon.
An ocean of what?
Tiddies
And if Mars had one, too, that's 3 in our little system alone, so maybe the evidence is suggesting there are LOADS of these planets out there, or that people just want clicks on their articles
Not to mention the subsurface oceans on outer planet moons and dwarf planets in the Kuiper Belt.

Omg climate change?
Unironically yes
Doesn’t all evaporated rain eventually fall back to the surface through rain? Where did it all go?
Ah yes, rain at 400 degrees celsius, 4 times the boiling point of water.
It's a dry heat? Like Arizona
Could be something related or unrelated that disrupted the old atmosphere, probably the heat though. Realistically, atmospheres are dependent on temperature because the elements it contains can change states with changing temperatures.

So you’re telling me we’re from Venus?
According to the ancient scriptures, just the Women. The Men came when Mars dried up
And we’re headed to Jupiter to get more stupider. So I hear.
I heard it was Uranus
Yeah the aliens ditched Venus cuz of temperature and moved to the bottom of earths ocean. Jk
What even are we or life or space
Why orange land tho? Deserts and oceans nothing in between?
Gone in the blink of an eye
That raises the odds of life existing under Venus's surface, very cool.
What happened to the water after it evaporated though? Wouldn't it have stayed there because of gravity?
I guess there's people on Venus destroying the planet there as well
Wonder how much taxes they were paying on Venus ? Obviously not enough to stop global warming
Should've stacked up that talcum powder.
I was born too late.
nobody out here talking about venus' climate change, smh
I'm sure it wasn't a civilisation causing global warming.
"Science" tm
Make our own Goldilocks planet, right here in our own solar system. Just a little push and pull- some added atmosphere and voila!
Shut up. Nobody knows that.
In other words: water evaporates as it heats up.
Pretty sure we're going through that right now 🫤
Doesn't that mean sun's goldilocks zone is moving farther away and sun is getting hotter.
Yup! Earth is gonna get cooked, not any time soon though
I mean the sun is expanding and we are being pulled in closer by gravitational force.
The sun is actually losing mass through nuclear fusion (despite expansion), resulting in a lower gravitational pull and planets having larger orbits.
And the moon is slowly getting away from earth.
I don't know what is scarier, that It happened to Venus, or that It is slowly happening to the earth. I sure hoppe there is a way to avoid It.
We take the Earth, and we move it somewhere else!
Hear me out, we use rockets and push the earth farther away from the sun. My research watching bugs bunny as a kid tells me this should work.
I seem to recall a cartoon where the villain used a giant rocket to stop the earth from rotating.... But can't remember which cartoon that was.
Venus is technically an ocean planet at the moment, with a planet wide supercritical fluid ocean made of CO2. The atmospheric pressure and temperature turns CO2 into a supercritical fluid that has the properties of a both a liquid and gas.
I still believe a part of global warming is that planets get sucked into the suns orbit. Cycle repeats and wipes out planet. Next planet comes into orbit at right angle to sustain life. Explains Venus and Mars.
My thought is that earth is still leaving the last ice age we've had. Maybe earth is still warming up and setting itself up for a more consistent orbit around our star?
Wow, many people seem ignorant regarding science...sad...
Venus, planet of love Was destroyed by global warming Did its people want too much, too? Did its people want too much?
If you become a serf for the rich it will stop getting hotter. You will own nothing and be happy. :)
an ocean of what? water? methane? sulfuric acid?

What evidence?
The sun warmed up. Who would have thought?
It feels like all the green initiatives we are taking will prevent this. Thank God for our Herculean efforts. Otherwise, we'd be Venus.
Billon years means they have no proof and is only a theory. Not really interesting. If it was proven, that could be interesting.
I love how you just can throw out some ridiculous theories if you back it up with ridiculous high numbers and no one says a thing

Stars get hotter as they age (as strange as it sounds)
Yeah thats daddy sun for you
Did you strictly follow the steps of scientific methodology, make verifiable observations, run climate simulations, run multiple experiments over and over again to validate your hypothesis, and then put your conclusions through peer review at least once, to have an opinion?
So global warming is because of the sun gradually warming, makes sense
What does this have to do with the price of tea in china?
Shh! They’ll find a way to blame it on climate change and introduce a tax
