- Paleoclimatic hypotheses suggest that approximately 750 million years ago, the Earth may have gone through a global glaciation known as the “Cryogenic Period,” in which all of the Earth's continents and oceans were covered by a thick layer of ice and reached average temperatures of -58°F (-50°C).
These temperatures are the lowest that have been on Earth in all of history and the factors that caused them could be present not only on our planet but also on the planets closest to Earth.
Considering the similarities that exist between Earth, Venus, and Mars, would it be possible that in the future these two planets will suffer ice ages like those our planet suffered in the past?
Can the conditions be met for the two planets closest to Earth to suffer global ice ages like the one the Earth suffered millions of years ago?
Join us on this journey of knowledge to find out!
Snowball earth
Snowball Earth is the hypothesis that suggests that the Earth experienced a series of global ice ages that covered most of the planet in ice.
The defenders of this hypothesis maintain that it is not only the most extensive glaciation ever experienced by the Earth but also the longest-lasting. In addition, its impact on the biosphere would have been such that life was close to completely disappearing from the planet.
Our planetary neighbors
Mars and Venus are the two closest planets to Earth; although these two worlds have many similarities with our planet, they also have enormous differences, some of which are:
Size: Earth has a diameter of 7,917.5 miles (12,742 kilometers), Mars has a diameter of 4,212.3 miles (6,779 kilometers), and Venus has a diameter of 7,521.8 miles (12,104 kilometers).
Snowball planets?
Although Venus and Mars are very opposite planets, under exceptional circumstances, these two planets could become snowball worlds, as happened to Earth 750 million years ago.
But how could that happen?
Mars Snowball
Let's start with the coldest planet of the two, Mars, which has a fragile atmosphere that is 100 times less dense than Earth's. However, it has gases such as water and nitrogen, which, under ideal conditions, could contribute to the decrease in its global temperatures.
Snowball Venus
In the case of Venus, something simpler could happen. Venus is the only planet that rotates in the opposite direction to all the others. This means that while the other seven planets, including Earth, rotate in one direction, Venus rotates in the opposite direction. Plus, Venus has the longest day of all.

Though you would still technically consider Venus rotation as being opposite of the other planets, my favorite theory in regards to it's "backwards" spin is that Venus was hit so hard that it caused a 180° flip (north ultimately becoming south) and that the planet still technically rotates in the "correct" direction, only upside down, and has slowed down drastically over time.
Great video and information !
Venus has an atmospheric pressure 93 times that of earth and is closer to the sun. Its thick atmosphere holds more heat. It’s impossible for it to freeze over unless the suns output decreased significantly. If Venus became tidally locked and lost all its atmosphere there would be a hot side and a cold side.
It would take time or require something extreme to cause it to happen but it could happen. Earth has gone though many extremes in temperatures over time and Mercury is next to the sun and it has a polar cap and a frozen side because it is tidally locked.
Maybe if volcanoes on Venus made very dark thick clouds that block most sunlight it could freeze over.
@@beringstraitrailway Well we're heard in the past that if Earth too cold it might trigger an ice age, There might be a point in which that could happen on Venus too due to the Nuclear Winter effect. Maybe?
@@Aaramlias If Venus was flung into outer space by a passing star or black hole it would definitely turn into a frozen dry ice world.
I think volcanos if anything would add heat to the planet. The carbon dioxide at Venus’s surface is 93 atmospheres and is a thick insulating layer. There’s no way it could cool with the sun beating down constantly. The sun would have to change. Earth is a different matter. The atmosphere is much thinner and loses heat to space much easier.
An ice age on Venus woud make it habitable.
Not necessarily, there is still problem of high pressure and lack of magnetosphere resulting in very high levels of sun radiation
Not necessarily.
What is an ice age on Venus that would make habitable?
Amazing videos
5:17 states that the water was "evaporated by solar radiation." Perhaps it is true, but I thought that it had more to do with the lack of an atmosphere. Liquid water cannot exist without adequate atmospheric pressure to keep it from boiling. In a vacuum, water will boil at 70 degrees Fahrenheit. What I do not know is if water will also boil at about 33 degrees in a vacuum.
Without the protection of a magnetic field, the atmosphere thinned, and the water simply boiled away until only the frozen water remained. This is how I thought it worked.
What you're saying is actually what we're most commonly told so I honestly thought the same thing you did.
Temperature is lower not colder. An object is colder.
At the same time? That would be so cool! (literally...🥶)
Yes, thanks, goodnight. 😮
How come in the video Venus and Earth are shown with similar rotation periods whereas Mars is rotating slowly retrograde? Mars has a rotation period similar to Earth and Venus rotates slowly retrograde, actually.
Nevermind....
You guys should also give measurements and temperatures in metric system units. After all, those are the units used by the scientific community and the rest of the world outside of the US.
Or since their channel is primarily aimed at lay people with audience analytics that are predominantly in the US, people who prefer metric can do the conversions themselves instead of grandstanding online as if they themselves are some sort of scientific figure.
@@The_Lucent_Archangel Or, like any other channel, they can just say both.
This channel putting out daily videos actually worries me a bit that the quality of their content will eventually go to shit. I prefer quality over quantity and a lot of channels that push out constant content (typically with the help of AI) typically get less intriguing, entertaining, and so forth, over time.
I would live on mars if humans had to evacuate earth
for ice you need water, so short answer no
Venus???
Why would Venus have an ice age it is the hottest planet in the solar system but Mars might have an ice age in the future
May have? Cryogenic period?
No
It's not part of a milankovitch cycle, but whether and when the next ice age happens is sure to be influenced by humans dumping mass quantities of greenhouse gasses into the atmosphere.
I am sorry, But I am not gonna watch the entire video without making judgement. This is the most stupid concept ever. Venus will never be an icy planet because of how close to sun it is and how hot it already is there, but Mars? Mars has always had ice age. Asking if Mars will have an ice age is like asking if a fish will ever learn how to swim.
Not so stupid ....it's a hypothetical only .. a what if situation,
It was discovered that Mercury has polar caps and one side of it is cold. If it can happen there ... why not on Venus if something extreme happened or it became tidally locked. Mercury isn't as hot as Venus and it's the closest planet to the sun. It will take a lot of time though for that happen.
@@Aaramlias Yeah, Venus is one thing, but Mars, what does it even mean for Mars to have an ice age? It is already too cold there for life.
An ice age for Mars would make it a lot colder, It couldn't get any colder then absolute zero though which is the temperature on the coldest planets and in space.
Agree that ice age on Mars sounds weird as by earth terms it's already in the ice age
Hello everyone. I just popped in to say, "FIRST!". I'll comment later after watching the full video.
No hate here, I just wish someone could explain to me what's so special or great about being the first person to comment under a CZcams video. My assumption is that everyone doing that must be kids or young teens, because it doesn't seem like something a matured adult would get excited about.
You'd be astonished how many adults do that...
@@jus10lewissr It's just good to be first for some reason. The best feeling is when you find an old video that has never has a comment and you get to be the first to comment. Simmilar to when you get a stamp you need to finish the set.
Well, for Venus the right answer is obviously ''no'', considering Venutian temperature and atmosphere, close proximity to Sun and growing of Sun's temperature with its aging. Why even place Venus in this video in the first place? Well, I'm looking forward to know what's this all about.
UPD: I see, we're talking here about special fictional conditions, not about some scientifically accurate possibilities. Then my earlier question is invalid. Video is still entertaining and interesting.

Hey insane curiosity I just wanted to be the first
