The geological history of the Earth bears the traces of many global climate changes. Variations in temperature, radiation levels and the composition of the planet's atmosphere have proved to be a verdict for some species and an evolutionary impetus for others. Some major extinctions wiped out up to 90 percent of the species of that time, bringing life on the planet to the brink of extinction. Over the last 500 million years there have been five such global catastrophes, and right now according to statistics a sixth one is in progress, and the fastest known in terms of running its course. What is happening on our planet and why is its biosphere degrading so rapidly? Let's try to find out.

How do you like it, everyone?
Great vid, thanku
I always love your videos!
Very well done indeed. Thank you.
Was wondering it's been ages! Thanks for the amazing content!
You didn't Ask how many carbon dioxide is emitted per years by whole World fleet of all types of ships on every Sea and ocean. Nobody telling about this. Ships and pollution which they making - are they protected from showing the truth in media about theirs efect in atmosphere poluution?
Small compensation for such a large contribution; I wish it could be more. Thank you for all your hard work. Your vids are the highest of quality and your desire for excellence really shows in the end result 😃👍
Thank you very much!
:)))))
You stopped at 40000 years then jumped to modern times.
No coverage on the end of the last ice age and reasons for it. I was actually looking forward to your take on that. Never mind.
Good video though.
Interesting, if co2 levels drop we go into an ice age and if co2 levels drop to low them plant life dies.
Yes, very small. I would give a lot more. It took me seven weeks to edit this film. 7 weeks. 😢
@Max Payne then the content creator should b paying you fairly for that time, no?
I would love to go back in time to see all the prehistoric animals that existed!
If you could go back in time you could've met all those people whom we worship now as gods
@@greybeard716 I would love to meet Jesus!
You know in man's time there has been far more species of animal on earth than when the dinosaurs were around... but, since the 1940s we've killed 90% of it.
@@gtaitzJesus was just a normal man.
And if you saw the prehistoric beasts, you would be eaten quite quickly. 😂
@@gtaitzsounds boring i would love to visit genghis khan much more excitement.
Planet was here before us. It will be here after were gone. End result is, the universe is at work with greater things then us.
You lie! The planet will be gone when I'm gone.
@@ytsux9259😂
I lost my brain cells after reading this one.
Speak for yourself guy, I ain't going nowhere. 😊
Planet earth will always undergo a metamorphosis. Life will dissolve or evolve. Adaptation is for survival sake. Now the human thrives as animals that aren’t for consumption are deprived of existence. Realizing that is looking at endangered species of today.
Very impressive, that was a lot of information packed in half an hour.
I am absolutely amazed by the quality of your content. You are one of the best channels I follow. Thank you for the amazing work!
Thanks! Great video! I learned a lot i didn’t learn in Philly public schools lol.
This was excellent and I learned a lot from it. Of course, we learn the basics in school, but it is way more complicated than that. I find it fascinating and cannot stop listening. Thank you for filling in the gap in my education. I look forward to more videos like this one.
Well I hope you understand that climate change isn’t caused my humans…it’s caused by natural changes in earths climate🤦🏼♀️ It’s inevitable and will happen wether we are here burning fossil fuels or not. So please know that.
THIS is a well put together video that had me hooked right off the bat! Excellent!
I found a this fascinating and easy to follow, thanks for all your work on this it was well worth it ✨
You guys bringing proper and awesome content. High quality! ❤ thank you!
Brilliant 👌🏼I wonder somewhere in the universe is there a planet with dinosaurs that never got hit by a meteor.🙏
I think you may have missed the point.
What point have i missed considering it was imagination🤔
You`d have to find the exact environmental conditions of a planet and the same paths to the evolution of life through billions of years, which is impossible. I know the universe is so vast that you`d think why not? Well, even the tiniest variation would bring about completely different results. Unless you think about the multiverse, where infinity can solve the math.
@@MrEmmzo The multiverse is proposed, but not yet proven. If it exists then of course there is other identically intelligent life, including one of you which differs from all the others of you only by the fact that it has one more molecule of water in its mouth over the course of its entire life than you do (by the way, no disrespect is meant by calling you "it". I simply don't know your gender). There are also an infinite number of you who do not differ in any way, and the only difference is that a sub-atomic particle went in a different direction somewhere in that universe. For now, the Multiverse is a convenient "God of the gaps" type concept, and further, it has no bearing on what is going on in our universe. It's a convenient hypothesis for something we don't yet fully understand, and that's about the sum total of it.
One thing seems rather apparent now, and it is that we are not only unique in our planet's history, but also exceptional in it, if for no other reason than the combination of intelligence and an opposable thumb. Even if it turns out that a few other animals on the planet have a level of intelligence on par with our own, they are limited in regard to what they can accomplish with that intelligence owing to the fact that they are unable to manipulate objects to the degree we can. In terms of the long-term survival of intelligent life on this planet, that one difference might bring the end of all even somewhat intelligent life on the planet since we seem to not be intelligent enough to reign ourselves in and prevent what we know we are causing.
Contradicting myself only a little, it seems to me that we're pretty stupid when it comes down to it. We're certainly not smart enough to be a successful species in terms of how long our presence on the planet is concerned, as no other species has come close to nearly ending itself as quickly as we have. We're pretty exceptional alright, and if our evolution is any indicator, we may well represent the pinnacle of what life can become. If our brevity of existence is any indicator, that could also explain why the universe is silent. Similarly intelligent and physiologically capable life could have occurred millions of times, yet never have lasted long enough to make itself known. We certainly haven't.
It's not impossible. Maybe not exactly dinosaurs, but some sort of alien life that may look like dinosaurs.
I can imagine how terrified the dinosaurs must have been 😔
😂😂😂
Yeah... sad Noah didn't have his ark back then 😂😂
Right, poor babies
Don't worry, I will save them! 💪
Build a time machine & go save em.
It was worth watching, very clear information, lending the mind to grasp around the subject, bravo!
so much information in a short time, amazing editing skills! thank you!
I love this channel; from the graphics to the narration to the delivery of the well-researched topics, it’s all so well done! Thank you!
Amazing! Such hardwork and research you have done for this informative and interesting video. Kudos!
Amazing content 👌
Very high quality, Thank you!
Absolutely amazing. Every video I watch just makes me want to learn more.
Great video! Love watching your videos. Thank you 🙏
Not even a minute in this video was unnecessary or tiring. Soo beautifully made . Soo informative and really a quality work.❤❤.
New subscriber. Really impressed with your videos and look forward to watching past content to catch up to new uploads
Content like this is CZcams at its best. Thank you.
Great video: entertaining & thought provoking. Thanks for making & sharing!
Awesome video! Thank you! Look forward to more!
Thank for such outstanding graphics, really good video editing, and wonderful narration.
It is said the Chicxulub asteroid came in at approximately 60 degrees to the horizon, one of the worst angles it could have. If it hit head-on, much less ejects would be pushed into the atmosphere. If it came in from the horizon, it would have slowed down significantly or crashed on its side, which would minimize the explosion and ejecta.
Ive seen something about that it also was a lot of sulfuric rock where it hit that made it even worse. And on top of that it was spring in the northern hemisphere.
Its like a cake with many layers of worst case scenario.
@@Makabert.Abylon damn
I always wonder why it didn't explode in the atmosphere like so many other large objects have. There must have been something which was different about the atmosphere which prevented it. Not that an air explosion would have been any less impactful. Even an air burst (called a bolide) of an object that large would have had devastating effects, and the result wouldn't have been much different except for not making a huge crater in the ground and the associated liquifying of rock, among other things. Water in the area would have still flashed to steam and a huge tsunami would still have been generated. Maybe there would not have been the great fires, since bits of the Earths crust wouldn't be raining down everywhere, and the eruption of the Decan Traps might not have taken place, since that seems to have been a direct result of the shock generated by the impact. The energy of the bolide, the shock wave generated by it, the vast amounts of water flashing to steam and the displacement of that, and the instant vaporization of all life in the area under the bolide would still have been plenty catastrophic to have ended the dinosaurs though.
That is, if that's what actually did them in. So far, there have been no dino fossils found in the KT boundary. You would expect to find many there if that's what killed them, but so far, not one single one has been found there. The fossils are all found a good bit below it; enough to represent maybe a few thousand years before. Even in areas very distant from the impact site you never find dino fossils within the KT boundary. It does kind of make one wonder if that's really what did it, or if maybe that was just the coup de grasse on an already vastly reduced population. There is also a possibility that small mammals evolved to eat dinosaur eggs, and much like rats have done in Pacific islands to birds, drove them to extinction by eating all their potential offspring while they were still in the egg. There was a sharp rise in small mammal life and diversity which took place at about the same time as the dinosaurs went extinct. If they were animals which lived only on the ground, that would explain why birds survived, and not dinosaurs.
@@Chompchompyerdedmodern birds are Dinosaurs.
@@Chompchompyerded The asteroid was much larger in space than when it hit Earth. The atmosphere already broke it down smaller.
Very interesting!! Subbed.
I remember from Spring to early Autumn it was generally nice weather; (I was 5 in '67, and had a lovely holiday with my parents on the East coast of England). Everything was nice, up to the late '80's, then the weather seemed to change, loads more rain instead of nice warm sunny Springs and Summers. Now its usually bad weather now. Heavy skies, instead of nice summery days. The climate seems like a runway train now, its going to be near impossible to stop it. I see babies, and often wonder what a crap climate,rising seas etc will impact their lives, especially their great great grandchildren...
Thanks!
Great content as always 🤙🏾✊🏾
This is so nicely done. So weird you dont have millions of subs. Good work.
Wonderful work done here!
Thank you so much for this beautiful video. 📹
nice work! i enjoy your videos a lot)
Really appreciate and enjoy your videos..truly inspiring.
This is a beautifully presented history. It ought to be used in schools.Thank you.
Life always finds a way...
The world will recover after the next mass extinction no matter who or what causes it 💚💚
Life has found a way so far. On this planet, and no other in the solar system. Or in any other which we know of. Just because life has found a way thus far does not mean it will forever. Further, technologically advanced life has only occurred in this solar system only once, and we have no evidence that it has occurred anywhere else. The fact that we are the cause of the current mass extinction, and that we may also be a victim of it should worry you and everyone else. Single celled extremophiles might find a way, but we will be resetting the evolutionary clock back to near the beginning if we don't get things under control. Is that acceptable to you? Are you okay with condemning your descendants to an end which is unimaginably worse than anything which you can imagine.
There is an eerie silence in space on all wave lengths. It is possible that we represent the pinnacle of intelligence and technical ability in the universe. Someone has to be that. It could be that life is common in the universe, but that intelligent life is not. The striking thing is that as the most technologically advanced life form on this planet, we are not nearly evolved enough to overcome our wants and desires, and therefore are not intelligent or advanced enough to prevent our own demise by our own hand. That's something to think about when you say that life always finds a way, or that the world will recover after the current mass extinction. It will not recover the way it was, and we nor any other technologically advanced species will be a part of that recovery unless that species evolves to cooperate. That is unlikely since that is all tied up in the urge to reproduce and to always attain an easier lifeway. Evolution selects against it. Prove me wrong by going net zero, if you can.
It will recover after our nuclear war😊 obliteration but it will take a really long time
@@christmasw330 It will if by "recover" you mean nothing more complex than single celled extremophile organisms. Technologically capable Intelligent self-aware life won't.
@@Chompchompyerded not for a long time, but it will evolve. Again. Hopefully not with twiddly opposable thumbs that get up to mischief. Maybe something like cetaceans
True but it will still suck beyond imagining for those organisms during it. It goes without saying that this includes us.
Wow just finished the video and while the entire thing was extremely well done, the last while of the video had me in such anxiety ! It’s crazy what we’re doing to the planet, like we don’t have an actual effect on it! Scary stuff
Excellent episode. Great presentation and story telling. Fascinating stuff.
Very interesting,thank you !
Great visuals and good information. Bravo!
Brilliant work thanks ❤
Great video! So interesting. I need to watch it again. 😃
Lovely video with in-depth research.
I bet the air in the sky and the water in the sea was so pristine when the dinosaurs were around.
A much more volcanically active time, so ejecta and smoke. Enormous dinosaurs make enormous farts. Huge piles of dung. But at least with the higher CO2 levels vegetation was prolific and vigorous to allow it to regenerate rapidly after being ravaged by herds of massive herbivorous animals
Except for their farts and huge dinosaur turds.
Outstanding ❤
That was extremely interesting,thank you so very much.
Great content, mind-opening as always! You deserve more subscribers.
Wow thank you for that it really was great and informative
Wow . Amazing work. I understand our world from the beginning to the present. What an outstanding research and knowledge.
Great video, really interesting
i would love to show this to students! very simple and easy to understand eye opener.
Great video, scary how quick things are changing. A better environment starts with ourselves!
"quick" 😂
@@kojo_143east haha you are right, “quick” indeed. Altho noticing changes in climate during our short lifetimes is crazy if you think about it.
@soupdeluxe The two leading climate scientists refute all claims of any measurable change in the climate due to humans.
In the 60s they said the Earth would burn up, in the 70s they claimed there was another Ice Age coming within 20 years. In the 80s it was acid rain and greenhouse gas. Now it's carbon, nitrogen, and methane.
The only thing that happened each time was the introduction of a bunch of new taxes. PERIOD.
The Earth goes through changes, many have been far more drastic than what we've seen in the entire span of human existence.
If you want an answer to global warming look into the similar warming over EVERY SINGLE planet in the Solar System.
We're moving through a superheated gas cloud. Voyager proved this recently.
Stop being a sheep. All of this climate change, net zero, carbon footprint B.S. is designed to make people rich at the expense of the gullible.
@@soupdeluxe What makes you think you can do anything about it? Your inflated brainwashed indoctrinated arrogant human ego?
@@soupdeluxe what’s crazy is how poorly we adapt. This isn’t new, rapid climate swings have happened to many humans, many times.
Not to mention all of the other animals. Some win, some lose. Sink or swim.
Great video! A little heavy on the alarmism at the end but still worth watching
I enjoy every second 😮 amazing work.
Thank you for this great vdo❤
Instantly subscribed...never is enough paleontology videos
Quality videoship, if such a word exists. Excellent!
This is nature❤, I wonder what will happen to this earth in the future
Nice work dude
This was pretty eye opening. Makes me wonder what impact pole shifts will have again soon.
As always your channel produces some of the best content on CZcams. Am I mistaken, I thought in your intro you used to say Kosmo, first in space? I may be remembering that wrong. This video is well researched and presented. Thank you for another thought provoking subject presented with the highest quality video.
I love these kinds of vids dat give a possible look at life on earth in past millions of years.
We are thoroughly doomed to annihilation it would seem. It was one hell of a run. Mostly a horrific run, but one hell of a run nevertheless. Time for some future species to take over, and for us to be completely forgotten in some millions of years. Adieu
We wont be forgotten never our structures on the moon will remain there forever until the moon disappears or explodes voyager one and two will keep going so many thing’s humanity has done will remain for a future species to check or probably not probably we will remain
great video with an excellent message. I was totally captivated..
fabulous animation with nice breaks in between your voiceover gives the video more asmr feels. I could see the work you put in your videos. Please keep it coming!
Amazing content 👏
Great job!❤
D best content I see bout this days🤝 Dense in knowledge. With a reminder that the world needs to be taken care of.👌
I can’t handle the way he says glaciers .. killin me smalls 😂😂
Love it as usual
I've shared this on FB news feed, and a couple of my groups, everyone should be aware
Most valueble chanel that I've ever found❤️🔥
Amazing video. Just WOOOOOOW
Definitely worth watching. Thanks for the content. Only few will know where we are to go from here. If you have the resources to attempt to get to the next stage of an evolutionary civilization, we work together or only a few will survive. Most issues bring a great deal of simplicity but at what cost? How can such an event spiraled from humans for the sake of humans to be the demise of humans.
No offense but that sounds like some commie gobbledegook
I love this channel, and the video was incredible as always. That said, this fear mongering about climate change is continuously blown out of proportion and my biggest frustration is that doom is the only assumed outcome. Anyone claiming to KNOW what will happen are ignorant. For example, there are some aspects that suggest the warming planet is positive for plant life, not negative.
Thank you for your work i liked IT
Great content. I wish people will change their minds and living ways.
This channel is a gift🙏❤
Oh I like it! Thanks, dude! 👍
In a nutshell, only the last 5 million years CO2 levels have been lower then today. The planet's norm is high CO2 levels and high temps.
You know what else is the norm? Lack of technological civilization disrupting natural climatic cycles by changing the established atmospheric composition. 🤫
@@ProfezorSnayp the composition changes all of the time with or without humans. Humans going electric no impact at all, same result. Polar icecaps going to melt with or without humans. Sun is heating up and will continue to do so until the end of its main sequence lifespan. Climate change has taken place since earth day 1 and will continue to do so until the outer envelope of the sun gobbles us up. Accommodate and acclimatise 👍
Very very informative an educational, I have enjoyed this an more content like it is very interesting
Great video, love this kind of stuff, and very interesting, my only hope is that in my lifetime we see civilization reach level 1, but with the way we are going, that will never happen.
I like your videos very much, it's very interesting how life on earth progressed
Awesome!
Other than having to pull a Celsius chart up for this video,content is amazing 👏 thank you.
Thank you. I now know a little more! I hope that we make it through this mess we have made,
Awesome 👌
These videos are awesome 😎
Loved it ❤
This was an amazing video ! Unfortunately the search of power and greed will prevent the good future that we should all search for!
It could, but we could one by one start to effect a difference. We each have to personally commit to it though. I have done so, but am always open to new ideas. If you'd like to discuss it, and see what you and I can do, as well as how we can get others to join in, please respond here. The dialogue and action has to start somewhere. Let's not leave it to someone else.
@@Chompchompyerded look, thanks for responding but here’s how I see it. 50% of the world dont care about it and do what they want and 50% of the world buys things from the other side pretending to be a green but the fact is that the majority of stuff is manufactured in the east and then sent to the west. Unfortunately you have those who buy from polluters and pretend that is their problem and then you have the polluters. One person cannot make that much of a change. Maybe on the brief occasion but honestly, not enough. The way things are now isn’t going to change unless we did the world of greed and power.
Puts things in perspective near the end of the video
Peace! Amazing 🥲 content and information! 🙏 Thank You sir!!!!!!!!!!!!!🎉
This is awesome!!!!!!!!!!!
This was well done. Great hypothesis on what actually happened.
Great video. Cheers 🥂
Sea levels rising won't happen lol. Mr Wizard in the 80s demonstrates why with a glass of water and ice cubes. Water takes up more space when frozen. There's way more ice under the water than above. The difference in volume will cause barely noticeable changes in sea levels.
Thank you 😊
very good content, or should i say one of the best video about earth ive ever seen
explained well, more than our professors and really made us think deeply even more about on how we can still save the planet. its crazy bcuz we people cant help ourselves but to watch and stare at our slowly dying planet. and i dont think that the apocalypse that ended the dinosaurs wont happen again. the world, everything in it is in a cycle. we dont even know what part of the cycle we are in ryt now. godbless everyone
