  • 250 million years ago Earth had one mass continent known as Pangea - a lush oasis swarming with life forms distinct to those that exist today. Then in almost the blink of a geological eye everything changed. Life itself was almost completely wiped out. But what was responsible for the biggest extinction event in the history of the planet? However, now scientists believe they have solved the biggest murder mystery of all time.
    In this truly spectacular documentary series, we go on a journey through the history of natural disasters. We'll be investigating from the planet's beginnings to the present, putting a new perspective on our existence and suggesting that we are the product of catastrophe. For each disaster led to another leap forward on the evolutionary trail form single celled bacteria to humankind itself.

      This is what the Geological Society of London concluded in 2020 after a major study into rates of changes during geological time:
      "the current speed of human-induced CO2 change and warming is nearly without precedent in the entire geological record, with the only known exception being the instantaneous, meteorite-induced event that caused the extinction of non-bird-like dinosaurs 66 million years ago. In short, whilst atmospheric CO2 concentrations have varied dramatically during the geological past due to natural processes, and have often been higher than today, the current rate of CO2 (and therefore temperature) change is unprecedented in almost the entire geological past."

In Earth's atmosphere it's more complicated so it's necessary to use the NASA formula or use the U.S. Air Force Space Vehicles Directorate MODTRAN. The more CH4 there is the less potent it becomes, suite rapidly. The more N2O there is the less potent the CH4 is. The more CH4 there is the less potent the N2O is. Also H2O gas shares the band so mnore H2O gas makes CH4 & N2O less potent. For facts it's necessary to study rather than lazily following, Parroting, your chosen Amateur Fake Scientist, or even picking up information from scientific sites, when you are unstuidied and don't know how to use it.

    Just 120,000 years ago, the earth was in a quite warm period called the Sangamonian. Sea levels were some 25 feet higher than they are today. Then, only 100,000 years later, the earth was in the depths of an ice age, and sea levels were some 425 feet lower than they are today.

      The point is, things can drastically change here on Earth all on its own. The whole "climate crisis" thing depends entirely on Humans being the only factor, when that is not true. In fact, our impact is negligible at best. Anything Humans can do is dwarfed by what nature itself can conjure up. And in our feeble attempt to "fix" things, we are just making things worse for ourselves. "Green" energy is a failure as its too expensive, not efficient, not reliable, not convenient, not recyclable (contrary to what we are told), and in many cases causes more pollution and damage to the environment just to produce than anything fossil fuel related.

      No, there is no error.
      The video states that "when [sulphur dioxide] mixes with water vapour in the atmosphere it turns into sulphuric acid". That is correct, though it does not explain how the sulphuric acid is produced. Notice that BOTH water vapour AND the atmosphere are mentioned. The sequence is as follows:
      Firstly, the sulphur dioxide reacts with water to form sulphurous acid:
      SO2 + H2O => H2SO3 (sulphurous acid)
      the sulphurous acid is then oxidised to sulphuric acid by oxygen in the atmosphere:
      2H2SO3 + O2 => 2H2SO4 (sulphuric acid)
      Sulphuric acid can be made by reacting sulphur trioxide, SO3, with water, as you suggest, thus:
      SO3 + H2O => H2SO4
      but that is NOT what happens when SO2 mixes with water vapour in the atmosphere.

If that is true, it would mean that the current scientific understanding of Venus is inadequate.

It was the volcanos that saved us - they increased the CO2 levels enough for some plants to survive, and came along very soon AFTER the extinction event (as seen from the sedimentary records). We are now quite close to another extinction event, because plants cannot survive with low levels of CO2. We need more CO2, not less, as many top level scientists are now saying.

    .Clarification 1.
    Warming of the oceans by itself does not rob the oceans of oxygen.
    Oxygen is distributed in the ocean by the AMOC.
    The AMOC is powered by the TEMPERATURE DIFFERENTIAL between the poles and the tropics.
    When the Earth warms, as we are seeing, the poles heat faster.
    When the poles are at the same temperature as the tropics ---
    the AMOC stops, and oxygen is no longer transferred to the depths.
    That is called a Global Anoxic Event or GAE.
    When the Earth cools, the AMOC starts again.
    Last GAE is believed to have been during the PETM, or
    Paleo-Eocene Thermal Maximum.

      craig k dillon... if the oceans are warming up, it is caused by the billions or trillions of tons of garbeege that the piggly municipal governments of the world shamelessly dump into the oceans.
      Everyone has heard of the poor sea turtles with a stupid McDonalds plastic straw sticking out of their nose because of all that human waste floating around in the oceans. How disgusting!!!
      If the Earth is heating up, it's from all that garbeege decaying in the oceans. And all that garbeege gives off HEAT AND CO2 as it decays, so in addition to the cycles of the Sun, without which, there would be no heating at all, it could cause the oceans and then the Earth to heat a tiny bit.
      This is because the Lion's share (well over 99.9%) of any heat on Earth is caused by the Sun. Without the Sun, even with the heat of decay going on in the oceans, Earth would just be another ice cube floating around in space.
      If you really want the Earth to get cold really fast, just ask God to move the Earth out another 500,000 miles or so from the Sun and see how fast the Earth cools down.
      If you don't believe me, look at Mars. It is 35 more million km or miles (not sure which) away from the Sun and its atmosphere is almost all CO2, and it is very cold there, so it is obviously the Sun that heats a planet, not CO2.
      Enuf with this global-warming propaganda please!!! Nobody could possibly believe that humans are better at heating the Earth than God's Sun is.

      Good question. But which asteroid impact would you be referring to? The Indian Deccan Traps occurred some 66 Mya and the Yucatan meteor impact at the K-T junction happened around the same time. Most geologists agree with the idea that such an alignment of events was likely related. The Siberian Traps, i.e., basaltic lava eruptions happened ca. 250 Mya, as this video mentioned, but an associated meteor impact at that time was not pointed out here. Rather, it is theorized by geologists who study the Siberian basaltic lava eruptions that it was caused by an enormous "mantle plume" raised, without much doubt, by the much stronger tidal forces which existed back then between the Earth and the Moon, owing to the fact that the Moon was considerably closer to Earth at the time. Moon/Earth tidal forces have waned since then, so maybe such an extreme event will be less likely to happen again. Moon/Earth tidal forces still exist of course, fueling the volcanic action we have all over the planet. It is a matter of degree in our era.

      The strategic use of key words, the thinly veiled subtext, yes, lots of propaganda in this one.

Science documentaries represent a narrative the producers wish to present, and may leave out inconvenient items that don't fit the vision of the director (among other things). For example, massive volcanic events do occur on time spans of hundreds of millions of years, so there may be one in the future. That could mean ten, twenty, fifty million years or more which isn't mentioned in the narration of the video. By the next one, if humans are still here they will be part of an unimaginably ancient species with abilities that would probably look like magic to us 21st Century primitives.

People were building stuff in Africa and Europe and Asia and the Americas not because of some master-race telling them what to do, but because they were people, and people like to build stuff.
      Add some survivor bias to that, and the situation explains itself. We have a small number of examples of things built with Roman Concrete and it's awesome and still sound 2000 years later. What we don't have are the thousands of examples of Roman Concrete built with inferior ingredients that crumbled within years or decades.
      There have been a number of humanoid species, but there's no evidence that any of the others built anything before we out-competed them to extinction.

      Reptiles didn't turn into mammals, both groups have ties to a common ancestor. No single animal "becomes" another. When populations of creatures start to settle into their environment, small differences that make individuals better at surviving in that environment get passed down, which causes change in the population. Eventually, that population will be in a completely different place from where it started.

    So to recap:
    1) The Siberian traps opened up, miles and miles of land covered in lava etc
    2.a) The volcanic activity releases sulphur dioxide, causing acid rain immediately, and lingering gas in the atmosphere causes rapid global cooling for a few years
    2.b) Carbon dioxide also released by the volcanoes causes a global temperature rise of about 5ºC
    3.a) The rising temperature changes climate patterns, causing it to simply stop raining in large areas, killing the plants at the base of the food web, causing the rest to collapse (I'm sure there were devastating floods in other areas but they're not mentioned by the video)
    3.b) Rising temperatures also cause the oceans to warm up, halting the oceanic currents that normally bring oxygen down to the lower levels of the ocean.
    4.a) This in turn makes the ocean a perfect breeding ground for anaerobic bacteria (ones that can't live in the presence of oxygen), which produce hydrogen sulfide, an acid that kills oxygen-dependent creatures. Between heat (which will also kill corals through heat stress) and carbon dioxide dissolving into the ocean, (forming carbonic acid which then neutralizes itself by binding to calcium in the water, leaving less calcium for creatures that need it for their shells and bones), both of which aren't mentioned in the video, as well as hydrogen sulfide, life in the ocean starts dying.
    4.b) The warming ocean also starts releasing methane, which has been frozen at the bottom but will unfreeze and turn into gas with just a few degrees of warming - and as methane is a much more powerful greenhouse gas than carbon dioxide, once the methane starts being released, it forms a feedback loop where it warms the atmosphere, then the ocean, where more methane will unfreeze the warmer it gets. This eventually raises global atmospheric temperatures by another 10ºC, causing another wave of extinction - again starting with the plants.
    At this point, only small burrowing animals could survive, off tubers and roots left alive underground.

      I strongly suggest you listen to this again. I assume you got distracted about 14 minutes into it since you missed what was said about the sulfuric gasses emitted, “acid rain”, etc.. I am only about 18 minutes into it and haven’t heard them mention carbon dioxide yet. But there is about 48 more minutes more.
      I am back. They just started talking about carbon dioxide. Around 19.50 minutes in.
      What I wish they would do is show what and where at least the major land masses were at that time. I keep forgetting when Pangea was supposedly formed and when it started breaking up. I think the breaking up started after this but wasn’t significant until after dinosaurs started to evolve.

      Same. Also we wouldn't be here without the extinction event, i dont believe that. Global warming alrarmist never include how plants and trees absorb carbon emissions. Or if our planet warms a few degrees, it would allow for more crops and plant growth. Or how volcanos erupt every year. Yet they want to blame it all on people. I would be more worried about the poles and rotation shift of the earth that supposedly happens every 8000 or 12000 years. Some say the south and north pole have started to shift. and no one can survive a complete flip.. They say that is the reason the one animal was found frozen at the north or south pole with plants not digested in its stomach from near the equater. At the end of the day I would image the earth will survive far beyond on life times unless idiots like bill gates try to block out the sun like he wants to do.

      No it doesn't and in fact it's not even close to the truth.
      Yes the wwT increased by +5°C. But CO2 accounted for perhaps 2% of that increase. The continent sized basaltic lava flow a mile+ thick, about 12.144 billion cubic miles, began cooling from >/= 1700°F per the zero and first laws of thermodynamics. That's trillions of trillions of BTUs. Where the hell (literally) do you think that heat from that thermal mass went? It went into the atmosphere.
      Heat your stove and your kitchen gets hot. Now imagine a stove cooling from over 1700°F the size of most of North America. The 5° leap in wwT was 98% from the 500k year long cooling of the lava down to surface temperatures, not the GHG effect. That this PhD (piled higher and deeper 🐂💩) doesn't tell you that but emphasized CO2 emissions is absolute proof this puff piece was about propaganda and pushing the CO2 climate hoax.
      That fools and morons do not understand that is proof the education systems have been designed to dumb you all down to simple automatrons of little useful value. If you are male, stop playing video games and read real books. If you are female, stop reading Cosmo, pick up a magazine that might expand your mind beyond makeup, breakups and how to be a better lover and grow that pea sized 🧠 inside your head.
      The climate increased 0.1°C due to CO2 and 4.9° due to the cooling of that enormous thermal mass (stove) sitting on the surface causing violent convections and winds for hundreds of thousands of years.

      Deccan Traps occurred around the extinction of the non-avian dinosaurs, the catalyst potentially being Chicxulub itself. Siberia was far older and far larger than even that. Siberia may have been part of an antipodal impact event as well, but there's less evidence of that, given how much time has passed.

      There is no way that anyone will die from the Earth warming up by 1 or 2 degrees over the next 100 years but chances of dying in a nuclear war are pretty good.
      Wake up and put your disaster scenarios into proper priority!
      And by the way, nuclear explosions cause many fires that will cover the Earth and generate tons of carbon dioxide.
      How's that for "a carbon footprint"?
      The images that you saw at the beginning of this climate-hoax propaganda video, is what Earth will look like after a nuclear war.
