    I made a follow up to this video explaining more: kzclip.org/video/eB3DJtQZVsw/бейне.html
    These cycles have little to do with the global warming debate. These cycles occur of hundreds of thousands of years and is unrelated to any changes over the past century. Please see my follow up video.

      @Bryan Ray
      this clip shows root causes in a very simple fashion, the one you suggest actually shows simplified geophysical effects which are ultimately intitiated by some of the astrophysical variations explained in this clip...
      your suggested clip would actually benefit if cut down a lot and something such as this clip is added to the beginning, as combined they show a simplistic overview of the important factors

    Very interesting, thank you.
    I saw a documentary where someone was studying ice ages - on [I think] Barbados! Every time the sea level dropped, a new layer of coral was exposed and died, and a new coral reef began to grow further down.
    The age of each coral terrace could be dated, and they matched the Milankovich Cycle very closely

      Most living things can adapt easily to changes like this that occur over a time scale of tens of thousands of years. The problem today with man made climate change is that the changes are coming just since the industrial age, not even two hundred years ago. And only a very small proportion of the natural world can make changes that quickly without dying out first.

      First off I'm not attacking religious people I'm attacking their religion and secondly the time for respectful silence when it comes to religious bullshit is over and it's time to call religion out for what it really is. As for willful ignorance sorry my friend but when someone says that evolution does not exist because they want to believe in creation that is willful ignorance at it's best, when someone says the planet is only 6000 years old because that's what their holy book says then that is willful ignorance. It is that willful ignorance that is childish and stupid. That's funny because there is absolutely nothing showing that a god has an impacted on anything either. Cheers!
      Edit: Oh and yes claiming that the earth is flat is also willful ignorance.

    Such a clear explanation with great graphics- wonderful - instant subscribe! As a young geology student in the 90s I was captivated by a talk I heard by Dr Brad Pillans about Milankovitch Cycles and sea level change and its effect on a tectonically uplifting landscape - creating so called marine terraces. Good examples of these are found in Whanganui and northern Taranaki provinces, as well as other areas in NZ. Yes, Ice Ages and warm periods are natural, but they happen on timescales significantly longer than human civilisation to date. For the first time ever, the Anthropocene is upon us.

And that’s just in Australia alone. This has an impact on temperature, which in turn affects when the next ice age will come.

    You correctly say that the extreme climate changes have been happening for 100s of thousand of years. But the Earth is billions of years old. It seems that continental drift has greatly increased the effect of the Milankovic cycles over the past million or so years by closing off the Arctic Ocean from the Pacific Ocean, cutting off warm currents from the Pacific, and allowing the Arctic Ocean to almost totally freeze over in winter. This ice mostly stays for well past June when solar radiation is strongest in the Arctic, thus delaying land temperatures from rising and melting winter snow cover. It is currently quite an unstable system, and the modest Milankovitch effects can have major consequences.

      @Dominant Wolf I would add that CO2 is not even particularly important greenhouse gas anyway, that spot takes water vapour by a very large margin, followed by methane, however CO2 is a `life's fertilizer` it being plant food, thus helping all life to flourish. The net-zero agenda is insane and it's important to resists it will all means necessary - presenting facts is a good start.

    It's not so much a question of the heat capacity but primarily a question of the mechanism of heat transport. On solid ground it is heat conduction where as on water you have convection. Convection can be magnitudes more efficient transporting heat from deeper layers to the surface thus preventing the formation of ice. Else from this: Great video and very well explained !

      This is an (unusual) almost clean sensible thread with only one troll-idiot so far. As correctly pointed out, snow can stay permanently on land through spring & summer (so permanent for millennia) and can build up and pack down into ice for millennia with a suitably-cool spring & summer, but can't do that on the ocean for 3 reasons.
      - Thermal capacity of water (heat content per cubic metre) is about double that of moist soil.
      - Water is more fluid than soil & rock (water flows a lot faster than soil) so the wind blows water around and mixes it and won't let its surface cool by 35 degrees or some such over just 6 months like happens each year with high-latitude land surface.
      - Ocean is salty so the snow melts at -1.8 degrees instead of 0.0 degrees.

      Because of the its magnitude. These natural cycles take centuries and centuries to occur; what humans have done in a little over a century is unprecedented and absolutely dwarfs these cycles. Secondly, in these natural cycles, a small temperature change causes a small change in CO2, which builds up to starting/ending ice ages. Man caused climate change is the opposite - we've dumped gigatons of CO2 in to the air and this is causing the warming we're seeing. However, the earth is a giant system. Like a boulder, it doesn't move instantly.

    On top of that, the Earth’s oceans and ocean currents have a significant effect on temperatures in the temperate zones. At one time, North America and Europe’s climate was much, much colder than today because North and South America were not connected by land. Instead of the Atlantic Ocean’s warm water current traveling up South America, into the Caribbean and up towards the North Atlantic, the current travelled around the northern part of South America into the Pacific Ocean. Without these warm water currents, large parts of both North America and Europe were frozen over with ice year round.

    Very good video. Worth keeping in mind that the atmosphere can trap more heat as a function of IR-active gas volume. Gases absorbing infrared light re-emit them in all directions, causing a loop (trapping them partly), instead of the radiation being reflected back into space. This doesn't directly have to do with ice ages, but thought it'd be a good idea to mention it as some may have come to the wrong conclusions in the comment section.

    Everyone should look at the ice core samples they go back a lot farther than 200,000 years. You will notice that it's never been warm for 6000 years like it has been this time but some of the hot peaks have even been hotter than it is now. But this is very interesting and needs more to look into.

    The Milankovitch Cycles started about 3 million years ago, and are still happening. We have been in an ice age for 15 to 20 million years, since the re-glaciation of Antarctica. People tend to call Glaciation Periods "Ice Ages", but they are just fluctuations within the current ice age. We currently have ice caps on both poles, definitely in an ice age, right now. We are at the top, or warm part of a Milankovitch cycle, called an Inter-glacial Period. It gets warm for 10,000 - 20,000 yrs or so, and then the cycle gets cold for 100,000 yrs. The cycles used to be much shorter and less extreme in temperature change, and had 40,000 yrs of cold. Now it is about a 100,000 yrs of cold.

      @lambo6012 it has happened suddenly before. One impact or super-volvanoe can change the climate in ways humans couldn't dream of, in one day. And that has happened more often then you've been taught to think. "Gradualism" is, I'm sorry to say, a bit of an old fashioned notion, they're finding. At least, unbroken, never-ending, pure "Gradualism", at any rate. It's actually a preposterous idea, to say "everything only ever happens slowly/gradually"....or to say "nothing has ever acted on nature as quickly as we have in the last 200 years".

    Dear sir, Thank you for making at least 2 million people aware of the Milankovitch cycle. It's not that commonly known. Except by the scientific community. Thank goodness the earth, currently, is farther away in the summer and closer to the sun in the winter. Without that the climate would be more extreme. We're already having enough extreme weather across the globe. Keep your woollies handy. The next ice-age is inevitable. We just don't know when.

      ​ @Orion625 typed "I'm curious what the other variable, CO2 in the atmosphere, does to this cycle. What if our CO2 emissions are actually offsetting the next ice age?" Yes. Of course humans can at present set Earth's average temperature wherever "they" want it within quite a large temperature range so as long as "they" want it too warm for a glaciation period (colloquially "ice age") they can do that and warming Earth just happens to be dirt cheap (cooling Earth is some orders or magnitude more expensive than warming Earth). The issue, almost certainly insurmountable, is that there isn't any "they", there's only "me" and "the rest of you arse holes" because competition to the death is the SOLE purpose of Life. As a matter of fact, right now there's a classic example that most humans have likely noticed going on in some land area humans call "Ukraine" (but some humans call it "Russia"). However that's just 1 trivial example of what's universal for Life and always will be. This is why the subtle, pithy "darugdawg" above typed "You cant test it because of well, time" in response to this thread start of "The next ice-age is inevitable". It's because there's a sub-minuscule but non-zero chance that the human brain will somehow alter by mutation from its basic condition, barely evolved from slime, to something that scrapes by the skin of its teeth past global thermonuclear war and whatever worse technologies they manage to find, and keeps societies with enough technology to set GMST where their experts decide it's most convivial for present Life and then simply holds it there for millions of years, so then no "next ice-age is inevitable". The pithy "darugdawg" above was a human future brain development statement and not at all a statement about the (obviously correct) glaciation period cause. Has to be said though that the possibility that humans will avoid wiping out themselves and all large-bodied Life on Earth for millions or billions of years is almost non existent.

    Interesting that earth is currently at or near the mean tilt of 23.5 degrees and heading toward the lower extreme of roughly 20-21 degrees. So the trend, as regards the Milankovitch cycle, is toward less extreme seasonal changes in the future. Maybe a reason for hope.

    Reading through the comments, I saw a couple of salient points that add to this effect that I also want to reiterate. The effects of the solar maximum and minimums, grand solar minimum in particular, and the effects of volcanic eruptions, especially those like the Toba eruption in Indonesia 74k years ago, and eruptions like Yellowstone, would have a major impact, but even eruptions like Mt.St . Helens and Mt Pinatubo had recently recorded effects on a global scale. Krakatoa was another major one that produced "the year without a summer". Grand Solar Minimum like the Maunder Minimum that produced the "Little Ice Age" between the 17th and 18th centuries should be considered too. This is an excellent explanation of yet another major factor in the natural, uncontrollable cycle of climate. Great video!

      "Krakatoa was another major one that produced 'The year without a summer'"
      That was actually the eruption of Mt. Tambora in 1815 which caused the summer of 1816 to be unusually cold. Krakatoa erupted (and completely obliterated itself) in 1883, and the volcanos we see there today are what was left after the eruption.

      Adam Davis: Hate to be pedantic on a good post, but I thought that the "year without summer" was in 1816 after the massive Tambora eruption in Indonesia in 1815. Although Krakatoa may have been the more violent eruption, in terms of material and ash put into the atmosphere, Tambora was far, far higher and had a much larger effect on global weather than did Krakatoa. In 1816 crop failures were reported in N America, Europe and other parts of the world. Even at more northerly latitudes such as the UK, in the summer of 1816, sunsets were marked by the sun turning blood red due to atmospheric contamination!

    it is important to note that those aren't the only factors that created ice ages in the past. the composition of the atmosphere and the distribution of the continental landmasses also caused major ice ages. large impact or vulcanic events (like flood basalts or extreme plinian eruptions) where able to alter the atmosperes reflective capabilities enough to block the sunlight and cause nuclear winters over large time periods. the distribution of landmasses is even more interesting. a larger concentration of continental landmass near or at the poles means that ice ages are more likely to happen and stay for longer, since the difference in albedo between land and ice is much bigger than the difference between water and ice. depending on the location of the continents the ocean currents also vary. and we have two wonderful recent examples on how they impact the earths climate: the gulf stream in the north, and the circumpolar current in the south. the gulf stream transports heat from tropical regions towards the poles and effectively acts as a barrier against (possibly) advancing ice masses, while the cold antarctic circum polar current is isolating the south pole from the warmer regions in the north, creating a positive feed back loop (due to albedo) that regulates the earths climate and keeps the southern ice masses intact.
    we have the luxury to live in a comparatively super stable time period regarding the earths climate. i hope humanity manages to not bork it up somehow. we are pretty good at destroying stable environments after all :)

    I often tell people, that we are nearer to the sun, in winter (northern hemisphere). We are always in an ice age, the current one began at least 2.5m years ago, Pleistocene it's known as, we are technically still in it, as the polar ice is retreating. There will be no interval as we begin the next ice age, so yes we're always in an ice age.
