      @The Paradox Destroyer It's important because it shows us how some things work. That's the guy who created the most accurate calendar ever, his knowledge about climate changes was something else. Because of him, we know a lot today.

      @The Paradox Destroyer Many would beg the differ! You can't disregard all of the other factors that drive Earth's climate. We can't reliably forecast tomorrow's weather and sometimes today's weather let alone the next year or decade because there are variables that we exclude or don't know about. Human effects on climate are small compared to Nature's.
      The "Climate Change" (love the new name) proponents have and "scientists" have left out the other factors effecting climate on Earth, such as water vapor, the Moon, Earth's orbital mechanics, and Sun cycles (although this video on the Milankovitch Cycles eludes to it's effects). You can't ignore all the variables your find and claim to have the definitive answers to any issue. "Climate Change" is a political agenda about power and money.

    The Mojave Desert in California was once a wet and watery paradise with lakes, rivers, giant dire wolves and flamingos. The first humans in the Mojave region even experienced the large bodies of water and rivers. Paleolithic records reveal they had boats that traversed the massive lakes.

    The "distance from the sun" from Greenland to Sahara is so tiny it does not affect the energy in the rays. In the north the rays are spread out and will have less warming effect. And if the rays comes in at an angle, in the north the rays have to pass through a longer distance of the atmosphere before it reach the earth's surface, and then reducing the energy in the rays.

      I think it's about the land mass distribution as well. There's more land mass in the northern hemisphere. When the North hemisphere is facing the sun the land heats up the earth more. When the southern hemisphere is facing the sun more, the earth is cooler because its harder to heat the water.

    Remember, the tilt of the Earth determines how many hours of direct, concentrated sunlight you receive. That is what separates summer from winter, not the tiny degree of change in how close or far you are from the same. It is the angle of incoming sunlight that matters.

      It would help to think a little further than that. The sun itself dictates whether the earth even has a stability to its weather to name seasons, or irregular weather, based off of its irradiance output. Even at distinct tilts the earth can still be receiving virtually no sunlight compared to a previous century due to increased condensation from a weak magnetic field allowing GCR"s to Penetrate earth's core at deeper levels.

      @Jonathan Gems : It is indeed the tilt of the Earth that determines seasons. That's why it's dark for months in the Arctic in winter while the sun doesn't set in the Antarctic. It's Australia has summer when the US has winter. The longer summer days absorb more light and heat.

      @Stefan Stanković "climate change doesn't exist, it's just the change of season. That's all it's going to do what it does all the time. And the storms are pretty consistent in the same areas. Kind of like how Jupiter has that big red storm spot. You might be seeing more of a storm, and others will be seeing less. People need to start doing things in the way of prevention and don't build in areas that are problematic unless the structure is built to be able to withstand such storms. All it takes is to use their heads and to do some prevention and it would be dealt with already. We would have a savings on insurance. And if not a savings at least stronger buildings to withstand.

      Except...Big 🚩here with sun distance being responsible for change in temperature. It's nothing to do with distance. At 93 million miles with the distance varying a couple of thousand miles, the heat change would be hard to measure and way less than 1 degree. It has everything to do with the angle of the to the sun's rays. This is seen easily by everyone outside the tropic of Cancer and Capricorn. As the sun drops in the sky, much more area receives the same amount of radiated heat from the sun.
      Until in some areas, it disappears completely.
      I tried to explain this to my grade 10 biology teacher and got an E. The next semester, a substitute physics teacher corrected him, and he changed it to an A.
      I don't think this guy made it past grade 10 physics.

    The Milankovitch "trifecta" for chilly northern summers:
    1. Maximum eccentricity in the orbit (currently in a medium phase)
    2. Aphelion during northern summer (currently very favorable for ice age onset!)
    3. Minimum tilt of axis (currently medium)
    Line up all three of these, and the summer sun will be as far away as possible and as low in the sky as possible. That allows glaciation over Canada & Siberia to really take off!

      @Flynn Lives : The obliquity changes the seasonal difference in distance from the sun on a 100,000 year scale. Changes in tilt varies the amount of time each hemisphere receives sunlight. These two things change the amount of difference between seasons depending if they are in sync or not. Warming trends tend to release CO2 which increases warming which increases atmospheric water vapor and methane. These increase the warming more until the cycle reverses and the next glaciation occurs.

    • Flynn Lives
      Flynn Lives Ай бұрын

      @LR Vogt Thank you for agreeing with my point. First - the original thread that I posted a reply to said "Its ALL about the distance" which it is not. Second, my reply was that SEASONAL change is caused by the relative change in angle that light strikes the surface and the duration of the daylight. Milankovitch cycles and Eccentricity changes are measured over 10^4-10^6
      years and are NOT seasonal. Their effects are felt year round over long periods of time. So while they do effect climate/weather (or your comparable term) they are not seasonal. Obliquity , the angle of "tilt" with respect to Earth's orbital plane changes from 22.1 and 24.5 degrees - which is what I said - change in angle the light strikes the surface. Axial precession the gradual shift in the orientation of Earth's axis of rotation - is a change in relative angle not a change in distant. Apsidial Procession is also not a change in distance, but a change in the orbit relative to the sun, which changes WHEN the earth is at min/max distance, but does not change the distance. So, thanks again for confirming - angle and duration not distance are the driving factors. ~Cheers

      @Lookup VeraZhou Yes, I realize what you said - it is just wrong. One more time - the distance from the earth to the sun - does NOT cause it to be warmer/colder - it is the angle that the sun light it strikes and the duration, and the planet is CLOSER in JANUARY when it is winter in the northern hemisphere, and FARTHEST in JULY when it is summer in northern hemisphere - the earth is over 3.5million miles closer in Jan, than it is in July - that alone should be enough to demonstrate - the variation in distance as the earth transits its orbit is not a factor. There are really great online explanations of this - avail yourself

    The geologic arrangment of earths land and seas also play a massive part in this. Before Australia separated from Antarctica the Southern Ocean did not have Antarctic Convergence. This flow has worked to stabilize weather patterns in the southern hemisphere. Think of the effects the Rocky Mountains have on air currents, thus long term weather patterns. There are so many factors on such long time scales that humanity will likely never figure out how it works.

    It's important to note that the larger ocean area in the southern hemisphere more than offsets the effects of summer perihelion/winter aphelion down there. More ocean = less extreme seasons.
    It also means that the climate of the southern hemisphere cannot make or break ice ages. There are no large landmasses in the middle to subarctic southern latitudes, unlike North America and Eurasia in the north. You need subarctic land surface to support increasing snow cover.

    I would suggest that when the Earth's orbit is tilted towards the Northern and Southern Solar Hemispheres, it receives less solar radiation due to the Sun's Magnetosphere.
    If studied, I am certain we will find that the Sun radiates more from the poles and the equator, as the magnetic interference is far less in these regions.
    I have come to this conclusion due to the interaction of solar radiation with our own Magnetosphere.
    Food for thought 🤔

      The sun's poles are the hottest points, and temperature declines by about 100C as you head to the equator. The distance is so great and the sun so vast that the radiance reaching the Earth is essentially averaged and constant WRT the sun's varies latitudinal energy output.

    Yes, ocean currents from melting massive amounts of ice can cause the cycle too break down, air currents i.e., mountain ranges raising or falling are huge part of the ice ages too. Then the earth and all its variations of orbiting its tilt, wobbling i.e. Milankovitch Cycles, sun spots also go in cycles add all these up you could have ice age.

    The effects of continentality will also enhance the harshness of winters when the northern hemisphere is finally experiencing aphelion in its winter. Land warms and cools much more quickly than water and because the majority of the earth's landmass is in the northern hemisphere, it will lead to even colder conditions in interior regions on the continents. Siberia and interior Canada will become much colder and likely fuel the next period of glaciation.

    Excellent video. As some others have commented, would also value an appraisal of the effects of variations in solar output - and the approximate magnitude of their potential contribution - as compared to Milankovitch Cycles. Understood: this raises the level of complexity even further - but at least a mention of this would be appreciated. Even in not-so-distant historical times (e.g., Maunder Minimum of ~1645 - 1715, coinciding with the middle of the "Little Ice Age") well-documented variations / changes have occurred. Then throw in (unpredictable) heightened volcanic activity, etc. Bewilderingly complex when one attempts to sort it all out!

      Between 13900 BC and 14000 BC, a 100 year span, Earth's temperature rose 5 degrees Celsius. This is one of many intermediate spikes in the ice core data, not including the 10-15 degree Ice Age spikes. Humanity lived through this period just fine and had no heavy polluting industry to speak of at that time. In the past 200 years, which is twice that length of time, Earth's temperature has only risen by 1.2 degree Celsius.
      A minor natural change in temperature that is in fact physically unstoppable and inevitable has been pathologized and blamed entirely on human activity in order to establish a carbon tax which allows governments to monitor every action of every person and tax them for it. The climate changes. Changes in local weather ARE NOT evidence of climate change, however, human activity CAN affect weather.
      Changes in climate, not weather, are driven by the Milankovitch cycles, primarily precession of the equinox, which changes the angle of Earth's tilt over a 25,000 year cycle, and thus changes the total amount of sunlight the poles receive, known as the insolation cycle. This insolation data from ice cores coincides directly with the rise and fall of the past 4 Ice Ages. Furthermore the temperature was higher than it is now prior to the last 4 ice ages, and also coincides with the insolation cycle and the rise and fall of the Ice Ages. That's right, the temperature was higher back when humans were hunting wooly mammoths than they are now. No heavy industry to speak of. If no other fact about climate change remains in your memory, let that be the one.
      This fact suggests that the warming we are experiencing now is that final spike of warming that occurs right before Ice Ages suddenly set in. Climate change is real, its not caused by humans, and we are headed into a regularly scheduled Ice Age according to every indicator, not a waterball Earth condition where the remaining icecaps in the already warm period were in fully melt away. Sea level rise cannot occur with slow melting because of isostatic rebound. Rapid melting is required to cause the floods and sea level rises that climate extremists harp on about.
      Rapid melting is caused by a sudden addition of lots of heat to the atmosphere. This is how the Ice Ages end. The most popular theories on how Ice Ages end are supervolcanoes, comet impacts or massive solar flares. However, comet impacts best solve the issue of regularity, as the Ice Ages seem to last a similar amount of time, every time.
      If we were to somehow try and affect these Milankovitch cycles, such as slowing down the rate of precession, it would spell real cataclysmic changes to Earth's surface, the likes of which climate extremists only dream of to justify the implementation of their carbon tax scheme..

      @Hermes Trismegistus DO events produce opposite effects in the Northern and Southern polar regions, called the Polar See-Saw. As I said above, these large temperature swings are highly localised, and I recognized the 5C swing that was mentioned as being a Greenland temperature swing. Greenland is also the site for temperatures that 9,000 years ago exceeded today's warmth, and this then was caused by particularly intense insolation in that region owing to the configuration of Earth's orbit at the time. The orbital mechanics that melted the ice sheets and thawed Earth out of the last ice age saw the Northern hemisphere receiving more insolation than the South.
      Warmer temperatures in the past don't prove or disprove anything about the current causes of climate change. Just because there were forest fires before humans doesn't mean that humans can't cause forest fires.

      @barryschwarz The Vostok ice core is from Antarctica. Both Greenland and Vostok ice core datasets confirm Daansgard- Oeschger events which alone disprove the current manmade climate change hysteria, but the fluctuation I'm talking about is not even as extreme as one of those events, its just one of the dozens of rapid warmings in the record, which were more rapid than the current warming. Greenland shows it actually being a ~10 degree rise while the Vostok core indicates a ~5 degree rise.
      I bet you didnt study both datasets youre just aware that there are different ones and assumed I hadn't studied them both so you made that ignorant comment.

      @Hermes Trismegistus "100 year span, Earth's temperature rose 5 degrees Celsius." - I believe you are basing this on a single ice core from Greenland. That is not a proxy for what happened globally. Also, typically the NH Arctic region warms faster than global, so IF this was a global phenomenon, the 5C would represent to peak of temp change on the planet at that time. However, Antarctic other ice cores don't show this massive jump, so it appears to have been a local effect, and possibly to do with inhomogeneities in the proxy (ie, elevation changes).

    I've known about Milankovitch cycles and the "Goldilocks Zone" for decades now. What amazes me is that the distance of Earth from the sun doesn't vary at all that much, and our axial tilt doesn't vary all that much. But when it does...it produces things like the "Mini Ice Age" of 1815.
    And just so people understand why Milankovitch cycles are a thing, there are a few things to consider.
    1) The physical property of impulse, as related to motion. The idea here is, imagine you have two boxers throwing punches. If one boxer moves away, stands still, or moves toward the other boxer, the amount of pressure damage he'll suffer will change, depending on his velocity, relative to the punch thrown at him. Or, put another way, the additive result of velocities will tell you how much damage something will cause -- or as here, how much energy the Earth will receive from the sun.
    2) Milankovitch cycles can be thought of like a car on a road within painted lanes. The idea is that a car can move laterally while going down the road. This is what it is for Earth to be in the "Goldilocks Zone," which isn't a fixed distance from the sun. We have variance within that zone that very much determines if our average temperatures per year will be hot, warm, or cold. And it has to do with the the impulse of the energy the Earth receives, relative to our axial tilt (increase or decrease of surface area of the EM Field that allows solar radiation penetrate into the atmosphere), as well as where we are within our "lane" as we go around the sun. Are we closer to the sun (receiving slightly higher frequency radiation), or are we further away (receiving slightly lower frequency radiation)?
    It is these things that I believe have more to do with overall climate change than any amount of anthropogenic climate change mankind could ever actually do. Not only is the Milankovitch cycles constant or continuous, but climate change is about radiative and ionized energy from the sun. It's always been about that -- not a "devil compound" that life on this planet needs to live.

      Sorry but you are wrong, one of the reasons the North experiences more severe cooling is that most of the land mass is in the Northern Hemisphere and as such snow has a greater capacity to reflect and cool as there is more of it. At the extreme of the orbit the distance from the sun is reduced by as much as 40% of incoming radiation, more effective than the tilt angle difference of 1.7 degrees. It's a combination of all the extremities of the cycles that add to the massive drop in solar energy, hence every 100,000 years, and not the 26000 for the tilt angle.

    As someone who lives in Minneapolis, Minnesota, and was born in another state which borders Canada- New York, having graduated from Cornell University, in Ithaca, New York, I have thought long and hard about the seasons and the really severe changes in climate between winter and summer in the northern areas. The difference between winter and summer, which is severe in most of the places I have lived, is not a consequence of what most people think. We are always the same distance from the sun. Seasonal changes to not make a significant difference in the *distance* we are from the sun. Huge differences between winter and summer are the result of a dramatic difference in the number of hours of daylight. This may seem counter-intuitive, but after you give it some disciplined thought you will understand that it is indeed the difference in the number of hours of daylight which makes the huge difference between summer and winter. Anyone who has stood patiently and watched the full extent of a total solar eclipse really appreciates how cold it gets when the sun is almost completely blocked for even a few minutes. The number of hours of daylight is truly the essence of the difference between summer and winter. I urge you to do some deep thought on these issues.

      @Nicolas Buzzbuzz "scientists paid by lobbies ignore his work" LoL! Do you think that Milankovitch cycles are the reason that the world is heating up right now? The cycles are currently in a cooling mode. Nobody is "ignoring" or suppressing his work. It's basic undergrad material.

    So, seasons aren’t actually primarily dictated by “how close to the sun you are,” but by the restive angle of the ground to the incoming sunlight (or the angle of the sun in the sky)

    Once I read that if it was not for the current amount of green gas currently in the atmosphere we would be already back to ice age.
    Another point to consider is that the position of continents is also a factor since no ice age was confirmed during the 200 million years of dinosaur era and I guess earth didn’t start orbiting the sun only after that 😀

    less ice means less reflected sunlight, but warmer also means more water vapor, which means more clouds, which means more reflected sunlight

    Also, yes the S hemisphere is in phase with being closer to the sun in their summer and further away in winter but they don't have more extreme seasons because there is much less land mass and more water which moderates their seasons.

      Plus the latitude explanation given at the start is very basic. The UK and North Western parts of Europe are on the same latitude as Canada but have much milder Winters due to the gulf stream. The major Oceans are massive players in the distribution of heat and cold, Fresh water melt from glaciers spilling in the the sea is another one to.

      @No Great Reset "CO2 gradually goes up after temperature": indeed. But CO2 is also a green house gas. Contrary to what you write, CO2 stays long in atmosphere, more than 100 years (methane, less long, but then becomes.... CO2). The issue is that Earth temperature is due in part the the content of green house gases. Main GHG are water vapor and CO2, their content in atmosphere define which temperature equilibrium we get. CO2 added by human activities (content was 280ppm before industrial age, now 400ppm) is increasing average Earth temperature. We could well reach +4 or 5°C if we do not strongly reduce CO2 emissions. And +4-5°C is not peanuts, it's the temperature gap between the last ice-age and our times (holocene). Also it's happening very fast, hence the threat for humanity.

    difference between Tromso and Cairo, say, isn't about how close to the sun they are. they are very nearly identical distance to the sun, differing by less than 40 ppm. it's about how much sunlight at what incident angle, the place gets, each day

    We are in an ice age. What we're in is a glacial minimum. If it weren't for Antarctica, winters would be much warmer. When Africa was at the south pole, conifer trees grew there, showing that ice doesn't have to last year-round on the southern pole.

    i believe humans will develop such great understanding of the cycles that we will never again experience ice ages or any other extreme temp ages because humans "can" adjust C02 levels at will once we become 100% renewables.

    Seasons are theoretically more extreme in the Southern Hemisphere because of the amplification of the sun's rays in summer by closest approach to the sun, and their diminishment in winter by being further away. However, the Southern Hemisphere as a much lower land-to-ocean ratio than the Northern Hemisphere, so the greater amount of water buffers the theoretically more extreme seasons.

      Hi, if you are not saved, and would like to be included in the rapture of the church. Believe that Jesus's death on the cross, was enough to pay for ALL your sins , yes ALL ,(past, present and future) That is what the Gospel is about. We are saved by GOD'S amazing grace, through our faith in Jesus's sinless life, death on the cross and resurrection 3 days later . No additional works needed. It is literally that simple.

      @Vivian Brégier The Earth receives 7% more sunlight at perihelion in January than at aphelion in July. That is significant. My point is that if the Southern hemisphere had the same landmass distribution as the Northern hemisphere, it would be much hotter than it is, because the land mass distribution favors the Northern Hemisphere by better than two-to-one, and in summer, land is hotter than water. The Southern Hemisphere gets 7% more intense sunlight in summer than the Northern Hemisphere gets in summer, but the Southern Hemisphere has less than half the landmass of the Northern Hemisphere, so the heat effect of the additional sunlight intensity is negated.

      @Alan Sewell Distance to the sun due to Earth’s eliptical orbit matters slightly (summer in southern hemisphere is still hotter than winter in southern hemisphere, because this effect is still way smaller than inclination of sun rays)
      Distance to the sun due to earth’s axis tilt, that I was commenting because it is what this video presents, is totally negligible !

    • Alan Sewell

      @Vivian Brégier It's about distance too. The Earth has an elliptical orbit that takes it several million miles closer to the Sun on January 5 than it is at its furrtheret distance in July. The distance variation accounts for a 7% difference in solar radiation: At the time of perihelion, Earth is about 91,398,199 miles (147,091,144 kilometers) away from the sun. On average, Earth's distance from the sun is 92,955,807 miles (149,597,870 km). When our planet reaches aphelion in July, it will be 94,507,635 miles (152,095,295 km) away. The fact that the Earth gets 7% more heat during the Southern Hemisphere's summer is offset by the fact that the Southern Hemisphere has more water to absorb the extra heat.

      No, it’s not about distance. It’s about the angle of sun’s rays, which causes them to be spread over a wider area in winter, and the duration of the day. In winter each area gets less power, for a shorter amount of time per day, than during summer.

    When I watch videos like this it really puts human history in perspective. What we call "civilization" is a very recent thing...and likely very temporary. Unless future humans invent new ways to artificially manipulate the seasons and temperature of the earth, this brief period of human prosperity and advanced technology is likely going to come to an end in a few thousand years.

      You do realize that the LIA was a regional event that barely effected the global temperature? As a whole the past 10,000 years have seen earth have a very stable climate.
      Also just because the climate has always changed doesn’t mean co2 can’t be a cause of that change (it has especially so for much of the Earth’s history, so much so co2 has been caked the earth’s thermostat) and it doesn’t mean humans can’t cause it now.
