    Are you serious? I was just browsing for a video to watch along my meal, refresh and what do I see? An almost 2 hour Astrum video posted a minute ago. Thanks man! Edit: What exactly in my comment makes disappointingly many people assume that I eat for 2 hours straight? You people do comprehend, that a video can be continued being watched after one has finished eating, no?

    My favorite way to go to sleep, gently lullabied by his lilting voice telling us of our future horrors. Yet it’s not nightmare fuel. That’s talent. He’s like the Bob Ross of science.
  • @kswis
    I don't think I've ever learned more about weather in 2 hrs. If not for the all mighty astrum I'd have zoned out. Truly fascinating

    1816 The global "Year without summer (big freeze)" 3°C temperature drop and crop failures. April 1815, volcano Mount Tambora began to violently erupt. Millions of tons of ash, dust, and sulfur dioxide were released into the atmosphere, casting a temporary chill across the planet as it Blocked out the Sunlight for months on end. Documented around the world in literature.

    This is the best summarization of the climate I've seen. It's rare I see the solar cycle discussed to the point of nucleation sites. I wish you had discussed the long-term brightening of our sun (models vary, but scientists estimate the sun was 30% dimmer during the time of the dinosaurs than today), as well as vulcanism. Regardless, this is the most comprehensive video I've seen and I wish more people would see it. I know I'll be sharing it with people.
  • @edwinlipton
    This narrator is so good at speach and oration, "I" actually look forward to learning.
  • @dinopso
    Dear Astrum team I want to congratulate you on this beautiful production of almost two hours on the discussion of global warming. The extensive scientific research that you addressed and delved into is simply brilliant. Bravo !!! I am a Geologist and yes, climate change is scary, but through this documentary, you manage to bring the true and essential substrate necessary for us to understand the relevance and responsibility of our role as human beings within this complex cycle that has governed our planet for more than 4 billion years. Continue to improve knowledge of astronomy and science in general with your videos. Once again, congratulations to everyone on the team and especially to you, Alex McColgan, for the wonderful work leading your Astrum.

  • The more I've learned about our power grid & our climate, the more i realize that modern nuclear energy is our best option. LFTRs, Thorium Reactors, molten salt reactors, etc. Utilizing our advanced technology, Improved engineering & material science. Utilizing our greater understanding of safety & well made designs. We have so much more advanced computer technology & robotics that can be used. It feels like even tho tons of advancement has occurred with engineering designs, safety measures, etc. It still doesn't matter to most people. It's like most people are ingrained with a natural negative response when talking about nuclear energy. It's a bummer because i truly believe that our best option for our future is to start utilizing Modern advanced nuclear energy options in our electrical grid. It's just proving to be challenging to get politicians to get on board.   It will really allow places to be much more energy independent. Less reliant on fossil fuels. They'll have efficient, stable electrical grids and the rest of the grid could experiment with alternative power sources, power desalination plants, etc. We need to heal from the trauma of our past. See & learn that those things only happened solely from Us not understanding what we were doing when it came to nuclear energy at the time. We didn't have advanced enough technology, material science, engineering, safety measures, understanding of how to go about everything, etc. This source of energy will greatly help the world improve towards the future and lowering emissions. More than anything else could, while also providing a very stable electrical grid system. Currently we have alternative energy options but the majority of our grid is powered off of fossil fuels and emission producing sources of energy. We will be so much better going forward commiting to modern advanced nuclear energy options. It's been very irritating that our society has taken this "Change is up to you" approach. It just takes advantage of people's emotions. This climate issue is so much bigger than any one individual. This needs to be an across the board kind of thing. That's the only way we might make the Slightest difference. We've already waited too long. Everyday is a day wasted. A day where we haven't committed to modern nuclear energy options. Where we haven't even started building it. It should be utilized in collaboration with other alternative energy sources all over the place. This power source is the best option to improve our environment & will really help lower our emissions. The only thing holding us back is legislation, fear mongering & past trauma that's affected us from our past failures (which is understandable but I know we can do better now. We've learned so much sense then. We gotta give it a shot. It's such a beneficial energy source when done right) Did they outlaw electricity, oil, natural gas or coal when things went wrong in the early days of those fields? No! They kept going and understood things usually are bumpy and difficult in the beginning and kept going even tho those sources negatively impacted our environment. A huge issue is our government is BLOCKING any sort of progression from happening. Will be lucky to see the slightest projects approved or finished with-in the next 100 years.. It's very annoying to see how much we have gotten in our own way when it comes to improving or advancing certain things. Instead we let fear, money, man made "required legal processes" Stop us from doing anything other than wind, solar, oil, natural gas, damming our rivers, mining for minerals... It's very frustrating because we should be able to use all these options in collaboration. If we actually wanted to improve anything. That's what we need to do and stop letting so much potential get blocked from ever occurring in the first place.. It's really irritating. I wish certain people didn't make this so "complicated and difficult" Why would any reasonable person want to block progression?

    Solar cycles also affect the polar vortex. Solar maximums put more energy into the atmosphere causing increases in the variability of the polar vortexes. At solar minimums the polar vortexes are basically circular. Solar cycles have also been linked to the magnetic connections between the earth and saturn. Magnetic connections between the sun and planets is at least as important as the gravitaional connections. Also affecting the heliosphere is the cyclical connections with galactic influences. Good job. Well put together discusion.

    6:40 FYI at this part(so far in your video) is incorrect. Paradoxically Earth is warmer when it is farther from the Sun. This is due to the seasonal effect of the uneven distribution of land and water between the northern and southern hemispheres. July, when Earth is at its most distant, is also summer for the northern hemisphere. The north has more land which heats faster than water. January, when Earth is closest to the Sun, is summer for the southern hemisphere dominated by oceans which respond more slowly to the increase in the Sun’s energy. The tilt in Earth’s axis produces almost 20 times the effect of the changing distance from the Sun, and the difference in local geography is 2 to 3 times more important than the changing distance. We make our closest approach to the Sun (147.5 million km) in January, that's called perihelion, and we're farthest from the Sun (152.6 million km) in July, that's aphelion. "Averaged over the globe, sunlight falling on Earth in July (aphelion) is indeed about 7% less intense than it is in January (perihelion)." That's the good news. The bad news is it's still hot. "In fact the average temperature of Earth at aphelion is about 4° F (2.3° C) higher than it is at perihelion." Earth is actually warmer when we're farther from the Sun! How can that be? It's because our planet is -in a sense- lopsided. Continents and oceans aren't distributed evenly around the globe. There's more land in the northern hemisphere and more water in the south. During the month of July -near the start of northern summer- the land-crowded northern half of our planet is tilted toward the Sun. "Earth's temperature (averaged over the entire globe) is slightly higher in July because the Sun is shining down on all that land, which heats up rather easily," says Spencer. Solar heating raises the temperature of continents more than water because the heat capacity of land is lower. Bill Patzert, an oceanographer at NASA's Jet Propulsion Laboratory explains: "The temperature of land changes easily, which is what we mean by low heat capacity. Consider the desert: At night the desert is cold, perhaps only 60° F. When the Sun rises in the morning the temperature might jump to 100° F or more." Such mercurial behavior is characteristic of materials like rocks and soil with little thermal inertia. It doesn't take much sunlight to substantially elevate their temperature. "On the other hand," says Patzert, "oceans have a tremendous heat capacity. They tend to keep [the energy] they capture and are very stingy about giving it back." This quality moderates the temperature swings of ocean environments. "Let's say you went sailing off Malibu Beach at noon," says Patzert. "The offshore temperature might be 75° F -- pretty pleasant!" What happens after sunset? "The temperature drops, but only a few degrees because the thermal inertia of the ocean is so high." All this explains why July is our planet's warmest month: Northern continents baked by the aphelion Sun elevate the average temperature of the entire globe. Six months later, in January, the situation is reversed as our planet presents its water-dominated hemisphere to the Sun. "We're closer to the Sun in January," says Spencer, "but the extra sunlight gets spread throughout the oceans." Southern summer in January (perihelion) is therefore cooler than northern summer in July (aphelion). Strange but true! Another notable difference between summers in the two hemispheres is their duration," adds Lebo. According to Kepler's 2nd Law, planets move more slowly at aphelion than they do at perihelion. As a result, Northern summer on Earth is 2 to 3 days longer than southern summer -- which gives the Sun even more time to bake the northern continents.[1] The fact that people living in the northern hemisphere are warmer when near aphelion is primarily due to the seasons, which are caused by the tilt of our axis. The fact that the Earth as a whole is also warmer when near aphelion is due to the difference in geography between the two hemispheres (mostly water in southern hemisphere, water and land in the northern hemisphere). In numerical terms, the tilt of our axis produces almost 20 times the effect of our changing distance from the Sun, and the difference in local geography is 2 to 3 times more important than the changing distance.

    I just love how Astrum pronounces ”earth”. It’s like ”örth”, the sound that the Swedish letter ö makes, if a bit more nasal.
  • I live in Rio Grande do Sul, Brazil, we are experiencing an extreme Flood even bigger than the one in Peru like you showed, and it was partially because of the El Niño as well, the power of the elements in our earth are insurmoutable, we can't really predict or overcome them right now, and yet we influence it so much
  • Great video, thank you! I knew about the existence of many of these cycles, but it is nice to see them all compiled in one work and also described in such depth.

  • Fascinating how you can relate the Milankovitch cycle with the 4 yugas.
  • @staff97
    i literally go to sleep to these. so interesting but also relaxing. it keeps my mind occupied
  • @MyKharli
    So in 10 or so years a spring tide with an onshore storm surge will deffo break records in loads of places .
  • @mariz2361
    You're a brave man!!! I'm gonna have to watch this again in a few days and see what comments you get........
  • @lindawalker8949
    The approximate 50 actively erupting volcanoes spewing CO2 and SO2 into the air certainly helps with greenhouse gases. Tonga's volcano sent steam amounting to 63000 olympic size pools int the Stratosphere. I wonder how our footprint measures up.
