Hello, really like your videos. You manage to make your purely prosaic descriptions of these ancient geological events almost feel like poetry at times, which is really appreciated. I'll keep it short, but an interesting sidenote. Acc. to the report at the end of this comment, the Earth almost entered a snowball-state at the start of the Permian at 299 mya. The carbondioxide in the atmosphere had been drawn down due to the vegetation in the Carboniferous swamps, I think, and the global average temperature was at ca. 1.4 degrees C (the punctuation is not a mistake).

Never mind about Earth sitting in the Goldilocks Zone in it's orbit around the Sun, it would seem to be more like a Goldilocks Knife Edge tipping between Snowball Earth and a runaway Greenhouse Earth.

To clear up a common misconception about comets at 17:35, comets do not actually leave a "tail" behind them as they travel. In the vacuum of space there is no atmospheric drag. When astronauts conduct a space walk, their ship does not zoom ahead and leave them trailing behind. Solar radiation from a nearby star sublimates (defrosts) the comet's frozen surface, and those sublimating particles are pushed in the same direction as the solar radiation. So the direction of the tail is entirely independent of the comet's trajectory.
@Sniperboy5551 Рік тому
Yes, similar to how a solar sail works. It’s the radiation pressure that causes the movement relative to the original object.
@isellcrack3537 Рік тому
does this mean that the "tail" can be in the same direction as the comet is moving?
@vlindstrom Рік тому
@@isellcrack3537 yes, the tail always points away from the star, so when the comet is travelling away from the star, the tail would be pointing in roughly the same direction, although since the orbits are elliptical, probably not exactly the same direction.

The flaw in Budyko's model is that there is no hydrologic cycle. He can't be blamed for this. He had 1969 computer technology to work with, and he had to make many simplifications. What would really have happened with a 1.6% reduction of the solar constant is that some areas would remain ice-free because sublimation exceeded snowfall and deposition, so even with low temperatures, areas of the earth would have low albedo, and this would be the reversal mechanism once solar radiation increased again.

Here we go again. 1) The Neoproterozoic is an era not a period. 2) The Huronian is a Supergroup of rocks, not a geologic time. 3) It also was not glaciated for 300 million years! That's not even in debate. I know you all got that from a Wikipedia article, which was so wrong. I corrected it and your all still parroting it. Yes. The Huronian contains diamictite. Bit it's about 11% of the total rock. The vast majority is a normal passive margin sequence. Most formations like the Lorrain, Serpent, and Bar River Formations, indicate a warm environment. 4) The GOE didn't even happen until until more than 100 million years into the deposition of the Huronian. It's actually post glacial. Yes. I study these rocks. I am a geologist. I've even done videos on these rocks in Ontario.

according to the MJA (medical journal of Australia) the arctic explorer did NOT die from eating dog liver. From the article: During the Australasian Antarctic Expedition of 1911-1914, Douglas Mawson and two companions, Belgrave Ninnis and Xavier Mertz, undertook an ill-fated mapping journey. Ninnis died when he fell down a crevasse, together with the sledge carrying most of their food supplies, and later Mertz became ill and died. Only Mawson returned. In 1969, Cleland and Southcott proposed that Mertz died of vitamin A toxicity and Mawson suffered from the effects of hypervitaminosis A because, with little food left, they were forced to eat their surviving dogs, including the liver. This hypothesis was supported by Shearman in 1978. After re-evaluating this hypothesis, I propose that Mawson and Mertz suffered from the effects of severe food deprivation, not from hypervitaminosis A, and that Mertz died as he was unable to tolerate the change from his usual vegetarian diet to a diet of mainly dog meat. I also suggest that Mertz’s condition was aggravated by the psychological stress of being forced to eat the dogs he had cared for for 18 months.

How did they light up those halls to see to paint and draw? I saw no torch exhaust contamination on the ceilings,walls,how did they do it. Unless I'm completely wrong on that,how did they see? So I'm completely taken on how they did it visually,as an artist. The work is not only informative but so very beautiful. What vibrant intelligent people they were to even survive. And then leave a treasure of expression older than modern civilizations.

@davecook3138 Рік тому
Another brilliant video, thank you. Something not mentioned in the video, but may have had an effect is that the moon would have been closer during snowball earth. That would have meant higher tides and more likelihood of the ice surface breaking up allowing the microbes to 'breathe'. This effect would have much more pronounced during the earlier snowball earths.

Surely the waters are all frozen and therefore no tides?
@davecook3138 Рік тому
@@russellhaikney3809 Not at all. The land is also affected by the tides. Land rises and falls about 1cm, compared with the oceans up to 10 metres. If there was any water under the ice, and I'm sure there would have been, it would have warped the ice on the surface, causing cracks and movement.

Good point. As it too is covered by an ice sheet that (very likely) sits atop an ocean of liquid water , the theories and discoveries emanating from 'snowball Earth' have led to present day Europa (a moon of Jupiter) becoming of particular interest to Astrobiologists, who apparently view her as the most promising place in the solar system to find present day life beyond Earth.

Fantastic presentation; our planet never seems to stop in one place or another, ever-churning, agglutinating life, one way or another, being by itself, a conveyor, inducing growth and survival. Brilliantly it implies a certain "chaotic elegance" that in the end, propitiates observation of the clear and coherent system seemingly paradoxical to less discerning eyes.

We don’t know enough about how the sun cycles work, but one thing is certain; the sun is the biggest heat/photonics source. The effect of human pollution on global warming seems greatly exaggerated. This same logic would suggest that humans caused the last ice age by NOT creating enough green house gases.

@leppad 3 місяці тому
So I sometimes wonder about so-called positive or negative feedback. Specifically, my brain seizes up when I think how throwing massive volcanic ash into the atmosphere might block sunlight and cause a freezing feedback loop BUT, ash falling onto snow turns it black and absorbs heat causing a heating feedback loop. How can one determine how this actually might work? What fine line between the two leads one process to dominate over the other? The only thing I can think of to resolve the issue is a variance of the solar output. Solar output is the only mechanism not dependent on anything on the surface of the Earth. By solar variance I mean either increased or decreased solar output or blocking of the solar wind because our solar system drifts through an interstellar dust cloud. The solar wind would eventually clear out the dust but not fast enough to compensate drifting through a large enough interstellar dust cloud.
