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).

G.K. Chesterton suggested that the cave paintings might have been decorations created to delight the children of the tribe who used the cave as a nursery for young children forced to stay indoors through the long, bitter winters.

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. This would in turn promote the Rare Earth hypothesis and Enrico Fermi's paradox would be seen as being more profound.

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 Год назад

Yes, similar to how a solar sail works. It’s the radiation pressure that causes the movement relative to the original object.

@isellcrack3537 Год назад

does this mean that the "tail" can be in the same direction as the comet is moving?

@vlindstrom Год назад

@@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.

@amrcombs Год назад

We call that process that you explained in detail a "tail". So yes, they do have a tail and that is what we see from earth.

@ACE-sx8mo Год назад

@@amrcombs Yes of course. My point was that comets do not normally leave a trail of matter behind them as depicted in the 17:35 mark. Without solar radiation from a nearby star, there is no tail.

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.

Is it possible that polar stratospheric clouds existed during the cryogenic period? The temperature would be right for them, but I don’t know if there was enough water vapor and nitric acid in the atmosphere for stratospheric clouds to appear.

One thing that concerns me is that when the topic comes up everyone seems to gloss over that there is plant life in the permafrost. Plant life... and animal life. The smashed carcasses of mammoths to be exact. With the remnants of their last meals still in their stomachs.

HOTE produces outstanding documentaries. I learn a lot from each one. Btw I think Saturn got its rings during Earth's Mesozoic Era, when an icy moon got too close to the planet and broke apart.(At least that's the current understanding from the Cassini mission.) I like the section at the end about how microorganisms thrived during the icy/ slushy periods.

There would have been murals outside.. And most would have been a status symbol, like a car, or like a decorated house in modern times. Religious use would have been apparent too, as it is now. Not everybody would have been able to paint; only a few. Any cave would be more homely with paintings of plenty of food on the walls. There would have been wooden settlements extending out from the cave mouth. Have we found a stone axe or large wedge? It would be flint and at least six inches of blade; heavy enough to swing and split a branch, just as today.

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.

@noneofyourbizness Год назад

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.

if it's just a matter of albedo, it should be possible to control the cooling and warming by artificially deflecting lights from the poles. Mirrors directed to the sky or white materials covering an extended surface at the North pole would do the trick.

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.

These videos always approach existing themes and ideas from new angles, and its the content of questionining, examination of the latest evidence and the importance of individual contributions to advancing our knowledge that makes them so watchable.

@leppad 3 месяца назад

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.
