[@vensroofcat6415]

I have a problem with that runaway reflectivity argument. Large parts of Canada and Russia are fully snow covered for part of the year. While also having warm enough summers. In continental climate further from shores in particular. One doesn't stop other from happening. Vapor condenses very quickly as the temperature drops. And 1km³ dust - is that really that much distributed around the Earth?

[@markmcd2780]

I'll give you another question. How can polar ice & snow have any significant effect on albedo? The angle of reflectivity or refraction for water is ~71° so light hitting at anything lower angle than that will simply bounce off. not contributing to warming at all. (or very little) So all that really matters is albedo where light comes in at lower angles. Which begs the question - how did the 'runaway' happen until ice & snow got down into lower latitudes?

[@vensroofcat6415]

@@markmcd2780 Yeah... no idea. The more energy Earth receives, the more it irradiates back. In the space there's only one cooling solution and the Earth already uses it. We have certain balance here. Sure, albedo does change things a bit and so does dust and greenhouse effect. Also all that is very tricky non linear math. And when it's simplified, it isn't accurate anymore. What I was personally more curious about is whether 1km³ of dust is a serious issue at the scale. Because water vapor is of minute value here considering dew point and us talking cooling not heating? Also water vapor is considered having greenhouse effect afaik? Not a cooling one. Cloudy winter is so much warmer than the one with clear skies. Also nights in the desert - freezing. So - at first it got very hot (impact energy, water vapor, dust), somehow didn't runaway to Venus and then somehow got very cold and covered everything in snow creating albedo and runaway to Mars. Not trying to mock the topic, climate is important. But I'm not sure it's completely thought thru. Setting significant part of Antarctic ice free and sending into ocean where it's forced to melt consuming energy could have a lot colder effect. But then is that possible at all?

Methane and the byproducts of burning fossil fuels don't shield the planet from solar radiation to any significant degree. This is evidenced by the fact that the lower atmosphere is continuing to warm, while the temperature of the upper atmosphere remains bone chillingly cold and stable. If enough fresh melt water from the north polar regions is dumped into the north Atlantic over a short period of time, it will disrupt the thermohaline circulation, or Atlantic conveyor belt as it is sometimes called. The entire thermohaline circulation system is about 40,000 miles long and meanders throughout the oceans of the planet like one continuous very long river. A disruption in the north Atlantic might cause it to change it's course regionally, or it might stop completely for a time. We can't be sure. It is known that any interruption in the flow of warm equatorial water into the north Atlantic will trigger dire environmental consequences for the people living in the northern hemisphere, and especially Europe in the early stages.

@leadbreastplate7496 I had 2 years of college, then had 4 children! Im 71 and still learning! 😊

[@leadbreastplate7496]

@MyraSeavy ok. Classes in what? Having children doesn't teach you about geology. Physical chemistry. Math. Besides perhaps keeping track of how many you have had,-)

[@MyraSeavy]

@leadbreastplate7496 Well that's what amazes me! I wasn't able to continue my schooling! But I still enjoy learning! 😊🎄

Must have been another crossing from Nibiru

after this impact, Africa is covered with sand, and the first floors of old houses are covered with a cultural layer ))

It would be interesting to know if the Eltanin event coincided with a magnetic excursion event...

[@leadbreastplate7496]

@@JonnyCobra nope and no. Your talking about geological events. It's not like ohh Christmas falls on Thanksgiving... Thousands and hundreds of thousands of years... Not coincidentally relevant

"Antenna" does not look very much like what it was identified to be.

Im gonna make you strong says the ice age

[@mahbriggs]

Probably just a coincidence! A little hard to explain the Ice age cycles based on an one time impact!

[@HeathenHammer80]

Our planet still has ice caps and glaciers. We are technically still in an ice age. There have been times when the planet has been devoid of ice.

impacts? what haven't they done for us?

what about repeating freezing? Europe was frozen and thawed at least 4 times

[@robertmoye7565]

The video is interesting but possibly premature. A review of the sources that you list appears to suggest that this theory is in it's early stages of investigation and interpretation with a lot of uncertainty. Also, the Pleistocene glacial epoch started around 2.58 Ma, not 2.5 Ma.

[@justingibbons9011]

This is the thing I don't like about alot of these studies done with the help of computer models.... when they plug in info... don't get the result the expect... then modify the simulation till they get the data that most resembles their original hypothesis. These computer models depend on data being input... perfect set up.for bias...

[@littlefish9305]

did you say an ocean crater has never been found. Burckle crater.

[@karihamalainen9622]

And impact place is very strange place in geology perspective. Look Google Earth map about area.

[@karihamalainen9622]

Very strange "flowing" plate structure.

it could have bulged the planet, it definitely moved it in it's orbit, seems fine, an alien species that can manipulate quantum particles and entanglement would appear as magic, if we could percieve them at all without "help"

We are all a chemical equal and opposite reaction to our chemical environment. So do you think that maybe we were evolved to warm the climate up eventually ending the ice age kinda in the same way waterbears ended snowball earth by adding peroxide to the sea

Hello wonderful unknown asteroid.
