- This is a physics-based simulation of many 1000s of years of accumulation, flow and melting of arctic and antarctic ice sheets during the last ice age. Both floating and grounded ice conditions are included.

i don't think i've ever fully understood ice sheets and glaciers until i watched this video. they truly are just gigantic, semiliquid piles of compacted snow flowing over the landscape
Amazing videos :) Congratulations !!! I am a geologist myself and I specialized the Pleistocene ice age for a while. I think your videos have the potential be great educational tools - but for example this one about the ice age - if you'd like I can help you to make it even more accurate. If you want I can send you some of the latest research that shows what the European (Scandinavian) ice sheet must have looked like according to geological evidence. I say this because the Scandinavian ice sheet didn't go that far south as far as I know - it stopped somewhere in the North of Germany roughly, it didn't reach the Alps. In any case thank you for your videos !!!
Keep up the great work you're doing !
Most ice and snow evaporates a great deal more than it melting due to temperatures. Its why you see ice cubes in a freezer shrink and disappear. Cloud cover, sunlight and winds plays a much larger role than temperatures do. Milankovitch cycles alone won't cause an ice age. You need dust to block the sunlight out.
The Earth was a giant frozen ball of ice and snow for about a million years at one point due to there being a huge dust cloud between the Sun and Earth.
Yes we only need to go back to 1815-1816 to see what foreign particles in the atmosphere can do. Also it's how big piles of plowed snow like in parking lots can remain well into spring and sometimes even summer temperatures.
I find your videos fascinating. Have you considered doing a projection of what might happen with the re-distribution of ice-weight if/when Antarctica, and the Arctic ice melts? We know the seas will be higher, but what about the change in weight & pressure on various tectonic plates? Will it speed up the movement of the plates, slow it down, cause more volcanos? I suppose the effects would be too complicated to really accurately predict, but it would be interesting to see 'ballpark' estimates.
Little Ice Age may happened in some centuries in past
To get there lots of rain and wind to be ,i suggest that we have to go south.
One factor that makes seaice freeze/melt change temperature is pH, if you lower pH the water freezes at a higher temperature than-2C/28.4F.
It's a big deal, we dissolve zooplankton 10-times faster than the PETM flood_basalt extinction today.
Ymmv 🙈
Good thing to have an idea about because ours is overdue.
Tell it the starving icebears!!!! They will be glad!!
Why does the Cordilleran Ice Sheet not appear?
The Cordilleran Ice Sheet is a fiction of the imagination - it's not based in reality - it was a theory that was proven absurd by hundreds of historic documents, written in over a dozen languages from all across our Earth, that tell us the true cause of the water erosion.
@@johnperic6860 Since hundreds of historic documents tell us the timeline for the mountains and glaciers of Alaska, and thousands of other mountains and glaciers across our Earth, we know that geologists and glaciologists are wrong - we also know the timeline from volcanologists is wrong - if you don't want to do the research to see the evidence, if you prefer to regurgitate the idiotic vomit from those imbeciles that graduated with a C average from low level institutions, you are free to believe in their "theories". The true timeline for our Earth and her cataclysms is a shockingly short span of time.
@@johnperic6860 No, are you seriously this unintelligent? You cling to "theories" as you claim "Wisconsinian glaciation ... " "7,000 years." If you enjoy being STUPID, knock yourself out. Giant glaciers covered North America - two miles high - is that what you think? Because that's the THEORY that you were told by idiots? So the glaciers melted and the rapid run off just left billions of seashells sitting there on the ground? That's what you think?
Our ancestors tell us that the ice ages are fiction... giant glaciers did NOT melt away and leave billions of seashells on the ground. If that's what you want to believe, you go ahead and continue to be an idiot.
What you claim is "geological evidence" is of WATER EROSION, right? And then you and your unintelligent fake science gods ASSUME the water erosion is from giant glaciers melting away?
If you want to know the true history of our Earth, do the decades of research that I did and if you're as intelligent as you think you are, maybe you will be able to understand what hundreds of independent historic records are telling us.
If you want to watch my video about the Supervolcanoes in North America ... or my video that explains where our ocean waters came from, that might be a good start for you childish mind.
