What glaciers left behind in the post-ice age in Scandinavia

At the end of the last ice age, there was a time when glaciers reached their maximum. This period is called the Last Glacial Maximum, or LGM. After the LGM, glaciers melt over thousands of years. As a result, many changes have taken place in Fennoscandia.

This episode introduces the Fennoscandia ice sheet's thawing and the first Scandinavians' migration. It also introduces the uplift, the tsunami, and the formation of lakes caused by deglaciation.

I am living in the Kvarken (Quark) area and during my life time the land has risen more than half a meter or 20 inches. Combined with the sedimentation around the coast it is a quite noticeable change. Close to where I was born there was a shallow bay which jow is dry grassland. The high coast area on the Swedish side is quite spectacular and the the De Geer moraines in the Vasa Region on the Finnish side are unique in the world. No worries of rising sea levels around here. Now I also have a 9*4 meter ice age boulder in my yard😃.

Very interesting explanation for an Japanese geologist to become familiar about Holocene ice age time geohistory of the Fennoscandia area. Thank you so much!

what Ikea, the highest democracy and forested land has to do with post-ice age?

[oimikaborsaz]

How much of what was presented in the video was caused by climate change due to human activity, protohuman camp fires, combustion engines and factory emissions? Or maybe the climate is supposed to change regardless of what we do?

The teachers I told you before and now we are very grateful to competent channels help tissim will send the quality of our classes Thank you very much and congratulations

Hey great video, from a Swede!:) Just a correction, it's cm^2, 0, 9 grammes per centimeter cubed, not meter cubed:)

Tack för all denna underbara information. Behövs de kommande decenniumen <3

Great introduction on the subject.
I was very happy about you mentioning the Population genomics of Mesolithic Scandinavia study.
Since i've been meaning to look it up.
Many thanks!

Me as a scandinavian since birth found this video very informative
so thank you .

[SixStingsDarko]

Excellent! Much appreciated! Definitely subscribed!

[kristofferhellstrom]

Crazy interesting video! Haven't seen anything like it before. The robot voice though :/

[hollywoodpotato]

Thanks for incorporating Ice Age geography and it’s relation to migration. Well done

[AreHan]

Fantastic! I have never seen a video so packed with super interesting information! It really helped my understand this part of the world today.
Greetings from Norway

Finland, the land of a thousand lakes

[andreasalm]

Excellent!

Would be even better with a human voice, though. 
And why not?
Even me with my Swedish way of talking would do it instead and it could have been worth it and I'm sure there are countless of others who would be able to do it so much better still, so why the fuck not?

Tech is awesome and everything. Trying out stuff like this is what in the future will lead to succeeding in telling a story like this one. Without the little glitches.

Anyway, excellent!

Huge boulders,
When walking in the forest I used to wonder how they ended up there, and so got the answer that the ice somehow cracked/shaped and moved them.

I imagine people who wouldn't have had those explanations made up up their own..

Good way to show ppl what happened back then...Thanks.

When you're talking about the weight of ice you show the term grams per cubic centimeter, but your audio says grams per cubic meter. A thousandfold increase makes a big difference.

Your video is actually going to be helpful in my genealogical research! I am just about certain my maternal line is less German, and more Finnoscandian, than I'd have ever imagined! I will look north, in my research, on my maternal line. I'm U5b1.
