So you can point me out at the explanation of the ice period
happened 20-10 thousand years ago?
No, I can't.
Siberian volcanoes, wasn't it. It's a notion that just bubbled to
the surface brain nodules.
This is what I almost half-remembered...

-----Beginning of the citation-----
Analysis of the grains also shows that the impact was most likely made
by an iron meteorite more than 1km wide. It would have occurred during
the Pleistocene, between about 12,000 and 3m years ago.
----- The end of the citation -----
The crater age is very obscure.
Although many scientists have been searching for a long time for a catastrophic event that happened about 12000 years ago.

Please note the warning comments from the TEDx people. I normally
use the speaker's documentaries as an opportunity to feast on
popcorn, and then fall into a food-induced coma (i.e. a sleeping
pill thing). This one had me fully awake and attentive. Sometimes
amateurs get somethings correct, by accident.
I warn you to accept its evidence, perhaps, and recommend this one
to you for a one-time look (I have a local copy of the shorter
version in my library stash).
East Siberia permafrost is as deep as 1.5 kilometers(!). If we count
how much time is needed to froze the soil so deep we will get millions
of years. BTW, permafrost could not be deeper than 1.5 km because
there is a natural Earth heat deep inside and permafrost melted.
Since then the ocean waters have been becoming warmer and warmer. As
the indicator of the process, every thousand of years the sea level increases approximately by 1 meters. And we will see this process for
a long, long time. It means that a natural temperature for the Earth
is higher than we have now. And finally we will arrive to this temperature.
In a way it's comforting to see those figures. This town's height is
just under 9 meters.

That's plenty, I'm at -3... ;)

Do you have a continual sore neck to deal with? :-P

I did not know the depth factor. I've seen video of defrosting
Siberian permafrost and also Alaskan/Canadian permafrost that have
alarmed me. The footage seemed to target 'creek' sites where none
should be, and at those places the sides are approxiamtely 30-50
meters deep to meet the outflowing waters. If it wasn't for the
science assistants actually in the creeks, it would otherwise be
difficult to judge the depth of the banks.
Unfortunately, the permafrost melt is a double-hit with reports of
the melted biomass releasing greenhouse gases more harmful than carbon-dioxide, along with the release of 'fresh' water to water
systems, and into the oceans. Nasty. And I have not seen reports of
any permafrost being renewed. Most perturbing.

other girl is already in an ideal place, except for the pollution
factor (can't win).
After all people can build floating cities. ;-)

Man-made floating things... boats & ships tend to sink a lot, historically. Wouldn't it be better to live in submarine cities?
They can't sink any further. ;-)
You mean a submarine cannot sink? What they do, in English, when water rushes inside? ;-)
I think floating things safer, especially when they consists of
thousands of watertight compartments. If I design such a town I would
made it from big laced steel platforms, and every platform is
surrounded by thousands of watertight cisterns. Every cistern has a limited time service and can be replaced.

Ah, a diving boat. Yes. My apologies. I used the word in its
literal sense: under (sub) + sea (marine). On reflection, I should
have avoided any confusion and said "under sea"... cities. I was
naughty,

Mmm... that sounds familiar. Is that how bridge foundations are
formed?
