The people behind this research have a rather interesting Twitter account on which they document many of their finds and glacial archeology in general.
Two standard deviations from the mean is an outlier.
penteract 1217 days ago [-]
It's an outlier if you assume nothing's changing, but there are better ways to say that sea ice is generally shrinking than by pointing out that the current year is an outlier.
I meant that it doesn't look like an outlier if you assume arctic sea ice is decreasing (linearly?) over time (it does look like an outlier even there if you focus on October 24th).

Nothing to be alarmed about. We are but passengers on this great planet. 10,000 years is nothing.
Ekaros 1217 days ago [-]
The planet will still be here in immediate future. Ofc in short term it will be eventually gone due to sun engulfing it.

Just an exponential function showing its true colors, not sure what is alarming here. /s
JoeAltmaier 1217 days ago [-]
Hasn't done this for 6000 years. Its doing things like this everywhere. So while one data point can be thought of as 'normal' or 'just how an exponential function works', a global phenomenon is damning. We're in a very fast, very abrupt warming time. Nothing like any historical period. Not explainable as normal variation.

Sweet giant plants and firestorms that cover the planet making more coal for future generations.
TeMPOraL 1217 days ago [-]
They don't, though; firestorms are the opposite of what you want for coal generation.
jamiek88 1217 days ago [-]
Also coal was made in the Carboniferous when there were no wood eating microbes. The lack of creatures digesting wood is gave us coal.
So...no. No silver lining. Or at least not that one.
Tuna-Fish 1217 days ago [-]
Most of our coal reserves were deposited as charcoal, after a firestorm.

This PDF [0] has vg shots of several arrows. (See fig. 4) (I'm not surprised at straight shafts from 700CE. But F166 (fig. 4b) from 3980-3830calBP is birch (Table 1) - and surprisingly regular.)

This made me think of a book plot I'd like read: melting ice reveals a sign "we've been in this situation, at this point you've got 5 years to revert the climate trend or die".
pilsetnieks 1217 days ago [-]
To me, it rather reminds of the (actually existing) Japanese tsunami stones - the stones littering the coasts of Japan bearing inscriptions warning not to build homes below the point. The Fukushima Daiichi plant was built below that point, in fact it was built on the beachfront.
-Not only was the plant built more or less on the seafront, the sheds housing the backup generators were quite literally built on the quay stones.
In hindsight (which, after all, is 20/20), it would have made sense to keep a set of backup generators on the top of the reactor building, just in case a tsunami came a-knocking.

Wouldn't this finding imply the reverse situation - we've been at this level of climate before during a -cooling- time (hence ice) and we're now going through a reversal of that cooling?
viraptor 1217 days ago [-]
It depends how optimistic you are. It could be a message from a civilisation wiped out ages ago, because they knew at what point they crossed the line when the changes were irreversible. (ignore the continent drift and the placement of the sign for a bit :) ) Devices left behind kept working for some time, speeding up the recovery enough that we can't see that period clearly in any usual natural markers.
bioinformatics 1217 days ago [-]
Nah, it's not optimism, it's intelligence, really.
Yes, it's definitely a message from peoples of olden ages.
During the holocene, (last 10,000 years, ie after the ice age) Northern Europe has seen much warmer temperatures than the average of last century. Finland had oak forests in the stone age five thousand years ago. And there were much colder periods than now in between etc. Currently there's a lot of old oaks only in the warmest most favorable locations and forests are mostly pine. After all they take centuries to grow. But oak is again spreading.
Oh, yeah, we have a lot of them in the Elbe. (CZ).
chrisco255 1217 days ago [-]
How do you suppose the Vikings reverted the climate during the Medieval Warm Period?
Interestingly, Norse Mythology centers around Frost Giants signalling the end of the world. They feared the ice returning.
Why do you think that is?
sebcat 1217 days ago [-]
Fimbulvinter (a long winter) was a sign of Ragnarök. Ice giants was not a sign.
chrisco255 1217 days ago [-]
Fair enough. Point still stands. The Norse feared long and continuous winter. Not warming. Why?
PeterisP 1217 days ago [-]
Because the area is currently colder than average or optimal for human habitation and agriculture.
Colder climates make Scandinavian peninsula uninhabitable (e.g. as it was during Weichselian glaciation) and local warming would likely even be helpful for the long-term habitability and agriculture of that particular region (unlike the much more populated areas in warmer climates), the costs and risks for Nordic countries mainly come from the change as such, requiring adaptation.
The Norse people who were living in the northern parts of modern Norway would probably prefer if these lands had the climate of current Oslo area or Denmark, not fear that.
roywiggins 1217 days ago [-]
Quite possibly because they had actually experienced what happens when the summer doesn't come.
Isn't it obvious? Winters in Scandinavia are dark and cold and nothing grows. A winter lasting multiple years would lead to starvation, so basically the end of the world. Especially if the sun and moon was eaten by a wolf.
But according to Völuspá, after the Fimbul winter there will be a big battle and the fire giant Surt will set the world on fire with his flaming sword. So you get both ice and fire!
Ha, you made me realise that it would be basically a message for a Seldon Crisis.

It's hard to imagine living in a world where the same ground produces food hunted with bow and arrow for 5200 years.
I mean... what constitutes a generation gap in that world?
WalterBright 1217 days ago [-]
More advanced weapons require a lot of diverse foundational technologies which took a very long time to develop, simply because of a lack of writing, a lack of even the concept of those technologies, a lack of labor specialization, and a lack of the concept of an organized development process.

z3t4 1217 days ago [-]
Reindeer was domesticated. So they didn't need to hunt them.
Kind of makes you want to hang out along the edge of glaciers to see the big reveal. Pretty interesting find.
The arrow in the picture appears to be metal so not stone age. And the question of why so many in that spot? Did something in the ice collect them there from all over? Or was their a seasonal hunting ground where these guys hunted?
Sadly what I see in hunting spots around the bay are discarded plastic shotgun shell hulls[1]. Sadly I think those things will last for a very long time.
[1] Yes, I pick them up when I find them and hike them out but clearly not everyone does.

> The researchers have also found reindeer antlers and bones and other biological matter but have been surprised by how few of them have been revealed as the ice melts.
Sites like this can be a "kill zone" where animals tend to naturally gather like say a watering hole or a cluster of exceptionally tempting edible plants. No need to create a lure or decoys, just wait for them to come.
Lack of bones may indicate that kills were moved before they were dissected.

Reindeer do gather on snow patches in summer/early autumn to avoid insects.

Is it normal to hide these archaeological sites?
Just seemed weird to not publicize the finding. I suppose it’s better to have tourists and locals come visiting.

Not if they will move / not report interesting items, or stomp over ground you want to see undisturbed for some time.
Just look how quickly the recent monolith discovery changed into a tourist attraction and got popular on the internet.
stan_rogers 1217 days ago [-]
Yes, it is normal - and that's because sites quickly become useless for archaeology when the souvenir-hunters and traders in artifacts come a-calling. It's not just about what is there, but where everything is in relation to everything else.
JoeAltmaier 1217 days ago [-]
Still, melting ice can render ephemeral objects unrecognizable in days. Even if 'pot-hunters' moved in, they would at least preserve something. As it is, perhaps millions of artifacts are decaying to be lost forever? That's not good archaeology either. I'm of two minds on this.
AlotOfReading 1217 days ago [-]
Yes, it's typical. For one, you don't want people disturbing sensitive sites that may need to be revisited periodically. Things that have the allure of value tend to make otherwise reasonable people greedy and come sniffing around for things to loot. It's not hidden from anyone with credentials or the government, just the general public.

Absolutely not. Humanity is not trust worthy. It’s going to be a couple of days before Instagram influencers descend on the site and destroy it.

It reminds me that this happens every year in some parts of the world, with loose items and such found in the spring.
Therefore, I imagine it happened every year in that part of Norway for the years leading up to this very long freeze that's now thawing.

A block of what appears to be encoded language is found in the DNA of virtually all organisms. It includes a primer with a key to decoding it.
After years and years of work by the world’s greatest cryptographers, the message is deciphered. It reads:
“Danger! Extremely hazardous self-replicating agents! For hazardous waste cleanup use only. In case of spill or uncontrolled replication, contact...”
I wonder what kind of hazardous waste life was meant to clean up..? And what was the contact address!??
