Earth underwent a massive, rapid melting period after the last global ice age, new study suggests

Yeah. The Younger Dryas event.
Also coincides with a lot of micro diamonds and iridium deposited around the same time.
It was in slight conspiracy space for a while but it’s looking more and more reasonable.
Likely the northern ice shelf during the ice age was hit with a larger comet that broke up and hit earth like a shotgun. Causing a fast melting event.

IIRC, they found a crater (via LIDAR?) in Greenland that could be a candidate for the Younger Dryas impact.

The Younger Dryas was the last glacial period of the current ice age, this link is talking about the last ice age (650mya)

Yeah most just call it the younger dryas event, which was the sudden change at the end of that ice age cycle.

No, Younger Dryas is a 'mini-ice age' that lasted about 1200 years and occured approximately 13,000 years ago.

Do you have a source for that? Not seeing anything using the term Younger Dryas to refer to anything other than the most recent period of glaciation in the current ice age.
Looking into it I did discover that the article is incorrect that the last ice age was 650mya since there have been at least 2 others between the current one and the one they're talking about. I think maybe they meant the last candidate for a snowball earth and phys.org didn't understand the distinction between that and an ice age (the paper itself just calls it the Marinoan snowball Earth and doesn't claim it was the last of anything).

I think maybe you're confused on the difference between a glacial period and an ice age?
We're currently in the same ice age as the Younger Dryas, which was a glacial period (vs the interglacial period we're in now). I was just saying that the link is talking about something about millions of years before any part of the current ice age.
Don't want to argue about the merits of the evidence surrounding the impact hypothesis but whatever you think of it it's still a fringe hypothesis by definition since most mainstream scientists don't accept it (personally I agree that none of the supposed evidence for an impact is terribly convincing).

All of his babbling leads up to "Here we are again, advanced, on the verge of catastrophe that erases our presence for thousands of years!"

What took 10 million years those days could take 10 years today

10 of we’re lucky…cause the longer this lasts (humans plus a rapidly changing world) the more we all, and it is all, of humanity suffers.

Most of the people paying real attention have their bets placed on about 10 years of stability remaining.
Spend em if you got em folks.

I hate to say it, but that's basically what I'm feeling. For a developed, western nation, prices are going to hit points where certain items become basically luxuries beyond most people's grasp. Like no more chocolate, ever, for more than half the population. And for the rest, it's like something you might eat once a year, because you found a good deal on the black market or something.
The coffee collapse as well. That's going to crush capitalism, which requires people to basically be on some sort of stimulant to even keep up with the demands of constant, waking availability at every job. The pharmaceutical companies will spasm with delight as the spike in demand for their designer amphetamines, but even that will become strained, as supply chains break down. If that shipping container sending agricultural goods isn't flowing, other things stop flowing as the res tof the infrastructure becomes neglected and shrinks.
Basically, the horror of collapse is the collapse of globalization, and all its fruits. Which while we may jeer at it, from an intellectual mountain, we're standing on that mountain, able to form such abstract thoughts, specifically because the mountain is made of the universal opulence that we all enjoy, and will watch slowly slip away in the course of the rest of all of our lives. We can be haughty in our thoughts and beliefs because we lived in an age where it was possible to gain access to higher education, because it was physically possible. Fossil fuels allowed us to live in a society where you could pick yourself up, and just go to a university, in much of the world, simply because you were clever enough to make it. But fossil fuels got you there. It kept the grocery store stocked so you could not produce food, and just learn. If you went in a city, and enormous carbon footprint expanded to meet that cities needs as people occupied an area far denser than we ever evolved to occupy. All so you could have such high minded ideas.
It's a big shit sandwich, and we all have to take a bite. I just hope I get to see a few billionaires get lynched or assassinated before my time is up. I'll go to my end watching the end of it all slowly unfold, knowing there was at least some good in us, after all.

You said it better, I'm too tired to care to form a stronger thought.

Agreed

This is how I am starting to see the Phase Change that has now begun. Go back one century and the tempo was (1). Century events occurred every 100 years give or take. Decadal events hit us every 10 years or so. Now everything has sped up 5 to 10 fold. Century events happen every 10-20 years. By 2035 we could be at a 20-30 fold pace. Meanwhile over in climate skeptics, our fellow citizens insist that property insurance rates are only increasing because there is more property, not because the risk profile to that property is higher.
The Drill Baby Drill team is in the process of committing large scale speciecide. They claim to hate taxes, but their children and grandchildren will be paying a large and growing thermal tax because they refuse to pay a carbon/methane tax....

The following submission statement was provided by /u/Portalrules123:
SS: Related to collapse because the changes talked about in this study, while dramatic, took place over 10 million years which was still considered relatively ‘rapid’ given the context of geological time. We are terraforming the Earth over a period of decades, centuries at most, so we can expect very dramatic changes rivalling those seen in the past. It seems that overall the climate system is far more vulnerable to change than the ‘moderate’ science faction believes, and expect this to be realized as climate collapse accelerates.
