he Trump administration informed some members of Congress last year that Mr. Stemberger was most likely arrested after ICE shared information with foreign authorities through Operation Cocoon, according to correspondence reviewed by The New York Times.The correspondence suggests U.S. authorities became aware of Mr. Stemberger’s plans before he left, something Vic Stemberger believes amounted to a missed opportunity to save his father. John Eisert, the assistant director of investigative programs for Homeland Security Investigations, a branch of ICE, said the agency generally became aware of such plans when it picked up on irregular travel, but declined to comment on Mr. Stemberger's case.

Investigators from the Southern District of New York and the Drug and Enforcement Administration, in part hoping to lighten Mr. Stemberger’s sentence, told Spanish authorities in October 2019 that he appeared to have been “pressured, cajoled and subjected to a variety of deceptive and manipulative strategies to induce him to believe that he would receive millions of dollars in inheritance funds.”

J. Bryon Martin, a 77-year-old retired pastor from Maine, spent nearly a year in jail in Spain after authorities found more than three pounds of cocaine hidden in an envelope he picked up in South America. He said a woman he fell in love with online had asked him to pick up the package and bring it to her.Senator Susan Collins, Republican of Maine, pushed the State Department to work with Spanish authorities to secure Mr. Martin’s release on humanitarian grounds in 2016.

Mr. Wiegner said narcotics organizations used to recruit young people vacationing in South America but had turned to less obvious targets. “You probably wouldn’t suspect a grandmother or grandfather of carrying 25 kilos of cocaine,” he said. “If you have a 25-year-old European surfer, it might raise a bit more suspicion.”

In his email exchanges with the scammers, Mr. Stemberger occasionally expressed concern that he was entering a fraudulent agreement, a finding U.S. investigators highlighted to Spanish authorities when arguing that Mr. Stemberger thought he was pursuing a legal business opportunity.

One of the oldest genomes studied came from a thigh bone discovered in Goyet Cave in Belgium and given the unwieldy name GoyetQ116-1. Radiocarbon dating pegs the Goyet individual at some 35,000 years old,

Around 1,000 years after the Goyet individual was found, a new culture swept through Europe: the Gravettians. Analysis of genetic material from the time shows that art and artifacts weren't the only things changing. The Gravettians' DNA was significantly different from their Aurignacian predecessors, suggesting that they were a completely separate lineage.

Goyet guy's descendants retreated to the Iberian Peninsula (modern day Spain and Portugal) and waited for their time to come again.

It did, some 15,000 years later. Probably spurred by climate changes as glaciers began to recede, this dormant lineage expanded back into the rest of Europe, bearing a new culture known as Magdalenian.

Not long after that, their genomes started to look like those of people from the Middle East and the Caucasus, suggesting that new arrivals from the southeast were mingling with — and in some cases supplanting — the existing population.

This was a surprise, because researchers used to think that transition happened much later, when Turkish farmers introduced agriculture to Europe some 8,500 years ago.

The genetic analysis allowed researchers to trace the inexorable decline of Neanderthal DNA, which was two to three times more prominent in early human genomes than it is in modern-day ones. This supports theories that early humans interbred with Neanderthals, but that their DNA was toxic to us and gradually weeded out by natural selection over the course of millennia.

This latest finding may not surprise most climate scientists, who suspect that the planet is as hot now as it’s ever been in at least the past 125,000 years

this study—and work from other scholars—suggests that the Little Ice Age wasn’t global at all, and mostly lowered temperatures in western Europe and parts of North America.

What makes those older eras different from modern warming is coherence—that climate change is happening today just about everywhere at the same time. “That coherence cannot be explained by the natural variability of the climate system,” Steiger said. And it does not characterize any previous era.

No matter how fierce play may look on the playground or in the social scrimmage of the school day, the more grueling competition is the one your child faces each day to measure up in her peer group. At around age eight, children start to compare themselves to each other in more competitive ways.

media and much of life online introduce an adult context for a child’s self-assessment. The behaviors they see there that set the bar for cool, cute, bold, and daring come from the wrong age and life stage. The mix suddenly includes adolescents and adults, media coverage of fame-addled celebrities and jaded politicians, teen magazines, and Victoria’s Secret at the mall and in the mail.

As the inner critic grows, parents become indispensable as the voice of the inner ally, the voice that helps balance a child’

innermost sense of himself

Day by day, kids need time to process their experiences intellectually and emotionally, to integrate new information with their existing body of knowledge and experience. They need time to consolidate it all so that it has meaning and relevance for them. Ideally, they do that with their parents and in the context of family and community.

Kids don’t get home from school anymore; they bring school—and an even larger online community—home with them.

t in the ways that matter most, speed derails the natural pace of development. Pressure to grow up faster or exposing children to content or influences beyond their developmental ken does not make them smarter or savvier sooner. Instead, it fast-forwards them past critical steps in the developmental process.

Developmentally, this is the time children need parents and teachers to help them learn to tame impulsivity—learning to wait their turn, not cut in line, not call out in a class discussion—and for developing the capacity to feel happy and alone, connected to oneself and empathetic toward others.

With nature pressing for human interaction and a child’s world of possibility expanding in the new school environment, to trade it all for screen time is a terrible waste of a child’s early school years.

Some things in life you just have to do in order to learn, and do a lot of to grow adept at it. Like learning to ride a bike, developing these inner qualities of character and contemplation calls for real-life practice. In the absence of that immersion-style learning, time on screens can undermine a child’s development of these important social skills and the capacity to feel empathy

Emotional and social development, like cognitive development, can benefit from “judicious use” of tech

“But if it is used in a nonjudicious fashion, it will shape the brain in what I think will actually be a negative way,”

“the problem is that judicious thinking is among the frontal-lobe skills that are still developing way past the teenage years. In the meantime, the pull of technology is capturing kids at an ever earlier age, when they are not generally able to step back and decide what’s appropriate or necessary, or how much is too much.”

in school, they take their cues from the crowd-sourced conversations they hear among friends and on social media. For girls, even seven-year-olds on the school playground, sexy is the new cute. Thin is still in, but for ever younger girls. In a study of the effects of media images on gender perceptions, one study reported that by age three, children view fatness negatively, and free online computer games for girls trend toward fashion, beauty, and dress-up games, reinforcing messages that your body is your most important asset.

prior to Britney Spears, most girls had ten years of running around, riding their bikes, and experiencing their bodies as a source of energy, movement, confidence, and skills. That was before children’s fashions included thong panties for kindergarten girls, stylish bras for girls not much older, lipstick or lip gloss as a top accessory for nearly half of six-to nine-year- old girls, and “Future Pimp” T-shirts for schoolboys.

Boys, too, are under pressure. They must measure up to the super-masculine ideal of the day, portrayed and defined by more graphic, sadistic, and sexual violence than the superheroes of yesterday. Homophobia and the slurs used to express it remain a common part of boy culture, but now at an earlier age, as does a derogatory view of all things female and an increasingly sexualized attitude toward girls.

Children do best when they are free and flexible to try on and cross over the gender codes—girls who skateboard and play ice hockey, boys who draw or dance, boys and girls who enjoy each other without “dating” overtones.

TV viewing helped white boys feel better about themselves, and left white girls, black girls, and black boys feeling worse. White boys saw male media comparisons as having it good: “positions of power, prestigious jobs, high education, glamorous houses, a beautiful wife” all easily attained, as if prepackaged. Girls and women saw female media comparisons in more simplistic and limited roles, “focused on the success they have because of how they look, not what they do, what they think or how they got there.” Black boys also saw their media comparisons in the negative, limited roles of “criminals, hoodlums and buffoons, with no other future options.”

there is “a clear link between media violence exposure and aggression” as well as to other damaging consequences including eating disorders, poor body image, and unhealthy practices in an effort to achieve idealized appearances. “Failure to live up to the specific media stereotypes for one’s sex is a blow to a person’s sense of social desirability,”

Historically, scientists have believed that early settlers known as the Clovis people migrated south through an ice-free corridor that formed as the glaciers melted at the end of the Ice Age, roughly 11,500 years ago. That “Clovis first” theory, though dominant for most of the 20th century, is a tricky one: recent radiocarbon analysis of human remains discovered at an ancient site in Chile found they were about 14,000 years old. Either the analysis was wrong, or the theory was.

A second and increasingly popular possibility is that the people of Beringia, as the land bridge is known, built themselves some boats, traveled south and began settling the American coastline long before the inland ice had melted. The Science Advances study backs up that theory: It found that the genetic diversity of early Americans exploded about 16,000 years ago, suggesting that they’d made it to the warm, wide open spaces of the North and South American continents and flourished.

By 14,000 years before present, humans inhabited the Americas from Alaska to Chile.

mitochondrial DNA only offers clues about matrilineal lines of kinship — men, and women who didn’t have children, are left out of the equation.

Among these were a horse skull and hiking staffs from the Viking Age. An arrow shaft found by the archaeologists is from the Stone Age.

“We often find things associated with hunting. There are also ordinary objects such as mittens and shoes and the skeletons of horses that died on the trek across the mountains. This makes it a real thrill,” says Pilø.

Yes, billions of dinosaur bodies died and fell to the Earth here in this span, and trillions more dinosaur footsteps pressed into the Earth, but hardly a trace remains today. A cryptic smattering of lakeside footprints represents their entire contribution to the Triassic period. A few bones and footsteps miraculously preserved in New England and Nova Scotia are all that remains from the entire 27-million-year Early Jurassic epoch. No trace of dinosaurs remains whatsoever from the 18-million-year Late Jurassic. A handful of bones from one layer in Maryland represents the entire 45-million-year Early Cretaceous; the Late Cretaceous gives up a Hadrosaurus in New Jersey, and part of a tyrannosaur in Alabama, but mostly comprises unimpressive fragments of bone and teeth that cover the remaining 34 million years of the Earth’s most storied age, until doomsday

So that’s what 180 million years of complete dominance buys you in the fossil record. What, then, will a few decades of industrial civilization get us? This is the central question of the Anthropocene—an epoch that supposedly started, not tens of millions of years ago, but perhaps during the Truman administration

as the example of the dinosaurs shows, the chance that any city-swallowing delta deposit from a window of time only a few centuries wide would be lucky enough to be not only buried and preserved for safekeeping, but then subsequently not destroyed—in the ravenous maw of a subduction zone, or sinking too close to the cleansing metamorphic forge of Earth’s mantle, or mutilated in some m

there exists a better word in geology than epoch to describe our moment in the sun thus far: event. Indeed, there have been many similarly disruptive, rapid, and unusual episodes scattered throughout Earth history—wild climate fluctuations, dramatic sea-level rises and falls, global ocean-chemistry disasters, and biodiversity catastrophes

nd then, after all that, find itself, at a given point in the far future, fantastically lucky enough to have been serendipitously pushed up just enough so as to be exposed at the surface, but not too high as to have been quickly destroyed by erosion … is virtually ni

What else of us could be sampled from this sliver of deep-sea-muck-turned-rock—these Anthropocene clays and shale layers? Pass it through a mass spectrometer and you would see, encoded in its elements, the story of the entire planet in this strange interval, the Great Derangement of the Earth’s systems by civilization. You would see our lightning-fast injection of hundreds of gigatons of light carbon into the atmosphere written in the strange skew of carbon isotopes in this rock—as you do in rocks from the many previous carbon-cycle disasters of Earth history. The massive global-warming pulse created by this carbon disaster would be written in oxygen isotope

The sulfur, nitrogen, thallium, and uranium isotopes in these rocks (to mention just a few) would whisper to you—again, in squiggles on a graph—that the global ocean lost much of its oxygen during this brief but enigmatic interval. Strontium isotopes would tell you that rock weathering dramatically accelerated worldwide for a few tens of thousands of years as sweltering, violent storms attacked the rocks and wore down the continents during a brief, CO2-driven fever.

The most enduring geological legacy, instead, will be the extinctions we cause. The first wave of human-driven extinctions, and the largest hit to terrestrial megafauna since the extinction of the dinosaurs, began tens of thousands of years ago, as people began to spread out into new continents and islands, wiping out everything we tend to think of as “Ice Age” faun

we’re very likely to return to our regularly scheduled programming and dive back into a punishing Ice Age in the next half-million years. This means that sea level—after shooting up in the coming millennia by our own hand, and potentially burying coastal settlements in sediment (good for fossilization)—will eventually fall hundreds of feet below where it is today, and subject the shallow continental shelves, along with our once submerged cities and magnificent seams of garbage, to the cold winds of erosion (bad for fossilization), where they’ll be mostly reduced to nothing

The first major mass extinction, 445 million years ago, took place in multiple pulses across a million years. An event. The second major mass extinction, 70 million years later, took place over 600,000 years—400,000 years longer than the evolutionary history of Homo sapiens.

The idea of the Anthropocene inflates our own importance by promising eternal geological life to our creations. It is of a thread with our species’ peculiar, self-styled exceptionalism—from the animal kingdom, from nature, from the systems that govern it, and from time itself. This illusion may, in the long run, get us all killed.

The gas seemingly played a major role in amplifying the effects of the ice ages, which were caused by wobbles in the earth’s orbit. The geologic record suggests that as the earth began cooling, the amount of carbon dioxide fell, probably because much of it got locked up in the ocean, and that fall amplified the initial cooling. Conversely, when the orbital wobble caused the earth to begin warming, a great deal of carbon dioxide escaped from the ocean, amplifying the warming.

Their best estimate is that if the amount of carbon dioxide doubles, the temperature of the earth will rise about five or six degrees Fahrenheit. While that may sound small given the daily and seasonal variations in the weather, the number represents an annual global average, and therefore an immense addition of heat to the planet.

Moreover, scientists say that an increase of five or six degrees is a mildly optimistic outlook. They cannot rule out an increase as high as 18 degrees Fahrenheit, which would transform the planet.

Among the most prominent of these contrarians is Richard Lindzen of the Massachusetts Institute of Technology, who contends that as the earth initially warms, cloud patterns will shift in a way that should help to limit the heat buildup. Most climate scientists contend that little evidence supports this view,

China’s citizens, on average, still use less than a third of the energy per person as Americans. But with 1.3 billion people, four times as many as the United States, China is so large and is growing so quickly that it has surpassed the United States to become the world’s largest overall user of energy.

“When I go see things with my children, I let them know they might not be around when they’re older,” he said. “ ‘Go enjoy these beautiful forests before they disappear. Go enjoy the glaciers in these parks because they won’t be around.’ It’s basically taking note of what we have, and appreciating it, and saying goodbye to it.”

“annual average temperatures have increased by 1.8°F across the contiguous United States since the beginning of the 20th century” and that “annual median sea level along the U.S. coast . . . has increased by about 9 inches since the early 20th century as oceans have warmed and land ice has melted.”

he National Climate Assessment warns that global warming could cause a 10 percent decline in gross domestic product and that the “potential for losses in some sectors could reach hundreds of billions of dollars per year by the end of this century.” Iowa and other farm states will be particularly hard hit as crops wilt and livestock die.

Compared with the crushing costs of climate change, the action needed to curb greenhouse-gas emissions is modest and manageabl

a carbon tax would increase average electricity rates from 17 cents to 18 cents per kilowatt-hour. The average household, he writes, would see spending on energy rise “only about $35 per month.” That’s not nothing — but it’s better than allowing climate change to continue unabated

I’ve owned up to the danger. Why haven’t other conservatives? They are captives, first and foremost, of the fossil fuel industry, which outspent green groups 10 to 1 in lobbying on climate change from 2000 to 2016. But they are also captives of their own rigid ideology

There’s little predictability in how things will play out after this anthropogenic jolt, especially in the living world. [More on the “great acceleration” behind the jolt is here.]

That’s a very different sensation than, say, mourning the end of nature. It’s more a celebration, in a way — a deeper acceptance of our place on the planet, with all of our synthetic trappings, and our faults, as fundamentally natural.

on whether it’s possible to have a “good Anthropocene.” Kolbert’s Twitter post last spring nicely captured their view:

Taking full ownership of the Anthropocene won’t be easy. The necessary feeling is a queasy mix of excitement and unease. I’ve compared it to waking up in the first car on the first run of a new roller coaster that hasn’t been examined fully by engineers.

Once you begin to get the many feedbacks bouncing off each other and bouncing off the Earth system, it’s going to be very hard to follow what’s going to happen, particularly biologically…. One could not imagine, at the very end of the Cretaceous, the beginning of the Tertiary, that the mammals — these itty-bitty little squeaky furry things, would take over – effectively taking the position that the dinosaurs held for so long. All we can say is that, for sure, it will be different. We’re going down a different trouser leg of history.

in the broadest sense we have to embrace the characteristics, good and bad, that make humans such a rare thing — a species that has become a planet-scale force.

“The way I would like to see it is in, say, 100 years in the future the London Geological Society will look back and consider this period…a transition from the lesser Anthropocene to the greater Anthropocene.”

Fully integrating this awareness into our personal choices and societal norms and policies will take time. It is “the great work,” as Thomas Berry put it.

Technology alone will not do the trick. Another keystone to better meshing humanity’s infinite aspirations with life on a finite planet will be slowly shifting value systems from the foundation up

Edward O. Wilson’s “Biophilia” was a powerful look outward at the characteristics of the natural world that we inherently cherish.

Now we need a dose of what I’ve taken to calling anthropophilia, as well.

We have to accept ourselves, flaws and all, in order to move beyond what has been something of an unconscious, species-scale pubescent growth spurt, enabled by fossil fuels in place of testosterone.

We’re stuck with “The World With Us.” It’s time to grasp that uncomfortable, but ultimately hopeful, idea.

“It was a pretty drastic change; it happened overnight,” McCormick says. “The ancient witnesses really were onto something. They were not being hysterical or imagining the end of the world.”

The effects of the 536 eruption were compounded by eruptions in 540 and 547, and it took a long time for the Northern Hemisphere to recover. “The Late Antique Little Ice Age that began in the spring of 536 lasted in western Europe until about 660, and it lasted until about 680 in Central Asia,” McCormick says.

This period of cold and starvation caused economic stagnation in Europe that intensified in 541 when the first bubonic plague broke out. The plague killed between one-third and one-half of the population in the Byzantine Empire, or Eastern Roman Empire.

Before some basic tools were found here in 2010, it had been believed that humans had entered Britain much later, about 700,000 years ago, Dr. Ashton said. (Before 2005, when another set of tools was discovered in Suffolk, the presumed date was 500,000 years ago.)

“We can reconstruct the climate and climate change nearly one million years ago,” Dr. Ashton said. “The big lesson is, we have to adapt. Whether we like it or not, the climate will change — it always has — and today we are accelerating that change.”

Standing on the ridge above Cardigan Bay in Borth, Dr. Bates described what the area would have looked like at the height of the last ice age some 20,000 years ago: more than half a mile of ice overhead and dry land stretching across today’s North Sea. The sea level was 400 feet lower than it is today.“You could have walked from Denmark to Yorkshire in those days,”

About 10,000 years ago, temperatures warmed sharply, by eight to 10 degrees Fahrenheit. By that time, the European ice sheets had melted, but the much thicker North American sheets took much longer. While the climate had warmed to today’s levels, allowing mixed oak woodland to grow and humans to recolonize Britain, the sea level remained some 130 feet lower for another 3,000 years.

When it did rise, it would have been traumatic for the population, wiping out whatever settlement there was,

“Even in the reduced life span of the day, the coastline would have advanced dramatically,”

The ultimate legend, of course, is Atlantis, which Plato placed somewhere in the North Atlantic.

“It was a traumatic geological event, and people turned it into a story to make sense of it,”

“One is talking about artefacts that were put in the deep freeze 1,000 years ago, and later and earlier, and were taken out when we found them. So a textile is almost perfectly preserved, one might find arrows with the fletching perfectly preserved, with the sinew still in place, the glue that glued the feathers to the shaft. These are quite remarkable finds.”

While the objects are frequently “extraordinary”, he said, “what is really important archaeologically about them isn’t the individual objects, it’s the story that putting together all of the objects can tell you” about the pass and the people who travelled it.

Our foundation of Earth knowledge, largely derived from historically observed patterns, has been central to society’s progress. Early cultures kept track of nature’s ebb and flow, passing improved knowledge about hunting and agriculture to each new generation. Science has accelerated this learning process through advanced observation methods and pattern discovery techniques. These allow us to anticipate the future with a consistency unimaginable to our ancestors.

But as Earth warms, our historical understanding will turn obsolete faster than we can replace it with new knowledge. Some patterns will change significantly; others will be largely unaffected

The list of possible disruptions is long and alarming.

Historians of the next century will grasp the importance of this decline in our ability to predict the future. They may mark the coming decades of this century as the period during which humanity, despite rapid technological and scientific advances, achieved “peak knowledge” about the planet it occupies

One exception to this pattern-based knowledge is the weather, whose underlying physics governs how the atmosphere moves and adjusts. Because we understand the physics, we can replicate the atmosphere with computer models.

But farmers need to think a season or more ahead. So do infrastructure planners as they design new energy and water systems

The intermediate time period is our big challenge. Without substantial scientific breakthroughs, we will remain reliant on pattern-based methods for time periods between a month and a decade. The problem is, as the planet warms, these patterns will become increasingly difficult to discern.

The oceans, which play a major role in global weather patterns, will also see substantial changes as global temperatures rise. Ocean currents and circulation patterns evolve on time scales of decades and longer, and fisheries change in response. We lack reliable, physics-based models to tell us how this occurs.

Our grandchildren could grow up knowing less about the planet than we do today. This is not a legacy we want to leave them. Yet we are on the verge of ensuring this happens.

After that, you see for the first time people related to later European hunter-gatherers who have contributed a little bit to present-day Europeans. That happens beginning 35,000 to 37,000 years ago. Then the ice sheets descend across northern Europe and a lot of these populations are chased into these refuges in the southern peninsulas of Europe. After the Ice Age, there’s a repeopling of northern Europe from the southwest, probably from Spain, and then also from the southeast, probably from Greece and maybe even from Anatolia, Turkey

Again, after 9,000 years ago, there’s a mass movement of farmers into the region which almost completely replaces the hunter-gatherers with a small amount of mixture

And then again, after 5,000 years ago, there’s this mass movement at the beginning of the Bronze Age of people from the steppe, who also probably bring these languages that are spoken by the great majority of Europeans today.

Reich: Archaeology has always been political, especially in Europe. Archaeologists are very aware of the misuse of archaeology in the past, in the 20th century. There’s a very famous German archaeologist named Gustaf Kossinna, who was the first or one of the first to come up with the idea of “material culture.” Say, you see similar pots, and therefore you’re in a region where there was shared community and aspects of culture.

He went so far as to argue that when you see the spread of these pots, you’re actually seeing a spread of people and there’s a one-to-one mapping for those things. His ideas were used by the Nazis later, in propaganda, to argue that a particular group in Europe, the Aryans, expanded in all directions across Europe.

This was used to justify their expansionism in the propaganda that the Germans used in the run-up to the Second World War.

So after the Second World War, there was a very strong reaction in the European archaeological community—not just the Germans, but the broad continental European archaeological community—to the fact that their discipline had been used for these terrible political ends. And there was a retreat from the ideas of Kossinna.

one of the things the ancient DNA is showing is actually the Corded Ware culture does correspond coherently to a group of people. [Editor’s note: The Corded Ware made pottery with cord-like ornamentation and according to ancient DNA studies, they descended from steppe ancestry.] I think that was a very sensitive issue to some of our coauthors

Our results are actually almost diametrically opposite from what Kossina thought because these Corded Ware people come from the East, a place that Kossina would have despised as a source for them.

it is true that there’s big population movements, and so I think what the DNA is doing is it’s forcing the hand of this discussion in archaeology, showing that in fact, major movements of people do occur. They are sometimes sharp and dramatic, and they involve large-scale population replacements over a relatively short period of time. We now can see that for the first time.

Zhang: As you say, the genetics data is now often ahead of the archaeology, and you keep finding these big, dramatic population replacements throughout human history that can’t yet be fully explained. How should we be thinking about these population replacements? Is there a danger in people interpreting or misinterpreting them as the result of one group’s superiority over another?

When you see these replacements of Neanderthals by modern humans or Europeans and Africans substantially replacing Native Americans in the last 500 years or the people who built Stonehenge, who were obviously extraordinarily sophisticated, being replaced from these people from the continent, it doesn’t say something about the innate potential of these people. But it rather says something about the different immune systems or cultural mismatch.

Zhang: On the point of immune systems, one of the hypotheses for why people from the steppe were so successful in spreading through Europe is that they brought the bubonic plague with them. Since the plague is endemic to Central Asia, they may have built up immunity but the European farmers they encountered had not.

ut there have been profound and Earth-shattering events, again and again, every few thousand years in our history and that’s what ancient DNA is telling us.

if you actually take any serious look at this data, it just confounds every stereotype. It’s revealing that the differences among populations we see today are actually only a few thousand years old at most and that everybody is mixed.

I think that if you pay any attention to this world, and have any degree of seriousness, then you can’t come out feeling affirmed in the racist view of the world. You have to be more open to immigration. You have to be more open to the mixing of different peoples. That’s your own history.

“The climate crisis is already here,” Iceland’s Prime Minister, Katrín Jakobsdóttir, told the crowd. “It is not just this glacier that has disappeared. We see the heat waves in Europe. We see floods. We see droughts.” Film crews pointed their cameras, while the wind whipped Jakobsdóttir’s hair and the paper on which she had written her remarks. “The time has come not for words, not necessarily for declarations, but for action,” she said.

“Some of the students who are here today are twenty years old,” he said, his voice shaking. “You may live to be a healthy ninety-year-old, and at that time you might have a favorite young person—a great-grandchild, maybe—who is the age you are now. When that person is a healthy ninety-year-old, the year will be 2160, and this event today will be in the order of direct memory from you to your grandchild

Sigurðsson, the glaciologist, insisted to Howe and Boyer that, even though Okjökull was the smallest named glacier in Iceland, its death was a major loss.

“A good friend has left us,” Sigurðsson said.

“Ok is the first Icelandic glacier to lose its status as a glacier. In the next 200 years, all our glaciers are expected to follow the same path.

When Sigurðsson conducted a glacier inventory in the early two-thousands, he found more than three hundred glaciers in Iceland; a repeat inventory, in 2017, revealed that fifty-six had disappeared. Many of them were small glaciers in the highlands, which had spent their lives almost entirely unseen. “Most of them didn’t even have names,” he told me. “But we have been working with local people to name every glacier so that they will not go unbaptized.”

in the past several years alone, we have witnessed not only an acceleration of the great thaw but also the sudden bleaching of the coral reefs, the rapid spread of the Sahara desert, continuous sea-level rise, the warming of the oceans, and record-breaking hurricanes each season and every year. This is one of the most distressing things about being alive today: we are witnessing geologic time collapse on a human scale.

Then the mountainside levelled, and the sight of the crater purged all thoughts from my head. The ice was gray, lifeless, uncanny.

“The age of this glacier was about three hundred years,” he said. “Its death was caused by excessive summer heat. Nothing was done to save it.”

Before more colonists arrived from England, the population of Jamestown dwindled. The Virginia Company had predicted that disease would manifest, and lives would be lost. Concerned about prying eyes and an ambush on a weakened colony, they had stressed "above all things" that the colonists hide the sick and bury the dead in unmarked graves. The men followed orders, burying their deceased out of sight behind the fort wall. When the death toll spiked between May and September of 1607, they also made use of double burials with two men laid to rest in the same shaft.

Surrounded by Powhatan’s warriors and trapped inside the fort, the settlers eventually ran out of food and were forced to eat whatever they could find: horses, dogs, rats, snakes, leather shoes and, according to forensic evidence, even each other.

The Virginia Company offered attractive incentives for would-be wives: free transportation, a plot of land, a dowry of clothing and furnishings. They also allowed the women to choose their husbands after entertaining the eager suitors. The tactic had some success, and, the women, in theory, became America’s first mail-order brides.

King James I had a strong, and well-known, distaste for tobacco. “A custome lothsome to the eye, hatefull to the Nose,” he once declared. It’s ironic that this very crop gave Jamestown its economic viability. The settlement had struggled to find a marketable commodity that it could trade and ship back to England for profit. The colonists dabbled in forestry, silk making and glassmaking, with little financial return.

. Thereafter, each new English colony sought its own legislature. Although there were challenges and power struggles, the concept of elections, creation of laws and power through and by the people, began in America's first English settlement.

Before their arrival, European explorers assumed America's climate would match that of other lands situated at the same latitude. They soon discovered that the New World was both hotter and colder than they expected. To make matters worse, the already harsh and unpredictable environment was exacerbated by climate change, namely a “Little Ice Age” that lasted from 1550 to 1800.

No one knows where or how Rolfe obtained the seeds. Until then, Spain had controlled tobacco on the European markets and selling seeds to non-Spaniards was a crime punishable by death. Rolfe may have smuggled the seeds from Bermuda, where some of the fleet was shipwrecked for 10 months before arriving in Jamestown, or somewhere in the Caribbean. Either way, the risk paid off.

Historians believe that Rolfe either falsified his report to conceal what the English had done or that the White Lion swapped flags with a Dutch ship while out at sea, causing Rolfe to incorrectly record the ship’s country of origin.

Active archaeological excavation, research and analysis have been ongoing since 1994 at the original site of Jamestown. Archaeologists have found parts of the palisade of the original 1607 fort, discovered the site of the second church and unearthed the remains of a handful of the settlement’s early inhabitants.

First and foremost, the climate was changing. Sound familiar? Medieval Europe benefitted from several centuries of warmer weather, which boosted crop yields, but by the 14th century, the world was entering the so-called Little Ice Age

As the population grew, increasingly marginal land was turned over to agriculture, with diminishing returns, resulting in lower yields per capita and pushing the population dangerously close to subsistence levels. This left little slack in the economy to absorb a significant shock, and the 14th century would soon bring one shock after another.

From AD 1000, Europe's population doubled or even tripled, and the economy became increasingly commercialized, underwritten by an increasingly sophisticated financial system, as new cities and towns emerged, universities were founded across the continent, and the magnificent Gothic cathedrals surpassed the Great Pyramid at Giza as the tallest man-made structures in the world.

Cooler and wetter weather depressed agricultural yields, at a time when there was already very little slack in the food supply. This contributed to a broader economic slowdown, as yields declined and prices rose, but it also brought Europe to the edge of famine.

beginning in 1311, Europe began to experience a series of crop failures across the continent in what became known as the Great Famine. Reaching a peak in northern Europe in 1315-1317, the Great Famine may have killed 5 to 10% of Europe's population

At the same time, Europe entered a prolonged period of heightened geopolitical conflict, during which a dizzying array of kingdoms, principalities, sultanates and city-states waged innumerable wars, both large and small.

These conflicts inhibited trade between northern and southern Europe and between western Europe and the eastern Mediterranean, further slowing the European economy and incurring a massive fiscal burden that would soon ruin the European financial system and provoke uprisings in both France and England

Northern Italy was the heart of the financial system at this time, and a small number of very large Italian banks, often referred to as "super-companies," were lending huge sums of money across Europe

All available money was loaned out or tied up in investments, leaving the banks severely under-capitalized and vulnerable to insolvency in the event of a sudden large withdraw or a major default on their loans.

war broke out between England and France in 1294, prompting King Edward I to withdraw huge sums of money from the Riccardi of Lucca, approximately equivalent to several billion dollars today. The Riccardi simply did not have the money, and Edward seized whatever assets he could. Then, over the following decades, three more super banks, the Frescobaldi, the Bardi and the Peruzzi, all of Florence, were each ruined by successive English kings who refused to pay their debts.

Meanwhile, the Catholic Church, the cultural and epistemological bedrock of Medieval Europe, was facing the most significant legitimacy crisis in centuries

he King's men attempted to arrest the elderly Pope, inadvertently killing him. Shortly thereafter, in 1305, a Frenchman, Clement V, was chosen to be the next pope, and the papacy was relocated to Avignon, France. This understandably cast a long shadow over the Holy See, and the Avignon Popes were widely disliked and distrusted. The crisis only deepened in 1378 when a second pope was elected in Rome and a third pope was briefly elected in 1409 before all three were deposed in 1417.

We might compare this crisis of faith with the current legitimacy crisis of science in the United States. Like the scientific method, the Church was a shared way of knowing — a pathway to common understanding, which was essential to the social order of Medieval Europe.

It was in the midst of this spiritual, economic and geopolitical crisis that the Black Death arrived, sweeping through Europe in 1347-1353 and upending the balance of power, almost overnight

the economic effects of the plague were nothing short of earthshattering. By killing perhaps 50% of the labor force, the Black Death drastically altered the supply of labor, land and coin. Wages skyrocketed, as labor was in short supply, and rents declined, as the plummeting population density created a surplus of land

Both of these developments substantially benefitted commoners, at the expense of the elite, particularly in England.

The archetypal serf was not paid for their work in the lord's fields — that was their obligation to the lord in exchange for the use of the lord's land. The modern equivalent would be if your landlord was also your boss, and in order to live in your apartment, you had to sign away your freedom and that of your children, in perpetuity.

Not only that, the medieval lord was also the primary unit of legal, civic and military power, often serving as the first stop for legal matters and the first defense against brigands and rival kingdoms.

With perhaps half the population gone, there were simply not enough peasants to work the land, and the average income of the English lord declined significantly. In response, the lord's wheat fields were increasingly turned over to livestock, or rented out to tenant farmers, who would pay the lord a fixed rent, keeping the agricultural produce for themselves.

The ambitious commoner could now acquire sizable tracts of land, and with the agricultural product of that land entirely at their disposal, commoners were incentivized to maximize the productivity of their land and sell the surplus at market for a profit. This transition is often referred to as the birth of Agrarian Capitalism.

In the wake of the Black Death, plague doctors were among the first to believe they had surpassed the knowledge of the Greek and Roman world; ironically, they were wrong, but the lower mortality of later outbreaks led many doctors to proclaim they had cured the disease, which instilled a new faith in scientific progress

Sumptuary laws, which restricted what commoners could wear and eat, also became common during the 14th and 15th Centuries. However, these laws do not appear to have been effective, and tensions continued to mount between the aristocracy and the wider populace, who were increasingly impatient for change.

Urban laborers and craftsmen also benefitted from rising wages. The average lifespan increased, and standards of living improved across the board. The shortage of skilled tradesmen even created new opportunities for urban women

starting in the 14th century, infantry units comprised of commoners, like the Swiss pikemen and English longbowmen, began to win a series of decisive victories against mounted knights, revolutionizing military tactics and hastening the obsolescence of the feudal aristocracy.

a new intellectual spirit was taking root across western Europe. Influential thinkers like John Wycliffe and Marsilius of Padua began to question the worldly authority of both the Church and the state, arguing that power rested ultimately with the populace rather than the ruler, and the unworthy ruler could lose their right to govern

This, combined with the soaring fiscal burden of near-constant war, set off a series of uprisings, most notably the French Jacquerie of 1358 and the English Peasants' Revolt of 1381. The aristocracy responded with force wherever they could, but they could not turn back the clock.

seven-hundred years later, what, if anything, can we learn from this — what can the crises and consequences of the 14th century tell us about our own pandemic and the impending aftermath?

There will be no labor shortage in the wake of the coronavirus; quite the opposite, there will likely be a labor surplus, due to the ensuing economic contraction. As for rents, the housing market is essentially frozen as people shelter in place, and housing prices are likely to decline in a recession, but the real cost of housing relative to income is unlikely to see the kind of seismic shift experienced after the Black Death.

most presciently for our own time, Europe was headed for a climate catastrophe, and regardless of the Black Death, the continent would have almost certainly faced a series of demographic shocks, like the Great Plague, until considerable changes were made to the existing socio-economic system.

The lesson we should take from this today is not the differences between the coronavirus and the Black Death, but rather the broader similarities between the 14th century and the 21st century

war between China and the US still looms ever larger, socio-economic inequality is reaching record levels, trust in institutions and our established epistemology is waning, and as we enter the worst depression since the 1930s, climate change once again threatens to throw us back into the Middle Ages

if we continue business as usual, what happens next is likely to be much worse. The calamitous 21st century is just getting started, and a more apt parallel for the Black Death is probably yet to come

Maria Lahtinen of the Finnish Museum of Natural History thinks she might have the answer as to how wolves and people squared the competitive circle while both species were still hunters.

archaeological evidence suggests that wolves were domesticated in woodlands fringing the ice sheets of the last ice age,

Dr Lahtinen calculates that, given the large size of prey animals in this environment, and humans’ need to eat a balanced diet with plenty of plant matter in it as well as flesh, there would have been a lot of surplus meat around from kills.

In the prefecture of Hokkaido, the traditional territory of the Ainu, government administrators now answer the phone, “Irankarapte,” an Ainu greeting. The government is planning a new Ainu museum, meant to open in time for the 2020 Olympic Games in Tokyo. In a country known for its almost suffocating homogeneity—to outsiders anyway, and not always fairly—embracing the Ainu is an extraordinary lurch into diversity.

Humans first landed on Hokkaido at least 20,000 years ago, probably arriving from Siberia via a land bridge in search of a less frigid environment. By the end of the last ice age, their descendants had developed a culture of hunting, foraging, and fishing.

The northerners’ ancient culture persisted largely unchanged until the seventh century

it appears that ancient islanders, bereft of any ursine population, must have imported their bears from the Hokkaido mainland. Did they struggle to bring live bears to the island, via canoe?

I was born in Hokkaido, 60 kilometers east of Sapporo,” he says. Yet he never learned the history of Hokkaido. Schools across the nation used a common history textbook, and when Kato was young, he only learned the story of Japan’s main island, Honshu.

On the surface, there is nothing about Hokkaido that is not Japanese. But dig down—metaphorically and physically, as Kato is doing—and you’ll find layers of another class, culture, religion, and ethnicity.
