The scientific events that shaped the decade

Navigating a more sustainable path will require ambitious political and industrial will, as much as scientific ingenuity.

In many countries — especially those afflicted by varying degrees of authoritarianism and climate-change denial — that will is in short supply. But researchers must not lose hope. Working with civil society, they must step up, get out of their comfort zones and recognize activism as part of their mission13. And they must fight to restore the status of facts and truth.

The 2010s were both remarkable but also troubling. With new knowledge, and a renewed dedication to social and environmental responsibility, the 2020s must be transformational.

Reading Seawater | Articles | Inference: International Review of Science

Oceanographers classify these elements into three groups: conservative, scavenged, and recycled.17 Conservative elements, which include the major constituents of seawater, such as sodium and chlorine, have residence times on the order of millions to hundreds of millions of years. Their residence times are much longer than mixing times, the period over which they are distributed via waves, currents, and eddies. If an element’s residence time is greater than its mixing time, its concentration will be fairly uniform throughout the ocean, and it can be considered to have reached a state of chemical equilibrium in seawater.

Recycled and scavenged elements have much shorter residence times, on the order of hundreds or thousands of years.18 As a result, there is insufficient time for these elements to achieve equilibrium through mixing, and their concentrations vary according to geography and depth. Scavenged elements include aluminum, lead, mercury, and other metals. These elements are attracted to the surfaces of fine clay particles and are exported from shallow waters as the particles sink to the ocean floor. The chemical concentration of scavenged elements decreases with depth in the water column.

The recycled elements exhibit the most interesting and complicated behavior of all the groups. These are the ingredients essential for life, such as carbon, copper, iodine, iron, nitrogen, phosphorous, and zinc. In the uppermost region of the ocean where almost all sea life can be found, these elements are limiting nutrients, whose scarcity makes them coveted commodities in the marine biosphere. Any of these elements lost by one organism will be snatched up by another, keeping their concentration in the water itself low. Over time, a fraction of these nutrients leaks into deeper and relatively uninhabited waters, and so the concentration of recycled elements generally increases with depth.

Surface currents, such as the Gulf Stream, transfer warmth from the tropics to higher latitudes. As it flows northward, the water cools and is subject to evaporative loss, becoming saltier and increasing in density as a result. To the north of Iceland, the Gulf Stream waters are denser than in the ambient North Atlantic and sink to the seafloor, returning south as a mirror-image deep ocean current. Prior to the formation of the Isthmus of Panama, the Gulf Stream was able to flow further north into the Atlantic, carrying heat to the high arctic. Once the saltiness of the Atlantic was no longer being diluted by the Pacific, the more saline water started sinking further south. In the absence of the heat these waters brought to the far north, winter snows persisted through thousands of summers and ice sheets grew.20

In the preoxidation era, iron emitted by submarine volcanoes could remain dissolved in the open ocean, commingling with sodium, calcium, and other ions. But when oxygen, produced by the ancestors of modern planktonic photosynthesizers, began to accumulate in shallow waters, it bonded with the iron atoms, pulling them to the seafloor. The oceans were eventually purged of iron.

The tremendous volume of iron formations, the source of all the steel ever forged, attests to the great abundance of iron in the Proterozoic oceans.

If not tears or sweat, seawater could perhaps instead be considered earth’s blood, its composition a proxy for the health of the planet.

A Walk to Kobe
Haruki Murakami

Maybe it’s exactly because of that that I wanted to take a walk there, alert and attentive to what I might discover. Perhaps I wanted to see for myself how this home town I’d lost all obvious connections with would appear to me now. How much of a shadow (or a shadow of a shadow) of myself I would discover there?

There’s hardly a cloud in the sky. An almost perfect May tableau. Still, as I sit there on the concrete bank and gaze at where the real sea used to be, everything here, like a tyre leaking air, slowly, and quietly, loses its sense of reality.

Japan’s Vegetable-Eating Men

Japanese men were spending about an hour a week on childcare and household duties, while women were spending 30 to 40 hours a week, numbers that had not shifted as the country had become more dependent on women’s labor outside the home. Japanese men were spending about an hour a week on childcare and household duties, while women were spending 30 to 40 hours a week, numbers that had not shifted as the country had become more dependent on women’s labor outside the home.

Not only are such men a large part of what has enabled Japan to dramatically increase the workforce participation of women in recent years (after lagging behind most developed countries since 2000, Japan shot past the US last year, with 76 percent of women now part of the labor force), but domestic bliss is increasingly becoming a viable alternative for those men who find themselves unable to secure a high-paying full-time job.

Just as the culture was expecting women to simply add work on top of full-time childcare and housework duties, men were being asked to just add involved parenting to an already-long—60 hours, in some cases—workweek.

Enter the IkuBoss. In 2015, the government launched a program targeted at shifting the workaholic mind-set of employers and bosses. Emerging alongside Prime Minister Shinzō Abe’s “work-style reform” proposal—which aims to decouple employees’ salaries from the number of hours they work, put a cap on overtime hours at 720 hours a year, and require companies to pay “regular” and “irregular” employees the same rate for the same work—IkuBoss intends to change the culture of work from the top down.

A Sociology of the Smartphone

we count on them to fill the dead spaces, the still moments and silences that used to occupy so much of our lives.

Most obviously, the smartphone replaced conventional telephones, leading to the widespread disappearance from streetscapes everywhere of that icon of midcentury urbanity, the telephone booth, and all the etiquettes of negotiated waiting and deconfliction that attended it. Where phone booths remain, they now act mostly as a platform for other kinds of services—WiFi connectivity, or ads for sex workers.

As a result, it’s already difficult to contemplate objects like a phone booth, a Filofax or a Palm Pilot without experiencing a shock of either reminiscence or perplexity, depending on the degree of our past acquaintance.

a rechargeable lithium-ion or lithium-polymer battery capable of sustaining roughly 1,500 charging cycles. This will yield just about four years of use, given the need to charge the phone daily, though experience suggests that few of us will retain a given handset that long.

the performance of everyday life as mediated by the smartphone depends on a vast and elaborate infrastructure that is ordinarily invisible to us.

according to Google, four out of every five consumers use the map application to make local searches, half of those who do so wind up visiting a store within twenty-four hours, and one out of every five of these searches results in a conversion, or sale.

The only way to hide from that knowledge is to decouple ourselves from the fabric of connections that gives us everything else we are. And that is something we clearly find hard to do, for practical reasons as much as psychic ones: network connectivity now underwrites the achievement of virtually every other need on the Maslovian pyramid, to the extent that refugees recently arriving from warzones have been known to ask for a smartphone before anything else, food and shelter not excluded.

The Reckoning
She played dead as the sound of gunshots reverberated around her, echoing off the red tile roofs and limestone walls. Dozens of students had run home to retrieve their deer rifles, and the echo of return fire rang out as they came back to take aim at the gunman.
