November 18, 2022 - Why Scientists Got the Fast Pace of Arctic Warming Wrong

S15

Why Scientists Got the Fast Pace of Arctic Warming Wrong Climate scientists have a surprising habit: They often underplay the climate threat. In 2007 a team led by Stefan Rahmstorf compared actual observations with projections made by theoretical models for three key climate variables: atmospheric carbon dioxide, global average temperature and sea-level rise. While the projections got CO2 levels right, they were low for real temperature and sea-level rise. In 2008 Roger Pielke, Jr., found that sea-level rise was greater than forecast in two of three prior Intergovernmental Panel on Climate Change reports. In 2009 a review of hundreds of papers on climate change identified several areas where scientists had lowballed event predictions but none in which they had overestimated them. In 2013 researcher Keynyn Brysse, then at the University of California, San Diego, along with other colleagues and me, pointed out that these underestimates represent a kind of bias. Scientists tended toward lower projections because they did not want to be accused of making dramatic and exaggerated claims. The articles reporting the underestimates have been widely cited, so one might think that by now scientists would have taken corrective steps. Continued here

How Can the World Prepare for the Next Pandemic? The COVID pandemic is not over, but countries must start to prepare for the next one to avoid a similar or even worse outcome The COVID-19 pandemic is not over, and already its cost is staggering. The disease could have contributed to around 17 million deaths. And, by 2024, the hit to the global economy could reach US$12.5 trillion. Everyone has experienced an extraordinary few years that few people would want to repeat. If the world is to avoid a similar or worse event in the future, countries must ensure that they are better prepared to deal with pandemics. Continued here

James Webb Captures a Protostar in a Fiery Hourglass Looking at the James Webb Space Telescope’s latest showstopping image of a faraway protostar is like peering back to a time when the sun and planets of our solar system were just beginning to form. The dazzling new photo, which NASA shared Wednesday, shows the fiery hourglass shape made by a star in its infancy. Webb snapped the portrait using its near-infrared camera (NIRCam), which can capture scenes in the wavelength range of 0.6 to 5 microns—beyond what’s detectable in the visible spectrum.

NASA's Artemis is humanity's first step toward space colonization In the early morning hours of Wednesday, November 16, NASA successfully launched the first test of its Artemis I space launch system. Because the launch was postponed a number of times by technical problems or bad weather, there was fear that some misfortune hung over the mission. Along with the $4.1 billion price tag attached to this launch alone, the setbacks had commentators asking what exactly the point was of all this effort.  But while there are valid criticisms — for example about NASA not including reusable launch technologies — the naysayers miss a broader, vital point. The Artemis program is about a lot more than this one launch. It’s about the long-term future of humanity. Continued here

Political Leaders Must Act Now to Thwart the Next Pandemic To make sure that COVID is the last pandemic of such devastation, political leaders must change their mindset and take these actions In the past two decades, the time between deadly international disease outbreaks has shortened, and the human and economic cost of these outbreaks has grown. In 2002, severe acute respiratory syndrome (SARS) led to 800 deaths and US$40 billion in economic losses. The 2014 Ebola outbreak in West Africa caused more than 11,000 deaths and $53 billion in economic and social losses. In early 2020, COVID-19 spread rapidly worldwide, and is estimated to have contributed to more than 17 million deaths, with economic losses estimated to reach $12.5 trillion by 2024. Delays in alerting the world to these threats led to wider spread and more loss of life. Continued here

Why the Emoji Skin Tone You Choose Matters “I'm a white person, and despite there being a range of skin tones available for emoji these days, I still just choose the original Simpsons-esque yellow. Is this insensitive to people of color?” I don't think it's possible to determine what any group of people, categorically, might find insensitive—and I won't venture to speak, as a white person myself, on behalf of people of color. But your trepidation about which emoji skin tone to use has evidently weighed on many white people's minds since 2015, when the Unicode Consortium—the mysterious organization that sets standards for character encoding in software systems around the world—introduced the modifiers. A 2018 University of Edinburgh study of Twitter data confirmed that the palest skin tones are used least often, and most white people opt, as you do, for the original yellow. Continued here

How to handle an overload of grief When I was 27, my mother told me she was dying of ALS, a fatal neurodegenerative disease with no cure. She died the following summer, and not long after, my father was diagnosed with cancer. He successfully completed treatment, but when the cancer returned, he didn’t survive. From the moment my mother shared her diagnosis and leading up to my father’s funeral, it felt like my head was being held under water. I could only surface for enough air to survive, but not long enough to understand the enormity of what had occurred. Before I could come to terms with one loss, I was experiencing another.

As the world goes cashless, how are our spending habits changing? In 1949, a businessman named Frank McNamara was dining at a New York City restaurant when he realized he had forgotten his wallet at home. The bill came. His wife covered for him. Embarrassed and resolved never to let it happen again, McNamara helped start the Diners Club — the world’s first payment card that became widely accepted by mainstream merchants. The Diners Club was the first step on the journey to a world where an estimated 2.8 billion credit cards are currently in use, roughly one-third of which are in the U.S. Since 2016, global non-cash payments have increased by more than 60 percent. It’s estimated that a quarter of the world’s retail transactions will be conducted online by 2025, with very little physical money changing hands at all. We’re using contactless payments, mobile banking apps, and backstage direct debits for more and more things. Continued here

Digital twins: Flying high, flexing fast After discussing the fundamentals of digital twins and the opportunities they offer, we’re expanding our exploration by taking a look at how digital methods help transform product development. Join McKinsey partner Kimberly Borden and senior adviser Dr. Will Roper in a conversation about the value of digital technologies in production applications. Their discussion, which examines the use of digital approaches to design and development in Formula One racing and in aerospace and defense, shows how a software development style can have a big impact on the production of hardware. This episode, recorded at Farnborough International Airshow and introduced by Christian Johnson, the managing editor of McKinsey’s Operations Practice, explores the digital imperative in the design and development of products. It also considers the need for a pragmatic delivery approach to ensure that big ideas can be executed. The conversation has been edited for clarity. Continued here

Your Competitors Aren't Always Who You Think They Are When it comes to strategy, one way to meet radically new expectations in your industry is to draw from the impressive and surprising strategies that are being used in other industries. Why can’t interacting with an insurance company be as responsive and transparent as interacting with Uber? Why can’t checking into a hospital be as seamless as checking into a hotel? These are the sorts of questions that more and more customers are asking, and the questions that a winning business strategy must answer. You won’t find those answers if you limit your strategic vision to what other companies in your field are doing. Remember, your competitors aren’t always who you think they are. Continued here

What's the real reason you can't go faster than the speed of light? Albert Einstein is frequently regarded as one of the most influential scientists of all times, with brilliant insights about the laws of nature. However, his work has one very disappointing consequence, especially for science buffs who hope one day to travel to distant stars. His theory demonstrated that there is a fastest speed in the Universe: the speed of light. That means the shortest possible round-trip to the nearest star will take nearly a decade. But just how does that work? Even the most informed science enthusiasts often have a wrong, or at least incomplete, understanding of why you can’t go faster than light. Continued here

Should a murderer be allowed to publish scientific papers? Between 1996 and 2021, Valery Fabrikant has published nearly 60 scientific papers across more than a dozen journals, and he’s done it all from a prison cell. On August 24, 1992, the now former associate professor of mechanical engineering at Concordia University in Montreal, Quebec shot and killed four of his colleagues and wounded another. Prior to the massacre, Fabrikant’s dozen-year employment at the university had been antagonistic, to say the least. The irascible, albeit brilliant, scientist quarreled with peers and irked students. Angered at being repeatedly denied tenure, he blamed everyone around him. His anger eventually boiled over into mass murder. Continued here

Why Did Flu Season Start So Early This Year? Reduced population immunity resulting from COVID precautions, and a phenomenon called viral interference, may have influenced this flu season’s early start The U.S. influenza season has arrived much earlier than usual. The Centers for Disease Control and Prevention first detected the early increases of flu activity in mid-October. The agency noted that the phenomenon was happening in most of the country, but more intensely in the Southeast and in south-central regions. A month later, levels of the virus continue to rise steeply. According to the latest CDC flu report, 25 states or jurisdictions now experience high or very high levels of outpatient visits for influenza-like illness, which is characterized by fever plus cough or sore throat.

'It's important to bring the spirit of emergencies to the long term' Business leaders may feel that they have been dealing with a never-ending series of crises since the COVID-19 pandemic began nearly three years ago. A health emergency ushered in a supply chain disruption that yielded an inflation predicament; add in higher energy prices and other upheavals, and the demands on leaders’ crisis management skills are at an all-time high. For perspective on how to thrive during emergencies, we turned to José Andrés, a Spanish-born chef whose company encompasses nearly 40 restaurants globally. Most chefs can offer some wisdom in dealing with pressure, given the relentless atmosphere of restaurant kitchens. But Andrés’s expertise is unique: in 2010, he founded World Central Kitchen, a nonprofit whose mission is to deliver fresh meals to people in need during emergencies including tornados, hurricanes, pandemics, and wars. This year, the nonprofit estimates that it raised and spent $420 million, including on more than 170 million meals distributed to Ukrainians since the invasion of Ukraine. Continued here

The next evolution of digital money? It's happening now In October 2020, the Bahamas released a new kind of digital currency: “sand dollars.” These digital tokens are issued by the country’s central bank and are legal tender, with the same legal status as their old-fashioned money — paper notes and coins. The sand dollar is cash; it just doesn’t have a physical form. Residents of the Bahamas can now download an e-wallet onto their phones, load it with sand dollars, and spend away with a simple tap. For now, only two countries have officially launched such central bank digital currencies (CBDCs): the Bahamas and Nigeria. But many more are actively running CBDC trials, including China and the countries of the Eastern Caribbean Currency Union. More than 100 countries are exploring the idea. In the US, the Federal Reserve this January issued a discussion paper on CBDCs, considering all the risks and opportunities. Continued here

The Twitter Bubble Let Democrats Defy Political Gravity As political theater goes, Republican congressional candidate Joe Kent’s Election Day Twitter thread listing all the evils that his Democratic opponent Marie Gluesenkamp Perez would bring to Washington’s third District was standard fare. It prominently featured a photoshopped image of Perez driving a light-rail train surrounded by pastiched images of rioting and homelessness in neighboring Portland, Oregon—suggesting with all the subtlety of a tactical nuke that her support for a TriMet light-rail extension into Vancouver would bring Armageddon. Among the most heinous passengers on Gluesenkamp-Perez’s train from hell? “Puberty blockers and ‘trans’ surgery for minors without parental consent” and “biological men competing in girl’s sports and accessing women-only spaces.” Kent lost this formerly safe seat in one of the biggest upsets of the 2022 election. And he is far from the only Republican with a weird fixation on trans kids and their genitalia to lose an otherwise winnable race. Democrats won Michigan in a sweep, keeping the governor’s mansion, attorney general and secretary of state’s offices, a majority of the state’s Congressional seats, and majorities in the State House and Senate. The latter was a feat that had eluded Michigan Democrats for nearly 40 years. Afterward, Michigan Republican Party Chief of Staff Paul Cordes released a memo blaming his party’s dismal performance in what was supposed to be a “red wave” election on its excessive focus on “red meat” culture war politics. On trans politics he was blunt: “There were more ads on transgender sports than inflation, gas prices and bread and butter issues that could have swayed independent voters. We did not have a turnout problem—middle of the road voters simply didn’t like what [GOP gubernatorial candidate] Tudor [Dixon] was selling.” Continued here

The Director of 'Pentiment' Wants You to Know How His Characters Ate Obsidian Entertainment’s latest game, Pentiment, takes its title from the term pentimento, a change made by an artist while painting. Its origin is the Italian word pentirsi, which means to change one’s mind or repent. Pentiment’s aim is to show how history, like oil on a canvas, can be covered, then rediscovered or forgotten. The game, which has been getting rave reviews, is set in 16th-century Bavaria in the Holy Roman Empire, an area that’s now part of Germany. The player takes control of Andreas Maler, a journeyman artist with a university education, embroiled over 25 years in a series of murders and scandals that take place in the fictional locations of Kiersau Abbey and Tassing. Inspired by Umberto Eco’s The Name of the Rose, the game tries, as Eco’s novel did, to capture the texture of history, the traces of font and ink, of manuscripts and print wood cuts. Continued here

Will physics prevent SpinLaunch from succeeding? It’s long been the dream of humanity to escape the bonds of Earth’s gravitational pull, paving the way for us to explore the vast reaches of space that lie beyond our world. Beginning in the 20th century, we started to achieve this dream by leveraging the power of rocket technology, where we’d burn fuel to provide a large and constant acceleration to a payload, eventually taking it above Earth’s atmosphere and either into orbit around our planet or — more ambitiously — to escape from our planet’s gravity entirely. However, rocket launches, even when the launch vehicle is salvageable and reusable, are tremendously resource-intensive, expensive, and environmentally unfriendly. Since the mid-20th century, numerous alternative technologies have been proposed to send objects to space, but none have yet achieved that goal as of 2022. One company aims to change that in the coming few years: SpinLaunch. Ideally, they’ll build a full-scale version of their modestly-sized working prototype to spin objects up to speeds of 5,000 miles-per-hour (8,100 kph) and launch them upward, where a small booster will take them all the way into space. It’s an ambitious goal, but the laws of physics might be standing in the way. Here’s why. Continued here

Known as Warhol's Muse, Edie Sedgwick Was an Artist Herself Edie Sedgwick was the “It Girl” of the mid-1960s. Known primarily as pop artist Andy Warhol’s muse, she starred in many of his movies, including Poor Little Rich Girl, Vinyl and Chelsea Girls. Her fame was a bright flash in the pan, spanning just a few short years until her death in 1971, at age 28. But in that time, her celebrity reached mythic proportions and propelled Warhol’s career to the next level. Several Bob Dylan songs, including Like a Rolling Stone and Just Like A Woman, are rumored to be about Sedgwick; so is the Velvet Underground’s Femme Fatale.  Continued here

Inside a boot camp for Chinese TikTok sellers bringing live e-commerce to the U.S. Jacqueline Zhuang made her debut as a TikTok live-shopping host from a studio in Guangzhou, promoting the sequined red dress she was wearing, in front of a rack of glittery clothes. “If you wear it to your bestie’s wedding, I’m sure the men stare at you, and the girls envy you,” Zhuang declared passionately in English. Encouraging voices cheered her on from off camera. “For the friends who pick it, I will have an extra surprise for you,” she added. Only a week earlier, 30-year-old Zhuang had quit her decade-long career as a newspaper journalist and television anchor for what she believes is a career of the future — hosting live streams on TikTok to sell things to shoppers in the West. To set herself up for success, Zhuang joined a bootcamp, a two-day crash course in sales tactics and English-language internet slang to entice Western shoppers. Promoters of the course promised to show Zhuang and the other attendees — factory owners, teachers and a former flight attendant — everything they needed to know to sell Chinese products to English-speaking consumers on the world’s most popular social media platform.
