How many users does Facebook have? The company struggles to figure it out

The Wall Street Journal reports: Facebook is struggling to detect and deal with users’ creating multiple accounts on its flagship platform, according to internal documents that raise new questions about how the social-media giant measures its audience. An internal Facebook presentation this spring called the phenomenon of single users with multiple accounts “very prevalent” among new accounts. The finding came after an examination of roughly 5,000 recent sign-ups on the service indicated that at least 32% and as many as…

What Lebanon, Hong Kong, and Afghanistan have lost

What Lebanon, Hong Kong, and Afghanistan have lost

Kim Ghattas writes: From my home in Beirut, I think of Hong Kong all the time. Even though I’ve never been and have no real ties to it, I feel as though I have a stake in its future. I stare at news headlines that read, “Hong Kong Families, Fearing a Reign of Terror, Prepare to Flee the City,” and feel a strange, visceral sense of familiarity. I’ve become obsessed with trying to understand—to feel—Hong Kongers’ angst as their city…

People mistake the internet’s knowledge for their own

People mistake the internet’s knowledge for their own

John Timmer writes: Many of us make jokes about how we’ve outsourced part of our brain to electronic devices. But based on a new paper by the University of Texas at Austin’s Adrian Ward, this is just a variation on something that has been happening throughout human history. No person could ever learn everything they need to know. But that’s OK, according to Ward: “No one person needs to know everything—they simply need to know who knows it.” Over time,…

The world’s second-largest rainforest is key to limiting climate change — it needs urgent study and protection

The world’s second-largest rainforest is key to limiting climate change — it needs urgent study and protection

Lee J. T. White et al write: Earth’s second-largest expanse of tropical forest lies in central Africa, in the Congo Basin. The region supports the livelihoods of 80 million people. The rainfall that the forest generates as far away as the Sahel and the Ethiopian highlands supports a further 300 million rural Africans. These forests are crucial to regulating Earth’s climate, and are home to forest elephants, gorillas and humans’ closest relatives, chimpanzees and bonobos. Such services to people and…

Manchin leads opposition to Biden’s climate bill, backed by support from oil, gas and coal

Manchin leads opposition to Biden’s climate bill, backed by support from oil, gas and coal

The Guardian reports: In the tumult of negotiations over the most consequential climate legislation ever proposed in the US, there is growing scrutiny of the fossil fuel industry connections of the man poised to tear down the core of the bill – the West Virginia senator Joe Manchin. Manchin, a centrist Democrat, has objected to key provisions of a multitrillion-dollar reconciliation bill that would slash planet-heating emissions and help the US, and the world, to avert catastrophic climate breakdown. In…

How Joe Manchin and Republicans could destroy the world

How Joe Manchin and Republicans could destroy the world

Brian Kahn writes: The United Nations climate conference happening in Glasgow in less than two weeks will essentially chart a course for humanity for generations to come. That’s because this decade is one where the world must start cutting carbon emissions by nearly 8% per year or blow past a key climate guardrail. The U.S. was slated to be a big player, showing up to the meeting known as COP26 with a major new tool to reduce carbon pollution from…

How chemical companies avoid paying for pollution

How chemical companies avoid paying for pollution

The New York Times reports: One humid day this summer, Brian Long, a senior executive at the chemical company Chemours, took a reporter on a tour of the Fayetteville Works factory. Mr. Long showed off the plant’s new antipollution technologies, designed to stop a chemical called GenX from pouring into the Cape Fear River, escaping into the air and seeping into the ground water. There was a new high-tech filtration system. And a new thermal oxidizer, which heats waste to…

Trump organization, already under indictment, faces new criminal inquiry

The New York Times reports: Former President Donald J. Trump’s family business, which is already under indictment in Manhattan, is facing a criminal investigation by another prosecutor’s office that has begun to examine financial dealings at a golf course the company owns, according to people with knowledge of the matter.

The truth about humanity’s deep past

The truth about humanity’s deep past

David Graeber and David Wengrow write: In some ways, accounts of “human origins” play a similar role for us today as myth did for ancient Greeks or Polynesians. This is not to cast aspersions on the scientific rigour or value of these accounts. It is simply to observe that the two fulfil somewhat similar functions. If we think on a scale of, say, the last 3m years, there actually was a time when someone, after all, did have to light…

Mapping the heliosphere, which shields our solar system from harmful cosmic rays

Virat Markandeya writes: David McComas has a favorite “astrosphere,” the environment created by a star’s stellar wind as it buffets the surrounding interstellar medium. It belongs to a star named Mira. In an image from 2006, Mira is heading to the right, at 291,000 miles an hour, five times the speed our sun ambles through its local interstellar cloud in the Milky Way. You can make out a “bow shock” forming ahead of the star, like one would ahead of…

Why longtermism is the world’s most dangerous secular credo

Why longtermism is the world’s most dangerous secular credo

Phil Torres writes: [O]ver the past two decades, a small group of theorists mostly based in Oxford have been busy working out the details of a new moral worldview called longtermism, which emphasizes how our actions affect the very long-term future of the universe – thousands, millions, billions, and even trillions of years from now. This has roots in the work of Nick Bostrom, who founded the grandiosely named Future of Humanity Institute (FHI) in 2005, and Nick Beckstead, a…

Democrats scramble for climate Plan C as Manchin dashes their dreams

Democrats scramble for climate Plan C as Manchin dashes their dreams

Politico reports: Joe Manchin is hearing a dire pitch from his colleagues: Don’t blow our chance to save the world. After Manchin rejected a centerpiece of President Joe Biden’s climate plan and rebuffed a separate carbon tax Tuesday, Senate Democrats are urgently pressing their West Virginia colleague for an alternative. Biden and Democrats are trying to clinch a deal on Biden’s larger social spending bill, but the climate plank has become a serious question mark due to Manchin. And some…

Brazilian leader’s pandemic handling draws explosive allegation: mass homicide

The New York Times reports: A Brazilian congressional panel is set to recommend mass homicide charges against President Jair Bolsonaro, asserting that he intentionally let the coronavirus rip through the country and kill hundreds of thousands in a failed bid to achieve herd immunity and revive Latin America’s largest economy. A report from the congressional panel’s investigation, excerpts from which were viewed by The New York Times ahead of its scheduled release this week, also recommends criminal charges against 69…

The Trump administration used its food aid program for political gain, congressional investigators find

ProPublica reports: A $6 billion federal program created to provide fresh produce to families affected by the pandemic was mismanaged and used by the Trump administration for political gain, a new congressional report has found. As a ProPublica investigation revealed last spring and as the new report further details, the Farmers to Families Food Box program gave contracts to companies that had no relevant experience and often lacked necessary licenses. The House Select Subcommittee on the Coronavirus Crisis, which released…
