‘Timber cities’ might help decarbonize the world

‘Timber cities’ might help decarbonize the world

Inside Climate News reports: Buildings constructed with more wood, and less cement and steel, would help decarbonize the construction and housing industries in line with global goals to cut greenhouse gas emissions 50 percent by 2030 and reach net zero emissions by 2050, new research shows. The paper, published Aug. 30 in Nature Communications, explains that building mid-rise wood dwellings to meet the demand from rapidly expanding urban populations could avoid about 100 gigatons of carbon dioxide emissions through 2100—about…

NASA to crash $330m spacecraft into asteroid to see if impact can alter course

NASA to crash $330m spacecraft into asteroid to see if impact can alter course

The Guardian reports: In a few weeks, Nasa controllers will deliberately crash their $330m Dart robot spacecraft into an asteroid. The half-tonne probe will be travelling at more than four miles a second when it strikes its target, Dimorphos, and will be destroyed. The aim of this kamikaze science mission is straightforward: space engineers want to learn how to deflect asteroids in case one is ever discovered on a collision course with Earth. Observations of Dart’s impact on Dimorphos’s orbit…

Putin scrambles for high-tech parts as his arsenal goes up in smoke

Putin scrambles for high-tech parts as his arsenal goes up in smoke

Politico reports: It’s the microchips that look set to get Vladimir Putin in the end. Six months into its invasion of Ukraine, Russia is being throttled by a severe technology deficit inflicted by sanctions. Having fired off (or lost in combat) way more of their missile firepower than they originally anticipated, Moscow’s soldiers are now increasingly relying on ancient stocks of primitive Soviet-era munitions while Western-armed Ukrainian forces are battling to turn the tide in a southern counteroffensive with pinpoint…

The super-rich ‘preppers’ planning to save themselves from the apocalypse

The super-rich ‘preppers’ planning to save themselves from the apocalypse

Douglas Rushkoff writes: As a humanist who writes about the impact of digital technology on our lives, I am often mistaken for a futurist. The people most interested in hiring me for my opinions about technology are usually less concerned with building tools that help people live better lives in the present than they are in identifying the Next Big Thing through which to dominate them in the future. I don’t usually respond to their inquiries. Why help these guys…

What is Fog Data Science? Why is this surveillance company so dangerous?

What is Fog Data Science? Why is this surveillance company so dangerous?

Electronic Frontier Foundation reports: An EFF investigation of public records acquired from dozens of state and local law enforcement agencies has uncovered a widely-used mass surveillance technology. Americans are accustomed to hearing about how the National Security Agency (NSA), the Central Intelligence Agency (CIA), and even the domestically-focused Federal Bureau of Investigation (FBI) have illegally swept up massive amounts of data on people living in the United States—but what about the state and local police? Fog Data Science LLC, a…

California’s gas car ban will change how everyone drives

California’s gas car ban will change how everyone drives

Vox reports: California, the state that buys the most cars and trucks in the United States, will ban the sale of fossil fuel-powered vehicles by 2035. This represents the largest government move against gasoline and diesel to date, with the potential to ripple throughout the country and the global auto industry. The California Air Resources Board, which regulates pollution in the state, voted unanimously on Thursday to approve a proposal that will require 100 percent of all cars sold in…

California plans to ban the sale of new gasoline cars

The New York Times reports: California is expected to put into effect on Thursday its sweeping plan to prohibit the sale of new gasoline-powered cars by 2035, a groundbreaking move that could have major effects on the effort to fight climate change and accelerate a global transition toward electric vehicles. “This is huge,” said Margo Oge, an electric vehicles expert who headed the Environmental Protection Agency’s transportation emissions program under Presidents Bill Clinton, George W. Bush and Barack Obama. “California…

Undersea internet cables can detect earthquakes — and may soon warn of tsunamis

Undersea internet cables can detect earthquakes — and may soon warn of tsunamis

Jeffrey Marlow writes: Somewhere beneath the Adriatic Sea, a rogue block of the African tectonic plate is burrowing under southern Europe, stretching Italy eastward by a few millimetres each year. On October 26, 2016, the stress triggered an earthquake in the Apennine Mountains, one in a series of quakes which toppled buildings in Italian towns. On the day of the tremor, Giuseppe Marra, a principal research scientist at the National Physical Laboratory in Teddington, England, was running an experiment that…

Carbon-reduction plans rely on technology that doesn’t exist

Carbon-reduction plans rely on technology that doesn’t exist

Naomi Oreskes writes: At last year’s Glasgow COP26 meetings on the climate crisis, U.S. envoy and former U.S. secretary of state John Kerry stated that solutions to the climate crisis will involve “technologies that we don’t yet have” but are supposedly on the way. Kerry’s optimism comes directly from scientists. You can read about these beliefs in the influential Intergovernmental Panel on Climate Change (IPCC) Integrated Assessment Models, created by researchers. These models present pathways to carbon reductions that may…

Geothermal heating and cooling: Renewable energy’s hidden gem

Geothermal heating and cooling: Renewable energy’s hidden gem

Yale Climate Connections reports: Often described as a giant tower of Jenga blocks, Boston University’s Center for Computing and Data Sciences shows no outward signs of leading the race to sustainable energy design. No rooftop wind turbines grace its heights; no solar panels are mounted on the multiple roof decks jutting out from the building’s core. What makes this building unique lies deep underground, where water circulating through 31 geothermal boreholes will supply 90 percent of its heating and cooling…

Inside the UK’s Silicon Valley for nuclear fusion, where unlimited energy is becoming a reality

BBC Science Focus reports: Flick through any collection of popular science magazines from the last 50 years and the chances are that you will encounter a feature about nuclear fusion. Nuclear fusion is the process of joining lightweight atoms together to release energy; it is the reason the Sun and the rest of the stars shine, and recreating that process on Earth promises an abundant form of low-carbon energy. As you look through the archival material, keep an eye open…

Under capitalism, the colonization of space means the destruction of Earth

Under capitalism, the colonization of space means the destruction of Earth

Srećko Horvat writes: In February 2022, the Adam Smith Institute published a report claiming that the Moon should be privatized to help wipe out poverty on Earth. According to the report, the Moon should be divided into parcels of land and assigned to various countries to rent out to businesses, which would boost space tourism, exploration, and discovery. For now, thankfully, there is a treaty that stands in the way of such plans. The Outer Space Treaty was drawn up…
