SEC wants Elon Musk held in contempt of court over tweets – Roadshow

The SEC has asked a judge to hold Elon Musk in contempt for violating his settlement with the agency

The U.S. Securities and Exchange Commission asked a judge to hold Elon Musk in contempt for violating his Oct. 16 settlement with the agency

Bloomberg News reported the news a bit ago. We’ve since obtained the agency’s complaint, though it is declining comment.

Tesla has yet to respond to our requests for more information.

At the crux of things: Last Tuesday night, Musk tweeted out to his 24 million followers that Tesla would make around 500,000 cars this year, correcting himself hours later to clarify that he meant the company would be producing at an annualized rate of 500,000 vehicles by year end.

The next morning, Tesla announced that its general counsel, Dane Butswinkas, is leaving after just months on the job.

Butswinkas had reportedly battled on Musk’s behalf with the SEC last year, after Musk infamously tweeted in August that he had “funding secured” to take the company private when he had not.

In the end, Musk and Tesla settled without admitting wrongdoing. Still, Tesla had to pay a $20 million fine; Musk had to agree to step down as Tesla chairman for a period of at least three years; the company had to appoint two independent directors to the board; and Tesla was also told to put in place a way to monitor Musk’s statements to the public about the company, including via Twitter.

In November, Tesla announced that Australian telecom executive and chair of Tesla’s audit committee Robyn Denholm would take over from Musk as chair of the company. In December, it appointed two independent directors to its board: Larry Ellison, executive chairman of Oracle, and Kathleen Wilson-Thompson, executive vice president of Walgreens Boots Alliance.

It’s Musk’s admission that he didn’t obtain pre-approval for his tweet last week that the SEC considers “clear and convincing evidence that he violated the court’s final judgement,” with the SEC adding in its filing that he has “not diligently attempted to comply” with that specific ruling.

Perhaps unsurprisingly, Musk hasn’t commented on the motion on Twitter, though he did write somewhat cryptically a couple of hours ago that “Fate loves irony. Frankly, too much.”

Musk was less circumspect last year, telling “60 Minutes” in a segment that aired in early December, “I want to be clear: I do not respect the SEC, I do not respect them.”

Typically, if a person is found to be guilty of contempt of court, he or she may face a fine, jail time, or other penalty.

Climate change kills off clouds over the ocean in new simulation

We all know climate change is affecting weather systems and ecosystems around the world, but exactly how and in what way is still a topic of intense study. New simulations made possible by higher-powered computers suggest that cloud cover over oceans may die off altogether once a certain level of CO2 has been reached, accelerating warming and contributing to a vicious cycle.

A paper published in Nature details the new, far more detailed simulation of cloud formation and the effects of solar radiation thereupon. The researchers, from the California Institute of Technology, explain that previous simulation techniques were not nearly granular enough to resolve effects happening at the scale of meters rather than kilometers.

These global climate models seem particularly bad at predicting the stratocumulus clouds that hover over the ocean — and that’s a big problem, they noted:

As stratocumulus clouds cover 20% of the tropical oceans and critically affect the Earth’s energy balance (they reflect 30–60% of the shortwave radiation incident on them back to space1), problems simulating their climate change response percolate into the global climate response.

A more accurate and precise simulation of clouds was necessary to tell how increasing temperatures and greenhouse gas concentrations might affect them. That’s one thing technology can help with.

Thanks to “advances in high-performance computing and large-eddy simulation (LES) of clouds,” the researchers were able to “faithfully simulate statistically steady states of stratocumulus-topped boundary layers in restricted regions.” A “restricted region” in this case means the 5×5-km area simulated in detail.

The improved simulations showed something nasty: when CO2 concentrations reached about 1,200 parts per million, this caused a sudden collapse of cloud formation as cooling at the tops of the clouds is disrupted by excessive incoming radiation. Result (as you see at top): clouds don’t form as easily, letting more sun in, making the heating problem even worse. The process could contribute as much as 8 or 10 degrees to warming in the subtropics.

Naturally there are caveats: simulations are only simulations, though this one predicted today’s conditions well and seems to accurately reflect the many processes going on inside these cloud systems (and remember — inherent error could be against us rather than for us). And we’re still a ways off from 1,200 PPM; current NOAA measurements put it at 411 — but steadily increasing.

So it would be decades before this took place, though once it did it would be catastrophic and probably irreversible.

On the other hand, major climatic events like volcanoes can temporarily but violently change these measures, as has happened before; the Earth has seen such sudden jumps in temperature and CO2 levels before, and the feedback loop of cloud loss and resulting warming could help explain that. (Quanta has a great write-up with more context and background if you’re interested.)

The researchers call for more investigation into the possibility of stratocumulus instability, filling in the gaps they had to estimate in their model. The more brains (and GPU clusters) on the case, the better idea we’ll have of how climate change will play out in specific weather systems like this one.

Ford partners with geocoding startup what3words

Ford is partnering with what3words to give drivers access to the startup’s novel addressing system.

Under the partnership, drivers will be able to connect to the free what3words app — on an iOS or Android device — to their vehicle via their SYNC 3 infotainment platform. Drivers can find the three-word address on website contact pages, guidebooks and business cards. Drivers can enter the addresses via voice or text input and receive directions through the vehicle’s navigation system.

The startup, founded in 2013, has divided the entire world into 57 trillion 3-by-3 meter squares and assigned three words to each one. Users of the what3words app, which is available in 26 languages, has been adopted by logistics, travel, automotive and humanitarian organizations because it provides exact locations anywhere in the world.

The system is used by Lonely Planet, which has rolled out three-word addresses for each of its listings, as well as Mercedes-Benz, ride-hailing app Cabify, the UN, Red Cross and TomTom.

The startup has also attracted an interesting mix of investors, most recently Sony’s venture capital arm. And last year, Daimler took a 10 percent stake in what3words, following an announcement in 2017 to integrate the addressing system into Mercedes’ new infotainment and navigation system — called the Mercedes-Benz User Experience, or MBUX. MBUX is now in the latest Mercedes A-Class and B-Class cars and Sprinter commercial vehicles.

“We are more mobile than ever before, but with that comes its challenges. The growing traction that what3words is gaining within the automobility industry is a testament to how we are improving journeys and customer experiences,” CEO and co-founder Chris Sheldrick said.

What3words will initially be available to Ford owners in the U.K. and Ireland, Germany, Spain, the U.S. and Mexico. More markets and languages will follow later in the year. The addressing system can be downloaded for free on iOS and Android.
