Meta’s former CTO has a new $50 million project: ocean-based carbon removal

The news: A nonprofit formed by Mike Schroepfer, Meta’s former chief technology officer, has spun out a new organization aimed at speeding up research into ocean alkalinity enhancement—a potential way to use the seas to suck up and store away even more carbon dioxide. The Carbon to Sea Initiative will get $50 million over the next five years to pursue that goal.

How it works: Ocean alkalinity enhancement refers to various ways of adding alkaline substances, like olivine, basalt, or lime, into seawater. These basic materials bind with dissolved inorganic carbon dioxide in the water to form bicarbonates and carbonates, ions that can persist for tens of thousands of years in the ocean. As those CO2-depleted waters reach the surface, they can pull down additional carbon dioxide from the air to return to a state of equilibrium. 

Why it matters: While such projects would be challenging to scale, climate modelers are optimistic about the method’s potential. Read the full story.

Elon Musk’s quiet, untweeted China trip

Ever since China lifted most of its pandemic-era travel restrictions in January, foreign executives have been flocking in—including one Elon Musk. He paid a three-day visit to China last week to meet with high-ranking government officials. Unusually for him, he stayed off Twitter the entire time. 

However, from the public readouts posted by Chinese government websites and sightings of Musk shared on Chinese social media, we can reconstruct his trip. Read the full story.

The big story
 

The uneasy coexistence of Yandex and the Kremlin

August 2020

While Moscow was under coronavirus lockdown between March and June 2020, the Russian capital emptied out—apart from the streams of cyclists in the trademark yellow uniform of Yandex’s food delivery service.

Often referred to in the West as Russia’s Google, Yandex is really more like Google, Amazon, Uber, and maybe a few other companies combined. It’s a Russian Silicon Valley unto itself. 

But Yandex’s success has come at a price. The Kremlin has long viewed the internet as a battlefield in its escalating tensions with the West and has become increasingly concerned that a company like Yandex, with the heaps of data it has on Russian citizens, could one day fall into foreign hands.
