1. A secretive geoengineering startup unveils its technology

Stardust Solutions, the startup led by former Israeli government physicians that’s promising technology that can reflect sunlight back into space and artificially cool the planet, has released information on the proprietary particle it wants to spray in the atmosphere. On Thursday, the company laid out blueprints for two separate particles, both nearly spherical and half a micron in size. The materials are made from natural compounds frequently used in toothpaste and food additives. The first-generation technology is amorphous silica, which the company called “fully bio-safe, manufacturable at scale today, and at a very advanced stage of validation.” The second-generation formulation adds a calcium carbonate core inside the silica shell. “The reason is straightforward: At high doses, any particle that absorbs a meaningful amount of the Earth’s outgoing infrared radiation will heat the stratosphere, which is a side effect you want to avoid,” the company said. “Gen 2 is as reflective to the incoming sunlight (visible light), but is more transparent to the outgoing infrared radiation, so it can be deployed at higher doses without that heating effect.”

1. Trump kicks off summit with Xi Jinping in China

President Donald Trump formally began talks with Chinese president Xi Jinping today as the leaders of the world’s two largest economies seek some kind of rapprochement after more than a year of escalating battles over trade. The discussions are expected to cover a range of topics, including Taiwan’s sovereignty and the market dominance over critical minerals that Foreign Policy called Beijing’s “most potent” tool in the trade negotiations. Indeed, China’s control over critical minerals means Xi “will have the upperhand,” according to the Council on Foreign Relations, which noted that Trump folded last year in his trade battle with Xi once Beijing threatened to restrict flows of rare earths.
