Our Axios Voices conversation on geoengineering.

The Paris climate agreement and some nations, including the U.S, recognize certain geoengineering projects as potentially legitimate, but the legal status of technologies to deflect the sun's radiation is wholly undefined despite carrying geopolitical and moral risks.

Why it matters: Solar radiation management, in which the sun's light is reflected by mirrors or particles deployed in the atmosphere, could have terrible environmental and societal consequences. It could be weaponized and lead to conflict between nations. Even if the risks are overblown, merely talking about and conducting research into geoengineering may weaken support for limiting emissions via renewable energy and conservation, methods we know work. When geoengineering is presented to people as a potential solution to climate change, their support for mitigation measures falls.

Bottom line: We need responsible communication. Even if solar radiation management never becomes a physical reality, how it is portrayed by scientists, governments, and corporations could have a profound effect on how the world addresses climate change.

General Motors tries to revive incendiary lawsuit vs. Fiat Chrysler

General Motors is trying to revive an incendiary lawsuit against Fiat Chrysler Automobiles with explosive new allegations including bribes paid from secret offshore bank accounts and a union official acting as a double agent between the two automotive giants.

Why it matters: The extraordinary legal battle is occurring amid earth-shaking changes in the global auto industry that threaten to turn both litigants into dinosaurs if they aren't nimble enough to pivot to a future where transportation is a service, cars run on electrons and a robot handles the driving.

Cuomo says all New York schools can reopen for in-person learning

New York Gov. Andrew Cuomo announced Friday that all school districts across the state can choose to reopen for in-person learning because it has so far maintained low enough coronavirus transmission rates.

Why it matters: It’s another sign that the state, once the global epicenter of the pandemic, has — at least for now — successfully curbed the spread of the virus even as infections have surged elsewhere around the country.
