So many simple and easy geo engineering solutions floating around 🙄
Climate
Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:

How much each change to the atmosphere has warmed the world:

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
How gives a fuck what one tech company says it can do? Tech companies say they can do all kinds of things they haven't delivered on while humanity pours its resources into those dead ends, getting us ever closer to environmental bankruptcy in the process. There's no paper, no scientific peer review and no transparency. This is a half baked attempt at defending an untenable attitude towards the planet as our species' all you can eat.
Someone didn’t watch Snowpiercer.
That's relatively low risk. Bigger problem is that if we depend on a system like this, we need to keep it operational for as long as CO2 concentration remains elevated. And that's a lot longer than civilizations last.
Every decade we can delay climate change takes immense pressure off ecosystems and human migration pressures, giving them time to adapt more gradually. If this could work safely and didn't take money and effort away from CO2 reduction, then it would be good even if it eventually comes to an end.
That said, the "if" is false. Like plastic recycling, geoengineering is a way for people to accept pollution by pretending it's preventable. The company in question isn't selling a solution, they are selling a greenwashing ad campaign. And the NYT is already participating in the ad campaign by publishing the article.
