Tomas Pueyo in Uncharted Territories:
In We Can Already Stop Climate Change If We Want To, I explained that we have a path to solve climate change (renewables, nuclear, batteries, olivine weathering), but it will take at least a few decades to get there. In the meantime, CO2 emissions will keep growing, there’s nothing we can do to reverse them fast enough, and global temperatures will keep increasing.
There is only one thing we can do to avoid these potentially catastrophic consequences: Cooling the Earth artificially until we get CO2 levels in hand. And the best way we know to do that is sending SO2 to the stratosphere.
I outlined that solution in the article linked above, but I didn’t go in depth, and many of you had questions:
Does it really work? How?
Is this really the best solution? What are the alternatives?
How safe is it? What are the downsides?
Will states allow this? Is it legal?
How much will it cost?
Where should we release this SO2?
So I dove into this, talked with the only company that I know that is trying to do this at scale, and as a result of this deep dive, I am trying to invest in the company. Here’s what I found…
