assuming this is serious... There is no silver bullet - you can't just build a 10bn$ nuclear bomb programm and call it a day. All the other means are still needed to transition away from fossil fuel. The earlier we start the better.

Very much this! This is about removing (if it at wall will do that) without fixing the root cause. How deep can you put your head in the ground? It reminds of the Matrix where they scorched the skies to remove solar power capabilities as a way to block the enemy.

I find it interesting ever more risky way to sequester carbon are invented. Instead of making adding biochar to farm land an agricultural subsidy. A simple, extremely low risk policy, that is a local subsidy and does create international trade conflicts like other subsidies can. And it does not affect any wilderness. And in hot humid climates is proven to increase fertility. Or a bit risky we could fertilize the open…

Does biochar remain in ground for long? How quickly does it decompose and rot?

7 to 10-ish years from what I recall. Which is another thing that makes it so low risk. If you stop the subsidy it goes away with a few years.

That is pretty variable I would think due to ground composition and how complete the char burn is. In my anecdotal experience, if you do a low grade charcoal that still has a decent amount of oils in it like a lot of old-school burn wood and bury it in earth or drench in water, most of it will have broken down to invisibility after just a few years or so mixed into the ground. However charcoal that I have burned in a container sealed from air ingress and using a secondary source of heat until the wood stops venting any gases and is nearly pure carbon, I still see decent size chunks of it in my garden areas over 2 decades later, and no reason to expect it to not still be there even 50+ years from now.
