Drivel...

I say we take off and nuke the entire site from orbit

It's the only way to be sure

I love fusion explosions, I love fission explosions.

I've got my fingers crossed for a Snowpiercer set up.

The point is that it's a passive process, not an active one. No need for pumping.

Water is so much denser than air that you do get more exposure time per unit time.

This is by far the most practical "geoengineering" solution I've seen, far better than aerosols over the arctic, space shades or whatever. The ecological damage is comparatively miniscules.

And even then... quite a engineering feat. Nukes are actually "cheap" to scale up (a small bomb can catalyze big, cheap cores), but burying that much volume "3-5 km into the basalt-rich seafloor" is not something anyone is set-up to do.

But by far the hardest part is... information. Much of the world doesn't even believe in climate change anymore, and by the time they do, it will be too late.

I guess Trump could add a new canal to the Red Sea, as per an old proposal involving nukes to dig it. Considering this administration, I wouldn't be surprised at all.

Carbon sequestration is not going to solve global warming. CO2 is less than 2% of atmosphere. Even if you pass a shitton of air through the strata the difference will be negligible.

Well, I'm sure controlled slow-paced mining is more energy efficient and will emit less carbon to create...

But I'm not stopping that guy. Go on. I'll just watch from a safe distance.
