At this point we all know we gotta pull all that extra co2 back out of the atmosphere and store it long term.
Not only do we need to pull co2 out of the atmosphere, but we also likely have to start spraying ocean water into the upper atmosphere to help keep things halfway stable.
Maybe start doing tests on ocean iron seeding as well to promote open ocean algae blooms. (there's been some research, but it was done in about the single worst way possible)
The point is, we've been accidentally geoengineering the planet for centuries, we need to stop that, and do it with intention.
