The biggest threat of co2 emmisions is ocean acidifcation. A collapse of the ocean ecosystem would be devastating to the rest of the planet. A warmer planet sucks, but dead phytoplankton would result in a global plumment in O2 production.
The concentration isn’t as important as the difficulty to remove it. It’s still a hard problem, but rock weathering is one way to accomplish it, but it would need a lot of exposed rock surface.
I don’t know. What do you think is the concentration of CO2 in the sea water? I am just not convinced.
