There is still a crumple zone, but it doesn’t have an engine…

We’ve moved past oligarchy into kleptocracy in the last few weeks.

Not all geoengineering is the same. Beavers are geoengineers. We have already had a crazy huge impact on this planet, we should absolutely do something to mitigate these effects. A distributed (as opposed to all in one location) carbon cycle buffer is about the least harmful effect one can hope for and still have a positive impact.

Those bicarbonate ions are great for combating ocean acidification, they act as a pH buffer. Ocean acidification is rising due to increased atmospheric CO2 levels and that decrease in pH makes it harder for macro life forms to utilize carbonates to form shells and drives extinction. By increasing the concentration of bicarbonate, the carrying capacity of the ocean to absorb atmospheric CO2 without changing the pH is increased.
