Just a very noob question here. When carbon is released into the atmosphere where and how does it disperse? Can we expect it to gradually concentrate in lower elevations or in certain geographical traps?
Drawdown works in the opposite way. By reducing the concentration in a single area, the global concentration would work to equilibrate, so more CO2 would "fill the void", and if more drawdown keeps happening, than more CO2 will keep equilibrating and filling voids, and more capture will happen.
