Cesare Marchetti Coins the Term “Geoengineering”

Geoengineering

Coined the term “geoengineering” and proposed sequestering CO₂ in the deep ocean.

The problem of C0₂ control in the atmosphere is tackled by proposing a kind of "fuel cycle" for fossil fuels where C0₂ is partially or totally collected at certain transformation points and properly disposed of.

C0₂ is disposed of by injection into proper sinking thermohaline currents that carry and spread it into the deep ocean that has a very large equilibrium capacity.

The Mediterranean undercurrent entering the Atlantic at Gibraltar has been identified as one such current; it would have sufficient capacity to deal with all C0₂ produced in Europe even in the year 2100. [1]
