Geoengineer the Planet? More Scientists Now Say It Must Be an Option

Summary

Notes

For a long time it's been considered SciFi

But time is no longer on our side: cutting emissions is no longer enough

China also has an active government funded program

In 1977: Cesare Marchetti of the Austria-based International Institute for Applied Systems Analysis discussed ways of catching all of Europe’s CO2 emissions and injecting them into sinking Atlantic Ocean currents.

🤔

Could be a good example to discuss history

Emissions are still growing when we should be halving them by 2030 ...

Afforestation and restauration of ecosystems to boost their Carbon capture could cover 33% of emission cuts needed by 2030
