„Engineers and scientists are trying to intervene in the Earth’s geochemical cycles. Because it appears efforts to cut CO2 won’t suffice to avoid irreversible climate change. But does geoengineering offer a real solution? Or is it just human hubris?

Some scientists believe that we need to explore radical, and perhaps dangerous, technologies in order to be able to lower the earth’s temperature through geoengineering in the near future. Science journalist Ingolf Baur explores the feasibility and risks of leading geoengineering projects. His journey takes him to meet scientists in Switzerland, Iceland, the US and Peru. Along the way, he encounters two very different strategies: One is to fish climate-damaging CO2 from the atmosphere and sink it underground or in the deep sea. The other, and this is the far more controversial strategy, seeks to develop techniques that dim sunlight. " End of Quote

Enjoy the documentary.
