Fine-tuning the Climate

This documentary investigates geoengineering, a field of scientific and technological intervention aimed at mitigating climate change. The program explores various approaches to geoengineering, examining their scientific feasibility and potential societal implications. It addresses the premise that current efforts to reduce CO2 emissions may be insufficient to prevent irreversible climate change, prompting exploration into more radical technological solutions.

The investigation features science journalist Ingolf Baur, who travels to Switzerland, Iceland, the United States, and Peru to meet with scientists involved in leading geoengineering projects. The documentary differentiates between two primary strategies: carbon dioxide removal, which involves extracting CO2 from the atmosphere and sequestering it, and solar radiation management, which seeks to reduce the amount of solar energy absorbed by the Earth. Specific examples include a project in Iceland that converts atmospheric CO2 into stone and experiments in solar geoengineering, such as those proposed by David Keith of Harvard University, which involve stratospheric aerosol injection to reflect sunlight.
