About :
New technologies are extracting CO2 from the air and water, but still in minimal quantities. It is impossible to stop the climate crisis in this way, but technical solutions are trying to reduce the amount of CO2 in the atmosphere. How can high technology really contribute to climate protection? And what consequences does changing the course of nature once again have? There are many ideas on this subject: Basalt rock dust on crops helps to remove carbon dioxide from the atmosphere and remineralises the soil, keeping it fertile. Charcoal also has a similar effect. Some of the ideas are daring: a protective screen made of particles in the upper layers of the atmosphere could dampen sunlight. The eruption of the Philippine volcano Pinatubo in 1991 demonstrated how this works. It released millions of tonnes of sulphur dioxide into the stratosphere. The result was a measurable cooling of the Earth. In theory, this would already be possible with airplanes, but experts warn that the consequences for climate and people would be felt worldwide and would be uncontrollable. #dwdocumentary #documentary #climate ـــــ DW Documentary brings you information beyond the headlines.
