Can high-tech solutions help protect the climate? What would be the side effects of further human intervention in nature?

Attempts are being made to reduce CO2 in the atmosphere with technical solutions. For example, new carbon capture technology can extract CO2 from air and water, although the amount currently captured is minimal and insufficient to prevent the climate crisis and its consequences.
However, there is no shortage of ideas. Adding basalt dust to agricultural fields not only fixes carbon dioxide but also maintains soil fertility. Biochar, made from organic waste, has a similar effect.
Some ideas are more daring: a protective screen of particles in the upper layers of the atmosphere could filter sunlight, as seen during the eruption of the Pinatubo volcano in the Philippines in 1991. The millions of tons of Sulfur dioxide released into the stratosphere cooled the Earth. significantly.
Theoretically, planes could be used to deliver the particles. But experts warn that the consequences on humans and weather would be felt worldwide and could never be fully controlled.
