Geo-engineering

Geo-engineering involves purposefully attempting to cool the climate through planetary-scale actions like blocking sunlight by stationing mirrors in space. Other fixes include seeding the seas with iron to help plankton absorb more greenhouse gases, and injecting sulfur into the upper atmosphere to create sunlight-deflecting clouds. These are clearly last resorts, and scientists have no idea whether the cure could be worse than the disease, but the very fact that experts now support researching into geo-engineering shows just how desperate the climate crisis has become. The image below illustrates some of the ways geo-engineering is acheived.
